|

|
|
<h2 id="individual-or-compiled">Individual or compiled</h2>
|
|
<p>Plugins can be included individually (using Bootstrap’s individual <code>js/dist/*.js</code>), or all at once using <code>bootstrap.js</code> or the minified <code>bootstrap.min.js</code> (don’t include both).</p>
|
|
<p>If you use a bundler (Webpack, Rollup…), you can use <code>/js/dist/*.js</code> files which are UMD ready.</p>
|
|
<h2 id="dependencies">Dependencies</h2>
|
|
<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 <strong>all plugins depend on jQuery</strong> (this means jQuery must be included <strong>before</strong> the plugin files). <a href="https://github.com/twbs/bootstrap/blob/v4.6.0/package.json">Consult our <code>package.json</code></a> to see which versions of jQuery are supported.</p>
|
|
<p>Our dropdowns, popovers and tooltips also depend on <a href="https://popper.js.org/">Popper.js</a>.</p>
|
|
<h2 id="data-attributes">Data attributes</h2>
|
|
<p>Nearly all Bootstrap plugins can be enabled and configured through HTML alone with data attributes (our preferred way of using JavaScript functionality). Be sure to <strong>only use one set of data attributes on a single element</strong> (e.g., you cannot trigger a tooltip and modal from the same button.)</p>
|
|
<p>However, in some situations it may be desirable to disable this functionality. To disable the data attribute API, unbind all events on the document namespaced with <code>data-api</code> like so:</p>
|
|
<div class="highlight"><pre class="chroma"><code class="language-js" data-lang="js"><span class="nx">$</span><span class="p">(</span><span class="nb">document</span><span class="p">).</span><span class="nx">off</span><span class="p">(</span><span class="s1">'.data-api'</span><span class="p">)</span>
|
|
</code></pre></div><p>Alternatively, to target a specific plugin, just include the plugin’s name as a namespace along with the data-api namespace like this:</p>
|
|
<div class="highlight"><pre class="chroma"><code class="language-js" data-lang="js"><span class="nx">$</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></div><div class="bd-callout bd-callout-warning">
|
|
<h2 id="selectors">Selectors</h2>
|
|
<p>Currently to query DOM elements we use the native methods <code>querySelector</code> and <code>querySelectorAll</code> for performance reasons, so you have to use <a href="https://www.w3.org/TR/CSS21/syndata.html#value-def-identifier">valid selectors</a>.
|
|
If you use special selectors, for example: <code>collapse:Example</code> be sure to escape them.
|
|
</div>
|
|
|
|
<h2 id="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>All infinitive events provide <a href="https://developer.mozilla.org/en-US/docs/Web/API/Event/preventDefault"><code>preventDefault()</code></a> functionality. This provides the ability to stop the execution of an action before it starts. Returning false from an event handler will also automatically call <code>preventDefault()</code>.</p>
|
|
<div class="highlight"><pre class="chroma"><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">event</span><span class="p">)</span> <span class="p">{</span>

|
|
<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>

|
<h3 id="asynchronous-functions-and-transitions">Asynchronous functions and transitions</h3>
|
|
<p>All programmatic API methods are <strong>asynchronous</strong> and return to the caller once the transition is started but <strong>before it ends</strong>.</p>
|
|
<p>In order to execute an action once the transition is complete, you can listen to the corresponding event.</p>

</span></code></pre></div><h3 id="default-settings">Default settings</h3>
|
|
<p>You can change the default settings for a plugin by modifying the plugin’s <code>Constructor.Default</code> object:</p>
|
|
<div class="highlight"><pre class="chroma"><code class="language-js" data-lang="js"><span class="c1">// changes default for the modal plugin's `keyboard` option to false

|
|
</code></pre></div><h2 id="no-conflict">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>
|
|
<div class="highlight"><pre class="chroma"><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></code></pre></div><h2 id="version-numbers">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>
|
|
<div class="highlight"><pre class="chroma"><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">// => "4.6.0"
|
|
</span></code></pre></div><h2 id="no-special-fallbacks-when-javascript-is-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="bd-callout bd-callout-warning">
|
|
<h5 id="third-party-libraries">Third-party libraries</h5>
|
|
<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.
|
|
</div>
|
|
|
|
<h2 id="util">Util</h2>
|
|
<p>All Bootstrap’s JavaScript files depend on <code>util.js</code> and it has to be included alongside the other JavaScript 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>
|
|
<p><code>util.js</code> includes utility functions and 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 id="sanitizer">Sanitizer</h2>
|
|
<p>Tooltips and Popovers use our built-in sanitizer to sanitize options which accept HTML.</p>
