* @description
|
|
*
|
|
* This object provides a utility for producing rich Error messages within
|
|
* Angular. It can be called as follows:
|
|
*
|
|
* var exampleMinErr = minErr('example');
|
|
* throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
|
|
*
|
|
* The above creates an instance of minErr in the example namespace. The
|
|
* resulting error will have a namespaced error code of example.one. The
|
|
* resulting error will replace {0} with the value of foo, and {1} with the
|
|
* value of bar. The object is not restricted in the number of arguments it can
|
|
* take.
|
|
*
|
|
* If fewer arguments are specified than necessary for interpolation, the extra
|
|
* interpolation markers will be preserved in the final string.
|
|
*
|
|
* Since data will be parsed statically during a build step, some restrictions
|
|
* are applied with respect to how minErr instances are created and called.
|
|
* Instances should have names of the form namespaceMinErr for a minErr created
|
|
* using minErr('namespace') . Error codes, namespaces and template strings
|
|
* should all be static strings, not variables or general expressions.
|
|
*
|
|
* @param {string} module The namespace to use for the new minErr instance.
|
|
* @returns {function(string, string, ...): Error} instance

|

|

* <pre>

* // Create a new module
|

* var myModule = angular.module('myModule', []);

* // register a new service
|

* // Configure existing providers
|
|
* $locationProvider.hashPrefix('!');
|

* });

* </pre>
|
|
*
|
|
* Then you can create an injector and load your modules like this:
|
|
*
|
|
* <pre>
|
|
* var injector = angular.injector(['ng', 'MyModule'])
|
|
* </pre>
|
|
*
|

* However it's more likely that you'll just use

* {@link ng.directive:ngApp ngApp} or

|

*

* @param {!string} name The name of the module to create or retrieve.

|
* @param {Function} configFn Optional configuration function for the module. Same as

* @ngdoc function
|

* @name angular.element
|
|
* @function
|
|
*
|
|
* @description
|
|
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
|
|
*
|
|
* If jQuery is available, `angular.element` is an alias for the
|
|
* [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
|
|
* delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite."
|
|
*
|
|
* <div class="alert alert-success">jqLite is a tiny, API-compatible subset of jQuery that allows
|
|
* Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most
|
|
* commonly needed functionality with the goal of having a very small footprint.</div>
|
|
*
|
|
* To use jQuery, simply load it before `DOMContentLoaded` event fired.
|
|
*
|
|
* <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or
|
|
* jqLite; they are never raw DOM references.</div>
|
|
*
|
|
* ## Angular's jqLite
|
|
* jqLite provides only the following jQuery methods:
|
|
*
|
|
* - [`addClass()`](http://api.jquery.com/addClass/)
|
|
* - [`after()`](http://api.jquery.com/after/)
|
|
* - [`append()`](http://api.jquery.com/append/)
|
|
* - [`attr()`](http://api.jquery.com/attr/)
|
|
* - [`bind()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
|
|
* - [`children()`](http://api.jquery.com/children/) - Does not support selectors
|
|
* - [`clone()`](http://api.jquery.com/clone/)
|
|
* - [`contents()`](http://api.jquery.com/contents/)
|
|
* - [`css()`](http://api.jquery.com/css/)
|
|
* - [`data()`](http://api.jquery.com/data/)
|
|
* - [`eq()`](http://api.jquery.com/eq/)
|
|
* - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
|
|
* - [`hasClass()`](http://api.jquery.com/hasClass/)
|
|
* - [`html()`](http://api.jquery.com/html/)
|
|
* - [`next()`](http://api.jquery.com/next/) - Does not support selectors
|
|
* - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
|
|
* - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or selectors
|
|
* - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
|
|
* - [`prepend()`](http://api.jquery.com/prepend/)
|
|
* - [`prop()`](http://api.jquery.com/prop/)
|
|
* - [`ready()`](http://api.jquery.com/ready/)
|
|
* - [`remove()`](http://api.jquery.com/remove/)
|
|
* - [`removeAttr()`](http://api.jquery.com/removeAttr/)
|
|
* - [`removeClass()`](http://api.jquery.com/removeClass/)
|
|
* - [`removeData()`](http://api.jquery.com/removeData/)
|
|
* - [`replaceWith()`](http://api.jquery.com/replaceWith/)
|
|
* - [`text()`](http://api.jquery.com/text/)
|
|
* - [`toggleClass()`](http://api.jquery.com/toggleClass/)
|
|
* - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.
|
|
* - [`unbind()`](http://api.jquery.com/off/) - Does not support namespaces
|
|
* - [`val()`](http://api.jquery.com/val/)
|
|
* - [`wrap()`](http://api.jquery.com/wrap/)
|
|
*
|
|
* ## jQuery/jqLite Extras
|
|
* Angular also provides the following additional methods and events to both jQuery and jqLite:
|
|
*
|
|
* ### Events
|
|
* - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
|
|
* on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM
|
|
* element before it is removed.
|
|
*
|
|
* ### Methods
|
|
* - `controller(name)` - retrieves the controller of the current element or its parent. By default
|
|
* retrieves controller associated with the `ngController` directive. If `name` is provided as
|
|
* camelCase directive name, then the controller for this directive will be retrieved (e.g.
|
|
* `'ngModel'`).
|
|
* - `injector()` - retrieves the injector of the current element or its parent.
|
|
* - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current
|
|
* element or its parent.
|
|
* - `isolateScope()` - retrieves an isolate {@link api/ng.$rootScope.Scope scope} if one is attached directly to the
|
|
* current element. This getter should be used only on elements that contain a directive which starts a new isolate
|
|
* scope. Calling `scope()` on this element always returns the original non-isolate scope.
|
|
* - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
|
|
* parent element is reached.
|
|
*
|
|
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
|
|
* @returns {Object} jQuery object.

* # Injection Function Annotation
|
|
*
|
|
* JavaScript does not have annotations, and annotations are needed for dependency injection. The
|
|
* following are all valid ways of annotating function with injection arguments and are equivalent.
|
|
*
|
|
* <pre>
|
|
* // inferred (only works if code not minified/obfuscated)
|
|
* $injector.invoke(function(serviceA){});
|
|
*

|

* function explicit(serviceA) {};

* explicit.$inject = ['serviceA'];

* $injector.invoke(explicit);
|
|
*
|
|
* // inline
|
|
* $injector.invoke(['serviceA', function(serviceA){}]);
|
|
* </pre>
|
|
*
|
|
* ## Inference
|
|
*
|
|
* In JavaScript calling `toString()` on a function returns the function definition. The definition
|
|
* can then be parsed and the function arguments can be extracted. *NOTE:* This does not work with
|
|
* minification, and obfuscation tools since these tools change the argument names.
|
|
*
|
|
* ## `$inject` Annotation
|
|
* By adding a `$inject` property onto a function the injection parameters can be specified.
|
|
*
|
|
* ## Inline
|
|
* As an array of injection names, where the last item in the array is the function to call.

* dependencies.
|
|
*
|
|
* # Argument names
|
|
*
|
|
* The simplest form is to extract the dependencies from the arguments of the function. This is done
|
|
* by converting the function into a string using `toString()` method and extracting the argument
|
|
* names.
|
|
* <pre>

|
|
* </pre>
|
|
*
|
|
* This method does not work with code minification / obfuscation. For this reason the following
|
|
* annotation strategies are supported.
|
|
*
|
|
* # The `$inject` property
|
|
*
|
|
* If a function has an `$inject` property and its value is an array of strings, then the strings
|
|
* represent names of services to be injected into the function.
|
|
* <pre>
|
|
* // Given
|
|
* var MyController = function(obfuscatedScope, obfuscatedRoute) {
|
|
* // ...
|
|
* }
|
|
* // Define function dependencies
|
|
* MyController.$inject = ['$scope', '$route'];
|
|
*
|
|
* // Then
|
|
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
|
|
* </pre>
|
|
*
|
|
* # The array notation
|
|
*
|
|
* It is often desirable to inline Injected functions and that's when setting the `$inject` property
|
|
* is very inconvenient. In these situations using the array notation to specify the dependencies in
|
|
* a way that survives minification is a better choice:
|
|
*
|
|
* <pre>
|
|
* // We wish to write this (not minification / obfuscation safe)
|
|
* injector.invoke(function($compile, $rootScope) {
|
|
* // ...
|
|
* });
|
|
*
|
|
* // We are forced to write break inlining
|
|
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
|
|
* // ...
|
|
* };
|
|
* tmpFn.$inject = ['$compile', '$rootScope'];
|
|
* injector.invoke(tmpFn);
|
|
*
|
|
* // To better support inline function the inline annotation is supported
|
|
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
|
|
* // ...
|
|
* }]);
|
|
*
|
|
* // Therefore
|
|
* expect(injector.annotate(
|
|
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
|
|
* ).toEqual(['$compile', '$rootScope']);
|
|
* </pre>
|
|
*
|
|
* @param {function|Array.<string|Function>} fn Function for which dependent service names need to
|
|
* be retrieved as described above.

|
|
* The {@link AUTO.$provide $provide} service has a number of methods for registering components
|
|
* with the {@link AUTO.$injector $injector}. Many of these functions are also exposed on
|
|
* {@link angular.Module}.
|
|
*
|
|
* An Angular **service** is a singleton object created by a **service factory**. These **service
|
|
* factories** are functions which, in turn, are created by a **service provider**.
|
|
* The **service providers** are constructor functions. When instantiated they must contain a
|
|
* property called `$get`, which holds the **service factory** function.
|
|
*
|
|
* When you request a service, the {@link AUTO.$injector $injector} is responsible for finding the
|
|
* correct **service provider**, instantiating it and then calling its `$get` **service factory**
|
|
* function to get the instance of the **service**.
|
|
*
|
|
* Often services have no configuration options and there is no need to add methods to the service
|
|
* provider. The provider will be no more than a constructor function with a `$get` property. For
|
|
* these cases the {@link AUTO.$provide $provide} service has additional helper methods to register
|
|
* services without specifying a provider.
|
|
*
|
|
* * {@link AUTO.$provide#methods_provider provider(provider)} - registers a **service provider** with the
|
|
* {@link AUTO.$injector $injector}
|
|
* * {@link AUTO.$provide#methods_constant constant(obj)} - registers a value/object that can be accessed by
|
|
* providers and services.
|
|
* * {@link AUTO.$provide#methods_value value(obj)} - registers a value/object that can only be accessed by
|
|
* services, not providers.
|
|
* * {@link AUTO.$provide#methods_factory factory(fn)} - registers a service **factory function**, `fn`,
|
|
* that will be wrapped in a **service provider** object, whose `$get` property will contain the
|
|
* given factory function.
|
|
* * {@link AUTO.$provide#methods_service service(class)} - registers a **constructor function**, `class` that
|
|
* that will be wrapped in a **service provider** object, whose `$get` property will instantiate
|
|
* a new object using the given constructor function.
|
|
*
|
|
* See the individual methods for more information and examples.

|
|
* are constructor functions, whose instances are responsible for "providing" a factory for a
|
|
* service.
|
|
*
|
|
* Service provider names start with the name of the service they provide followed by `Provider`.
|
|
* For example, the {@link ng.$log $log} service has a provider called
|
|
* {@link ng.$logProvider $logProvider}.
|
|
*
|
|
* Service provider objects can have additional methods which allow configuration of the provider
|
|
* and its service. Importantly, you can configure what kind of service is created by the `$get`
|
|
* method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
|
|
* method {@link ng.$logProvider#debugEnabled debugEnabled}
|
|
* which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
|
|
* console or not.
|
|
*
|
|
* @param {string} name The name of the instance. NOTE: the provider will be available under `name +
|
|
'Provider'` key.
|
|
* @param {(Object|function())} provider If the provider is:
|
|
*
|
|
* - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
|
|
* {@link AUTO.$injector#invoke $injector.invoke()} when an instance needs to be
|
|
* created.
|
|
* - `Constructor`: a new instance of the provider will be created using
|

|

* @param {function()} decorator This function will be invoked when the service needs to be

