This is incorrect. In IE, events are executed in the window scope, so
when you do this.tagName, it is equivalent to doing window.tagName.
You must get the target element from the event itself, as I suggest
here:

You can alternatively specify the scope in which the handler should
run. YUI does this. You can see how they are doing it in their source:
