Event hierarchy?

[Robert Mark Bram]

Howdy All!

If I write an image tag inside an anchor tag like this (for a rollover):
<A HREF="#" onMouseOver=".. ." onMouseOut="... ">
<IMG SRC="...">
</A>

Does the mouse event generated on the IMG tag get sent to the HREF tag's
handlers because the IMG tag has no handlers?

What happens if both tags have handlers?

IMG tag doesn't have any ONMOUSEOVER or ONMOUSEOUT event handler, which
is why you need to wrap the image in a A tag.

The event will be passed to the Link object, NOT to the Image object.
Simple proof of that is that any reference to "this" in the event
handler refers to the Link and not to the Image.
