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 jqxListBox is used to illustrate a jQuery ListBox widget which comprises a list of electable elements.

The selectedIndex property is used to set or return the index that is selected. It is of type number and its default value is -1.

Syntax:

To set the selectedIndex property:

$("#jqxListBox").jqxListBox({selectedIndex: 2 }); 

 

To get the selectedIndex property:

var selectedIndex = $('#jqxListBox').jqxListBox('selectedIndex');
