# JavaScript in Bootstrap

### Individual or compiled

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.

### Data attributes

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')

### Programmatic API

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')`.

### No conflict

Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call `.noConflict` on the plugin you wish to revert the value of.

    var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
    $.fn.bootstrapBtn = bootstrapButton            // give $().bootstrapBtn the bootstrap functionality

### Events

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 ability 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
    })

# Transitions bootstrap-transition.js

### 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:

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

# Modals bootstrap-modal.js

## Examples

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

### Static example

A rendered modal with header, body, and set of actions in the footer.

### Modal header

One fine body…

    <div class="modal fade">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&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.

### Modal Heading

#### Text in a modal

Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem.

#### Popover in a modal

This button should trigger a popover on click.

#### Tooltips in a modal

This link and that link should have tooltips on hover.

#### Overflowing text to show optional scrollbar

We set a fixed `max-height` on the `.modal-body`. Watch it overflow with all this extra lorem ipsum text we've included.

Cras mattis consectetur purus sit amet fermentum. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Morbi leo risus, porta ac consectetur ac, vestibulum at eros.

Praesent commodo cursus magna, vel scelerisque nisl consectetur et. Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor.

Aenean lacinia bibendum nulla sed consectetur. Praesent commodo cursus magna, vel scelerisque nisl consectetur et. Donec sed odio dui. Donec ullamcorper nulla non metus auctor fringilla.

Cras mattis consectetur purus sit amet fermentum. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Morbi leo risus, porta ac consectetur ac, vestibulum at eros.

Praesent commodo cursus magna, vel scelerisque nisl consectetur et. Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor.

Aenean lacinia bibendum nulla sed consectetur. Praesent commodo cursus magna, vel scelerisque nisl consectetur et. Donec sed odio dui. Donec ullamcorper nulla non metus auctor fringilla.

Launch demo modal

    <!-- Button to trigger modal -->
    <a href="#myModal" role="button" class="btn" data-toggle="modal">Launch demo modal</a>

    <!-- Modal -->
    <div id="myModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h3 id="myModalLabel">Modal header</h3>
      </div>
      <div class="modal-body">
        <p>One fine body…</p>
      </div>
      <div class="modal-footer">
        <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
        <button class="btn btn-primary">Save changes</button>
      </div>
    </div>

## 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.

    <button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>

### 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 `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>

### 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…
    })

# Dropdowns bootstrap-dropdown.js

## Examples

Add dropdown menus to nearly anything with this simple plugin, including the navbar, tabs, and pills.

### Within a navbar

### Within tabs

## Usage

### Via data attributes

Add `data-toggle="dropdown"` to a link or button to toggle a dropdown.

    <div class="dropdown">
      <a class="dropdown-toggle" data-toggle="dropdown" href="#">Dropdown trigger</a>
      <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
        ...
      </ul>
    </div>

To keep URLs intact, use the `data-target` attribute instead of `href="#"`.

    <div class="dropdown">
      <a class="dropdown-toggle" id="dLabel" role="button" data-toggle="dropdown" data-target="#" href="/page.html">
        Dropdown
        <b class="caret"></b>
      </a>
      <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
        ...
      </ul>
    </div>

### Via JavaScript

Call the dropdowns via JavaScript:

    $('.dropdown-toggle').dropdown()

### Options

None

### Methods

#### $().dropdown('toggle')

A programmatic api for toggling menus for a given navbar or tabbed navigation.

# ScrollSpy bootstrap-scrollspy.js

## Example in navbar

The ScrollSpy plugin is for automatically updating nav targets based on scroll position. Scroll the area below the navbar and watch the active class change. The dropdown sub items will be highlighted as well.

## Usage

### Via data attributes

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>

### Via JavaScript

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>`.

### 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

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

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.

# Togglable tabs bootstrap-tab.js

## 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.

    <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>

To make tabs fade in, add `.fade` to each `.tab-pane`.

### 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
    })

# Tooltips bootstrap-tooltip.js

## Examples

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.

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.

A really ironic artisan whatever keytar, scenester farm-to-table banksy Austin twitter handle freegan cred raw denim single-origin coffee viral.

