## Usage
|
|
|
|
Enable dismissal of an alert via JavaScript:
|
|
|
|
{% highlight js %}
|
|
$(".alert").alert()
|
|
{% endhighlight %}
|
|
|
|
### Markup
|
|
|
|
Just add `data-dismiss="alert"` to your close button to automatically give an alert close functionality.
|
|
|
|
{% highlight html %}
|
|
<button type="button" class="close" data-dismiss="alert">
|
|
<span aria-hidden="true">×</span>
|
|
<span class="sr-only">Close</span>
|
|
</button>
|
|
{% endhighlight %}
|
|
|
|
### Methods
|
|
|
|
#### $().alert()
|
|
|
|
Wraps all alerts with close functionality. To have your alerts animate out when closed, make sure they have the `.fade` and `.in` class already applied to them.
|
|
|
|
#### .alert('close')
|
|
|
|
Closes an alert.
|
|
|
|
{% highlight js %}$(".alert").alert('close'){% endhighlight %}
|
|
|
|
### Events
|
|
|
|
Bootstrap's alert class exposes a few events for hooking into alert functionality.
|
|
|
|
<div class="table-responsive">
|
|
<table class="table table-bordered table-striped">
|
|
<thead>
|
|
<tr>
|
|
<th style="width: 150px;">Event Type</th>
|
|
<th>Description</th>
|
|
</tr>
|
|
</thead>
|
|
<tbody>
|
|
<tr>
|
|
<td>close.bs.alert</td>
|
|
<td>This event fires immediately when the <code>close</code> instance method is called.</td>
|
|
</tr>
|
|
<tr>
|
|
<td>closed.bs.alert</td>
|
|
<td>This event is fired when the alert has been closed (will wait for CSS transitions to complete).</td>
|
|
</tr>
|
|
</tbody>
|
|
</table>
|
|
</div>
|
|
|
|
{% highlight js %}
|
|
$('#my-alert').on('closed.bs.alert', function () {
|
|
// do something…
|
|
})
|
|
{% endhighlight %}
