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 backgroundColor property is used to set or return the background color of the displayed QR code element. It is of string type and its default value is “white”.

Syntax:

Set the backgroundColor property.

$('Selector').jqxBarcode({ backgroundColor: "red" });

Return the backgroundColor property.

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