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 jqxForm represents a jQuery form widget that contains textFields, textArea and password fields, etc which helps us to store data in the backend of our application.

The getComponentByName() method is used to get the component information by using its name. It does not return any value and takes the component name as the parameter.

Syntax:

$('Selector').jqxForm(
    'getComponentByName', 'componentName');
