jQWidgets jqxListBox uncheckIndex() Method

Last Updated : 14 Sep, 2021

Introduction: 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 uncheckIndex() method is used to uncheck an item in the stated list when the checkboxes property value is set to true. Moreover, the index is based on zero, in other words, in order to uncheck an initial item, the uncheckIndex method must be invoked along with parameter zero. It does not return anything.

Syntax:

$("#jqxListBox").jqxListBox('uncheckIndex', index);

Parameter:

Index: The stated index of type number. The indexing starts with 0.