* the {@link AUTO.$injector#invoke injector.invoke} method and is therefore fully injectable.
|

|

|
|
* ## Comprehensive Directive API
|
|
*
|
|
* There are many different options for a directive.
|
|
*
|
|
* The difference resides in the return value of the factory function.
|
|
* You can either return a "Directive Definition Object" (see below) that defines the directive properties,
|
|
* or just the `postLink` function (all other properties will have the default values).
|
|
*
|
|
* <div class="alert alert-success">
|
|
* **Best Practice:** It's recommended to use the "directive definition object" form.
|
|
* </div>
|
|
*
|
|
* Here's an example directive declared with a Directive Definition Object:
|
|
*
|
|
* <pre>
|
|
* var myModule = angular.module(...);
|
|
*
|
|
* myModule.directive('directiveName', function factory(injectables) {
|
|
* var directiveDefinitionObject = {
|
|
* priority: 0,
|
|
* template: '<div></div>', // or // function(tElement, tAttrs) { ... },
|
|
* // or
|
|
* // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
|
|
* replace: false,
|
|
* transclude: false,
|
|
* restrict: 'A',
|
|
* scope: false,
|
|
* controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
|
|
* require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
|
|
* compile: function compile(tElement, tAttrs, transclude) {
|
|
* return {
|
|
* pre: function preLink(scope, iElement, iAttrs, controller) { ... },
|
|
* post: function postLink(scope, iElement, iAttrs, controller) { ... }
|
|
* }
|
|
* // or
|
|
* // return function postLink( ... ) { ... }
|
|
* },
|
|
* // or
|
|
* // link: {
|
|
* // pre: function preLink(scope, iElement, iAttrs, controller) { ... },
|
|
* // post: function postLink(scope, iElement, iAttrs, controller) { ... }
|
|
* // }
|
|
* // or
|
|
* // link: function postLink( ... ) { ... }
|
|
* };
|
|
* return directiveDefinitionObject;
|
|
* });
|
|
* </pre>
|
|
*
|
|
* <div class="alert alert-warning">
|
|
* **Note:** Any unspecified options will use the default value. You can see the default values below.
|
|
* </div>
|
|
*
|
|
* Therefore the above can be simplified as:
|
|
*
|
|
* <pre>
|
|
* var myModule = angular.module(...);
|
|
*
|
|
* myModule.directive('directiveName', function factory(injectables) {
|
|
* var directiveDefinitionObject = {
|
|
* link: function postLink(scope, iElement, iAttrs) { ... }
|
|
* };
|
|
* return directiveDefinitionObject;
|
|
* // or
|
|
* // return function postLink(scope, iElement, iAttrs) { ... }
|
|
* });
|
|
* </pre>
|
|
*
|
|
*
|
|

|
|
* ### Directive Definition Object
|
|
*
|
|
* The directive definition object provides instructions to the {@link api/ng.$compile
|
|
* compiler}. The attributes are:
|
|
*
|
|
* #### `priority`
|
|
* When there are multiple directives defined on a single DOM element, sometimes it
|
|
* is necessary to specify the order in which the directives are applied. The `priority` is used
|
|
* to sort the directives before their `compile` functions get called. Priority is defined as a
|
|
* number. Directives with greater numerical `priority` are compiled first. The order of directives with
|
|
* the same priority is undefined. The default priority is `0`.
|
|
*
|
|
* #### `terminal`
|
|
* If set to true then the current `priority` will be the last set of directives
|
|
* which will execute (any directives at the current priority will still execute
|
|
* as the order of execution on same `priority` is undefined).
|
|
*
|
|
* #### `scope`
|
|
* **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the
|
|
* same element request a new scope, only one new scope is created. The new scope rule does not
|
|
* apply for the root of the template since the root of the template always gets a new scope.
|
|
*
|
|
* **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from
|
|
* normal scope in that it does not prototypically inherit from the parent scope. This is useful
|
|
* when creating reusable components, which should not accidentally read or modify data in the
|
|
* parent scope.
|
|
*
|
|
* The 'isolate' scope takes an object hash which defines a set of local scope properties
|
|
* derived from the parent scope. These local properties are useful for aliasing values for
|
|
* templates. Locals definition is a hash of local scope property to its source:
|
|
*
|
|
* * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
|
|
* always a string since DOM attributes are strings. If no `attr` name is specified then the
|
|
* attribute name is assumed to be the same as the local name.
|
|
* Given `<widget my-attr="hello {{name}}">` and widget definition
|
|
* of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect
|
|
* the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the
|
|
* `localName` property on the widget scope. The `name` is read from the parent scope (not
|
|
* component scope).
|
|
*
|
|
* * `=` or `=attr` - set up bi-directional binding between a local scope property and the
|
|
* parent scope property of name defined via the value of the `attr` attribute. If no `attr`
|
|
* name is specified then the attribute name is assumed to be the same as the local name.
|
|
* Given `<widget my-attr="parentModel">` and widget definition of
|
|
* `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the
|
|
* value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
|
|
* in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent
|
|
* scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You
|
|
* can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional.
|
|
*
|
|
* * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.
|
|
* If no `attr` name is specified then the attribute name is assumed to be the same as the
|
|
* local name. Given `<widget my-attr="count = count + value">` and widget definition of
|
|
* `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to
|
|
* a function wrapper for the `count = count + value` expression. Often it's desirable to
|
|
* pass data from the isolated scope via an expression and to the parent scope, this can be
|
|
* done by passing a map of local variable names and values into the expression wrapper fn.
|
|
* For example, if the expression is `increment(amount)` then we can specify the amount value
|
|
* by calling the `localFn` as `localFn({amount: 22})`.
|
|
*
|
|
*
|
|
*
|
|
* #### `controller`
|
|
* Controller constructor function. The controller is instantiated before the
|
|
* pre-linking phase and it is shared with other directives (see
|
|
* `require` attribute). This allows the directives to communicate with each other and augment
|
|
* each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
|
|
*
|
|
* * `$scope` - Current scope associated with the element
|
|
* * `$element` - Current element
|
|
* * `$attrs` - Current attributes object for the element
|
|
* * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
|
|
* `function(cloneLinkingFn)`.
|
|
*
|
|
*
|
|
* #### `require`
|
|
* Require another directive and inject its controller as the fourth argument to the linking function. The
|
|
* `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the
|
|
* injected argument will be an array in corresponding order. If no such directive can be
|
|
* found, or if the directive does not have a controller, then an error is raised. The name can be prefixed with:
|
|
*
|
|
* * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
|
|
* * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
|
|
* * `^` - Locate the required controller by searching the element's parents. Throw an error if not found.
|
|
* * `?^` - Attempt to locate the required controller by searching the element's parentsor pass `null` to the
|
|
* `link` fn if not found.
|
|
*
|
|
*
|
|
* #### `controllerAs`
|
|
* Controller alias at the directive scope. An alias for the controller so it
|
|
* can be referenced at the directive template. The directive needs to define a scope for this
|
|
* configuration to be used. Useful in the case when directive is used as component.
|
|
*
|
|
*
|
|
* #### `restrict`
|
|
* String of subset of `EACM` which restricts the directive to a specific directive
|
|
* declaration style. If omitted, the default (attributes only) is used.
|
|
*
|
|
* * `E` - Element name: `<my-directive></my-directive>`
|
|
* * `A` - Attribute (default): `<div my-directive="exp"></div>`
|
|
* * `C` - Class: `<div class="my-directive: exp;"></div>`
|
|
* * `M` - Comment: `<!-- directive: my-directive exp -->`
|
|
*
|
|
*
|
|
* #### `template`
|
|
* replace the current element with the contents of the HTML. The replacement process
|
|
* migrates all of the attributes / classes from the old element to the new one. See the
|
|
* {@link guide/directive#creating-custom-directives_creating-directives_template-expanding-directive
|
|
* Directives Guide} for an example.
|
|
*
|
|
* You can specify `template` as a string representing the template or as a function which takes
|
|
* two arguments `tElement` and `tAttrs` (described in the `compile` function api below) and
|
|
* returns a string value representing the template.
|
|
*
|
|
*
|
|
* #### `templateUrl`
|
|
* Same as `template` but the template is loaded from the specified URL. Because
|
|
* the template loading is asynchronous the compilation/linking is suspended until the template
|
|
* is loaded.
|
|
*
|
|
* You can specify `templateUrl` as a string representing the URL or as a function which takes two
|
|
* arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
|
|
* a string value representing the url. In either case, the template URL is passed through {@link
|
|
* api/ng.$sce#methods_getTrustedResourceUrl $sce.getTrustedResourceUrl}.
|
|
*
|
|
*
|
|
* #### `replace`
|
|
* specify where the template should be inserted. Defaults to `false`.
|
|
*
|
|
* * `true` - the template will replace the current element.
|
|
* * `false` - the template will replace the contents of the current element.
|
|
*
|
|
*
|
|
* #### `transclude`
|
|
* compile the content of the element and make it available to the directive.
|
|
* Typically used with {@link api/ng.directive:ngTransclude
|
|
* ngTransclude}. The advantage of transclusion is that the linking function receives a
|
|
* transclusion function which is pre-bound to the correct scope. In a typical setup the widget
|
|
* creates an `isolate` scope, but the transclusion is not a child, but a sibling of the `isolate`
|
|
* scope. This makes it possible for the widget to have private state, and the transclusion to
|
|
* be bound to the parent (pre-`isolate`) scope.
|
|
*
|
|
* * `true` - transclude the content of the directive.
|
|
* * `'element'` - transclude the whole element including any directives defined at lower priority.
|
|
*
|
|
*
|
|
* #### `compile`
|
|
*
|
|
* <pre>
|
|
* function compile(tElement, tAttrs, transclude) { ... }
|
|
* </pre>
|
|
*
|
|
* The compile function deals with transforming the template DOM. Since most directives do not do
|
|
* template transformation, it is not used often. Examples that require compile functions are
|
|
* directives that transform template DOM, such as {@link
|
|
* api/ng.directive:ngRepeat ngRepeat}, or load the contents
|
|
* asynchronously, such as {@link api/ngRoute.directive:ngView ngView}. The
|
|
* compile function takes the following arguments.
|
|
*
|
|
* * `tElement` - template element - The element where the directive has been declared. It is
|
|
* safe to do template transformation on the element and child elements only.
|
|
*
|
|
* * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
|
|
* between all directive compile functions.
|
|
*
|
|
* * `transclude` - A transclude linking function: `function(scope, cloneLinkingFn)`.
|
|
*
|
|
* <div class="alert alert-warning">
|
|
* **Note:** The template instance and the link instance may be different objects if the template has
|
|
* been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
|
|
* apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
|
|
* should be done in a linking function rather than in a compile function.
|
|
* </div>
|
|
*
|
|
* A compile function can have a return value which can be either a function or an object.
|
|
*
|
|
* * returning a (post-link) function - is equivalent to registering the linking function via the
|
|
* `link` property of the config object when the compile function is empty.
|
|
*
|
|
* * returning an object with function(s) registered via `pre` and `post` properties - allows you to

* control when a linking function should be called during the linking phase. See info about
|
|
* pre-linking and post-linking functions below.
|
|
*
|
|
*
|
|
* #### `link`
|
|
* This property is used only if the `compile` property is not defined.
|
|
*
|
|
* <pre>
|
|
* function link(scope, iElement, iAttrs, controller) { ... }
|
|
* </pre>
|
|
*
|
|
* The link function is responsible for registering DOM listeners as well as updating the DOM. It is
|
|
* executed after the template has been cloned. This is where most of the directive logic will be
|
|
* put.
|
|
*
|
|
* * `scope` - {@link api/ng.$rootScope.Scope Scope} - The scope to be used by the
|
|
* directive for registering {@link api/ng.$rootScope.Scope#methods_$watch watches}.
|
|
*
|
|
* * `iElement` - instance element - The element where the directive is to be used. It is safe to
|
|
* manipulate the children of the element only in `postLink` function since the children have
|
|
* already been linked.
|
|
*
|
|
* * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
|
|
* between all directive linking functions.
|
|
*
|
|
* * `controller` - a controller instance - A controller instance if at least one directive on the
|
|
* element defines a controller. The controller is shared among all the directives, which allows
|
|
* the directives to use the controllers as a communication channel.
|
|
*
|
|
*
|
|
*
|
|
* #### Pre-linking function
|
|
*
|
|
* Executed before the child elements are linked. Not safe to do DOM transformation since the
|
|
* compiler linking function will fail to locate the correct elements for linking.
|
|
*
|
|
* #### Post-linking function
|
|
*
|
|
* Executed after the child elements are linked. It is safe to do DOM transformation in the post-linking function.

|
|
* ### Attributes
|
|
*
|
|
* The {@link api/ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
|
|
* `link()` or `compile()` functions. It has a variety of uses.
|
|
*
|
|
* accessing *Normalized attribute names:*
|
|
* Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.
|
|
* the attributes object allows for normalized access to
|
|
* the attributes.
|
|
*
|
|
* * *Directive inter-communication:* All directives share the same instance of the attributes
|
|
* object which allows the directives to use the attributes object as inter directive
|
|
* communication.
|
|
*
|
|
* * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
|
|
* allowing other directives to read the interpolated value.
|
|
*
|
|
* * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
|
|
* that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
|
|
* the only way to easily get the actual value because during the linking phase the interpolation
|
|
* hasn't been evaluated yet and so the value is at this time set to `undefined`.
|
|
*
|
|
* <pre>
|
|
* function linkingFn(scope, elm, attrs, ctrl) {
|
|
* // get the attribute value
|
|
* console.log(attrs.ngModel);
|
|
*
|
|
* // change the attribute
|
|
* attrs.$set('ngModel', 'new value');
|
|
*
|
|
* // observe changes to interpolated attribute
|
|
* attrs.$observe('ngModel', function(value) {
|
|
* console.log('ngModel has changed value to ' + value);
|
|
* });
|
|
* }
|
|
* </pre>
|
|
*
|
|
* Below is an example using `$compileProvider`.
|
|
*
|
|
* <div class="alert alert-warning">
|
|
* **Note**: Typically directives are registered with `module.directive`. The example below is
|
|
* to illustrate how `$compile` works.
|

