|
Add dismiss functionality to all alert messages with this plugin.
|
|
|
|
## Examples
|
|
|
|
{% example html %}
|
|
<div class="alert alert-warning alert-dismissible fade in" role="alert">
|
|
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
|
|
<span aria-hidden="true">×</span>
|
|
<span class="sr-only">Close</span>
|
|
</button>
|
|
<strong>Holy guacamole!</strong> Best check yo self, you're not looking too good.
|
|
</div>
|
|
{% endexample %}
|
|
|
|
When using a `.close` button, it must be the first child of the `.alert-dismissible` and no text content may come before it in the markup.
|
|
|
|
{% example html %}
|
|
<div class="alert alert-danger alert-dismissible fade in" role="alert">
|
|
<button type="button" class="close" data-dismiss="alert"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
|
|
<h5 class="alert-heading">Sorry, something went wrong.</h5>
|
|
<p>Change this and that and try again. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Cras mattis consectetur purus sit amet fermentum.</p>
|
|
<p>
|
|
<button type="button" class="btn btn-danger">Take this action</button>
|
|
<button type="button" class="btn btn-secondary">Or do this</button>
|
|
</p>
|
|
</div>
|
|
{% endexample %}
|
|
|
|
## 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. Closing an alert removes it from the DOM.
|
|
|
|
{% highlight html %}
|
|
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
|
|
<span aria-hidden="true">×</span>
|
|
<span class="sr-only">Close</span>
|
|
</button>
|
|
{% endhighlight %}
|
|
|
|
To have your alerts use animation when closing, make sure they have the `.fade` and `.in` classes already applied to them.
|
|
|
|
### Methods
|
|
|
|
#### $().alert()
|
|
|
|
Makes an alert listen for click events on descendant elements which have the `data-dismiss="alert"` attribute. (Not necessary when using the data-api's auto-initialization.)
|
|
|
|
#### $().alert('close')
|
|
|
|
Closes an alert by removing it from the DOM. If the `.fade` and `.in` classes are present on the element, the alert will fade out before it is removed.
|
|
|
|
{% highlight js %}$(".alert").alert('close'){% endhighlight %}
|
|
|
|
### Events
|
|
|
|
Bootstrap's alert plugin 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 %}
|
|
$('#myAlert').on('closed.bs.alert', function () {
|
|
// do something…
|
|
})
|
|
{% endhighlight %}