### Four directions

- Tooltip on top
- Tooltip on right
- Tooltip on bottom
- Tooltip on left

## Usage

Trigger the tooltip via JavaScript:

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

### Options

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

Name | type | default | description
--- | --- | --- | ---
animation | boolean | true | apply a css fade transition to the tooltip
html | boolean | false | 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 focus' | how tooltip is triggered - click | hover | focus | manual. Note you case pass trigger mutliple, space seperated, trigger types.
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 }`
container | string | false | false | Appends the tooltip to a specific element `container: 'body'`

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

### Markup

    <a href="#" data-toggle="tooltip" title="first tooltip">hover over me</a>

### Methods

#### $().tooltip(options)

Attaches a tooltip handler to an element collection.

#### .tooltip('show')

Reveals an element's tooltip.

    $('#element').tooltip('show')

#### .tooltip('hide')

Hides an element's tooltip.

    $('#element').tooltip('hide')

#### .tooltip('toggle')

Toggles an element's tooltip.

    $('#element').tooltip('toggle')

#### .tooltip('destroy')

Hides and destroys an element's tooltip.

    $('#element').tooltip('destroy')

# Popovers bootstrap-popover.js

## Examples

Add small overlays of content, like those on the iPad, to any element for housing secondary information. Hover over the button to trigger the popover. Requires Tooltip to be included.

### Static popover

Four options are available: top, right, bottom, and left aligned.

### Popover top

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

### Popover right

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

### Popover bottom

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

### Popover left

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

No markup shown as popovers are generated from JavaScript and content within a `data` attribute.

### Live demo

Click to toggle popover

#### Four directions

- Popover on top
- Popover on right
- Popover on bottom
- Popover on left

## Usage

Enable popovers via JavaScript:

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

### Options

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

Name | type | default | description
--- | --- | --- | ---
animation | boolean | true | apply a css fade transition to the tooltip
html | boolean | false | Insert html into the popover. 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 | 'right' | how to position the popover - top | bottom | left | right
selector | string | false | if a selector is provided, tooltip objects will be delegated to the specified targets
trigger | string | 'click' | how popover is triggered - click | hover | focus | manual
title | string | function | '' | default title value if `title` attribute isn't present
content | string | function | '' | default content value if `data-content` attribute isn't present
delay | number | object | 0 | delay showing and hiding the popover (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 popovers 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.

### Methods

# Alert messages bootstrap-alert.js

## Example alerts

Add dismiss functionality to all alert messages with this plugin.

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

## Usage

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…
    })

# Buttons bootstrap-button.js

## Example uses

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

#### Stateful

Add `data-loading-text="Loading..."` to use a loading state on a button.

    <button type="button" class="btn btn-primary" data-loading-text="Loading...">Loading state</button>

#### Single toggle

Add `data-toggle="button"` to activate toggling on a single button.

    <button type="button" class="btn btn-primary" data-toggle="button">Single Toggle</button>

#### Checkbox

Add `data-toggle="buttons-checkbox"` for checkbox style toggling on btn-group.

    <div class="btn-group" data-toggle="buttons-checkbox">
      <button type="button" class="btn btn-primary">Left</button>
      <button type="button" class="btn btn-primary">Middle</button>
      <button type="button" class="btn btn-primary">Right</button>
    </div>

#### Radio

Add `data-toggle="buttons-radio"` for radio style toggling on btn-group.

    <div class="btn-group" data-toggle="buttons-radio">
      <button type="button" class="btn btn-primary">Left</button>
      <button type="button" class="btn btn-primary">Middle</button>
      <button type="button" class="btn btn-primary">Right</button>
    </div>

## Usage

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.

### Options

None

### 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 type="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 type="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 type="button" class="btn" data-complete-text="finished!" >...</button>

# Collapse bootstrap-collapse.js

### About

Get base styles and flexible support for collapsible components like accordions and navigation.

* Requires the Transitions plugin to be included.

## Example accordion

Using the collapse plugin, we built a simple accordion style widget:

Collapsible Group Item #1

    <div class="accordion" id="accordion2">
      <div class="accordion-group">
        <div class="accordion-heading">
          <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseOne">
            Collapsible Group Item #1
          </a>
        </div>
        <div id="collapseOne" class="accordion-body collapse in">
          <div class="accordion-inner">
            Anim pariatur cliche...
          </div>
        </div>
      </div>
      <div class="accordion-group">
        <div class="accordion-heading">
          <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseTwo">
            Collapsible Group Item #2
          </a>
        </div>
        <div id="collapseTwo" class="accordion-body collapse">
          <div class="accordion-inner">
            Anim pariatur cliche...
          </div>
        </div>
      </div>
    </div>
    ...

