# Modals bootstrap-modal.js

Our Modal plugin is a super slim take on the traditional modal js plugin, taking special care to include only the bare functionality that we require here at twitter.

Download

### Using bootstrap-modal

    $('#my-modal').modal(options)

### Options

Name | type | default | description
--- | --- | --- | ---
backdrop | boolean, string | false | Includes a modal-backdrop element. Set backdrop to `"static"` if you do not want the modal closed when the backdrop is clicked.
keyboard | boolean | false | Closes the modal when escape key is pressed
show | boolean | false | Opens modal on class initialization

### Markup

You can activate modals on your page easily without having to write a single line of javascript. Just give an element a `data-controls-modal` attribute which corresponds to a modal element id, and when clicked, it will launch your modal. To add modal options, just include them as data attributes as well.

    <a class="btn" data-controls-modal="my-modal" data-backdrop="static" >Launch Modal</a>

Notice If you want your modal to animate in and out, just add a `.fade` class to your `.modal` element (refer to the demo to see this in action).

### Methods

#### .modal(options)

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

    $('#my-modal').modal({
      keyboard: true
    })

#### .modal('toggle')

Manually toggles a modal.

    $('#my-modal').modal('toggle')

#### .modal('show')

Manually opens a modal.

    $('#my-modal').modal('show')

#### .modal('hide')

Manually hides a modal.

    $('#my-modal').modal('hide')

#### .modal(true)

Returns an elements modal class instance.

    $('#my-modal').modal(true)

Notice Alternatively, this can be retrieved with `$().data('modal')`.

### 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).

    $('#my-modal').bind('hidden', function () {
      // do something ...
    })

# Dropdown bootstrap-dropdown.js

Download

### Using bootstrap-dropdown.js

    $('#topbar').dropdown()

### Markup

To quickly add dropdown functionality to any nav element, use the `data-dropdown` attribute. Any valid bootstrap dropdown will automatically be activated.

    <ul class="tabs">
      <li class="active"><a href="#">Home</a></li>
      <li class="dropdown" data-dropdown="dropdown" >
        <a href="#" class="dropdown-toggle">Dropdown</a>
        <ul class="dropdown-menu">
          <li><a href="#">Secondary link</a></li>
          <li><a href="#">Something else here</a></li>
          <li class="divider"></li>
          <li><a href="#">Another link</a></li>
        </ul>
      </li>
    </ul>

# ScrollSpy bootstrap-scrollspy.js

This plugin is for adding the scrollspy (auto updating nav) interaction to the bootstrap topbar.

Download

## Using bootstrap-scrollspy.js

    $('#topbar').scrollSpy()

### Markup

To easily add scrollspy behavior to your nav, just add the `data-scrollspy` attribute to the `.topbar`.

    <div class="topbar" data-scrollspy="scrollspy" >...</div>

### Methods

#### $().scrollSpy()

Auto activates navigation buttons by users scroll position.

    $('body > .topbar').scrollSpy()

Notice Topbar 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>`.

#### .scrollSpy('refresh')

The scrollspy caches nav buttons and section coordinates for performance. If you need to update this cache (likely if you have dynamic content) just call this refresh method. If you used the data attribute to define your scrollspy, just call refresh on the body.

    $('body').scrollSpy('refresh')

### Demo

Checkout the the topbar navigation on this page.

Notice You can enable auto toggling of a button by using the `data-toggle` attribute.

    <button class="btn" data-toggle="toggle" >...</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>

#### $().button('reset')

Resets button state - swaps text to original text.

#### $().button(string)

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

# Tabs bootstrap-tabs.js

### Using bootstrap-tabs.js

     <ul class="tabs" data-tabs="tabs" >...</ul>

### Methods
