Last Updated : 26 Oct, 2021

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 jqxRadioButton widget represents a jQuery radio button that is used to make a choice among a set of mutually exclusive and related options. This widget is used to select only single options from the group of options.

The focus() method is used to set the focus on the widget. It does not accept any parameter and does not return any value.

Syntax:

$('Selector').jqxRadioButton('focus');
