<div class="description"><div class="ng-directive-page ng-directive-ngselected-page"><p>The HTML specs do not require browsers to preserve the special attributes such as selected.
|
|
(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 introduced the <code>ngSelected</code> directive.</p>