* </div>

|
|
* @param {number} maxPriority only apply directives lower then given priority (Only effects the
|
|
* root element(s), not their children)
|
|
* @returns {function(scope[, cloneAttachFn])} a link function which is used to bind template
|
|
* (a DOM element/tree) to a scope. Where:
|
|
*
|
|
* * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
|
|
* * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
|
|
* `template` and call the `cloneAttachFn` function allowing the caller to attach the
|
|
* cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
|
|
* called as: <br> `cloneAttachFn(clonedElement, scope)` where:
|
|
*
|
|
* * `clonedElement` - is a clone of the original `element` passed into the compiler.
|
|
* * `scope` - is the current scope with which the linking function is working with.
|
|
*
|
|
* Calling the linking function returns the element of the template. It is either the original
|
|
* element passed in, or the clone of the element if the `cloneAttachFn` is provided.
|
|
*
|
|
* After linking the view is not updated until after a call to $digest which typically is done by
|
|
* Angular automatically.
|
|
*
|
|
* If you need access to the bound view, there are two ways to do it:
|
|
*
|
|
* - If you are not asking the linking function to clone the template, create the DOM element(s)
|
|
* before you send them to the compiler and keep this reference around.
|
|
* <pre>
|
|
* var element = $compile('<p>{{total}}</p>')(scope);
|
|
* </pre>
|
|
*
|
|
* - if on the other hand, you need the element to be cloned, the view reference from the original
|
|
* example would not point to the clone, but rather to the original template that was cloned. In
|
|
* this case, you can access the clone via the cloneAttachFn:
|
|
* <pre>
|
|
* var templateHTML = angular.element('<p>{{total}}</p>'),
|
|
* scope = ....;
|
|
*
|
|
* var clonedElement = $compile(templateHTML)(scope, function(clonedElement, scope) {
|
|
* //attach the clone to DOM document at the right place
|
|
* });
|
|
*
|
|
* //now we have reference to the cloned DOM via `clone`
|
|
* </pre>
|
|
*
|
|
*
|
|
* For information on how the compiler works, see the
|
|
* {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

|
|
* The `$http` service is a core Angular service that facilitates communication with the remote
|
|
* HTTP servers via the browser's {@link https://developer.mozilla.org/en/xmlhttprequest
|
|
* XMLHttpRequest} object or via {@link http://en.wikipedia.org/wiki/JSONP JSONP}.
|
|
*
|
|
* For unit testing applications that use `$http` service, see
|
|
* {@link ngMock.$httpBackend $httpBackend mock}.
|
|
*
|
|
* For a higher level of abstraction, please check out the {@link ngResource.$resource
|
|
* $resource} service.
|
|
*
|
|
* The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
|
|
* the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
|
|
* it is important to familiarize yourself with these APIs and the guarantees they provide.
|
|
*
|
|
*
|
|
* # General usage
|
|
* The `$http` service is a function which takes a single argument — a configuration object —
|
|
* that is used to generate an HTTP request and returns a {@link ng.$q promise}
|
|
* with two $http specific methods: `success` and `error`.
|
|
*
|
|
* <pre>
|
|
* $http({method: 'GET', url: '/someUrl'}).
|
|
* success(function(data, status, headers, config) {
|
|
* // this callback will be called asynchronously
|
|
* // when the response is available
|
|
* }).
|
|
* error(function(data, status, headers, config) {
|
|
* // called asynchronously if an error occurs
|
|
* // or server returns response with an error status.
|
|
* });
|
|
* </pre>
|
|
*
|
|
* Since the returned value of calling the $http function is a `promise`, you can also use
|
|
* the `then` method to register callbacks, and these callbacks will receive a single argument –
|
|
* an object representing the response. See the API signature and type info below for more
|
|
* details.
|
|
*
|
|
* A response status code between 200 and 299 is considered a success status and
|
|
* will result in the success callback being called. Note that if the response is a redirect,
|
|
* XMLHttpRequest will transparently follow it, meaning that the error callback will not be
|
|
* called for such responses.
|
|
*
|
|
* # Calling $http from outside AngularJS
|
|
* The `$http` service will not actually send the request until the next `$digest()` is
|
|
* executed. Normally this is not an issue, since almost all the time your call to `$http` will
|
|
* be from within a `$apply()` block.
|
|
* If you are calling `$http` from outside Angular, then you should wrap it in a call to
|
|
* `$apply` to cause a $digest to occur and also to handle errors in the block correctly.
|
|
*
|
|
* ```
|
|
* $scope.$apply(function() {
|
|
* $http(...);
|
|
* });
|
|
* ```
|
|
*
|
|
* # Writing Unit Tests that use $http
|
|
* When unit testing you are mostly responsible for scheduling the `$digest` cycle. If you do
|
|
* not trigger a `$digest` before calling `$httpBackend.flush()` then the request will not have
|
|
* been made and `$httpBackend.expect(...)` expectations will fail. The solution is to run the
|
|
* code that calls the `$http()` method inside a $apply block as explained in the previous
|
|
* section.
|
|
*
|
|
* ```
|
|
* $httpBackend.expectGET(...);
|
|
* $scope.$apply(function() {
|
|
* $http.get(...);
|
|
* });
|
|
* $httpBackend.flush();
|
|
* ```
|
|
*
|
|
* # Shortcut methods
|
|
*
|
|
* Since all invocations of the $http service require passing in an HTTP method and URL, and
|
|
* POST/PUT requests require request data to be provided as well, shortcut methods
|
|
* were created:
|
|
*
|
|
* <pre>
|
|
* $http.get('/someUrl').success(successCallback);
|
|
* $http.post('/someUrl', data).success(successCallback);
|
|
* </pre>
|
|
*
|
|
* Complete list of shortcut methods:
|
|
*
|
|
* - {@link ng.$http#methods_get $http.get}
|
|
* - {@link ng.$http#methods_head $http.head}
|
|
* - {@link ng.$http#methods_post $http.post}
|
|
* - {@link ng.$http#methods_put $http.put}
|
|
* - {@link ng.$http#methods_delete $http.delete}
|
|
* - {@link ng.$http#methods_jsonp $http.jsonp}
|
|
*
|
|
*
|
|
* # Setting HTTP Headers
|
|
*
|
|
* The $http service will automatically add certain HTTP headers to all requests. These defaults
|
|
* can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
|
|
* object, which currently contains this default configuration:
|
|
*
|
|
* - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
|
|
* - `Accept: application/json, text/plain, * / *`
|
|
* - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
|
|
* - `Content-Type: application/json`
|
|
* - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
|
|
* - `Content-Type: application/json`
|
|
*
|
|
* To add or overwrite these defaults, simply add or remove a property from these configuration
|
|
* objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
|
|
* with the lowercased HTTP method name as the key, e.g.
|
|
* `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }.
|
|
*
|
|
* The defaults can also be set at runtime via the `$http.defaults` object in the same
|
|
* fashion. In addition, you can supply a `headers` property in the config object passed when
|
|
* calling `$http(config)`, which overrides the defaults without changing them globally.
|
|
*
|
|
*
|
|
* # Transforming Requests and Responses
|
|
*
|
|
* Both requests and responses can be transformed using transform functions. By default, Angular
|
|
* applies these transformations:
|
|
*
|
|
* Request transformations:
|
|
*
|
|
* - If the `data` property of the request configuration object contains an object, serialize it
|
|
* into JSON format.
|
|
*
|
|
* Response transformations:
|
|
*
|
|
* - If XSRF prefix is detected, strip it (see Security Considerations section below).
|
|
* - If JSON response is detected, deserialize it using a JSON parser.
|
|
*
|
|
* To globally augment or override the default transforms, modify the
|
|
* `$httpProvider.defaults.transformRequest` and `$httpProvider.defaults.transformResponse`
|
|
* properties. These properties are by default an array of transform functions, which allows you
|
|
* to `push` or `unshift` a new transformation function into the transformation chain. You can
|
|
* also decide to completely override any default transformations by assigning your
|
|
* transformation functions to these properties directly without the array wrapper.
|
|
*
|
|
* Similarly, to locally override the request/response transforms, augment the
|
|
* `transformRequest` and/or `transformResponse` properties of the configuration object passed
|
|
* into `$http`.
|
|
*
|
|
*
|
|
* # Caching
|
|
*
|
|
* To enable caching, set the configuration property `cache` to `true`. When the cache is
|
|
* enabled, `$http` stores the response from the server in local cache. Next time the
|
|
* response is served from the cache without sending a request to the server.
|
|
*
|
|
* Note that even if the response is served from cache, delivery of the data is asynchronous in
|
|
* the same way that real requests are.
|
|
*
|
|
* If there are multiple GET requests for the same URL that should be cached using the same
|
|
* cache, but the cache is not populated yet, only one request to the server will be made and
|
|
* the remaining requests will be fulfilled using the response from the first request.
|
|
*
|
|
* A custom default cache built with $cacheFactory can be provided in $http.defaults.cache.
|
|
* To skip it, set configuration property `cache` to `false`.
|
|
*
|
|
*
|
|
* # Interceptors
|
|
*
|
|
* Before you start creating interceptors, be sure to understand the
|
|
* {@link ng.$q $q and deferred/promise APIs}.
|
|
*
|
|
* For purposes of global error handling, authentication, or any kind of synchronous or
|
|
* asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
|
|
* able to intercept requests before they are handed to the server and
|
|
* responses before they are handed over to the application code that
|
|
* initiated these requests. The interceptors leverage the {@link ng.$q
|
|
* promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
|
|
*
|
|
* The interceptors are service factories that are registered with the `$httpProvider` by
|
|
* adding them to the `$httpProvider.interceptors` array. The factory is called and
|
|
* injected with dependencies (if specified) and returns the interceptor.
|
|
*
|
|
* There are two kinds of interceptors (and two kinds of rejection interceptors):
|
|
*
|
|
* * `request`: interceptors get called with http `config` object. The function is free to
|
|
* modify the `config` or create a new one. The function needs to return the `config`
|
|
* directly or as a promise.
|
|
* * `requestError`: interceptor gets called when a previous interceptor threw an error or
|
|
* resolved with a rejection.
|
|
* * `response`: interceptors get called with http `response` object. The function is free to
|
|
* modify the `response` or create a new one. The function needs to return the `response`
|
|
* directly or as a promise.
|
|
* * `responseError`: interceptor gets called when a previous interceptor threw an error or
|
|
* resolved with a rejection.
|
|
*
|
|
*
|
|
* <pre>
|
|
* // register the interceptor as a service
|
|
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {

* # Security Considerations
|
|
*
|
|
* When designing web applications, consider security threats from:
|
|
*
|
|
* - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
|
|
* JSON vulnerability}
|
|
* - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}
|
|
*
|
|
* Both server and the client must cooperate in order to eliminate these threats. Angular comes
|
|
* pre-configured with strategies that address these issues, but for this to work backend server
|
|
* cooperation is required.
|
|
*
|
|
* ## JSON Vulnerability Protection
|
|
*
|
|
* A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
|
|
* JSON vulnerability} allows third party website to turn your JSON resource URL into
|
|
* {@link http://en.wikipedia.org/wiki/JSONP JSONP} request under some conditions. To
|
|
* counter this your server can prefix all JSON requests with following string `")]}',\n"`.
|
|
* Angular will automatically strip the prefix before processing it as JSON.
|
|
*
|
|
* For example if your server needs to return:
|
|
* <pre>
|
|
* ['one','two']
|
|
* </pre>
|
|
*
|
|
* which is vulnerable to attack, your server can return:
|
|
* <pre>
|
|
* )]}',
|
|
* ['one','two']
|
|
* </pre>
|
|
*
|
|
* Angular will strip the prefix, before processing the JSON.
|
|
*
|
|
*
|
|
* ## Cross Site Request Forgery (XSRF) Protection
|
|
*
|
|
* {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which
|
|
* an unauthorized site can gain your user's private data. Angular provides a mechanism
|
|
* to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
|
|
* (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only
|
|
* JavaScript that runs on your domain could read the cookie, your server can be assured that
|
|
* the XHR came from JavaScript running on your domain. The header will not be set for
|
|
* cross-domain requests.
|
|
*
|
|
* To take advantage of this, your server needs to set a token in a JavaScript readable session
|
|
* cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
|
|
* server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
|
|
* that only JavaScript running on your domain could have sent the request. The token must be
|
|
* unique for each user and must be verifiable by the server (to prevent the JavaScript from
|
|
* making up its own tokens). We recommend that the token is a digest of your site's
|
|
* authentication cookie with a {@link https://en.wikipedia.org/wiki/Salt_(cryptography) salt}
|
|
* for added security.
|
|
*
|
|
* The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
|
|
* properties of either $httpProvider.defaults, or the per-request config object.
|
|
*
|
|
*
|
|
* @param {object} config Object describing the request to be made and how it should be
|
|
* processed. The object has following properties:
|
|
*
|
|
* - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
|
|
* - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
|
|
* - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned
|
|
* to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be
|
|
* JSONified.
|
|
* - **data** – `{string|Object}` – Data to be sent as the request message data.
|
|
* - **headers** – `{Object}` – Map of strings or functions which return strings representing
|
|
* HTTP headers to send to the server. If the return value of a function is null, the
|
|
* header will not be sent.
|
|
* - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
|
|
* - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
|
|
* - **transformRequest** –
|
|
* `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
|
|
* transform function or an array of such functions. The transform function takes the http
|
|
* request body and headers and returns its transformed (typically serialized) version.
|
|
* - **transformResponse** –
|
|
* `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
|
|
* transform function or an array of such functions. The transform function takes the http
|
|
* response body and headers and returns its transformed (typically deserialized) version.
|
|
* - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
|
|
* GET request, otherwise if a cache instance built with
|
|
* {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
|
|
* caching.
|
|
* - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
|
|
* that should abort the request when resolved.
|
|
* - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the
|
|
* XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
|
|
* requests with credentials} for more information.
|
|
* - **responseType** - `{string}` - see {@link
|
|
* https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}.
|
|
*
|
|
* @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
|
|
* standard `then` method and two http specific methods: `success` and `error`. The `then`
|
|
* method takes two arguments a success and an error callback which will be called with a
|
|
* response object. The `success` and `error` methods take a single argument - a function that
|
|
* will be called when the request succeeds or fails respectively. The arguments passed into
|
|
* these functions are destructured representation of the response object passed into the
|
|
* `then` method. The response object has these properties:
|
|
*
|
|
* - **data** – `{string|Object}` – The response body transformed with the transform
|
|
* functions.
|
|
* - **status** – `{number}` – HTTP status code of the response.
|
|
* - **headers** – `{function([headerName])}` – Header getter function.
|
|
* - **config** – `{Object}` – The configuration object that was used to generate the request.
|
|
*
|
|
* @property {Array.<Object>} pendingRequests Array of config objects for currently pending
|
|
* requests. This is primarily meant to be used for debugging purposes.

