jQWidgets jqxBulletChart Change Event

  • Last Updated : 19 Jul, 2021
Geek Week

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 jqxBulletChart represents a jQuery bullet chart widget that features two measures, a primary one and a comparative one, and displays them in the context of a number of differently styled qualitative ranges.

The change event is triggered when the value is changed.

Syntax:

$('selector').on('change', function () {
});

Linked Files: Download jQWidgets from the link. In the HTML file, locate the script files in the downloaded folder.
