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 disableItem() method is used to disable an item from the stated list. It has a parameter named item which is of type object or string and it does not return anything.
The following fields are used for the stated items of the list:
- label
- value
- disabled
- checked
- hasThreeStates
- html
- group
Syntax:
$("#jqxListBox").jqxListBox('disableItem', Item);
