Last Updated : 24 Aug, 2021

jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful and optimized framework, platform-independent, and widely supported. The jqxComboBox is used to represent a jQuery Combobox widget that contains an input field with autocomplete functionality and a list of selectable items displayed in a drop-down.

The change event is used to trigger when the user selects an item.

Syntax:

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