jQWidgets jqxListBox indeterminateIndex() 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 indeterminateIndex() method is used to indeterminate an item in the stated list whenever the checkboxes property value is set to true. Moreover, the index that is to be used here is based on zero, in other words, in order to indeterminate the first item of the list, the ‘indeterminateIndex‘ method must be invoked along with index zero. It does not return anything.

Syntax:

$("#jqxListBox").jqxListBox('indeterminateIndex', Index);

Parameters: This method has a single parameter as mentioned above and described below:

  • Index: It is the stated index of type number.
