javascript event originalTarget

Returns a reference to a node that Netscape 6 internally treats as the genuine first target of the event. By and large, this information isn't helpful to DHTML scripting, because it dives into the internal construction of certain elements (e.g., an input element of type text has a div element nested inside of it, but the DOM node tree does not see the div element as a child node of the input element). For many events and event targets, the target and originalTarget properties reference the identical node.
