Modals modal.js
Examples
Live demo
Toggle a modal via JavaScript by clicking the button below. It will slide down and fade in from the top of the page.
<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->
Make modals accessible
Be sure to add role="dialog" to .modal, aria-labelledby="myModalLabel" attribute to reference the modal title, and aria-hidden="true" to tell assistive technologies to skip the modal's DOM elements.
Additionally, you may give a description of your modal dialog with aria-describedby on .modal.
Usage
Via data attributes
Activate a modal without writing JavaScript. Set data-toggle="modal" on a controller element, like a button, along with a data-target="#foo" or href="#foo" to target a specific modal to toggle.

Via JavaScript
Call a modal with id myModal with a single line of JavaScript:
$('#myModal').modal(options)
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-backdrop="".
| Name | type | default | description |
|---|---|---|---|
| backdrop | boolean | true | Includes a modal-backdrop element. Alternatively, specify static for a backdrop which doesn't close the modal on click. |
| keyboard | boolean | true | Closes the modal when escape key is pressed |
| show | boolean | true | Shows the modal when initialized. |
| remote | path | false | If a remote URL is provided, content will be loaded via jQuery's |

Extends tabbed navigation
This plugin extends the tabbed navigation component to add tabbable areas.
Usage
Enable tabbable tabs via JavaScript (each tab needs to be activated individually):
$('#myTab a').click(function (e) {
e.preventDefault()
$(this).tab('show')
})
You can activate individual tabs in several ways:
$('#myTab a[href="#profile"]').tab('show') // Select tab by name
$('#myTab a:first').tab('show') // Select first tab
$('#myTab a:last').tab('show') // Select last tab
$('#myTab li:eq(2) a').tab('show') // Select third tab (0-indexed)
Markup
You can activate a tab or pill navigation without writing any JavaScript by simply specifying data-toggle="tab" or data-toggle="pill" on an element. Adding the nav and nav-tabs classes to the tab ul will apply the Bootstrap tab styling.
<!-- Nav tabs -->
<ul class="nav nav-tabs">
<li><a href="#home" data-toggle="tab">Home</a></li>
<li><a href="#profile" data-toggle="tab">Profile</a></li>
<li><a href="#messages" data-toggle="tab">Messages</a></li>
<li><a href="#settings" data-toggle="tab">Settings</a></li>
</ul>
<!-- Tab panes -->
<div class="tab-content">
<div class="tab-pane active" id="home">...</div>
<div class="tab-pane" id="profile">...</div>
<div class="tab-pane" id="messages">...</div>
<div class="tab-pane" id="settings">...</div>
</div>
Fade effect
To make tabs fade in, add .fade to each .tab-pane. The first tab pane must also have .in to properly fade in initial content.
<div class="tab-content">
<div class="tab-pane fade in active" id="home">...</div>
<div class="tab-pane fade" id="profile">...</div>
<div class="tab-pane fade" id="messages">...</div>
<div class="tab-pane fade" id="settings">...</div>
</div>
Methods
$().tab
Activates a tab element and content container. Tab should have either a data-target or an href targeting a container node in the DOM.
<ul class="nav nav-tabs" id="myTab">
<li class="active"><a href="#home">Home</a></li>
<li><a href="#profile">Profile</a></li>
<li><a href="#messages">Messages</a></li>
<li><a href="#settings">Settings</a></li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="home">...</div>
<div class="tab-pane" id="profile">...</div>
<div class="tab-pane" id="messages">...</div>
<div class="tab-pane" id="settings">...</div>
</div>
<script>
$(function () {
$('#myTab a:last').tab('show')
})
</script>
Events
| Event Type | Description |
|---|---|
| show.bs.tab | This event fires on tab show, but before the new tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively. |
| shown.bs.tab | This event fires on tab show after a tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively. |
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
e.target // activated tab
e.relatedTarget // previous tab
})

