|
||
* @description
|
||
*
|
||
* The `ngAria` module provides support for common
|
||
* [<abbr title="Accessible Rich Internet Applications">ARIA</abbr>](http://www.w3.org/TR/wai-aria/)
|
||
* attributes that convey state or semantic information about the application for users
|
||
* of assistive technologies, such as screen readers.
|
||
*
|
||
* <div doc-module-components="ngAria"></div>
|
||
*
|
||
* ## Usage
|
||
*
|
||
* For ngAria to do its magic, simply include the module as a dependency. The directives supported
|
||
* by ngAria are:
|
||
* `ngModel`, `ngDisabled`, `ngShow`, `ngHide`, `ngClick`, `ngDblClick`, and `ngMessages`.
|
||
*
|
||
* Below is a more detailed breakdown of the attributes handled by ngAria:
|
||
*
|
||
* | Directive | Supported Attributes |
|
||
* |---------------------------------------------|----------------------------------------------------------------------------------------|
|
||
* | {@link ng.directive:ngDisabled ngDisabled} | aria-disabled |
|
||
* | {@link ng.directive:ngShow ngShow} | aria-hidden |
|
||
* | {@link ng.directive:ngHide ngHide} | aria-hidden |
|
||
* | {@link ng.directive:ngDblclick ngDblclick} | tabindex |
|
||
* | {@link module:ngMessages ngMessages} | aria-live |
|
||
* | {@link ng.directive:ngModel ngModel} | aria-checked, aria-valuemin, aria-valuemax, aria-valuenow, aria-invalid, aria-required, input roles |
|
||
* | {@link ng.directive:ngClick ngClick} | tabindex, keypress event, button role |
|
||
*
|
||
* Find out more information about each directive by reading the
|
||
* {@link guide/accessibility ngAria Developer Guide}.
|
||
*
|
||
* ##Example
|
||
* Using ngDisabled with ngAria:
|
||
* ```html
|
||
* <md-checkbox ng-disabled="disabled">
|
||
* ```
|
||
* Becomes:
|
||
* ```html
|
||
* <md-checkbox ng-disabled="disabled" aria-disabled="true">
|
||
* ```
|
||
*
|
||
* ##Disabling Attributes
|
||
* It's possible to disable individual attributes added by ngAria with the
|
||
* {@link ngAria.$ariaProvider#config config} method. For more details, see the
|
||
* {@link guide/accessibility Developer Guide}.

|
||
*
|
||
* The $aria service contains helper methods for applying common
|
||
* [ARIA](http://www.w3.org/TR/wai-aria/) attributes to HTML directives.
|
||
*
|
||
* ngAria injects common accessibility attributes that tell assistive technologies when HTML
|
||
* elements are enabled, selected, hidden, and more. To see how this is performed with ngAria,
|
||
* let's review a code snippet from ngAria itself:
|
||
*
|
||
*```js
|
||
* ngAriaModule.directive('ngDisabled', ['$aria', function($aria) {
|
||
* return $aria.$$watchExpr('ngDisabled', 'aria-disabled');
|
||
* }])
|
||
*```
|
||
* Shown above, the ngAria module creates a directive with the same signature as the
|
||
* traditional `ng-disabled` directive. But this ngAria version is dedicated to
|
||
* solely managing accessibility attributes. The internal `$aria` service is used to watch the
|
||
* boolean attribute `ngDisabled`. If it has not been explicitly set by the developer,
|
||
* `aria-disabled` is injected as an attribute with its value synchronized to the value in
|
||
* `ngDisabled`.
|
||
*
|
||
* Because ngAria hooks into the `ng-disabled` directive, developers do not have to do
|
||
* anything to enable this feature. The `aria-disabled` attribute is automatically managed
|
||
* simply as a silent side-effect of using `ng-disabled` with the ngAria module.
|
||
*
|
||
* The full list of directives that interface with ngAria:
|
||
* * **ngModel**
|
||
* * **ngShow**
|
||
* * **ngHide**
|
||
* * **ngClick**
|
||
* * **ngDblclick**
|
||
* * **ngMessages**
|
||
* * **ngDisabled**
|
||
*
|
||
* Read the {@link guide/accessibility ngAria Developer Guide} for a thorough explanation of each
|
||
* directive.
|
||
*
|
||
*
|
||
* ## Dependencies
|
||
* Requires the {@link ngAria} module to be installed.
