Javascript for Bootstrap

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

Getting started

Integrating javascript with the Bootstrap library is super easy. Here we go over the basics and provide you with some awesome plugins to get you started!

What's included

Bring some of Bootstrap's primary components to life with custom jQuery plugins. We encourage you to extend and modify them to fit your specific development needs.

File Description
bootstrap-transition.js The transition plugin is required for adding animation to other bootstrap plugins. Include this plugin (only once) when sliding in modals or fading out alerts.
bootstrap-modal.js Our Modal plugin is a super slim take on the traditional modal js plugin! We took special care to include only the bare functionality that we require here at twitter.
bootstrap-dropdown.js This plugin is for adding generic dropdown interactions to things like navigation top bars and tabs.
bootstrap-scrollspy.js The ScrollSpy plugin is for automatically updating nav targets based on scroll position.
bootstrap-tab.js This plugin adds quick, dynamic tab and pill functionality for transitioning through local content.
bootstrap-twipsy.js Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; twipsy is an updated version, which doesn't rely on images, uses css3 for animations, data-attributes for local title storage, and now jquery 1.7's new event api!
bootstrap-popover.js The popover plugin provides a simple interface for adding popovers to your application. It extends the bootstrap-twipsy.js plugin, so be sure to grab that file as well when including popovers in your project!
bootstrap-alert.js The alert plugin is a tiny class for adding close functionality to alerts.
bootstrap-button.js This plugin offers additional functionality for managing button state in single buttons and button sets.
bootstrap-collapse.js The collapse plugin offers simple, generic collapsible element support for making accordions and other collapsible ui components.

Is javascript necessary?

Nope! Bootstrap is designed first and foremost to be a CSS library. This javascript provides a basic interactive layer on top of the included styles.

However, for those who do need javascript, we've provided the plugins above to help you understand how to integrate Bootstrap with javascript and to give you a quick, lightweight option for the basic functionality right away.

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

Download

Using bootstrap-scrollspy.js

$('#navbar').dropdown()

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>

Notice Navbar anchor tags 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>.

Demo

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

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

Download

Using bootstrap-tab.js

$('#myTab').tab('show')

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.

<ul class="tabs">
  <li><a href="#home" data-toggle="tab">Home</a></li>
  <li><a href="#profile" data-toggle="tab">Profile</a></li>
  <li><a href="http://twitter.com/fat">twitter</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="tabs">
  <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="pill-content">
  <div class="active" id="home">...</div>
  <div id="profile">...</div>
  <div id="messages">...</div>
  <div id="settings">...</div>
</div>

<script>
  $(function () {
    $('.tabs 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
})