// Sandboxing Angular Expressions
|
|
// ------------------------------
|
|
// Angular expressions are generally considered safe because these expressions only have direct
|
|
// access to $scope and locals. However, one can obtain the ability to execute arbitrary JS code by
|
|
// obtaining a reference to native JS functions such as the Function constructor, the global Window
|
|
// or Document object. In addition, many powerful functions for use by JavaScript code are
|
|
// published on scope that shouldn't be available from within an Angular expression.
|
|
//
|
|
// As an example, consider the following Angular expression:
|
|
//
|
|
// {}.toString.constructor(alert("evil JS code"))
|
|
//
|
|
// We want to prevent this type of access. For the sake of performance, during the lexing phase we
|
|
// disallow any "dotted" access to any member named "constructor" or to any member whose name begins
|
|
// or ends with an underscore. The latter allows one to exclude the private / JavaScript only API
|
|
// available on the scope and controllers from the context of an Angular expression.
|
|
//
|
|
// For reflective calls (a[b]), we check that the value of the lookup is not the Function
|
|
// constructor, Window or DOM node while evaluating the expression, which is a stronger but more
|
|
// expensive test. Since reflective calls are expensive anyway, this is not such a big deal compared
|
|
// to static dereferencing.
|
|
//
|
|
// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
|
|
// against the expression language, but not to prevent exploits that were enabled by exposing
|
|
// sensitive JavaScript or browser apis on Scope. Exposing such objects on a Scope is never a good
|
|
// practice and therefore we are not even trying to protect against interaction with an object
|
|
// explicitly exposed in this way.
|
|
//
|
|
// A developer could foil the name check by aliasing the Function constructor under a different
|
|
// name on the scope.
|
|
//
|
|
// In general, it is not possible to access a Window object from an angular expression unless a
|
|
// window or some DOM object that has a reference to window is published onto a Scope.

* @description
|
|
*
|
|
* **This feature is deprecated, see deprecation notes below for more info**
|
|
*
|
|
* If set to true (default is false), $parse will unwrap promises automatically when a promise is
|
|
* found at any part of the expression. In other words, if set to true, the expression will always
|
|
* result in a non-promise value.
|
|
*
|
|
* While the promise is unresolved, it's treated as undefined, but once resolved and fulfilled,
|
|
* the fulfillment value is used in place of the promise while evaluating the expression.
|
|
*
|
|
* **Deprecation notice**
|
|
*
|
|
* This is a feature that didn't prove to be wildly useful or popular, primarily because of the
|
|
* dichotomy between data access in templates (accessed as raw values) and controller code
|
|
* (accessed as promises).
|
|
*
|
|
* In most code we ended up resolving promises manually in controllers anyway and thus unifying
|
|
* the model access there.
|
|
*
|
|
* Other downsides of automatic promise unwrapping:
|
|
*
|
|
* - when building components it's often desirable to receive the raw promises
|
|
* - adds complexity and slows down expression evaluation
|
|
* - makes expression code pre-generation unattractive due to the amount of code that needs to be
|
|
* generated
|
|
* - makes IDE auto-completion and tool support hard
|
|
*
|
|
* **Warning Logs**
|
|
*
|
|
* If the unwrapping is enabled, Angular will log a warning about each expression that unwraps a
|
|
* promise (to reduce the noise, each expression is logged only once). To disable this logging use
|
|
* `$parseProvider.logPromiseWarnings(false)` api.
|
|
*
|
|
*
|
|
* @param {boolean=} value New value.
|
|
* @returns {boolean|self} Returns the current setting when used as getter and self if used as
|
|
* setter.

|
|
* @description
|
|
* A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
|
|
*
|
|
* [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
|
|
* interface for interacting with an object that represents the result of an action that is
|
|
* performed asynchronously, and may or may not be finished at any given point in time.
|
|
*
|
|
* From the perspective of dealing with error handling, deferred and promise APIs are to
|
|
* asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
|
|
*
|
|
* <pre>
|
|
* // for the purpose of this example let's assume that variables `$q` and `scope` are
|
|
* // available in the current lexical scope (they could have been injected or passed in).
|
|
*
|
|
* function asyncGreet(name) {
|
|
* var deferred = $q.defer();
|
|
*
|
|
* setTimeout(function() {
|
|
* // since this fn executes async in a future turn of the event loop, we need to wrap
|
|
* // our code into an $apply call so that the model changes are properly observed.
|
|
* scope.$apply(function() {
|
|
* deferred.notify('About to greet ' + name + '.');
|
|
*
|
|
* if (okToGreet(name)) {
|
|
* deferred.resolve('Hello, ' + name + '!');
|
|
* } else {
|
|
* deferred.reject('Greeting ' + name + ' is not allowed.');
|
|
* }
|
|
* });
|
|
* }, 1000);
|
|
*
|
|
* return deferred.promise;
|
|
* }
|
|
*
|
|
* var promise = asyncGreet('Robin Hood');
|
|
* promise.then(function(greeting) {
|
|
* alert('Success: ' + greeting);
|
|
* }, function(reason) {
|
|
* alert('Failed: ' + reason);
|
|
* }, function(update) {
|
|
* alert('Got notification: ' + update);
|
|
* });
|
|
* </pre>
|
|
*
|
|
* At first it might not be obvious why this extra complexity is worth the trouble. The payoff
|
|
* comes in the way of guarantees that promise and deferred APIs make, see
|
|
* https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
|
|
*
|
|
* Additionally the promise api allows for composition that is very hard to do with the
|
|
* traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
|
|
* For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
|
|
* section on serial or parallel joining of promises.

|
* # The Deferred API
|
|
*
|
|
* A new instance of deferred is constructed by calling `$q.defer()`.
|
|
*
|
|
* The purpose of the deferred object is to expose the associated Promise instance as well as APIs
|
|
* that can be used for signaling the successful or unsuccessful completion, as well as the status
|
|
* of the task.
|
|
*
|
|
* **Methods**
|
|
*
|
|
* - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
|
|
* constructed via `$q.reject`, the promise will be rejected instead.
|
|
* - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
|
|
* resolving it with a rejection constructed via `$q.reject`.
|
|
* - `notify(value)` - provides updates on the status of the promises execution. This may be called
|
|
* multiple times before the promise is either resolved or rejected.
|
|
*
|
|
* **Properties**
|
|
*
|
|
* - promise – `{Promise}` – promise object associated with this deferred.
|
|
*
|
|
*
|
|
* # The Promise API
|
|
*
|
|
* A new promise instance is created when a deferred instance is created and can be retrieved by
|
|
* calling `deferred.promise`.
|
|
*
|
|
* The purpose of the promise object is to allow for interested parties to get access to the result
|
|
* of the deferred task when it completes.
|
|
*
|
|
* **Methods**
|
|
*
|
|
* - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or
|
|
* will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
|
|
* as soon as the result is available. The callbacks are called with a single argument: the result
|
|
* or rejection reason. Additionally, the notify callback may be called zero or more times to
|
|
* provide a progress indication, before the promise is resolved or rejected.
|
|
*
|
|
* This method *returns a new promise* which is resolved or rejected via the return value of the
|
|
* `successCallback`, `errorCallback`. It also notifies via the return value of the
|
|
* `notifyCallback` method. The promise can not be resolved or rejected from the notifyCallback
|
|
* method.
|
|
*
|
|
* - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
|
|
*
|
|
* - `finally(callback)` – allows you to observe either the fulfillment or rejection of a promise,
|
|
* but to do so without modifying the final value. This is useful to release resources or do some
|
|
* clean-up that needs to be done whether the promise was rejected or resolved. See the [full
|
|
* specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
|
|
* more information.
|
|
*
|
|
* Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as
|
|
* property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to
|
|
* make your code IE8 compatible.
|
|
*
|
|
* # Chaining promises
|
|
*
|
|
* Because calling the `then` method of a promise returns a new derived promise, it is easily
|
|
* possible to create a chain of promises:
|
|
*
|
|
* <pre>
|
|
* promiseB = promiseA.then(function(result) {
|
|
* return result + 1;
|
|
* });
|
|
*
|
|
* // promiseB will be resolved immediately after promiseA is resolved and its value
|
|
* // will be the result of promiseA incremented by 1
|
|
* </pre>
|
|
*
|
|
* It is possible to create chains of any length and since a promise can be resolved with another
|
|
* promise (which will defer its resolution further), it is possible to pause/defer resolution of
|
|
* the promises at any point in the chain. This makes it possible to implement powerful APIs like
|
|
* $http's response interceptors.
|
|
*
|
|
*
|
|
* # Differences between Kris Kowal's Q and $q
|
|
*
|
|
* There are three main differences:
|
|
*
|
|
* - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
|
|
* mechanism in angular, which means faster propagation of resolution or rejection into your
|
|
* models and avoiding unnecessary browser repaints, which would result in flickering UI.
|
|
* - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
|
|
* all the important functionality needed for common async tasks.
|
|
*
|
|
* # Testing
|
|
*
|
|
* <pre>
|
|
* it('should simulate promise', inject(function($q, $rootScope) {
|
|
* var deferred = $q.defer();
|
|
* var promise = deferred.promise;
|
|
* var resolvedValue;
|
|
*
|
|
* promise.then(function(value) { resolvedValue = value; });
|
|
* expect(resolvedValue).toBeUndefined();
|
|
*
|
|
* // Simulate resolving of promise
|
|
* deferred.resolve(123);
|
|
* // Note that the 'then' function does not get called synchronously.
|
|
* // This is because we want the promise API to always be async, whether or not
|
|
* // it got called synchronously or asynchronously.
|
|
* expect(resolvedValue).toBeUndefined();
|
|
*
|
|
* // Propagate promise resolution to 'then' functions using $apply().
|
|
* $rootScope.$apply();
|
|
* expect(resolvedValue).toEqual(123);
|
|
* });
|
|
* </pre>

* The design decisions behind the scope are heavily favored for speed and memory consumption.
|
|
*
|
|
* The typical use of scope is to watch the expressions, which most of the time return the same
|
|
* value as last time so we optimize the operation.
|
|
*
|
|
* Closures construction is expensive in terms of speed as well as memory:
|
|
* - No closures, instead use prototypical inheritance for API
|
|
* - Internal state needs to be stored on scope directly, which means that private state is
|
|
* exposed as $$____ properties
|
|
*
|
|
* Loop operations are optimized by using while(count--) { ... }
|
|
* - this means that in order to keep the same order of execution as addition we have to add
|
|
* items to the array at the beginning (shift) instead of at the end (push)
|
|
*
|
|
* Child scopes are created and removed often
|
|
* - Using an array would be slow since inserts in middle are expensive so we use linked list
|
|
*
|
|
* There are few watches then a lot of observers. This is why you don't want the observer to be
|
|
* implemented in the same way as watch. Watch requires return of initialization function which
|
|
* are expensive to construct.

