How to get tagName for VML object?

Question

VML objects in IE8 throws exception when I try to access tagName attribute. Is it possible to get it in some other way?

Sample code that raises exception:

function clickCallback(event) {
  var target = event.srcElement;
  target.tagName; // Here exception raised
}

Answer 1

Found the answer: instead of tagName, nodeName attribute should be used.
