jQWidgets jqxCheckBox indeterminate Event

Last Updated : 23 May, 2022

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 jqxCheckBox widget is used to display a check box that allows users to select or deselect the checkbox.

The jqxCheckBox indeterminate event is triggered when the checkbox’s checked property is going to be null. To apply this event, first, we need to add hasThreeStates property to true.

Syntax:

$('#jqxCheckBox').on('indeterminate', function (event) { 
    // Code
});

Linked Files: Download jQWidgets zipped files from the official website link and unzip them in a folder. Then create an HTML file, and locate the script files in the downloaded folder.

<link rel=”stylesheet” href=”jqwidgets/styles/jqx.base.css” type=”text/css” />
<script type=”text/javascript” src=”scripts/jquery-1.11.1.min.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxcore.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxcheckbox.js”></script>
