jQWidgets jqxListBox beginUpdate() Method
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 beginUpdate() method is used to block the ListBox’s interpretation. Moreover, it is generally utilized when several elements required to be either inserted or else eliminated dynamically.
