jQWidgets jqxScrollBar valueChanged Event

  • Last Updated : 24 Nov, 2021

jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxScrollBar is used for representing a jQuery widget that provides a scroll bar that has a sliding thumb whose position corresponds to a value.

The valueChanged event is triggered when the value of the specified jqxScrollBar is changed.

Syntax:

$('#jqxScrollBar').on('valueChanged', function (event)  
{
   var currentValue = event.currentValue;  
   var previousValue = event.previousValue;
});
