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 jqxBarcode is used to indicate a widget that can display various forms of bar codes. 

The value property is used to set or return the value of the displayed QR code. It is of string type and has no default value.

Syntax:

Set the value property.

$('Selector').jqxBarcode({ value: "Barcode" });

Return the value property.

var value = $('Selector').jqxBarcode('value');
