Javascript for Bootstrap

Bring Bootstrap's components to life—now with 12 custom jQuery plugins.

Individual or compiled

If you have downloaded the latest version of Bootstrap, both bootstrap.js and bootstrap.min.js contain all of these plugins.

About transitions

For simple transition effects, include bootstrap-transition.js once alongside the other JS files. If you're using the compiled (or minified) bootstrap.js, there is no need to include this—it's already there.

Use cases

A few examples of the transition plugin:

About modals

A streamlined, but flexible, take on the traditional javascript modal plugin with only the minimum required functionality and smart defaults.

Static example

<div class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">&times;</button>
    <h3>Modal header</h3>
  </div>
  <div class="modal-body">
    <p>One fine body…</p>
  </div>
  <div class="modal-footer">
    <a href="#" class="btn">Close</a>
    <a href="#" class="btn btn-primary">Save changes</a>
  </div>
</div>

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.


Usage

Call the modal via javascript:

$('#myModal').modal(options)

Options

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 load method and injected into the .modal-body. If you're using the data api, you may alternatively use the href tag to specify the remote source. An example of this is shown below:

<a data-toggle="modal" href="remote.html" data-target="#modal">click me</a>

Markup

You can activate modals on your page easily without having to write a single line of javascript. Just set data-toggle="modal" on a controller element with a data-target="#foo" or href="#foo" which corresponds to a modal element id, and when clicked, it will launch your modal.

Also, to add options to your modal instance, just include them as additional data attributes on either the control element or the modal markup itself.

<a href="#myModal" role="button" class="btn" data-toggle="modal">Launch Modal</a>
<div class="modal" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">×</button>
    <h3 id="myModalLabel">Modal header</h3>
  </div>
  <div class="modal-body">
    <p>One fine body…</p>
  </div>
  <div class="modal-footer">
    <a href="#" role="button" class="btn">Close</a>
    <a href="#" role="button" class="btn btn-primary">Save changes</a>
  </div>
</div>
Heads up! If you want your modal to animate in and out, just add a .fade class to the .modal element (refer to the demo to see this in action) and include bootstrap-transition.js.

Methods

.modal(options)

Activates your content as a modal. Accepts an optional options object.

$('#myModal').modal({
  keyboard: false
})

.modal('toggle')

Manually toggles a modal.

$('#myModal').modal('toggle')

.modal('show')

Manually opens a modal.

$('#myModal').modal('show')

.modal('hide')

Manually hides a modal.

$('#myModal').modal('hide')

Events

Bootstrap's modal class exposes a few events for hooking into modal functionality.

Event Description
show This event fires immediately when the show instance method is called.
shown This event is fired when the modal has been made visible to the user (will wait for css transitions to complete).
hide This event is fired immediately when the hide instance method has been called.
hidden This event is fired when the modal has finished being hidden from the user (will wait for css transitions to complete).
$('#myModal').on('hidden', function () {
  // do something…
})

The ScrollSpy plugin is for automatically updating nav targets based on scroll position.

Example navbar with scrollspy

Scroll the area below and watch the navigation update. The dropdown sub items will be highlighted as well. Try it!

Using bootstrap-scrollspy.js

Call the scrollspy via javascript:

$('#navbar').scrollspy()

Markup

To easily add scrollspy behavior to your topbar navigation, just add data-spy="scroll" to the element you want to spy on (most typically this would be the body).

<body data-spy="scroll" >...</body>
Heads up! Navbar links must have resolvable id targets. For example, a <a href="#home">home</a> must correspond to something in the dom like <div id="home"></div>.

Methods

.scrollspy('refresh')

When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so:

$('[data-spy="scroll"]').each(function () {
  var $spy = $(this).scrollspy('refresh')
});

Options

Name type default description
offset number 10 Pixels to offset from top when calculating position of scroll.

Events

Event Description
activate This event fires whenever a new item becomes activated by the scrollspy.

This plugin adds quick, dynamic tab and pill functionality for transitioning through local content.

Example tabs

Click the tabs below to toggle between hidden panes, even via dropdown menus.

Using bootstrap-tab.js

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.

<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>

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 Description
show 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 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', function (e) {
  e.target // activated tab
  e.relatedTarget // previous tab
})

About Tooltips

Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use css3 for animations, and data-attributes for local title storage.

