Input type="range" polyfill (slider control)

Questions or comments?

Purpose

The <input type="range" /> element enables the display of a slider control bar. Because some browsers do not support this functionality natively, this polyfill emulates the same functionality using generic HTML and WAI-ARIA.

Working example

How to implement

To use the polyfill, a standard input type="range" element must be used. In cases where a browser doesn't support the input type="range" element, the polyfill is automatically loaded.

Configuration options

Events

Event Trigger What it does
wb-init.wb-slider Triggered manually (e.g., $( "input[type='range']" ).trigger( "wb-init.wb-slider" );). Used to manually initialize the input type="range" polyfill. Note: The progress polyfill will be initialized automatically unless the input type="range" element is added after the page has already loaded.
wb-update.wb-slider Triggered manually (e.g., $( "input[type='range']" ).trigger( "wb-update.wb-slider" );). Used to manually update the input type="range" polyfill.
wb-ready.wb-slider (v4.0.5+) Triggered automatically after the progress polyfill initializes. Note: This event will only be triggered if the polyfill is loaded. The polyfill will not load for browsers with native input type="range" support. Used to identify where the input type="range" polyfill initialized (target of the event) 
$( document ).on( "wb-ready.wb-slider", "input[type='range']", function( event ) {
});
$( "input[type='range']" ).on( "wb-ready.wb-slider", function( event ) {
});
wb-updated.wb-slider (v4.0.5+) Triggered automatically after the input type="range" polyfill is updated. Note: This event will only be triggered if the polyfill is loaded. The polyfill will not load for browsers with native input type="range" support. Used to identify where the input type="range" polyfill initialized (target of the event) 
$( document ).on( "wb-updated.wb-slider", "input[type='range']", function( event ) {
});
$( "input[type='range']" ).on( "wb-updated.wb-slider", function( event ) {
});
wb-ready.wb (v4.0.5+) Triggered automatically when WET has finished loading and executing. Used to identify when all WET plugins and polyfills have finished loading and executing. 
$( document ).on( "wb-ready.wb", function( event ) {
});
