jQWidgets jqxComboBox indeterminateIndex() Method

  • Last Updated : 22 Aug, 2021

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 jqxComboBox is used to represent a jQuery combobox widget that contains an input field with autocomplete functionality and a list of selectable items displayed in a drop-down.

The indeterminateIndex() method is used to set the checkbox item state to indeterminate based on their index. This method is applied when ‘checkboxes’ property is set to true. The checkbox uses 0-based indexing. It accepts a single parameter index of Number type and does not return any value.

Syntax:

$('selector').jqxComboBox('indeterminateIndex', index);