Example use of Tooltips

Hover over the links below to see tooltips:

Tight pants next level keffiyeh you probably haven't heard of them. Photo booth beard raw denim letterpress vegan messenger bag stumptown. Farm-to-table seitan, mcsweeney's fixie sustainable quinoa 8-bit american apparel have a terry richardson vinyl chambray. Beard stumptown, cardigans banh mi lomo thundercats. Tofu biodiesel williamsburg marfa, four loko mcsweeney's cleanse vegan chambray. A really ironic artisan whatever keytar, scenester farm-to-table banksy Austin twitter handle freegan cred raw denim single-origin coffee viral.

Using bootstrap-tooltip.js

Trigger the tooltip via javascript:

$('#example').tooltip(options)

Options

Name type default description
animation boolean true apply a css fade transition to the tooltip
html boolean true Insert html into the tooltip. If false, jquery's text method will be used to insert content into the dom. Use text if you're worried about XSS attacks.
placement string|function 'top' how to position the tooltip - top | bottom | left | right
selector string false If a selector is provided, tooltip objects will be delegated to the specified targets.
title string | function '' default title value if `title` tag isn't present
trigger string 'hover' how tooltip is triggered - hover | focus | manual
delay number | object 0

delay showing and hiding the tooltip (ms) - does not apply to manual trigger type

If a number is supplied, delay is applied to both hide/show

Object structure is: delay: { show: 500, hide: 100 }

Heads up! Options for individual tooltips can alternatively be specified through the use of data attributes.

Markup

For performance reasons, the Tooltip and Popover data-apis are opt in. If you would like to use them just specify a selector option.

<a href="#" rel="tooltip" title="first tooltip">hover over me</a>

Methods

$().tooltip(options)

Attaches a tooltip handler to an element collection.

.tooltip('show')

About alerts

The alert plugin is a tiny class for adding close functionality to alerts.

Example alerts

The alerts plugin works on regular alert messages, and block messages.

Holy guacamole! Best check yo self, you're not looking too good.

Oh snap! You got an error!

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.

Take this action Or do this

Using bootstrap-alert.js

Enable dismissal of an alert via javascript:

$(".alert").alert()

Markup

Just add data-dismiss="alert" to your close button to automatically give an alert close functionality.

<a class="close" data-dismiss="alert" href="#">&times;</a>

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.

$(".alert").alert('close')

Events

Bootstrap's alert class exposes a few events for hooking into alert functionality.

Event Description
close This event fires immediately when the close instance method is called.
closed This event is fired when the alert has been closed (will wait for css transitions to complete).
$('#my-alert').bind('closed', function () {
  // do something…
})

About

Do more with buttons. Control button states or create groups of buttons for more components like toolbars.

Example uses

Use the buttons plugin for states and toggles.

Stateful

Single toggle

Checkbox

Radio

Using bootstrap-button.js

Enable buttons via javascript:

$('.nav-tabs').button()

Markup

Data attributes are integral to the button plugin. Check out the example code below for the various markup types.

<!-- Add data-toggle="button" to activate toggling on a single button -->
<button class="btn" data-toggle="button">Single Toggle</button>

<!-- Add data-toggle="buttons-checkbox" for checkbox style toggling on btn-group -->
<div class="btn-group" data-toggle="buttons-checkbox">
  <button class="btn">Left</button>
  <button class="btn">Middle</button>
  <button class="btn">Right</button>
</div>

<!-- Add data-toggle="buttons-radio" for radio style toggling on btn-group -->
<div class="btn-group" data-toggle="buttons-radio">
  <button class="btn">Left</button>
  <button class="btn">Middle</button>
  <button class="btn">Right</button>
</div>

Methods

$().button('toggle')

Toggles push state. Gives the button the appearance that it has been activated.

Heads up! You can enable auto toggling of a button by using the data-toggle attribute.
<button class="btn" data-toggle="button" >…</button>

$().button('loading')

Sets button state to loading - disables button and swaps text to loading text. Loading text should be defined on the button element using the data attribute data-loading-text.

<button class="btn" data-loading-text="loading stuff..." >...</button>
Heads up! Firefox persists the disabled state across page loads. A workaround for this is to use autocomplete="off".

$().button('reset')

Resets button state - swaps text to original text.

$().button(string)

Resets button state - swaps text to any data defined text state.

<button class="btn" data-complete-text="finished!" >...</button>
<script>
  $('.btn').button('complete')
</script>
