JavaScript 插件可以单个引入（使用 Bootstrap 提供的单个 *.js 文件），或者一次性全部引入（使用 bootstrap.js 或压缩版的 bootstrap.min.js）。
bootstrap.js 和 bootstrap.min.js 都包含了所有插件，你在使用时，只需选择一个引入页面就可以了。
不要在同一个元素上同时使用多个插件的 data 属性。例如，button 组件不能同时支持工具提示和控制模态框。如果需要的话，可以在其外面包裹一个额外的元素。
某些插件和 CSS 组件依赖于其它插件。如果你是单个引入每个插件的，请确保在文档中检查插件之间的依赖关系。注意，所有插件都依赖 jQuery （也就是说，jQuery必须在所有插件之前引入页面）。 bower.json 文件中列出了 Bootstrap 所支持的 jQuery 版本。
你可以仅仅通过 data 属性 API 就能使用所有的 Bootstrap 插件，无需写一行 JavaScript 代码。这是 Bootstrap 中的一等 API，也应该是你的首选方式。
话又说回来，在某些情况下可能需要将此功能关闭。因此，我们还提供了关闭 data 属性 API 的方法，即解除以 data-api 为命名空间并绑定在文档上的事件。就像下面这样：
$(document).off(‘.data-api‘)
另外，如果是针对某个特定的插件，只需在 data-api 前面添加那个插件的名称作为命名空间，如下：
$(document).off(‘.alert.data-api‘)
我们为所有 Bootstrap 插件提供了纯 JavaScript 方式的 API。所有公开的 API 都是支持单独或链式调用方式，并且返回其所操作的元素集合（注：和jQuery的调用形式一致）。
$(‘.btn.danger‘).button(‘toggle‘).addClass(‘fat‘)
所有方法都可以接受一个可选的 option 对象作为参数，或者一个代表特定方法的字符串，或者什么也不提供（在这种情况下，插件将会以默认值初始化）：
$(‘#myModal‘).modal() // 以默认值初始化
$(‘#myModal‘).modal({ keyboard: false }) // initialized with no keyboard
$(‘#myModal‘).modal(‘show‘) // 初始化后立即调用 show 方法
每个插件还通过 Constructor 属性暴露了其原始的构造函数：$.fn.popover.Constructor。如果你想获取某个插件的实例，可以直接通过页面元素获取：$(‘[rel="popover"]‘).data(‘popover‘)。
每个插件都可以通过修改其自身的 Constructor.DEFAULTS 对象从而改变插件的默认设置：
$.fn.modal.Constructor.DEFAULTS.keyboard = false // 将模态框插件的 `keyboard` 默认选参数置为 false
某些时候可能需要将 Bootstrap 插件与其他 UI 框架共同使用。在这种情况下，命名空间冲突随时可能发生。如果不幸发生了这种情况，你可以通过调用插件的 .noConflict 方法恢复其原始值。
var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
$.fn.bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality
Bootstrap 为大部分插件所具有的动作提供了自定义事件。一般来说，这些事件都有不定式和过去式两种动词的命名形式，例如，不定式形式的动词（例如 show）表示其在事件开始时被触发；而过去式动词（例如 shown ）表示在动作执行完毕之后被触发。
从 3.0.0 版本开始，所有 Bootstrap 事件的名称都采用命名空间方式。
所有以不定式形式的动词命名的事件都提供了 preventDefault 功能。这就赋予你在动作开始执行前将其停止的能力。
$(‘#myModal‘).on(‘show.bs.modal‘, function (e) {
if (!data) return e.preventDefault() // 阻止模态框的展示
})
Bootstrap 插件未对禁用 JavaScript 的浏览器提供补救措施。如果你对这种情况下的用户体验很关心的话，请添加<noscript> 标签向你的用户进行解释（并告诉他们如何启用 JavaScript），或者按照你自己的方式提供补救措施。
Bootstrap 官方不提供对第三方 JavaScript 工具库的支持，例如 Prototype 或 jQuery UI。除了 .noConflict 和为事件名称添加命名空间，还可能会有兼容性方面的问题，这就需要你自己来处理了。
对于简单的过渡效果，只需将 transition.js 和其它 JS 文件一起引入即可。如果你使用的是编译（或压缩）版的bootstrap.js 文件，就无需再单独将其引入了。
Transition.js 是针对 transitionEnd 事件的一个基本辅助工具，也是对 CSS 过渡效果的模拟。它被其它插件用来检测当前浏览器对是否支持 CSS 的过渡效果。
模态框经过了优化，更加灵活，以弹出对话框的形式出现，具有最小和最实用的功能集。
千万不要在一个模态框上重叠另一个模态框。要想同时支持多个模态框，需要自己写额外的代码来实现。
务必将模态框的 HTML 代码放在文档的最高层级内（也就是说，尽量作为 body 标签的直接子元素），以避免其他组件影响模态框的展现和/或功能。
这里提供了在移动设备上使用模态框有一些附加说明。请参考浏览器支持章节。
Due to how HTML5 defines its semantics, the autofocus HTML attribute has no effect in Bootstrap modals.
