Returns whether a particular treeview node has been loaded. Accepts a jQuery object, DOM Element or a path identifying the node.

Loading is normally done when an item is expanded for the first time, regardless of whether it is bound to a remote or a local data source.

<ul id="treeview">
    <li>My Project
            <li id="someid">js</li>

<script type="text/javascript">
    jQuery(function ($) {
        var treeview = $("#treeview").shieldTreeView().swidget();

        // prints false at this point
        console.log(treeview.isLoaded([0, 0]));
