FF: event.pagex and event.pagey.
General: both have event.clientx and event.clienty properties.

Add event

AttachEvent (" onclick ", func1); Element. AttachEvent (" onclick ", func2) so that both func1 and func2 are executed.

General: div1.getattribute (" value ").

Parent, child, and delete nodes
IE: parentElement, parement. Children, element.romovenode (true).