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)
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 | Description
--- | ---
show | This event fires immediately when the `show` instance method is called.
shown | This event is fired when a collapse element has been made visible to the user (will wait for css transitions to complete).
hide | This event is fired immediately when the `hide` method has been called.
hidden | This event is fired when a collapse element has been hidden from the user (will wait for css transitions to complete).

    $('#myCollapsible').on('hidden', function () {
      // do something…
    })

# Carousel bootstrap-carousel.js

## Example carousel

The slideshow below shows a generic plugin and component for cycling through elements like a carousel.

### First slide label

Nulla vitae elit libero, a pharetra augue. Maecenas faucibus mollis interdum. Cum sociis natoque penatibus et magnis dis parturient montes.

### Second slide label

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean lacinia bibendum nulla sed consectetur. Nullam quis risus eget urna mollis ornare.

### Third slide label

Praesent commodo cursus magna, vel scelerisque nisl consectetur et. Integer posuere erat a ante venenatis dapibus posuere velit aliquet.

‹ ›

    <div id="myCarousel" class="carousel slide">
      <ol class="carousel-indicators">
        <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
        <li data-target="#myCarousel" data-slide-to="1"></li>
        <li data-target="#myCarousel" data-slide-to="2"></li>
      </ol>
      <!-- Carousel items -->
      <div class="carousel-inner">
        <div class="active item">…</div>
        <div class="item">…</div>
        <div class="item">…</div>
      </div>
      <!-- Carousel nav -->
      <a class="carousel-control left" href="#myCarousel" data-slide="prev">&lsaquo;</a>
      <a class="carousel-control right" href="#myCarousel" data-slide="next">&rsaquo;</a>
    </div>

Heads up! When implementing this carousel, remove the images we have provided and replace them with your own.

## 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 it's current position. Alternatively, use `data-slide-to` to pass a raw slide index to the carousel `data-slide-to="2"`, which jump's the slide position to a particular index beginning with `0`.

### 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.

### 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 | Description
--- | ---
slide | This event fires immediately when the `slide` instance method is invoked.
slid | This event is fired when the carousel has completed its slide transition.

# Typeahead bootstrap-typeahead.js

## Example

A basic, easily extended plugin for quickly creating elegant typeaheads with any form text input.

    <input type="text" data-provide="typeahead">

You'll want to set `autocomplete="off"` to prevent default browser menus from appearing over the Bootstrap typeahead dropdown.

## Usage

### Via data attributes

Add data attributes to register an element with typeahead functionality as shown in the example above.

### Via JavaScript

Call the typeahead manually with:

    $('.typeahead').typeahead()

### Options

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

Name | type | default | description
--- | --- | --- | ---
source | array, function | [ ] | The data source to query against. May be an array of strings or a function. The function is passed two arguments, the `query` value in the input field and the `process` callback. The function may be used synchronously by returning the data source directly or asynchronously via the `process` callback's single argument.
items | number | 8 | The max number of items to display in the dropdown.
minLength | number | 1 | The minimum character length needed before triggering autocomplete suggestions
matcher | function | case insensitive | The method used to determine if a query matches an item. Accepts a single argument, the `item` against which to test the query. Access the current query with `this.query`. Return a boolean `true` if query is a match.
sorter | function | exact match, case sensitive, case insensitive | Method used to sort autocomplete results. Accepts a single argument `items` and has the scope of the typeahead instance. Reference the current query with `this.query`.
updater | function | returns selected item | The method used to return selected item. Accepts a single argument, the `item` and has the scope of the typeahead instance.
highlighter | function | highlights all default matches | Method used to highlight autocomplete results. Accepts a single argument `item` and has the scope of the typeahead instance. Should return html.

### Methods

#### .typeahead(options)

Initializes an input with a typeahead.

# Affix bootstrap-affix.js

## Example

The subnavigation on the left is a live demo of the affix plugin.

## Usage

### Via data attributes

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.

### Via JavaScript

Call the affix plugin via JavaScript:

    $('#navbar').affix()

### Methods

#### .affix('refresh')

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

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

Name | type | default | description
--- | --- | --- | ---
offset | number | function | object | 10 | Pixels to offset from screen when calculating position of scroll. If a single number is provided, the offset will be applied in both top and left directions. To listen for a single direction, or multiple unique offsets, just provide an object `offset: { x: 10 }`. Use a function when you need to dynamically provide an offset (useful for some responsive designs).
