Ah, OK, so in your case, retrieving the NativeEvent's EventTarget, cast
()ing into an AnchorElement (well, first verifying that it *is* an "A"
element by checking its getTagName(), and walking the tree up until
the HTML widget's getElement() or an "A" element is found) then
calling AnchorElement#getHref() should give you what you want. Then
get the indexOf("#") and then the substring(hashIndex) to pass it to
History.newItem(...).
You'll find similar code walking up a DOM tree in
HTMLTable#getEventCellTarget (or a similar named private/protected
method, this is from memory), in this case it's looking for "TD"
elements.
