Methods

Events

The jQuery UI Slider plugin makes selected elements into sliders. There are various options such as multiple handles and ranges. The handle can be moved with the mouse or the arrow keys.

The slider widget will create handle elements with the class ui-slider-handle on initialization. You can specify custom handle elements by creating and appending the elements and adding the ui-slider-handle class before initialization. It will only create the number of handles needed to match the length of value/values. For example, if you specify values: [ 1, 5, 18 ] and create one custom handle, the plugin will create the other two.

Theming

The slider widget uses the jQuery UI CSS framework to style its look and feel. If slider specific styling is needed, the following CSS class names can be used for overrides or as keys for the classes option:

  • ui-slider: The track of the slider control. This element will additionally have a class name of ui-slider-horizontal or ui-slider-vertical depending on the orientation option of the slider.
    • ui-slider-handle: One of the slider handles.
    • ui-slider-range: The selected range used when the range option is set. This element can additionally have a class of ui-slider-range-min or ui-slider-range-max if the range option is set to "min" or "max" respectively.

Dependencies

Additional Notes:

  • This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.