以下模态框包含了模态框的头、体和一组放置于底部的按钮。
<div class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<h4 class="modal-title">Modal title</h4>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->
点击下面的按钮即可通过 JavaScript 启动一个模态框。此模态框将从上到下、逐渐浮现到页面前。
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">

</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
务必为 .modal 添加 role="dialog" 属性，aria-labelledby="myModalLabel" 属性用于只想模态框的标题栏，aria-hidden="true" 用于通知辅助性工具略过模态框的 DOM元素。
另外，你还应该通过 aria-describedby 属性为模态框 .modal 添加描述性信息。
在模态框中嵌入 YouTube 视频需要增加一些额外的 JavaScript 代码，用于自动停止重放等功能，这些代码并没有在 Bootstrap 中提供。请参考这份发布在 Stack Overflow 上的文章。
模态框提供了两个可选尺寸，通过为 .modal-dialog 增加一个样式调整类实现。
<!-- Large modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-lg">Large modal</button>
<div class="modal fade bs-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
...
</div>
</div>
</div>
<!-- Small modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-sm">Small modal</button>
<div class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
<div class="modal-dialog modal-sm">
<div class="modal-content">
...
</div>
</div>
</div>
如果你不需要模态框弹出时的动画效果（淡入淡出效果），删掉 .fade 类即可。
<div class="modal" tabindex="-1" role="dialog" aria-labelledby="" aria-hidden="true">
...
</div>
通过 data 属性或 JavaScript 调用模态框插件，可以根据需要动态展示隐藏的内容。模态框弹出时还会为 <body> 元素添加 .modal-open 类，从而覆盖页面默认的滚动行为，并且还会自动生成一个 .modal-backdrop 元素用于提供一个可点击的区域，点击此区域就即可关闭模态框。
不需写 JavaScript 代码也可激活模态框。通过在一个起控制器作用的元素（例如：按钮）上添加 data-toggle="modal"属性，或者 data-target="#foo" 属性，再或者 href="#foo" 属性，用于指向被控制的模态框。
<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
只需一行 JavaScript 代码，即可通过元素的 id myModal 调用模态框：
$(‘#myModal‘).modal(options)
可以将选项通过 data 属性或 JavaScript 代码传递。对于 data 属性，需要将参数名称放到 data- 之后，例如 data-backdrop=""。
| 名称 | 类型 | 默认值 | 描述 |
|---|---|---|---|
| backdrop | boolean 或 字符串‘static‘ |
true | Includes a modal-backdrop element. Alternatively, specify static for a backdrop which doesn‘t close the modal on click. |
| keyboard | boolean | true | 键盘上的 esc 键被按下时关闭模态框。 |
| show | boolean | true | 模态框初始化之后就立即显示出来。 |
| remote | path | false |
This option is deprecated since v3.2.1 and will be removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself. 如果提供的是 URL，将利用 jQuery 的 Copy
|
将页面中的某块内容作为模态框激活。接受可选参数 object。
$(‘#myModal‘).modal({
keyboard: false
})
手动打开或关闭模态框。在模态框显示或隐藏之前返回到主调函数中（也就是，在触发 shown.bs.modal 或hidden.bs.modal 事件之前）。
$(‘#myModal‘).modal(‘toggle‘)
手动打开模态框。在模态框显示之前返回到主调函数中 （也就是，在触发 shown.bs.modal 事件之前）。
$(‘#myModal‘).modal(‘show‘)
手动隐藏模态框。在模态框隐藏之前返回到主调函数中 （也就是，在触发 hidden.bs.modal 事件之前）。
$(‘#myModal‘).modal(‘hide‘)
Bootstrap 的模态框类提供了一些事件用于监听并执行你自己的代码。
| 事件类型 | 描述 |
|---|---|
| show.bs.modal | show 方法调用之后立即触发该事件。如果是通过点击某个作为触发器的元素，则此元素可以通过事件的relatedTarget 属性进行访问。 |
| shown.bs.modal | 此事件在模态框已经显示出来（并且同时在 CSS 过渡效果完成）之后被触发。如果是通过点击某个作为触发器的元素，则此元素可以通过事件的 relatedTarget 属性进行访问。 |
| hide.bs.modal | hide 方法调用之后立即触发该事件。 |
| hidden.bs.modal | 此事件在模态框被隐藏（并且同时在 CSS 过渡效果完成）之后被触发。 |
| loaded.bs.modal | 从远端的数据源加载完数据之后触发该事件。 |
$(‘#myModal‘).on(‘hidden.bs.modal‘, function (e) {
// do something...
})
Add dropdown menus to nearly anything with this simple plugin, including the navbar, tabs, and pills.
Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the .openclass on the parent list item.
On mobile devices, opening a dropdown adds a .dropdown-backdrop as a tap area for closing dropdown menus when tapping outside the menu, a requirement for proper iOS support. This means that switching from an open dropdown menu to a different dropdown menu requires an extra tap on mobile.
Note: The data-toggle="dropdown" attribute is relied on for closing dropdown menus at an application level, so it‘s a good idea to always use it.
Add data-toggle="dropdown" to a link or button to toggle a dropdown.
<div class="dropdown">
<button id="dLabel" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown trigger
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
...
</ul>
</div>
To keep URLs intact with link buttons, use the data-target attribute instead of href="#".
<div class="dropdown">
<a id="dLabel" data-target="#" href="http://example.com" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown trigger
<span class="caret"></span>
</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
...
</ul>
</div>
Call the dropdowns via JavaScript:
$(‘.dropdown-toggle‘).dropdown()
data-toggle="dropdown" still requiredRegardless of whether you call your dropdown via JavaScript or instead use the data-api, data-toggle="dropdown"is always required to be present on the dropdown‘s trigger element.
None
Toggles the dropdown menu of a given navbar or tabbed navigation.
All dropdown events are fired at the .dropdown-menu‘s parent element.
| Event Type | Description |
|---|---|
| show.bs.dropdown | This event fires immediately when the show instance method is called. The toggling anchor element is available as the relatedTarget property of the event. |
| shown.bs.dropdown | This event is fired when the dropdown has been made visible to the user (will wait for CSS transitions, to complete). The toggling anchor element is available as the relatedTarget property of the event. |
| hide.bs.dropdown | This event is fired immediately when the hide instance method has been called. The toggling anchor element is available as the relatedTarget property of the event. |
| hidden.bs.dropdown | This event is fired when the dropdown has finished being hidden from the user (will wait for CSS transitions, to complete). The toggling anchor element is available as the relatedTarget property of the event. |
$(‘#myDropdown‘).on(‘show.bs.dropdown‘, function () {
// do something…
})
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.

Scrollspy currently requires the use of a Bootstrap nav component for proper highlighting of active links.
No matter the implementation method, scrollspy requires the use of position: relative; on the element you‘re spying on. In most cases this is the <body>.
To easily add scrollspy behavior to your topbar navigation, add data-spy="scroll" to the element you want to spy on (most typically this would be the <body>). Then add the data-target attribute with the ID or class of the parent element of any Bootstrap .nav component.
body {
position: relative;
}
<body data-spy="scroll" data-target=".navbar-example">
...
<div class="navbar-example">
<ul class="nav nav-tabs" role="tablist">
...
</ul>
</div>
...
</body>
After adding position: relative; in your CSS, call the scrollspy via JavaScript:
$(‘body‘).scrollspy({ target: ‘.navbar-example‘ })
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>.
:visible target elements ignoredTarget elements that are not :visible according to jQuery will be ignored and their corresponding nav items will never be highlighted.
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 can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as indata-offset="".
| Name | type | default | description |
|---|---|---|---|
| offset | number | 10 | Pixels to offset from top when calculating position of scroll. |
| Event Type | Description |
|---|---|
| activate.bs.scrollspy | This event fires whenever a new item becomes activated by the scrollspy. |
$(‘#myScrollspy‘).on(‘activate.bs.scrollspy‘, function () {
// do something…
})
Add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus.

This plugin extends the tabbed navigation component to add tabbable areas.
