jQWidgets jqxComboBox val() Method

Last Updated : 24 Aug, 2021

jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful and optimized framework, platform-independent, and widely supported. 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 val() method is used to set or return the selected value. It accepts a single parameter value of string type which is optional, and it returns the string type value.

Syntax:

// Get the value
var value = $('selector').jqxComboBox('val');   or
var value = $('selector').val();

// Set the value
$('selector').jqxComboBox('val', 'New Value');  or
$('selector').val('New Value');