|
|
* Registers a `listener` callback to be executed whenever the `watchExpression` changes.
|
|
*
|
|
* - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
|
|
* $digest()} and should return the value that will be watched. (Since
|
|
* {@link ng.$rootScope.Scope#$digest $digest()} reruns when it detects changes the
|
|
* `watchExpression` can execute multiple times per
|
|
* {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
|
|
* - The `listener` is called only when the value from the current `watchExpression` and the
|
|
* previous call to `watchExpression` are not equal (with the exception of the initial run,
|
|
* see below). The inequality is determined according to
|
|
* {@link angular.equals} function. To save the value of the object for later comparison,
|
|
* the {@link angular.copy} function is used. It also means that watching complex options
|
|
* will have adverse memory and performance implications.
|
|
* - The watch `listener` may change the model, which may trigger other `listener`s to fire.
|
|
* This is achieved by rerunning the watchers until no changes are detected. The rerun
|
|
* iteration limit is 10 to prevent an infinite loop deadlock.
|
|
*
|
|
*
|
|
* If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
|
|
* you can register a `watchExpression` function with no `listener`. (Since `watchExpression`
|
|
* can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a
|
|
* change is detected, be prepared for multiple calls to your listener.)
|
|
*
|
|
* After a watcher is registered with the scope, the `listener` fn is called asynchronously
|
|
* (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
|
|
* watcher. In rare cases, this is undesirable because the listener is called when the result
|
|
* of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
|
|
* can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
|
|
* listener was called due to initialization.
|
|
*
|
|
* The example below contains an illustration of using a function as your $watch listener

* Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and

|
* the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}

|
* loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of

* iterations exceeds 10.
|
|
*
|
|
* Usually, you don't call `$digest()` directly in

|
* {@link ng.directive:ngController controllers} or in

* Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within

|
|
*
|
|
* If you want to be notified whenever `$digest()` is called,

|
* you can register a `watchExpression` function with
|

* {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.

|
|
* `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
|
|
* Contextual Escaping (SCE)} services to AngularJS.
|
|
*
|
|
* Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
|
|
* the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS. This is
|
|
* because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
|
|
* override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
|
|
* work because `$sce` delegates to `$sceDelegate` for these operations.
|
|
*
|
|
* Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
|
|
*
|
|
* The default instance of `$sceDelegate` should work out of the box with little pain. While you
|
|
* can override it completely to change the behavior of `$sce`, the common case would
|
|
* involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
|
|
* your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
|
|
* templates. Refer {@link ng.$sceDelegateProvider#methods_resourceUrlWhitelist
|
|
* $sceDelegateProvider.resourceUrlWhitelist} and {@link

|
* The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate

* $sceDelegate} service. This allows one to get/set the whitelists and blacklists used to ensure
|
|
* that the URLs used for sourcing Angular templates are safe. Refer {@link

* For the general details about this service in Angular, read the main page for {@link ng.$sce

* Strict Contextual Escaping (SCE)}.
|
|
*
|
|
* **Example**: Consider the following case. <a name="example"></a>
|
|
*
|
|
* - your app is hosted at url `http://myapp.example.com/`
|
|
* - but some of your templates are hosted on other domains you control such as
|
|
* `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
|
|
* - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
|
|
*
|
|
* Here is what a secure configuration for this scenario might look like:
|
|
*
|

|
|
* 'self',
|
|
* // Allow loading from our assets domain. Notice the difference between * and **.
|

|
|
* # Strict Contextual Escaping
|
|
*
|
|
* Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
|
|
* contexts to result in a value that is marked as safe to use for that context. One example of
|
|
* such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer
|
|
* to these contexts as privileged or SCE contexts.
|
|
*
|
|
* As of version 1.2, Angular ships with SCE enabled by default.
|
|
*
|
|
* Note: When enabled (the default), IE8 in quirks mode is not supported. In this mode, IE8 allows
|
|
* one to execute arbitrary javascript by the use of the expression() syntax. Refer
|
|
* <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
|
|
* You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
|
|
* to the top of your HTML document.
|
|
*
|
|
* SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
|
|
* security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
|
|
*
|
|
* Here's an example of a binding in a privileged context:
|
|
*
|
|
* <pre class="prettyprint">
|
|
* <input ng-model="userHtml">
|
|
* <div ng-bind-html="{{userHtml}}">
|
|
* </pre>
|
|
*
|
|
* Notice that `ng-bind-html` is bound to `{{userHtml}}` controlled by the user. With SCE
|
|
* disabled, this application allows the user to render arbitrary HTML into the DIV.
|
|
* In a more realistic example, one may be rendering user comments, blog articles, etc. via
|
|
* bindings. (HTML is just one example of a context where rendering user controlled input creates
|
|
* security vulnerabilities.)
|
|
*
|
|
* For the case of HTML, you might use a library, either on the client side, or on the server side,
|
|
* to sanitize unsafe HTML before binding to the value and rendering it in the document.
|
|
*
|
|
* How would you ensure that every place that used these types of bindings was bound to a value that
|
|
* was sanitized by your library (or returned as safe for rendering by your server?) How can you
|
|
* ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
|
|
* properties/fields and forgot to update the binding to the sanitized value?
|
|
*
|
|
* To be secure by default, you want to ensure that any such bindings are disallowed unless you can
|
|
* determine that something explicitly says it's safe to use a value for binding in that
|
|
* context. You can then audit your code (a simple grep would do) to ensure that this is only done
|
|
* for those values that you can easily tell are safe - because they were received from your server,
|
|
* sanitized by your library, etc. You can organize your codebase to help with this - perhaps
|
|
* allowing only the files in a specific directory to do this. Ensuring that the internal API
|
|
* exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
|
|
*
|
|
* In the case of AngularJS' SCE service, one uses {@link ng.$sce#methods_trustAs $sce.trustAs}
|
|
* (and shorthand methods such as {@link ng.$sce#methods_trustAsHtml $sce.trustAsHtml}, etc.) to
|
|
* obtain values that will be accepted by SCE / privileged contexts.
|
|
*
|
|
*
|
|
* ## How does it work?
|
|
*
|
|
* In privileged contexts, directives and code will bind to the result of {@link ng.$sce#methods_getTrusted
|
|
* $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link
|
|
* ng.$sce#methods_parse $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
|
|
* {@link ng.$sce#methods_getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
|
|
*
|
|
* As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
|
|
* ng.$sce#methods_parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
|
|
* simplified):
|
|
*
|
|
* <pre class="prettyprint">
|
|
* var ngBindHtmlDirective = ['$sce', function($sce) {
|
|
* return function(scope, element, attr) {
|
|
* scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
|
|
* element.html(value || '');
|
|
* });
|
|
* };
|
|
* }];
|
|
* </pre>
|
|
*
|
|
* ## Impact on loading templates
|
|
*
|
|
* This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
|
|
* `templateUrl`'s specified by {@link guide/directive directives}.
|
|
*
|
|
* By default, Angular only loads templates from the same domain and protocol as the application
|
|
* document. This is done by calling {@link ng.$sce#methods_getTrustedResourceUrl
|
|
* $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
|
|
* protocols, you may either either {@link ng.$sceDelegateProvider#methods_resourceUrlWhitelist whitelist
|
|
* them} or {@link ng.$sce#methods_trustAsResourceUrl wrap it} into a trusted value.
|
|
*
|
|
* *Please note*:
|
|
* The browser's
|
|
* {@link https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest
|
|
* Same Origin Policy} and {@link http://www.w3.org/TR/cors/ Cross-Origin Resource Sharing (CORS)}
|
|
* policy apply in addition to this and may further restrict whether the template is successfully
|
|
* loaded. This means that without the right CORS policy, loading templates from a different domain
|
|
* won't work on all browsers. Also, loading templates from `file://` URL does not work on some
|
|
* browsers.
|
|
*

* ## This feels like too much overhead for the developer?
|
|
*
|
|
* It's important to remember that SCE only applies to interpolation expressions.
|
|
*
|
|
* If your expressions are constant literals, they're automatically trusted and you don't need to
|
|
* call `$sce.trustAs` on them. (e.g.
|
|
* `<div ng-html-bind-unsafe="'<b>implicitly trusted</b>'"></div>`) just works.
|
|
*
|
|
* Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
|
|
* through {@link ng.$sce#methods_getTrusted $sce.getTrusted}. SCE doesn't play a role here.
|
|
*
|
|
* The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
|
|
* templates in `ng-include` from your application's domain without having to even know about SCE.
|
|
* It blocks loading templates from other domains or loading templates over http from an https
|
|
* served document. You can change these by setting your own custom {@link
|
|
* ng.$sceDelegateProvider#methods_resourceUrlWhitelist whitelists} and {@link
|
|
* ng.$sceDelegateProvider#methods_resourceUrlBlacklist blacklists} for matching such URLs.
|
|
*
|
|
* This significantly reduces the overhead. It is far easier to pay the small overhead and have an
|
|
* application that's secure and can be audited to verify that with much more ease than bolting
|
|
* security onto an application later.

|
|
* ## What trusted context types are supported?
|
|
*
|
|
* | Context | Notes |
|
|
* |---------------------|----------------|
|
|
* | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. |
|
|
* | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |
|
|
* | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`<a href=` and `<img src=` sanitize their urls and don't consititute an SCE context. |
|
|
* | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contens are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.) <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
|
|
* | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. |
|
|
*
|
|
* ## Format of items in {@link ng.$sceDelegateProvider#methods_resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#methods_resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
|
|
*
|
|
* Each element in these arrays must be one of the following:
|
|
*
|
|
* - **'self'**
|
|
* - The special **string**, `'self'`, can be used to match against all URLs of the **same
|
|
* domain** as the application document using the **same protocol**.
|
|
* - **String** (except the special value `'self'`)
|
|
* - The string is matched against the full *normalized / absolute URL* of the resource
|
|
* being tested (substring matches are not good enough.)
|
|
* - There are exactly **two wildcard sequences** - `*` and `**`. All other characters
|
|
* match themselves.
|
|
* - `*`: matches zero or more occurances of any character other than one of the following 6
|
|
* characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'. It's a useful wildcard for use
|
|
* in a whitelist.
|
|
* - `**`: matches zero or more occurances of *any* character. As such, it's not
|
|
* not appropriate to use in for a scheme, domain, etc. as it would match too much. (e.g.
|
|
* http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
|
|
* not have been the intention.) It's usage at the very end of the path is ok. (e.g.
|
|
* http://foo.example.com/templates/**).
|
|
* - **RegExp** (*see caveat below*)
|
|
* - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax
|
|
* (and all the inevitable escaping) makes them *harder to maintain*. It's easy to
|
|
* accidentally introduce a bug when one updates a complex expression (imho, all regexes should
|
|
* have good test coverage.). For instance, the use of `.` in the regex is correct only in a
|
|
* small number of cases. A `.` character in the regex used when matching the scheme or a
|
|
* subdomain could be matched against a `:` or literal `.` that was likely not intended. It
|
|
* is highly recommended to use the string patterns and only fall back to regular expressions
|
|
* if they as a last resort.
|
|
* - The regular expression must be an instance of RegExp (i.e. not a string.) It is
|
|
* matched against the **entire** *normalized / absolute URL* of the resource being tested
|
|
* (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags
|
|
* present on the RegExp (such as multiline, global, ignoreCase) are ignored.
|
|
* - If you are generating your Javascript from some other templating engine (not
|
|
* recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
|
|
* remember to escape your regular expression (and be aware that you might need more than
|
|
* one level of escaping depending on your templating engine and the way you interpolated
|
|
* the value.) Do make use of your platform's escaping mechanism as it might be good
|
|
* enough before coding your own. e.g. Ruby has
|
|
* [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
|
|
* and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
|
|
* Javascript lacks a similar built in function for escaping. Take a look at Google
|
|
* Closure library's [goog.string.regExpEscape(s)](
|
|
* http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
|
|
*
|
|
* Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

exploit.

|
* ## Can I disable SCE completely?
|
|
*
|
|
* Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
|
|
* for little coding overhead. It will be much harder to take an SCE disabled application and
|
|
* either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
|
|
* for cases where you have a lot of existing code that was written before SCE was introduced and
|
|
* you're migrating them a module at a time.
|
|
*
|
|
* That said, here's how you can completely disable SCE:
|
|
*
|
|
* <pre class="prettyprint">
|
|
* angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
|
|
* // Completely disable SCE. For demonstration purposes only!
|
|
* // Do not use in new projects.
|
|
* $sceProvider.enabled(false);
|
|
* });
|
|
* </pre>