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)
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, while adding the nav and nav-pills classes will apply pill styling.
<!-- Nav tabs -->
<ul class="nav nav-tabs" role="tablist">
<li role="presentation" class="active"><a href="#home" role="tab" data-toggle="tab">Home</a></li>
<li role="presentation"><a href="#profile" role="tab" data-toggle="tab">Profile</a></li>
<li role="presentation"><a href="#messages" role="tab" data-toggle="tab">Messages</a></li>
<li role="presentation"><a href="#settings" role="tab" data-toggle="tab">Settings</a></li>
</ul>
<!-- Tab panes -->
<div class="tab-content">
<div role="tabpanel" class="tab-pane active" id="home">...</div>
<div role="tabpanel" class="tab-pane" id="profile">...</div>
<div role="tabpanel" class="tab-pane" id="messages">...</div>
<div role="tabpanel" class="tab-pane" id="settings">...</div>
</div>
To make tabs fade in, add .fade to each .tab-pane. The first tab pane must also have .in to properly fade in initial content.
<div class="tab-content">
<div role="tabpanel" class="tab-pane fade in active" id="home">...</div>
<div role="tabpanel" class="tab-pane fade" id="profile">...</div>
<div role="tabpanel" class="tab-pane fade" id="messages">...</div>
<div role="tabpanel" class="tab-pane fade" id="settings">...</div>
</div>
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" role="tablist" id="myTab">
<li role="presentation" class="active"><a href="#home" role="tab" data-toggle="tab">Home</a></li>
<li role="presentation"><a href="#profile" role="tab" data-toggle="tab">Profile</a></li>
<li role="presentation"><a href="#messages" role="tab" data-toggle="tab">Messages</a></li>
<li role="presentation"><a href="#settings" role="tab" data-toggle="tab">Settings</a></li>
</ul>
<div class="tab-content">
<div role="tabpanel" class="tab-pane active" id="home">...</div>
<div role="tabpanel" class="tab-pane" id="profile">...</div>
<div role="tabpanel" class="tab-pane" id="messages">...</div>
<div role="tabpanel" class="tab-pane" id="settings">...</div>
</div>
<script>
$(function () {
$(‘#myTab a:last‘).tab(‘show‘)
})
</script>
When showing a new tab, the events fire in the following order:
hide.bs.tab (on the current active tab)show.bs.tab (on the to-be-shown tab)hidden.bs.tab (on the previous active tab, the same one as for the hide.bs.tab event)shown.bs.tab (on the newly-active just-shown tab, the same one as for the show.bs.tab event)If no tab was already active, then the hide.bs.tab and hidden.bs.tab events will not be fired.
| Event Type | Description |
|---|---|
| show.bs.tab | This event fires on tab show, but before the new tab has been shown. Use event.target andevent.relatedTarget to target the active tab and the previous active tab (if available) respectively. |
| shown.bs.tab | 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. |
| hide.bs.tab | This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Useevent.target and event.relatedTarget to target the current active tab and the new soon-to-be-active tab, respectively. |
| hidden.bs.tab | This event fires after a new tab is shown (and thus the previous active tab is hidden). Use event.targetand event.relatedTarget to target the previous active tab and the new active tab, respectively. |
$(‘a[data-toggle="tab"]‘).on(‘shown.bs.tab‘, function (e) {
e.target // newly activated tab
e.relatedTarget // previous active tab
})
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.
Tooltips with zero-length titles are never displayed.

Four options are available: top, right, bottom, and left aligned.
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="left" title="Tooltip on left">Tooltip on left</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="top" title="Tooltip on top">Tooltip on top</button>

<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="right" title="Tooltip on right">Tooltip on right</button>
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
When using tooltips on elements within a .btn-group or an .input-group, you‘ll have to specify the optioncontainer: ‘body‘ (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip is triggered).
Invoking $(...).tooltip(‘show‘) when the target element is display: none; will cause the tooltip to be incorrectly positioned.
To add a tooltip to a disabled or .disabled element, put the element inside of a <div> and apply the tooltip to that <div> instead.
The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.
Trigger the tooltip via JavaScript:
$(‘#example‘).tooltip(options)
The required markup for a tooltip is only a data attribute and title on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to top by the plugin).
Sometimes you want to add a tooltip to a hyperlink that wraps multiple lines. The default behavior of the tooltip plugin is to center it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.
