<p>To add a slider widget to your page, use a standard <code>input</code> with the <code>type="range"</code> attribute. The input's <code>value</code> is used to configure the starting position of the handle and the value is populated in the text input. Specify <code>min</code> and <code>max</code> attribute values to set the slider's range. If you want to constrain input to specific increments, add the <code>step</code> attribute. Set the <code>value</code> attribute to define the initial value. The framework will parse these attributes to configure the slider widget. View the <a href="../../api/data-attributes.html">data- attribute reference</a> to see all the possible attributes you can add to sliders.</p>
|
|
|
|
<p>As you drag the slider's handle, the framework will update the native input's value (and vice-versa) so they are always in sync; this ensures that the value is submitted with the form.</p>
|
|
<p>Set the <code>for</code> attribute of the <code>label</code> to match the ID of the <code>input</code> so they are semantically associated. It's possible to <a href="../docs-forms.html">accessibly hide the label</a> if it's not desired in the page layout, but we require that it is present in the markup for semantic and accessibility reasons.</p>
|
|
|
|
<p>The framework will find all <code>input</code> elements with a <code>type="range"</code> and automatically enhance them into a slider with an accompanying input, no need to apply a <code>data-role</code> attribute. To prevent the automatic enhancement of this input into a slider, add <code>data-role="none"</code> attribute to the <code>input</code> and wrap them in a <code>div</code> with the <code> data-role="fieldcontain"</code> attribute to group them. In this example, the acceptable range is 0-100 and the step increment is 5. </p>
|
|
|
|
<pre><code>
|
|
<label for="slider-0">Input slider:</label>
|
|
<input type="range" name="slider" id="slider-0" value="25" min="0" max="100" step="5" />
|
|
</code></pre>
|
|
|
|
<p>The default slider with these settings is displayed like this:</p>
|
|
<label for="slider-0">Input slider:</label>
|
|
<input type="range" name="slider-1" id="slider-0" value="25" min="0" max="100" step="5" />
|
|
|
|
<p>Optionally wrap the slider markup in a container with the <code>data-role="fieldcontain"</code> attribute to help visually group it in a longer form. In this example, the <code>step</code> attribute is omitted to allow any whole number value to be selected.</p>
|
|
|
|
|
|
<pre><code>
|
|
<strong><div data-role="fieldcontain">
|
|
</strong> <label for="slider">Input slider:</label>
|
|
<input type="range" name="slider" id="slider" value="25" min="0" max="100" />
|
|
<strong></div>
|
|
</strong></code></pre>
|
|
|
|
<p>The slider is now displayed like this:</p>
|
|
<div data-role="fieldcontain">
|
|
<label for="slider-1">Input slider:</label>
|
|
<input type="range" name="slider-1" id="slider-1" value="25" min="0" max="100" />
|
|
</div>
|
|
|
|
<p>Sliders also respond to key commands. Right Arrow, Up Arrow and Page Up keys increase the value; Left Arrow, Down Arrow and Page Down keys decrease it. To move the slider to its minimum or maximum value, use the Home or End key, respectively.</p>
|
|
|
|
|
|
<h2>Calling the slider plugin</h2>
|
|
|
|
<p>This plugin will auto initialize on any page that contains a text <code>input</code> with the <code>type="range"</code> attribute. However, if needed you can directly call the <code>slider</code> plugin on any selector, just like any jQuery plugin:</p>
|
|
<pre><code>
|
|
$('input').slider();
|
|
</code></pre>
|
|
|
|
|
|
<h2>Theming the slider</h2>
|
|
<p>To set the theme swatch for the slider, add a <code>data-theme</code> attribute to the <code>input</code> which will apply the theme to both the input, handle and track. The track swatch can be set separately by adding the <code>data-track-theme</code> attribute to apply the down state version of the selected button swatch.</p>
|
|
|
|
<pre><code>
|
|
<div data-role="fieldcontain">
|
|
<label for="slider-2">Input slider:</label>
|
|
<input type="range" name="slider-2" id="slider-2" value="25" min="0" max="100" <strong>data-theme="a" data-track-theme="b"</strong> />
|
|
</div>
|
|
</code></pre>
|
|
|
|
<p>This will produce a themed slider:</p>
|
|
<div data-role="fieldcontain">
|
|
<label for="slider-2">Input slider:</label>
|
|
<input type="range" name="slider-2" id="slider-2" value="25" min="0" max="100" data-theme="a" data-track-theme="b" />
|
|
</div>
|
|
</form>
|
|
</div><!--/content-primary -->

<div class="content-secondary">
|
|
|
|
<div data-role="collapsible" data-collapsed="true" data-theme="b" data-content-theme="d">