/* Design notes on the default implementation for SCE.
|
|
*
|
|
* The API contract for the SCE delegate
|
|
* -------------------------------------
|
|
* The SCE delegate object must provide the following 3 methods:
|
|
*
|
|
* - trustAs(contextEnum, value)
|
|
* This method is used to tell the SCE service that the provided value is OK to use in the
|
|
* contexts specified by contextEnum. It must return an object that will be accepted by
|
|
* getTrusted() for a compatible contextEnum and return this value.
|
|
*
|
|
* - valueOf(value)
|
|
* For values that were not produced by trustAs(), return them as is. For values that were
|
|
* produced by trustAs(), return the corresponding input value to trustAs. Basically, if
|
|
* trustAs is wrapping the given values into some type, this operation unwraps it when given
|
|
* such a value.
|
|
*
|
|
* - getTrusted(contextEnum, value)
|
|
* This function should return the a value that is safe to use in the context specified by
|
|
* contextEnum or throw and exception otherwise.
|
|
*
|
|
* NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
|
|
* opaque or wrapped in some holder object. That happens to be an implementation detail. For
|
|
* instance, an implementation could maintain a registry of all trusted objects by context. In
|
|
* such a case, trustAs() would return the same object that was passed in. getTrusted() would
|
|
* return the same object passed in if it was found in the registry under a compatible context or
|
|
* throw an exception otherwise. An implementation might only wrap values some of the time based
|
|
* on some criteria. getTrusted() might return a value and not throw an exception for special
|
|
* constants or objects even if not wrapped. All such implementations fulfill this contract.
|
|
*
|
|
*
|
|
* A note on the inheritance model for SCE contexts
|
|
* ------------------------------------------------
|
|
* I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
|
|
* is purely an implementation details.
|
|
*
|
|
* The contract is simply this:
|
|
*
|
|
* getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
|
|
* will also succeed.
|
|
*
|
|
* Inheritance happens to capture this in a natural way. In some future, we
|
|
* may not use inheritance anymore. That is OK because no code outside of
|
|
* sce.js and sceSpecs.js would need to be aware of this detail.

|
|
* Implementation Notes for non-IE browsers
|
|
* ----------------------------------------
|
|
* Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
|
|
* results both in the normalizing and parsing of the URL. Normalizing means that a relative
|
|
* URL will be resolved into an absolute URL in the context of the application document.
|
|
* Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
|
|
* properties are all populated to reflect the normalized URL. This approach has wide
|
|
* compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See
|
|
* http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
|
|
*
|
|
* Implementation Notes for IE
|
|
* ---------------------------
|
|
* IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other
|
|
* browsers. However, the parsed components will not be set if the URL assigned did not specify
|
|
* them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
|
|
* work around that by performing the parsing in a 2nd step by taking a previously normalized
|
|
* URL (e.g. by assining to a.href) and assigning it a.href again. This correctly populates the
|
|
* properties such as protocol, hostname, port, etc.
|
|
*
|
|
* IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one
|
|
* uses the inner HTML approach to assign the URL as part of an HTML snippet -
|
|
* http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL.
|
|
* Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception.
|
|
* Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that
|
|
* method and IE < 8 is unsupported.

|
|

|
|
* @description
|
|
* A reference to the browser's `window` object. While `window`
|
|
* is globally available in JavaScript, it causes testability problems, because
|
|
* it is a global variable. In angular we always refer to it through the
|
|
* `$window` service, so it may be overridden, removed or mocked for testing.
|
|
*
|
|
* Expressions, like the one defined for the `ngClick` directive in the example
|
|
* below, are evaluated with respect to the current scope. Therefore, there is
|
|
* no risk of inadvertently coding in a dependency on a global value in such an
|
|
* expression.

|
|
* @function
|
|
*
|
|
* @description
|
|
* Selects a subset of items from `array` and returns it as a new array.
|
|
*
|
|
* @param {Array} array The source array.
|
|
* @param {string|Object|function()} expression The predicate to be used for selecting items from
|
|
* `array`.
|
|
*
|
|
* Can be one of:
|
|
*
|
|
* - `string`: Predicate that results in a substring match using the value of `expression`
|
|
* string. All strings or objects with string properties in `array` that contain this string
|
|
* will be returned. The predicate can be negated by prefixing the string with `!`.
|
|
*
|
|
* - `Object`: A pattern object can be used to filter specific properties on objects contained
|
|
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
|
|
* which have property `name` containing "M" and property `phone` containing "1". A special
|
|
* property name `$` can be used (as in `{$:"text"}`) to accept a match against any
|
|
* property of the object. That's equivalent to the simple substring match with a `string`
|
|
* as described above.
|
|
*
|
|
* - `function`: A predicate function can be used to write arbitrary filters. The function is
|
|
* called for each element of `array`. The final result is an array of those elements that
|
|
* the predicate returned true for.
|
|
*
|
|
* @param {function(expected, actual)|true|undefined} comparator Comparator which is used in
|
|
* determining if the expected value (from the filter expression) and actual value (from
|
|
* the object in the array) should be considered a match.
|
|
*
|
|
* Can be one of:
|
|
*
|
|
* - `function(expected, actual)`:
|
|
* The function will be given the object value and the predicate value to compare and
|
|
* should return true if the item should be included in filtered result.
|
|
*
|
|
* - `true`: A shorthand for `function(expected, actual) { return angular.equals(expected, actual)}`.
|
|
* this is essentially strict comparison of expected and actual.
|
|
*
|
|
* - `false|undefined`: A short hand for a function which will look for a substring match in case
|
|
* insensitive way.

|
* Formats `date` to a string based on the requested `format`.
|
|
*
|
|
* `format` string can be composed of the following elements:
|
|
*
|
|
* * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
|
|
* * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
|
|
* * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
|
|
* * `'MMMM'`: Month in year (January-December)
|
|
* * `'MMM'`: Month in year (Jan-Dec)
|
|
* * `'MM'`: Month in year, padded (01-12)
|
|
* * `'M'`: Month in year (1-12)
|
|
* * `'dd'`: Day in month, padded (01-31)
|
|
* * `'d'`: Day in month (1-31)
|
|
* * `'EEEE'`: Day in Week,(Sunday-Saturday)
|
|
* * `'EEE'`: Day in Week, (Sun-Sat)
|
|
* * `'HH'`: Hour in day, padded (00-23)
|
|
* * `'H'`: Hour in day (0-23)
|
|
* * `'hh'`: Hour in am/pm, padded (01-12)
|
|
* * `'h'`: Hour in am/pm, (1-12)
|
|
* * `'mm'`: Minute in hour, padded (00-59)
|
|
* * `'m'`: Minute in hour (0-59)
|
|
* * `'ss'`: Second in minute, padded (00-59)
|
|
* * `'s'`: Second in minute (0-59)
|
|
* * `'.sss' or ',sss'`: Millisecond in second, padded (000-999)
|
|
* * `'a'`: am/pm marker
|
|
* * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
|
|
*
|
|
* `format` string can also be one of the following predefined
|
|
* {@link guide/i18n localizable formats}:
|
|
*
|
|
* * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
|
|
* (e.g. Sep 3, 2010 12:05:08 pm)
|
|
* * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 pm)
|
|
* * `'fullDate'`: equivalent to `'EEEE, MMMM d,y'` for en_US locale
|
|
* (e.g. Friday, September 3, 2010)
|
|
* * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
|
|
* * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
|
|
* * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
|
|
* * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 pm)
|
|
* * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 pm)
|
|
*
|
|
* `format` string can contain literal values. These need to be quoted with single quotes (e.g.
|
|
* `"h 'in the morning'"`). In order to output single quote, use two single quotes in a sequence
|
|
* (e.g. `"h 'o''clock'"`).
|
|
*
|
|
* @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
|
|
* number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.SSSZ and its
|
|
* shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
|
|
* specified in the string input, the time is considered to be in the local timezone.
|
|
* @param {string=} format Formatting rules (see Description). If not specified,
|
|
* `mediumDate` is used.
|
|
* @returns {string} Formatted string or the input if input is not recognized as date/millis.

* # Alias: {@link ng.directive:ngForm `ngForm`}
|
|
*
|
|
* In Angular forms can be nested. This means that the outer form is valid when all of the child
|
|
* forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
|
|
* Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to
|
|
* `<form>` but can be nested. This allows you to have nested forms, which is very useful when
|
|
* using Angular validation directives in forms that are dynamically generated using the
|
|
* {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name`
|
|
* attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an
|
|
* `ngForm` directive and nest these in an outer `form` element.
|
|
*
|
|
*
|
|
* # CSS classes
|
|
* - `ng-valid` Is set if the form is valid.
|
|
* - `ng-invalid` Is set if the form is invalid.
|
|
* - `ng-pristine` Is set if the form is pristine.
|
|
* - `ng-dirty` Is set if the form is dirty.
|
|
*
|
|
*
|
|
* # Submitting a form and preventing the default action
|
|
*
|
|
* Since the role of forms in client-side Angular applications is different than in classical
|
|
* roundtrip apps, it is desirable for the browser not to translate the form submission into a full
|
|
* page reload that sends the data to the server. Instead some javascript logic should be triggered
|
|
* to handle the form submission in an application-specific way.
|
|
*
|
|
* For this reason, Angular prevents the default action (form submission to the server) unless the
|
|
* `<form>` element has an `action` attribute specified.
|
|
*
|
|
* You can use one of the following two ways to specify what javascript method should be called when
|
|
* a form is submitted:
|
|
*
|
|
* - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
|
|
* - {@link ng.directive:ngClick ngClick} directive on the first
|
|
* button or input field of type submit (input[type=submit])
|
|
*
|
|
* To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
|
|
* or {@link ng.directive:ngClick ngClick} directives.
|
|
* This is because of the following form submission rules in the HTML specification:
|
|
*
|
|
* - If a form has only one input field then hitting enter in this field triggers form submit
|
|
* (`ngSubmit`)
|
|
* - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
|
|
* doesn't trigger submit
|
|
* - if a form has one or more input fields and one or more buttons or input[type=submit] then
|
|
* hitting enter in any of the input fields will trigger the click handler on the *first* button or
|
|
* input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
|
|
*
|
|
* @param {string=} name Name of the form. If specified, the form controller will be published into
|
|
* related scope, under this name.

|
|
*
|
|
* `NgModelController` provides API for the `ng-model` directive. The controller contains
|
|
* services for data-binding, validation, CSS updates, and value formatting and parsing. It
|
|
* purposefully does not contain any logic which deals with DOM rendering or listening to
|
|
* DOM events. Such DOM related logic should be provided by other directives which make use of
|
|
* `NgModelController` for data-binding.
|
|
*
|
|
* ## Custom Control Example
|
|
* This example shows how to use `NgModelController` with a custom control to achieve
|
|
* data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
|
|
* collaborate together to achieve the desired result.
|
|
*
|
|
* Note that `contenteditable` is an HTML5 attribute, which tells the browser to let the element
|
|
* contents be edited in place by the user. This will not work on older browsers.
|
|
*
|
|
* <example module="customControl">
|
|
<file name="style.css">
|
|
[contenteditable] {
|
|
border: 1px solid black;
|
|
background-color: white;
|
|
min-height: 20px;
|
|
}
|
|
|
|
.ng-invalid {
|
|
border: 1px solid red;
|
|
}
|
|
|
|
</file>
|
|
<file name="script.js">
|
|
angular.module('customControl', []).
|
|
directive('contenteditable', function() {
|
|
return {
|
|
restrict: 'A', // only activate on element attribute
|
|
require: '?ngModel', // get a hold of NgModelController
|
|
link: function(scope, element, attrs, ngModel) {
|
|
if(!ngModel) return; // do nothing if no ng-model
|
|
|
|
// Specify how UI should be updated
|
|
ngModel.$render = function() {
|
|
element.html(ngModel.$viewValue || '');
|
|
};
|
|
|
|
// Listen for change events to enable binding
|
|
element.on('blur keyup change', function() {
|
|
scope.$apply(read);
|
|
});
|
|
read(); // initialize
|
|
|
|
// Write data to the model
|
|
function read() {
|
|
var html = element.html();
|
|
// When we clear the content editable the browser leaves a <br> behind

*
|
|
* ## Isolated Scope Pitfall
|
|
*
|
|
* Note that if you have a directive with an isolated scope, you cannot require `ngModel`
|
|
* since the model value will be looked up on the isolated scope rather than the outer scope.
|
|
* When the directive updates the model value, calling `ngModel.$setViewValue()` the property
|
|
* on the outer scope will not be updated. However you can get around this by using $parent.
|
|
*
|
|
* Here is an example of this situation. You'll notice that the first div is not updating the input.
|
|
* However the second div can update the input properly.
|
|
*
|
|
* <example module="badIsolatedDirective">
|
|
<file name="script.js">
|
|
angular.module('badIsolatedDirective', []).directive('isolate', function() {
|
|
return {
|
|
require: 'ngModel',
|
|
scope: { },
|
|
template: '<input ng-model="innerModel">',
|
|
link: function(scope, element, attrs, ngModel) {
|
|
scope.$watch('innerModel', function(value) {
|
|
console.log(value);
|
|
ngModel.$setViewValue(value);
|
|
});
|
|
}
|
|
};
|
|
});
|
|
</file>
|
|
<file name="index.html">
|
|
<input ng-model="someModel"/>
|
|
<div isolate ng-model="someModel"></div>
|
|
<div isolate ng-model="$parent.someModel"></div>

|
* `ngModel` is responsible for:
|
|
*
|
|
* - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
|
|
* require.
|
|
* - Providing validation behavior (i.e. required, number, email, url).
|
|
* - Keeping the state of the control (valid/invalid, dirty/pristine, validation errors).
|
|
* - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`).
|
|
* - Registering the control with its parent {@link ng.directive:form form}.
|
|
*
|
|
* Note: `ngModel` will try to bind to the property given by evaluating the expression on the
|
|
* current scope. If the property doesn't already exist on this scope, it will be created
|
|
* implicitly and added to the scope.
|
|
*
|
|
* For best practices on using `ngModel`, see:
|
|
*
|
|
* - {@link https://github.com/angular/angular.js/wiki/Understanding-Scopes}
|
|
*
|
|
* For basic examples, how to use `ngModel`, see:
|
|
*
|
|
* - {@link ng.directive:input input}
|
|
* - {@link ng.directive:input.text text}
|

* @description
|
|
* The `ngBind` attribute tells Angular to replace the text content of the specified HTML element
|
|
* with the value of a given expression, and to update the text content when the value of that
|
|
* expression changes.
|
|
*
|
|
* Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
|
|
* `{{ expression }}` which is similar but less verbose.
|
|
*
|
|
* It is preferrable to use `ngBind` instead of `{{ expression }}` when a template is momentarily
|
|
* displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
|
|
* element attribute, it makes the bindings invisible to the user while the page is loading.
|
|
*
|
|
* An alternative solution to this problem would be using the
|
|
* {@link ng.directive:ngCloak ngCloak} directive.

