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 checkAll() method is used to check all the items of the stated list when the checkboxes property value is set to true. This method has no parameters and does not return anything.

Syntax:

$("#jqxListBox").jqxListBox('checkAll');