You can also use the plugin without the accordion markup. Make a button toggle the expanding and collapsing of another element.
<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo">
simple collapsible
</button>
<div id="demo" class="collapse in">...</div>
Usage
Via data attributes
Just add data-toggle="collapse" and a data-target to element to automatically assign control of a collapsible element. The data-target attribute accepts a CSS selector to apply the collapse to. Be sure to add the class collapse to the collapsible element. If you'd like it to default open, add the additional class in.
To add accordion-like group management to a collapsible control, add the data attribute data-parent="#selector". Refer to the demo to see this in action.
Via JavaScript
Enable manually with:
$(".collapse").collapse()
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-parent="".
| Name | type | default | description |
|---|---|---|---|
| parent | selector | false | If selector then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this dependent on the accordion-group class) |
| toggle | boolean | true | Toggles the collapsible element on invocation |
Methods
.collapse(options)
Activates your content as a collapsible element. Accepts an optional options object.
$('#myCollapsible').collapse({
toggle: false
})
.collapse('toggle')
Toggles a collapsible element to shown or hidden.
.collapse('show')
Shows a collapsible element.
.collapse('hide')
Hides a collapsible element.
Events
Bootstrap's collapse class exposes a few events for hooking into collapse functionality.
| Event Type | Description |
|---|---|
| show.bs.collapse | This event fires immediately when the show instance method is called. |
| shown.bs.collapse | This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.collapse |
This event is fired immediately when the hide method has been called.
|
| hidden.bs.collapse | This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete). |
$('#myCollapsible').on('hidden.bs.collapse', function () {
// do something…
})
Carousel carousel.js
Examples
The slideshow below shows a generic plugin and component for cycling through elements like a carousel.
<div id="carousel-example-generic" class="carousel slide">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
<li data-target="#carousel-example-generic" data-slide-to="1"></li>
<li data-target="#carousel-example-generic" data-slide-to="2"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner">
<div class="item active">
<img src="..." alt="...">
<div class="carousel-caption">
...
</div>
</div>
...
</div>
<!-- Controls -->
<a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
Transition animations not supported in Internet Explorer 8 & 9
Bootstrap exclusively uses CSS3 for its animations, but Internet Explorer 8 & 9 don't support the necessary CSS properties. Thus, there are no slide transition animations when using these browsers. We have intentionally decided not to include jQuery-based fallbacks for the transitions.
Optional captions
Add captions to your slides easily with the .carousel-caption element within any .item. Place just about any optional HTML within there and it will be automatically aligned and formatted.
<div class="item active">
<img src="..." alt="...">
<div class="carousel-caption">
<h3>...</h3>
<p>...</p>
</div>
</div>
Accessibility issue
The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.
Please visit http://shouldiuseacarousel.com/ for more details
Usage
Via data attributes
Use data attributes to easily control the position of the carousel. data-slide accepts the keywords prev or next, which alters the slide position relative to its current position. Alternatively, use data-slide-to to pass a raw slide index to the carousel data-slide-to="2", which shifts the slide position to a particular index beginning with 0.
The data-ride="carousel" attribute is used to mark a carousel as animating starting at page load.
Via JavaScript
Call carousel manually with:
$('.carousel').carousel()
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-interval="".
| Name | type | default | description |
|---|---|---|---|
| interval | number | 5000 | The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle. |
| pause | string | "hover" | Pauses the cycling of the carousel on mouseenter and resumes the cycling of the carousel on mouseleave. |
| wrap | boolean | true | Whether the carousel should cycle continuously or have hard stops. |
Methods
.carousel(options)
Initializes the carousel with an optional options object and starts cycling through items.
$('.carousel').carousel({
interval: 2000
})
.carousel('cycle')
Cycles through the carousel items from left to right.
.carousel('pause')
Stops the carousel from cycling through items.
.carousel(number)
Cycles the carousel to a particular frame (0 based, similar to an array).
.carousel('prev')
Cycles to the previous item.
.carousel('next')
Cycles to the next item.
Events
Bootstrap's carousel class exposes two events for hooking into carousel functionality.
| Event Type | Description |
|---|---|
| slide.bs.carousel | This event fires immediately when the slide instance method is invoked. |
| slid.bs.carousel | This event is fired when the carousel has completed its slide transition. |
$('#myCarousel').on('slide.bs.carousel', function () {
// do something…
})