* @description
|
|
* The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
|
|
* an expression that represents all classes to be added.
|
|
*
|
|
* The directive won't add duplicate classes if a particular class was already set.
|
|
*
|
|
* When the expression changes, the previously added classes are removed and only then the
|
|
* new classes are added.
|
|
*
|
|
* @animations
|
|
* add - happens just before the class is applied to the element
|
|
* remove - happens just before the class is removed from the element
|
|
*
|
|
* @element ANY
|
|
* @param {expression} ngClass {@link guide/expression Expression} to eval. The result
|
|
* of the evaluation can be a string representing space delimited class
|
|
* names, an array, or a map of class names to boolean values. In the case of a map, the
|
|
* names of the properties whose values are truthy will be added as css classes to the
|
|
* element.

|
|
## ngClass and pre-existing CSS3 Transitions/Animations
|
|
The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
|
|
Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
|
|
any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
|
|
to view the step by step details of {@link ngAnimate.$animate#methods_addclass $animate.addClass} and
|
|
{@link ngAnimate.$animate#methods_removeclass $animate.removeClass}.

|
|
*
|
|
* @description
|
|
* The `ngCloak` directive is used to prevent the Angular html template from being briefly
|
|
* displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
|
|
* directive to avoid the undesirable flicker effect caused by the html template display.
|
|
*
|
|
* The directive can be applied to the `<body>` element, but the preferred usage is to apply
|
|
* multiple `ngCloak` directives to small portions of the page to permit progressive rendering
|
|
* of the browser view.
|
|
*
|
|
* `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
|
|
* `angular.min.js`.
|
|
* For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
|
|
*
|
|
* <pre>
|
|
* [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
|
|
* display: none !important;
|
|
* }
|
|
* </pre>
|
|
*
|
|
* When this css rule is loaded by the browser, all html elements (including their children) that
|
|
* are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
|
|
* during the compilation of the template it deletes the `ngCloak` element attribute, making
|
|
* the compiled element visible.
|
|
*
|
|
* For the best result, the `angular.js` script must be loaded in the head section of the html
|
|
* document; alternatively, the css rule above must be included in the external stylesheet of the
|
|
* application.
|
|
*
|
|
* Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
|
|
* cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
|
|
* class `ngCloak` in addition to the `ngCloak` directive as shown in the example below.

*

* @element ANY

|
|
*
|
|
* @description
|
|
* The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
|
|
* supports the principles behind the Model-View-Controller design pattern.
|
|
*
|
|
* MVC components in angular:
|
|
*
|
|
* * Model — The Model is scope properties; scopes are attached to the DOM where scope properties
|
|
* are accessed through bindings.
|
|
* * View — The template (HTML with data bindings) that is rendered into the View.
|
|
* * Controller — The `ngController` directive specifies a Controller class; the class contains business
|
|
* logic behind the application to decorate the scope with functions and values
|
|
*
|
|
* Note that you can also attach controllers to the DOM by declaring it in a route definition
|
|
* via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
|
|
* again using `ng-controller` in the template itself. This will cause the controller to be attached
|
|
* and executed twice.
|
|
*
|
|
* @element ANY
|
|
* @scope
|
|
* @param {expression} ngController Name of a globally accessible constructor function or an
|
|
* {@link guide/expression expression} that on the current scope evaluates to a
|
|
* constructor function. The controller instance can be published into a scope property
|
|
* by specifying `as propertyName`.
|
|
*
|
|
* @example
|
|
* Here is a simple form for editing user contact information. Adding, removing, clearing, and
|
|
* greeting are methods declared on the controller (see source tab). These methods can
|
|
* easily be called from the angular markup. Notice that the scope becomes the `this` for the
|
|
* controller's instance. This allows for easy access to the view data from the controller. Also
|
|
* notice that any changes to the data are automatically reflected in the View without the need
|
|
* for a manual update. The example is shown in two different declaration styles you may use
|
|
* according to preference.

|

* @name ng.directive:ngIf
|
|
* @restrict A
|
|
*
|
|
* @description
|
|
* The `ngIf` directive removes or recreates a portion of the DOM tree based on an
|
|
* {expression}. If the expression assigned to `ngIf` evaluates to a false
|
|
* value then the element is removed from the DOM, otherwise a clone of the
|
|
* element is reinserted into the DOM.
|
|
*
|
|
* `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
|
|
* element in the DOM rather than changing its visibility via the `display` css property. A common
|
|
* case when this difference is significant is when using css selectors that rely on an element's
|
|
* position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
|
|
*
|
|
* Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
|
|
* is created when the element is restored. The scope created within `ngIf` inherits from
|
|
* its parent scope using
|
|
* {@link https://github.com/angular/angular.js/wiki/The-Nuances-of-Scope-Prototypal-Inheritance prototypal inheritance}.
|
|
* An important implication of this is if `ngModel` is used within `ngIf` to bind to
|
|
* a javascript primitive defined in the parent scope. In this case any modifications made to the
|
|
* variable within the child scope will override (hide) the value in the parent scope.
|
|
*
|
|
* Also, `ngIf` recreates elements using their compiled state. An example of this behavior
|
|
* is if an element's class attribute is directly modified after it's compiled, using something like
|
|
* jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
|
|
* the added class will be lost because the original compiled state is used to regenerate the element.
|
|
*
|
|
* Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
|
|
* and `leave` effects.
|
|
*
|
|
* @animations
|
|
* enter - happens just after the ngIf contents change and a new DOM element is created and injected into the ngIf container
|
|
* leave - happens just before the ngIf contents are removed from the DOM
|
|
*
|
|
* @element ANY
|
|
* @scope
|
|
* @priority 600
|
|
* @param {expression} ngIf If the {@link guide/expression expression} is falsy then
|
|
* the element is removed from the DOM tree. If it is truthy a copy of the compiled
|
|
* element is added to the DOM tree.
|
|

|
|
* @description
|
|
* # Overview
|
|
* `ngPluralize` is a directive that displays messages according to en-US localization rules.
|
|
* These rules are bundled with angular.js, but can be overridden
|
|
* (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
|
|
* by specifying the mappings between
|
|
* {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
|
|
* plural categories} and the strings to be displayed.
|
|
*
|
|
* # Plural categories and explicit number rules
|
|
* There are two
|
|
* {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
|
|
* plural categories} in Angular's default en-US locale: "one" and "other".
|
|
*
|
|
* While a plural category may match many numbers (for example, in en-US locale, "other" can match
|
|
* any number that is not 1), an explicit number rule can only match one number. For example, the
|
|
* explicit number rule for "3" matches the number 3. There are examples of plural categories
|
|
* and explicit number rules throughout the rest of this documentation.
|
|
*
|
|
* # Configuring ngPluralize
|
|
* You configure ngPluralize by providing 2 attributes: `count` and `when`.
|
|
* You can also provide an optional attribute, `offset`.
|
|
*
|
|
* The value of the `count` attribute can be either a string or an {@link guide/expression
|
|
* Angular expression}; these are evaluated on the current scope for its bound value.
|
|
*
|
|
* The `when` attribute specifies the mappings between plural categories and the actual
|
|
* string to be displayed. The value of the attribute should be a JSON object.
|
|
*
|
|
* The following example shows how to configure ngPluralize:
|
|
*
|
|
* <pre>
|
|
* <ng-pluralize count="personCount"
|
|
when="{'0': 'Nobody is viewing.',
|
|
* 'one': '1 person is viewing.',
|
|
* 'other': '{} people are viewing.'}">
|
|
* </ng-pluralize>
|
|
*</pre>
|
|
*
|
|
* In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
|
|
* specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
|
|
* would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
|
|
* other numbers, for example 12, so that instead of showing "12 people are viewing", you can
|
|
* show "a dozen people are viewing".
|
|
*
|
|
* You can use a set of closed braces(`{}`) as a placeholder for the number that you want substituted
|
|
* into pluralized strings. In the previous example, Angular will replace `{}` with
|
|
* <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
|
|
* for <span ng-non-bindable>{{numberExpression}}</span>.
|
|
*
|
|
* # Configuring ngPluralize with offset
|
|
* The `offset` attribute allows further customization of pluralized text, which can result in
|
|
* a better user experience. For example, instead of the message "4 people are viewing this document",
|
|
* you might display "John, Kate and 2 others are viewing this document".
|
|
* The offset attribute allows you to offset a number by any desired value.
|
|
* Let's take a look at an example:
|
|
*
|
|
* <pre>
|
|
* <ng-pluralize count="personCount" offset=2
|
|
* when="{'0': 'Nobody is viewing.',
|
|
* '1': '{{person1}} is viewing.',
|
|
* '2': '{{person1}} and {{person2}} are viewing.',
|
|
* 'one': '{{person1}}, {{person2}} and one other person are viewing.',
|
|
* 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
|
|
* </ng-pluralize>
|
|
* </pre>
|
|
*
|
|
* Notice that we are still using two plural categories(one, other), but we added
|
|
* three explicit number rules 0, 1 and 2.
|
|
* When one person, perhaps John, views the document, "John is viewing" will be shown.
|
|
* When three people view the document, no explicit number rule is found, so
|
|
* an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
|
|
* In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
|
|
* is shown.
|
|
*
|
|
* Note that when you specify offsets, you must provide explicit number rules for
|
|
* numbers from 0 up to and including the offset. If you use an offset of 3, for example,
|
|
* you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
|
|
* plural categories "one" and "other".
|
|
*
|
|
* @param {string|expression} count The variable to be bounded to.
|
|
* @param {string} when The mapping between plural category to its corresponding strings.
|
|
* @param {number=} offset Offset to deduct from the total number.
|
|
*

|
|
* The `ngRepeat` directive instantiates a template once per item from a collection. Each template
|
|
* instance gets its own scope, where the given loop variable is set to the current collection item,
|
|
* and `$index` is set to the item index or key.
|
|
*
|
|
* Special properties are exposed on the local scope of each template instance, including:
|
|
*
|
|
* | Variable | Type | Details |
|
|
* |-----------|-----------------|-----------------------------------------------------------------------------|
|
|
* | `$index` | {@type number} | iterator offset of the repeated element (0..length-1) |
|
|
* | `$first` | {@type boolean} | true if the repeated element is first in the iterator. |
|
|
* | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
|
|
* | `$last` | {@type boolean} | true if the repeated element is last in the iterator. |
|
|
* | `$even` | {@type boolean} | true if the iterator position `$index` is even (otherwise false). |
|
|
* | `$odd` | {@type boolean} | true if the iterator position `$index` is odd (otherwise false). |
|
|
*
|
|
*
|
|
* # Special repeat start and end points
|
|
* To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
|
|
* the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.

