Toggling: function(sender,args)
sender. Event source.
args. Event information.
The Toggling event is occurs on expanding or collapsing a tab.
To execute the example enable the hyperlinks to the PP.js libraries and the table of the PP.css visual styles. Create a navigation panel named NB that has two tabs. Add a handler for the Toggling event:
<script type="text/javascript">
var NB = new PP.Ui.NavigationBar({
ParentNode: document.getElementById("NB1"),
Width: 200,
ShowBorders: true
});
NB.addItem(new PP.Ui.NavigationItem({ Content: "1", Title: "1" }));
NB.addItem(new PP.Ui.NavigationItem({ Content: "2", Title: "2" }));
NB.getItem(0).Toggling.add(function (sender, args) {//handler for the Toggling event:
NB.getItem(1).setEnabled(false);
});
</script>
After executing the example on expanding the first tab panel the second tab becomes unavailable for the user.
