<div class="description"><div class="ng-directive-page ng-directive-ngdisabled-page"><p>The following markup will make the button enabled on Chrome/Firefox but not on IE8 and older IEs:
|
|
<pre class="prettyprint linenums">
|
|
<div ng-init="scope = { isDisabled: false }">
|
|
<button disabled="{{scope.isDisabled}}">Disabled</button>
|
|
</div>
|
|
</pre>
|
|
<p>The HTML specs do not require browsers to preserve the special attributes such as disabled.
|
|
(The presence of them means true and absence means false)
|
|
This prevents the angular compiler from correctly retrieving the binding expression.
|
|
To solve this problem, we introduce the <code>ngDisabled</code> directive.</p>
