Include only one.</p> </div> <div class="bs-callout bs-callout-danger" id=callout-overview-dependencies> <h4>Plugin dependencies</h4> <p>Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included <strong>before</strong> the plugin files). <a href=https://github.com/twbs/bootstrap/blob/v3.3.7/bower.json>Consult our <code>bower.json</code></a> to see which versions of jQuery are supported.</p> </div> <h2 id=js-data-attrs>Data attributes</h2> <p>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.</p> <p>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 document namespaced with <code>data-api</code>. This looks like this:</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=nx>$</span><span class=p>(</span><span class=nb>document</span><span class=p>).</span><span class=nx>off</span><span class=p>(</span><span class=s1>'.data-api'</span><span class=p>)</span></code></pre></figure> <p>Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=nx>$</span><span class=p>(</span><span class=nb>document</span><span class=p>).</span><span class=nx>off</span><span class=p>(</span><span class=s1>'.alert.data-api'</span><span class=p>)</span></code></pre></figure> <div class="bs-callout bs-callout-danger" id=callout-overview-single-data> <h4>Only one plugin per element via data attributes</h4> <p>Don't use data attributes from multiple plugins on the same element. For example, a button cannot both have a tooltip and toggle a modal. To accomplish this, use a wrapping element.</p> </div> <h2 id=js-programmatic-api>Programmatic API</h2> <p>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.</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=nx>$</span><span class=p>(</span><span class=s1>'.btn.danger'</span><span class=p>).</span><span class=nx>button</span><span class=p>(</span><span class=s1>'toggle'</span><span class=p>).</span><span class=nx>addClass</span><span class=p>(</span><span class=s1>'fat'</span><span class=p>)</span></code></pre></figure> <p>All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=nx>$</span><span class=p>(</span><span class=s1>'#myModal'</span><span class=p>).</span><span class=nx>modal</span><span class=p>()</span> <span class=c1>// initialized with defaults</span>
<span class=nx>$</span><span class=p>(</span><span class=s1>'#myModal'</span><span class=p>).</span><span class=nx>modal</span><span class=p>({</span> <span class=na>keyboard</span><span class=p>:</span> <span class=kc>false</span> <span class=p>})</span> <span class=c1>// initialized with no keyboard</span>
<span class=nx>$</span><span class=p>(</span><span class=s1>'#myModal'</span><span class=p>).</span><span class=nx>modal</span><span class=p>(</span><span class=s1>'show'</span><span class=p>)</span> <span class=c1>// initializes and invokes show immediately</span></code></pre></figure> <p>Each plugin also exposes its raw constructor on a <code>Constructor</code> property: <code>$.fn.popover.Constructor</code>. If you'd like to get a particular plugin instance, retrieve it directly from an element: <code>$('[rel="popover"]').data('popover')</code>.</p> <h4>Default settings</h4> <p>You can change the default settings for a plugin by modifying the plugin's <code>Constructor.DEFAULTS</code> object:</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=nx>$</span><span class=p>.</span><span class=nx>fn</span><span class=p>.</span><span class=nx>modal</span><span class=p>.</span><span class=nx>Constructor</span><span class=p>.</span><span class=nx>DEFAULTS</span><span class=p>.</span><span class=nx>keyboard</span> <span class=o>=</span> <span class=kc>false</span> <span class=c1>// changes default for the modal plugin's `keyboard` option to false</span></code></pre></figure> <h2 id=js-noconflict>No conflict</h2> <p>Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call <code>.noConflict</code> on the plugin you wish to revert the value of.</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=kd>var</span> <span class=nx>bootstrapButton</span> <span class=o>=</span> <span class=nx>$</span><span class=p>.</span><span class=nx>fn</span><span class=p>.</span><span class=nx>button</span><span class=p>.</span><span class=nx>noConflict</span><span class=p>()</span> <span class=c1>// return $.fn.button to previously assigned value</span>
<span class=nx>$</span><span class=p>.</span><span class=nx>fn</span><span class=p>.</span><span class=nx>bootstrapBtn</span> <span class=o>=</span> <span class=nx>bootstrapButton</span> <span class=c1>// give $().bootstrapBtn the Bootstrap functionality</span></code></pre></figure> <h2 id=js-events>Events</h2> <p>Bootstrap provides custom events for most plugins' unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. <code>show</code>) is triggered at the start of an event, and its past participle form (ex. <code>shown</code>) is triggered on the completion of an action.</p> <p>As of 3.0.0, all Bootstrap events are namespaced.</p> <p>All infinitive events provide <code>preventDefault</code> functionality. This provides the ability to stop the execution of an action before it starts.</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=nx>$</span><span class=p>(</span><span class=s1>'#myModal'</span><span class=p>).</span><span class=nx>on</span><span class=p>(</span><span class=s1>'show.bs.modal'</span><span class=p>,</span> <span class=kd>function</span> <span class=p>(</span><span class=nx>e</span><span class=p>)</span> <span class=p>{</span>
<span class=k>if</span> <span class=p>(</span><span class=o>!</span><span class=nx>data</span><span class=p>)</span> <span class=k>return</span> <span class=nx>e</span><span class=p>.</span><span class=nx>preventDefault</span><span class=p>()</span> <span class=c1>// stops modal from being shown</span>