* The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
|
|
* up to and including the ending HTML tag where **ng-repeat-end** is placed.
|
|
*
|
|
* The example below makes use of this feature:
|
|
* <pre>
|
|
* <header ng-repeat-start="item in items">
|
|
* Header {{ item }}
|
|
* </header>
|
|
* <div class="body">
|
|
* Body {{ item }}
|
|
* </div>
|
|
* <footer ng-repeat-end>
|
|
* Footer {{ item }}
|
|
* </footer>
|
|
* </pre>
|
|
*
|
|
* And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
|
|
* <pre>
|
|
* <header>
|
|
* Header A
|
|
* </header>
|
|
* <div class="body">
|
|
* Body A
|
|
* </div>
|
|
* <footer>
|
|
* Footer A
|
|
* </footer>
|
|
* <header>
|
|
* Header B
|
|
* </header>
|
|
* <div class="body">
|
|
* Body B
|
|
* </div>
|
|
* <footer>
|
|
* Footer B
|
|
* </footer>
|
|
* </pre>
|
|
*
|
|
* The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
|
|
* as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
|
|
*
|
|
* @animations
|
|
* enter - when a new item is added to the list or when an item is revealed after a filter
|
|
* leave - when an item is removed from the list or when an item is filtered out
|
|
* move - when an adjacent item is filtered out causing a reorder or when the item contents are reordered
|

|
* @element ANY
|
|
* @scope
|
|
* @priority 1000
|
|
* @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
|
|
* formats are currently supported:
|
|
*
|
|
* * `variable in expression` – where variable is the user defined loop variable and `expression`
|
|
* is a scope expression giving the collection to enumerate.
|
|
*
|
|
* For example: `album in artist.albums`.
|
|
*
|
|
* * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
|
|
* and `expression` is the scope expression giving the collection to enumerate.
|
|
*
|
|
* For example: `(name, age) in {'adam':10, 'amalie':12}`.
|
|
*
|
|
* * `variable in expression track by tracking_expression` – You can also provide an optional tracking function
|
|
* which can be used to associate the objects in the collection with the DOM elements. If no tracking function
|
|
* is specified the ng-repeat associates elements by identity in the collection. It is an error to have
|
|
* more than one tracking function to resolve to the same key. (This would mean that two distinct objects are
|
|
* mapped to the same DOM element, which is not possible.) Filters should be applied to the expression,
|
|
* before specifying a tracking expression.
|
|
*
|
|
* For example: `item in items` is equivalent to `item in items track by $id(item)'. This implies that the DOM elements
|
|
* will be associated by item identity in the array.
|
|
*
|
|
* For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
|
|
* `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
|
|
* with the corresponding item in the array by identity. Moving the same object in array would move the DOM
|
|
* element in the same way ian the DOM.
|
|
*
|
|
* For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
|
|
* case the object identity does not matter. Two objects are considered equivalent as long as their `id`
|
|
* property is same.
|
|
*
|
|
* For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
|
|
* to items in conjunction with a tracking expression.
|
|
*
|
|
* @example
|
|
* This example initializes the scope to a list of names and
|
|
* then uses `ngRepeat` to display every person:

/**
|
|
* @ngdoc directive
|
|
* @name ng.directive:ngShow
|
|
*
|
|
* @description
|
|
* The `ngShow` directive shows or hides the given HTML element based on the expression
|
|
* provided to the ngShow attribute. The element is shown or hidden by removing or adding
|
|
* the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
|
|
* in AngularJS and sets the display style to none (using an !important flag).
|
|
* For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
|
|
*
|
|
* <pre>
|
|
* <!-- when $scope.myValue is truthy (element is visible) -->
|
|
* <div ng-show="myValue"></div>
|
|
*
|
|
* <!-- when $scope.myValue is falsy (element is hidden) -->
|
|
* <div ng-show="myValue" class="ng-hide"></div>
|
|
* </pre>
|
|
*
|
|
* When the ngShow expression evaluates to false then the ng-hide CSS class is added to the class attribute
|
|
* on the element causing it to become hidden. When true, the ng-hide CSS class is removed
|
|
* from the element causing the element not to appear hidden.
|
|
*
|
|
* ## Why is !important used?
|
|
*
|
|
* You may be wondering why !important is used for the .ng-hide CSS class. This is because the `.ng-hide` selector
|
|
* can be easily overridden by heavier selectors. For example, something as simple
|
|
* as changing the display style on a HTML list item would make hidden elements appear visible.
|
|
* This also becomes a bigger issue when dealing with CSS frameworks.
|
|
*
|
|
* By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
|
|
* specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
|
|
* styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
|
|
*
|
|
* ### Overriding .ng-hide
|
|
*
|
|
* If you wish to change the hide behavior with ngShow/ngHide then this can be achieved by
|
|
* restating the styles for the .ng-hide class in CSS:
|
|
* <pre>
|
|
* .ng-hide {
|
|
* //!annotate CSS Specificity|Not to worry, this will override the AngularJS default...
|
|
* display:block!important;
|
|
*
|
|
* //this is just another form of hiding an element
|
|
* position:absolute;
|
|
* top:-9999px;
|
|
* left:-9999px;
|
|
* }
|
|
* </pre>
|
|
*
|
|
* Just remember to include the important flag so the CSS override will function.
|
|
*
|
|
* ## A note about animations with ngShow
|
|
*
|
|
* Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
|
|
* is true and false. This system works like the animation system present with ngClass except that
|
|
* you must also include the !important flag to override the display property
|
|
* so that you can perform an animation when the element is hidden during the time of the animation.
|
|
*
|
|
* <pre>
|
|
* //
|
|
* //a working example can be found at the bottom of this page
|
|
* //
|
|
* .my-element.ng-hide-add, .my-element.ng-hide-remove {
|
|
* transition:0.5s linear all;
|
|
* display:block!important;
|
|
* }
|
|
*
|
|
* .my-element.ng-hide-add { ... }
|
|
* .my-element.ng-hide-add.ng-hide-add-active { ... }
|
|
* .my-element.ng-hide-remove { ... }
|
|
* .my-element.ng-hide-remove.ng-hide-remove-active { ... }
|
|
* </pre>
|
|
*
|
|
* @animations
|
|
* addClass: .ng-hide - happens after the ngShow expression evaluates to a truthy value and the just before contents are set to visible
|
|
* removeClass: .ng-hide - happens after the ngShow expression evaluates to a non truthy value and just before the contents are set to hidden
|
|
*
|
|
* @element ANY
|
|
* @param {expression} ngShow If the {@link guide/expression expression} is truthy
|
|
* then the element is shown or hidden respectively.

/**
|
|
* @ngdoc directive
|
|
* @name ng.directive:ngHide
|
|
*
|
|
* @description
|
|
* The `ngHide` directive shows or hides the given HTML element based on the expression
|
|
* provided to the ngHide attribute. The element is shown or hidden by removing or adding
|
|
* the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
|
|
* in AngularJS and sets the display style to none (using an !important flag).
|
|
* For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
|
|
*
|
|
* <pre>
|
|
* <!-- when $scope.myValue is truthy (element is hidden) -->
|
|
* <div ng-hide="myValue"></div>
|
|
*
|
|
* <!-- when $scope.myValue is falsy (element is visible) -->
|
|
* <div ng-hide="myValue" class="ng-hide"></div>
|
|
* </pre>
|
|
*
|
|
* When the ngHide expression evaluates to true then the .ng-hide CSS class is added to the class attribute
|
|
* on the element causing it to become hidden. When false, the ng-hide CSS class is removed
|
|
* from the element causing the element not to appear hidden.
|
|
*
|
|
* ## Why is !important used?
|
|
*
|
|
* You may be wondering why !important is used for the .ng-hide CSS class. This is because the `.ng-hide` selector
|
|
* can be easily overridden by heavier selectors. For example, something as simple
|
|
* as changing the display style on a HTML list item would make hidden elements appear visible.
|
|
* This also becomes a bigger issue when dealing with CSS frameworks.
|
|
*
|
|
* By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
|
|
* specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
|
|
* styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
|
|
*
|
|
* ### Overriding .ng-hide
|
|
*
|
|
* If you wish to change the hide behavior with ngShow/ngHide then this can be achieved by
|
|
* restating the styles for the .ng-hide class in CSS:
|
|
* <pre>
|
|
* .ng-hide {
|
|
* //!annotate CSS Specificity|Not to worry, this will override the AngularJS default...
|
|
* display:block!important;
|
|
*
|
|
* //this is just another form of hiding an element
|
|
* position:absolute;
|
|
* top:-9999px;
|
|
* left:-9999px;
|
|
* }
|
|
* </pre>
|
|
*
|
|
* Just remember to include the important flag so the CSS override will function.
|
|
*
|
|
* ## A note about animations with ngHide
|
|
*
|
|
* Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
|
|
* is true and false. This system works like the animation system present with ngClass, except that
|
|
* you must also include the !important flag to override the display property so
|
|
* that you can perform an animation when the element is hidden during the time of the animation.
|
|
*
|
|
* <pre>
|
|
* //
|
|
* //a working example can be found at the bottom of this page
|
|
* //
|
|
* .my-element.ng-hide-add, .my-element.ng-hide-remove {
|
|
* transition:0.5s linear all;
|
|
* display:block!important;
|
|
* }
|
|
*
|
|
* .my-element.ng-hide-add { ... }
|
|
* .my-element.ng-hide-add.ng-hide-add-active { ... }
|
|
* .my-element.ng-hide-remove { ... }
|
|
* .my-element.ng-hide-remove.ng-hide-remove-active { ... }
|
|
* </pre>
|
|
*
|
|
* @animations
|
|
* removeClass: .ng-hide - happens after the ngHide expression evaluates to a truthy value and just before the contents are set to hidden
|
|
* addClass: .ng-hide - happens after the ngHide expression evaluates to a non truthy value and just before the contents are set to visible
|
|
*
|
|
* @element ANY
|
|
* @param {expression} ngHide If the {@link guide/expression expression} is truthy then
|
|
* the element is shown or hidden respectively.

|
|
* @description
|
|
* The ngSwitch directive is used to conditionally swap DOM structure on your template based on a scope expression.
|
|
* Elements within ngSwitch but without ngSwitchWhen or ngSwitchDefault directives will be preserved at the location
|
|
* as specified in the template.
|
|
*
|
|
* The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
|
|
* from the template cache), ngSwitch simply choses one of the nested elements and makes it visible based on which element
|
|
* matches the value obtained from the evaluated expression. In other words, you define a container element
|
|
* (where you place the directive), place an expression on the **on="..." attribute**
|
|
* (or the **ng-switch="..." attribute**), define any inner elements inside of the directive and place
|
|
* a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
|
|
* expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
|
|
* attribute is displayed.
|
|
*
|
|
* @animations
|
|
* enter - happens after the ngSwitch contents change and the matched child element is placed inside the container
|
|
* leave - happens just after the ngSwitch contents change and just before the former contents are removed from the DOM
|
|
*
|
|
* @usage
|
|
* <ANY ng-switch="expression">
|
|
* <ANY ng-switch-when="matchValue1">...</ANY>

|
|
* @paramDescription
|
|
* On child elements add:
|
|
*
|
|
* * `ngSwitchWhen`: the case statement to match against. If match then this
|
|
* case will be displayed. If the same match appears multiple times, all the
|
|
* elements will be displayed.
|
|
* * `ngSwitchDefault`: the default case when no other case match. If there
|
|
* are multiple default cases, all of them will be displayed when no other
|
|
* case match.

|
|
* @description
|
|
* HTML `SELECT` element with angular data-binding.
|
|
*
|
|
* # `ngOptions`
|
|
*
|
|
* The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
|
|
* elements for the `<select>` element using the array or object obtained by evaluating the
|
|
* `ngOptions` comprehension_expression.
|
|
*
|
|
* When an item in the `<select>` menu is selected, the array element or object property
|
|
* represented by the selected option will be bound to the model identified by the `ngModel`
|
|
* directive.
|
|
*
|
|
* Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
|
|
* be nested into the `<select>` element. This element will then represent the `null` or "not selected"
|
|
* option. See example below for demonstration.
|
|
*
|
|
* Note: `ngOptions` provides iterator facility for `<option>` element which should be used instead
|
|
* of {@link ng.directive:ngRepeat ngRepeat} when you want the
|
|
* `select` model to be bound to a non-string value. This is because an option element can only
|
|
* be bound to string values at present.
|
|
*
|
|
* @param {string} ngModel Assignable angular expression to data-bind to.
|
|
* @param {string=} name Property name of the form under which the control is published.
|
|
* @param {string=} required The control is considered valid only if value is entered.
|
|
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
|
|
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
|
|
* `required` when you want to data-bind to the `required` attribute.
|
|
* @param {comprehension_expression=} ngOptions in one of the following forms:
|
|
*
|
|
* * for array data sources:
|
|
* * `label` **`for`** `value` **`in`** `array`
|
|
* * `select` **`as`** `label` **`for`** `value` **`in`** `array`
|
|
* * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
|
|
* * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
|
|
* * for object data sources:
|
|
* * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
|
|
* * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
|
|
* * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
|
|
* * `select` **`as`** `label` **`group by`** `group`
|
|
* **`for` `(`**`key`**`,`** `value`**`) in`** `object`
|
|
*
|
|
* Where:
|
|
*
|
|
* * `array` / `object`: an expression which evaluates to an array / object to iterate over.
|
|
* * `value`: local variable which will refer to each item in the `array` or each property value
|
|
* of `object` during iteration.
|
|
* * `key`: local variable which will refer to a property name in `object` during iteration.
|
|
* * `label`: The result of this expression will be the label for `<option>` element. The
|
|
* `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
|
|
* * `select`: The result of this expression will be bound to the model of the parent `<select>`
|
|
* element. If not specified, `select` expression will default to `value`.
|
|
* * `group`: The result of this expression will be used to group options using the `<optgroup>`
|
|
* DOM element.
|
|
* * `trackexpr`: Used when working with an array of objects. The result of this expression will be
|
|
* used to identify the objects in the array. The `trackexpr` will most likely refer to the
|
|
* `value` variable (e.g. `value.propertyName`).
