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 renderer property is a callback function that is invoked whenever an item from the stated listbox is rendered. Moreover, this function is helpful in customizing the view of the stated list items. It is of type Function and its default value is null.

Syntax:

To set the renderer property:

$('#jqxListBox').jqxListBox({
    renderer: function (index, label, value) {
        var datarecord = data[index];
        return datarecord.firstname + " " + datarecord.lastname;
    }
});

 

To get the renderer property:

var renderer = $('#jqxListBox').jqxListBox('renderer');