<span class=p>})</span></code></pre></figure> <h2 id=js-version-nums>Version numbers</h2> <p>The version of each of Bootstrap's jQuery plugins can be accessed via the <code>VERSION</code> property of the plugin's constructor. For example, for the tooltip plugin:</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=nx>$</span><span class=p>.</span><span class=nx>fn</span><span class=p>.</span><span class=nx>tooltip</span><span class=p>.</span><span class=nx>Constructor</span><span class=p>.</span><span class=nx>VERSION</span> <span class=c1>// => "3.3.7"</span></code></pre></figure> <h2 id=js-disabled>No special fallbacks when JavaScript is disabled</h2> <p>Bootstrap's plugins don't fall back particularly gracefully when JavaScript is disabled. If you care about the user experience in this case, use <a href=https://developer.mozilla.org/en-US/docs/Web/HTML/Element/noscript><code><noscript></code></a> to explain the situation (and how to re-enable JavaScript) to your users, and/or add your own custom fallbacks.</p> <div class="bs-callout bs-callout-warning" id=callout-third-party-libs> <h4>Third-party libraries</h4> <p><strong>Bootstrap does not officially support third-party JavaScript libraries</strong> like Prototype or jQuery UI. Despite <code>.noConflict</code> and namespaced events, there may be compatibility problems that you need to fix on your own.</p> </div> </div> <div class=bs-docs-section> <h1 class=page-header id=transitions>Transitions <small>transition.js</small></h1> <h2>About transitions</h2> <p>For simple transition effects, include <code>transition.js</code> once alongside the other JS files. If you're using the compiled (or minified) <code>bootstrap.js</code>, there is no need to include this—it's already there.</p> <h2>What's inside</h2> <p>Transition.js is a basic helper for <code>transitionEnd</code> events as well as a CSS transition emulator. It's used by the other plugins to check for CSS transition support and to catch hanging transitions.</p> <h2>Disabling transitions</h2> <p>Transitions can be globally disabled using the following JavaScript snippet, which must come after <code>transition.js</code> (or <code>bootstrap.js</code> or <code>bootstrap.min.js</code>, as the case may be) has loaded:</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=nx>$</span><span class=p>.</span><span class=nx>support</span><span class=p>.</span><span class=nx>transition</span> <span class=o>=</span> <span class=kc>false</span></code></pre></figure> </div> <div class=bs-docs-section> <h1 class=page-header id=modals>Modals <small>modal.js</small></h1> <p>Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.</p> <div class="bs-callout bs-callout-warning" id=callout-stacked-modals> <h4>Multiple open modals not supported</h4> <p>Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.</p> </div> <div class="bs-callout bs-callout-warning" id=callout-modal-markup-placement> <h4>Modal markup placement</h4> <p>Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality.</p> </div> <div class="bs-callout bs-callout-warning" id=callout-modal-mobile-caveats> <h4>Mobile device caveats</h4> <p>There are some caveats regarding using modals on mobile devices. <a href=../getting-started/#support-fixed-position-keyboards>See our browser support docs</a> for details.</p> </div> <p><strong class=text-danger>Due to how HTML5 defines its semantics, the <code>autofocus</code> HTML attribute has no effect in Bootstrap modals.</strong> To achieve the same effect, use some custom JavaScript:</p> <figure class=highlight><pre><code class=language-js data-lang=js><span class=nx>$</span><span class=p>(</span><span class=s1>'#myModal'</span><span class=p>).</span><span class=nx>on</span><span class=p>(</span><span class=s1>'shown.bs.modal'</span><span class=p>,</span> <span class=kd>function</span> <span class=p>()</span> <span class=p>{</span>

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 <code>aria-expanded="false"</code>. If you've set the collapsible element to be open by default using the <code>in</code> class, set <code>aria-expanded="true"</code> on the control instead. The plugin will automatically toggle this attribute based on whether or not the collapsible element has been opened or closed.</p> <p>Additionally, if your control element is targeting a single collapsible element – i.e. the <code>data-target</code> attribute is pointing to an <code>id</code> selector – you may add an additional <code>aria-controls</code> attribute to the control element, containing the <code>id</code> 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.</p> </div> <h2 id=collapse-usage>Usage</h2> <p>The collapse plugin utilizes a few classes to handle the heavy lifting:</p> <ul> <li><code>.collapse</code> hides the content</li> <li><code>.collapse.in</code> shows the content</li> <li><code>.collapsing</code> is added when the transition starts, and removed when it finishes</li> </ul> <p>These classes can be found in <code>component-animations.less</code>.</p> <h3>Via data attributes</h3> <p>Just add <code>data-toggle="collapse"</code> and a <code>data-target</code> to the element to automatically assign control of a collapsible element. The <code>data-target</code> attribute accepts a CSS selector to apply the collapse to. Be sure to add the class <code>collapse</code> to the collapsible element. If you'd like it to default open, add the additional class <code>in</code>.</p> <p>To add accordion-like group management to a collapsible control, add the data attribute <code>data-parent="#selector"</code>.

You must provide the styles, with the exception of <code>position: fixed;</code> on <code>.affix</code>, for these classes yourself (independent of this plugin) to handle the actual positions.</p> <p>Here's how the affix plugin works:</p> <ol> <li>To start, the plugin adds <code>.affix-top</code> to indicate the element is in its top-most position. At this point no CSS positioning is required.</li> <li>Scrolling past the element you want affixed should trigger the actual affixing. This is where <code>.affix</code> replaces <code>.affix-top</code> and sets <code>position: fixed;</code> (provided by Bootstrap's CSS).</li> <li>If a bottom offset is defined, scrolling past it should replace <code>.affix</code> with <code>.affix-bottom</code>. Since offsets are optional, setting one requires you to set the appropriate CSS. In this case, add <code>position: absolute;</code> when necessary. The plugin uses the data attribute or JavaScript option to determine where to position the element from there.</li> </ol> <p>Follow the above steps to set your CSS for either of the usage options below.</p> <h3>Via data attributes</h3> <p>To easily add affix behavior to any element, just add <code>data-spy="affix"</code> to the element you want to spy on.
