Introduction: 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 selectIndex() method is used to select an item from the stated list. The index here is zero-based, in other words, in order to select the initial item of the list, the ‘selectIndex‘ method must be invoked along with parameter zero. It does not return anything.

Syntax:

$("#jqxListBox").jqxListBox('selectIndex', Index);

Parameter:

  • Index: The stated index. It is of type number.
