jQWidgets jqxTree checkItem() 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 jqxTree represents a jQuery widget that is used to display a hierarchical collection of items. To display the collection of items, we can populate from ‘UL’ or by using its ‘source’ property.
The checkItem() method is used to check a tree widget item. It accepts two parameter, the first one is item of object type and the second is state of boolean type. It does not return any value.
Syntax:
$('Selector').jqxTree('checkItem', item, state);Linked Files: Download jQWidgets from the given link https://www.jqwidgets.com/download/. In the HTML file, locate the script files in the downloaded folder.
