Discussion
The beforeChange event fires before a tab or accordion pane is opened. If this event returns false, the action is cancelled.
If the Tab control is configured as a 'Tab' type, your code can reference oldTabNumber and tabNumber.
If the Tab control is configured as an 'Accordion' type, your code can reference targetTabNumber and state. To see what's in the state object, add the following code to the event:
alert(JSON.stringify(state));
