Yes. But there is still the question of what the ID is going to be used
for. It is a bit depressing to recall the number of times I have seen
people reading - this.id - and then using the ID to look up a reference
to the element with - document.getele mentById -, without ever seeing
that - this - was (and must be) the value they wanted in the first
place.

Re: Dynamically building objects

Actually that question is now moot. I only needed to be able to get the
id because I needed the number in it. Rob's post helped tremendously,
and now I can use the DOM onclick property (who would have thought
wrapping it in function(){} would have done the trick?). Therefore, the
id isn't needed any more and everything is working swimmingly.

Thanks for the help, all.
