Plugins can be included individually (though some have required dependencies), or all at once. Both bootstrap.js and bootstrap.min.js contain all plugins in a single file.

WWW33372COM

You can use all Bootstrap plugins purely through the markup API without writing a single line of JavaScript. This is Bootstrap's first class API and should be your first consideration when using a plugin.

That said, in some situations it may be desirable to turn this functionality off. Therefore, we also provide the ability to disable the data attribute API by unbinding all events on the body namespaced with `'data-api'`. This looks like this:

$('body').off('.data-api')

Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:

$('body').off('.alert.data-api')

WWWCCTV116COM

We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.

$(".btn.danger").button("toggle").addClass("fat")

All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):

$("#myModal").modal()                       // initialized with defaults
$("#myModal").modal({ keyboard: false })   // initialized with no keyboard
$("#myModal").modal('show')                // initializes and invokes show immediately

Each plugin also exposes its raw constructor on a `Constructor` property: $.fn.popover.Constructor. If you'd like to get a particular plugin instance, retrieve it directly from an element: $('[rel=popover]').data('popover').

WWWGH0007COM

Bootstrap provides custom events for most plugin's unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. show) is triggered at the start of an event, and its past participle form (ex. shown) is trigger on the completion of an action.

All infinitive events provide preventDefault functionality. This provides the abililty to stop the execution of an action before it starts.

$('#myModal').on('show', function (e) {
    if (!data) return e.preventDefault() // stops modal from being shown
})

WWWBET2090COM

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.

WWWK33K33COM

A few examples of the transition plugin:

  • Sliding or fading in modals
  • Fading out tabs
  • Fading out alerts
  • Sliding carousel panes

Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.

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) and data-target=".navbar" to select which nav to use. You'll want to use scrollspy with a .nav component.

<body data-spy="scroll" data-target=".navbar">...</body>

WWW332297COM

Call the scrollspy via JavaScript:

$('#navbar').scrollspy()
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>.

To easily add affix behavior to any element, just add data-spy="affix" to the element you want to spy on. Then use offsets to define when to toggle the pinning of an element on and off.

<div data-spy="affix" data-offset-top="200">...</div>
Heads up! You must manage the position of a pinned element and the behavior of its immediate parent. Position is controlled by affix, affix-top, and affix-bottom. Remember to check for a potentially collapsed parent when the affix kicks in as it's removing content from the normal flow of the page.

When using affix in conjunction with adding or removing of elements from the DOM, you'll want to call the refresh method:

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

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset-top="200".
