Using Tables and DHTML for Menus
Dynamic HTML can be used inventively in many ways. Here's a simple way
in which tables and DHTML can be used together to provide a menu function.
The technique may be used in a frameset, but to keep things simple, we are
going to use the table to control 'targets' in an inline frame (or IFRAME).
Here's how the technique works from a user's viewpoint.
From the authoring point of view, the menu list (in this case, a list
of external Web sites) is a table within a two cell table which also
contains the IFRAME. In our menu list table, each TR tag has an onClick,
an onMouseOver and an onMouseOut event, as follows:
The TR tag also has a "dummy" attribute of active, with an initial
value of false. So the whole tag looks like:
The effect of the routines is to provide the user with selection feedback.
When a selection is made, the selection is highlighted.
With some imagination, this basic effect can be used in a number of
situations. Good luck finding the appropriate situation!