<!-- HTML to write -->
<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>
<!-- Generated markup by the plugin -->
<div class="tooltip top" role="tooltip">
<div class="tooltip-arrow"></div>
<div class="tooltip-inner">
Some tooltip text!
</div>
</div>
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as indata-animation="".
| Name | Type | Default | Description |
|---|---|---|---|
| animation | boolean | true | Apply a CSS fade transition to the tooltip |
| container | string | false | false |
Appends the tooltip to a specific element. Example: |

| 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 | auto. When a function is used to determine the placement, it is called with the tooltip DOM node as its first argument and the triggering element DOM node as its second. The |

| shown.bs.tooltip | This event is fired when the tooltip has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.tooltip | This event is fired immediately when the hide instance method has been called. |

Add small overlays of content, like those on the iPad, to any element for housing secondary information.
Popovers whose both title and content are zero-length are never displayed.
Popovers require the tooltip plugin to be included in your version of Bootstrap.
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
When using popovers on elements within a .btn-group or an .input-group, you‘ll have to specify the optioncontainer: ‘body‘ (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).
Invoking $(...).popover(‘show‘) when the target element is display: none; will cause the popover to be incorrectly positioned.
To add a popover to a disabled or .disabled element, put the element inside of a <div> and apply the popover to that <div> instead.
Sometimes you want to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to center it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.
Four options are available: top, right, bottom, and left aligned.

Use the focus trigger to dismiss popovers on the next click that the user makes.
For proper cross-browser and cross-platform behavior, you must use the <a> tag, not the <button> tag, and you also must include a tabindex attribute.
<a href="#" tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" data-trigger="focus" title="Dismissible popover" data-content="And here‘s some amazing content. It‘s very engaging. Right?">Dismissible popover</a>
Enable popovers via JavaScript:
$(‘#example‘).popover(options)
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as indata-animation="".

Initializes popovers for an element collection.
Reveals an element‘s popover. Popovers whose both title and content are zero-length are never displayed.
$(‘#element‘).popover(‘show‘)
Hides an element‘s popover.
$(‘#element‘).popover(‘hide‘)
Toggles an element‘s popover.
$(‘#element‘).popover(‘toggle‘)
Hides and destroys an element‘s popover.
$(‘#element‘).popover(‘destroy‘)
| Event Type | Description |
|---|---|
| show.bs.popover | This event fires immediately when the show instance method is called. |
| shown.bs.popover | This event is fired when the popover has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.popover | This event is fired immediately when the hide instance method has been called. |
| hidden.bs.popover | This event is fired when the popover has finished being hidden from the user (will wait for CSS transitions to complete). |
$(‘#myPopover‘).on(‘hidden.bs.popover‘, function () {
// do something…
})
Add dismiss functionality to all alert messages with this plugin.
When using a .close button, it must be the first child of the .alert-dismissible and no text content may come before it in the markup.
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.
Just add data-dismiss="alert" to your close button to automatically give an alert close functionality. Closing an alert removes it from the DOM.
<button type="button" class="close" data-dismiss="alert"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<button type="button" class="close" data-dismiss="alert">
<span aria-hidden="true">×</span>
<span class="sr-only">Close</span>
</button>
To have your alerts use animation when closing, make sure they have the .fade and .in classes already applied to them.
Makes an alert listen for click events on descendant elements which have the data-dismiss="alert" attribute. (Not necessary when using the data-api‘s auto-initialization.)
Closes an alert by removing it from the DOM. If the .fade and .in classes are present on the element, the alert will fade out before it is removed.
Bootstrap‘s alert plugin exposes a few events for hooking into alert functionality.
| Event Type | Description |
|---|---|
| close.bs.alert | This event fires immediately when the close instance method is called. |
| closed.bs.alert | This event is fired when the alert has been closed (will wait for CSS transitions to complete). |
$(‘#myAlert‘).on(‘closed.bs.alert‘, function () {
// do something…
})
Do more with buttons. Control button states or create groups of buttons for more components like toolbars.
Firefox persists form control states (disabledness and checkedness) across page loads. A workaround for this is to use autocomplete="off". See Mozilla bug #654072.
Add data-loading-text="Loading..." to use a loading state on a button.
For the sake of this demonstration, we are using data-loading-text and $().button(‘loading‘), but that‘s not the only state you can use. See more on this below in the $().button(string) documentation.
