jQWidgets jqxNavigationBar initContent Property

Last Updated : 29 Oct, 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 jqxNavigationBar is used for representing a jQuery widget that has header and content sections. On clicking over the header, the content will be expanded or collapsed accordingly.

The initContent property is used as a callback function that is called when an item’s content needs to be initialized. Here the index argument shows which item is initialized.

Syntax:

Set the initContent property:

$("Selector").jqxNavigationBar({
    initContent: function (index) {
        $("#jqxButton").jqxButton({ 
            $('#jqxbutton_for_initContent')
            .on('click', function () {
                $('#jqx_Navigation_Bar')
                    .jqxNavigationBar('disable');
            }); 
        });
    }
});

Return the initContent property:

var initContent = 
    $('Selector').jqxNavigationBar('initContent');
