jQWidgets jqxComboBox getSelectedIndex() Method
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 getSelectedIndex() method is used to return the index of the selected item. If no item is selected then it returns -1. It does not accept any parameter and returns the index number.
Syntax:
var index = $('selector').jqxComboBox('getSelectedIndex');