<button type="button" id="myButton" data-loading-text="Loading..." class="btn btn-primary" autocomplete="off">
Loading state
</button>
<script>
$(‘#myButton‘).on(‘click‘, function () {
var $btn = $(this).button(‘loading‘)
// business logic...
$btn.button(‘reset‘)
})
</script>
Add data-toggle="button" to activate toggling on a single button.
<button type="button" class="btn btn-primary" data-toggle="button" aria-pressed="false" autocomplete="off">
Single toggle
</button>
.active and aria-pressed="true"For pre-toggled buttons, you must add the .active class and the aria-pressed="true" attribute to the buttonyourself.
Add data-toggle="buttons" to a .btn-group containing checkbox or radio inputs to enable toggling in their respective styles.
.activeFor preselected options, you must add the .active class to the input‘s label yourself.
If the checked state of a checkbox button is updated without firing a click event on the button (e.g. via <input type="reset"> or via setting the checked property of the input), you will need to toggle the .active class on the input‘s label yourself.
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary active">
<input type="checkbox" autocomplete="off" checked> Checkbox 1 (pre-checked)
</label>
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off"> Checkbox 2
</label>
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off"> Checkbox 3
</label>
</div>
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary active">
<input type="radio" name="options" id="option1" autocomplete="off" checked> Radio 1 (preselected)
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option2" autocomplete="off"> Radio 2
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option3" autocomplete="off"> Radio 3
</label>
</div>
Toggles push state. Gives the button the appearance that it has been activated.
Resets button state - swaps text to original text.
Swaps text to any data defined text state.
<button type="button" id="myStateButton" data-complete-text="finished!" class="btn btn-primary" autocomplete="off">
...
</button>
<script>
$(‘#myStateButton‘).on(‘click‘, function () {
$(this).button(‘complete‘) // button text will be "finished!"
})
</script>
Get base styles and flexible support for collapsible components like accordions and navigation.
Collapse requires the transitions plugin to be included in your version of Bootstrap.
Using the collapse plugin, we built a simple accordion by extending the panel component.
<div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true">
<div class="panel panel-default">
<div class="panel-heading" role="tab" id="headingOne">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">

It‘s also possible to swap out .panel-bodys with .list-groups.
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" aria-expanded="true" aria-controls="demo">
simple collapsible
</button>
<div id="demo" class="collapse in">...</div>
Be sure to add aria-expanded to the control element. This attribute explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If the collapsible element is closed by default, it should have a value of aria-expanded="false". If you‘ve set the collapsible element to be open by default using the in class, set aria-expanded="true" on the control instead. The plugin will automatically toggle this attribute based on whether or not the collapsible element has been opened or closed.
Additionally, if your control element is targetting a single collapsible element – i.e. the data-target attribute is pointing to an id selector – you may add an additional aria-controls attribute to the control element, containing the id of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.
The collapse plugin utilizes a few classes to handle the heavy lifting:
.collapse hides the content.collapse.in shows the content.collapsing is added when the transition starts, and removed when it finishesThese classes can be found in component-animations.less.
Just add data-toggle="collapse" and a data-target to the 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 collapseto 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.
Enable manually with:
$(‘.collapse‘).collapse()
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as indata-parent="".
| Name | type | default | description |
|---|---|---|---|
| parent | selector | false | If a selector is provided, then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this is dependent on the panel class) |
| toggle | boolean | true | Toggles the collapsible element on invocation |
Activates your content as a collapsible element. Accepts an optional options object.
$(‘#myCollapsible‘).collapse({
toggle: false
})
Toggles a collapsible element to shown or hidden.
Shows a collapsible element.
Hides a collapsible element.
Bootstrap‘s collapse class exposes a few events for hooking into collapse functionality.
| Event Type | Description |
|---|---|
| show.bs.collapse | This event fires immediately when the show instance method is called. |
| shown.bs.collapse | This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.collapse | This event is fired immediately when the hide method has been called. |
| hidden.bs.collapse | This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete). |
$(‘#myCollapsible‘).on(‘hidden.bs.collapse‘, function () {
// do something…
})
A slideshow component for cycling through elemnts, like a carousel. Nested carousels are not supported.
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
<li data-target="#carousel-example-generic" data-slide-to="1"></li>
<li data-target="#carousel-example-generic" data-slide-to="2"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div class="item active">
<img src="..." alt="...">
<div class="carousel-caption">
...
</div>
</div>
<div class="item">
<img src="..." alt="...">
<div class="carousel-caption">
...
</div>
</div>
...
</div>
<!-- Controls -->
<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
<span class="sr-only">Next</span>
</a>
</div>
Bootstrap exclusively uses CSS3 for its animations, but Internet Explorer 8 & 9 don‘t support the necessary CSS properties. Thus, there are no slide transition animations when using these browsers. We have intentionally decided not to include jQuery-based fallbacks for the transitions.
Add captions to your slides easily with the .carousel-caption element within any .item. Place just about any optional HTML within there and it will be automatically aligned and formatted.
<div class="item">
<img src="..." alt="...">
<div class="carousel-caption">
<h3>...</h3>
<p>...</p>
</div>
</div>
The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.
Carousels require the use of an id on the outermost container (the .carousel) for carousel controls to function properly. When adding multiple carousels, or when changing a carousel‘s id, be sure to update the relevant controls.
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 its current position. Alternatively, use data-slide-to to pass a raw slide index to the carousel data-slide-to="2", which shifts the slide position to a particular index beginning with 0.
The data-ride="carousel" attribute is used to mark a carousel as animating starting at page load. It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.
Call carousel manually with:
$(‘.carousel‘).carousel()
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as indata-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. |
| wrap | boolean | true | Whether the carousel should cycle continuously or have hard stops. |
| keyboard | boolean | true | Whether the carousel should react to keyboard events. |
Initializes the carousel with an optional options object and starts cycling through items.
$(‘.carousel‘).carousel({
interval: 2000
})
Cycles through the carousel items from left to right.
Stops the carousel from cycling through items.
Cycles the carousel to a particular frame (0 based, similar to an array).
Cycles to the previous item.
Cycles to the next item.
Bootstrap‘s carousel class exposes two events for hooking into carousel functionality.
Both events have the following additional properties:
direction: The direction in which the carousel is sliding (either "left" or "right").relatedTarget: The DOM element that is being slid into place as the active item.| Event Type | Description |
|---|---|
| slide.bs.carousel | This event fires immediately when the slide instance method is invoked. |
| slid.bs.carousel | This event is fired when the carousel has completed its slide transition. |
$(‘#myCarousel‘).on(‘slide.bs.carousel‘, function () {
// do something…
})
The subnavigation on the right is a live demo of the affix plugin.
Use the affix plugin via data attributes or manually with your own JavaScript. In both situations, you must provide CSS for the positioning and width of your affixed content.
The affix plugin toggles between three classes, each representing a particular state: .affix, .affix-top, and .affix-bottom. You must provide the styles for these classes yourself (independent of this plugin) to handle the actual positions.
Here‘s how the affix plugin works:
.affix-top to indicate the element is in its top-most position. At this point no CSS positioning is required..affix replaces .affix-top and sets position: fixed; (provided by Bootstrap‘s CSS)..affix with .affix-bottom. Since offsets are optional, setting one requires you to set the appropriate CSS. In this case, add position: absolute; when necessary. The plugin uses the data attribute or JavaScript option to determine where to position the element from there.Follow the above steps to set your CSS for either of the usage options below.
To easily add affix behavior to any element, just add data-spy="affix" to the element you want to spy on. Use offsets to define when to toggle the pinning of an element.
<div data-spy="affix" data-offset-top="60" data-offset-bottom="200">
...
</div>
Call the affix plugin via JavaScript:
$(‘#myAffix‘).affix({
offset: {
top: 100,
bottom: function () {
return (this.bottom = $(‘.footer‘).outerHeight(true))
}
}
})
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as indata-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 bottom directions. To provide a unique, bottom and top offset just provide an object offset: { top: 10 } or offset: { top: 10, bottom: 5 }. Use a function when you need to dynamically calculate an offset. |
| target | selector | node | jQuery element | thewindowobject |
Specifies the target element of the affix. |
Bootstrap‘s affix plugin exposes a few events for hooking into affix functionality.
| Event Type | Description |
|---|---|
| affix.bs.affix | This event fires immediately before the element has been affixed. |
| affixed.bs.affix | This event is fired after the element has been affixed. |
| affix-top.bs.affix | This event fires immediately before the element has been affixed-top. |
| affixed-top.bs.affix | This event is fired after the element has been affixed-top. |
| affix-bottom.bs.affix | This event fires immediately before the element has been affixed-bottom. |
| affixed-bottom.bs.affix | This event is fired after the element has been affixed-bottom. |
