[thelist] Deselecting a select element in JS

[Hardacker, Andrew]

jeff, thanks for your well-considered reply. I hate to fan this up again but
I'd like to clarify a couple of points.

This W3 document, ECMA Script Language Binding, does specify that
selectedIndex is long (which, in most languages, is a signed integer capable
of holding a positive or negative value). There is no mention of valid
range; I made my assumption solely on Goodman's statement. And we know what
happens when we assume...

when the word netscape is used, i automatically think nn4.  want me to think
nn6?

Yes, sorry, Netscape6. At work (where I am allegedly doing productive work
even at this minute), our "lowest common denominator" for browsers is IE5.0
and Netscape6.2. (I forced Netscape6.1 out of the requirements.) Netscape6
may very well have a bug; without strong documentation on how this is
supposed to work, we may never know how it's supposed to work, although we
probably agree on how it _should_ work.

This bit of code was just a response to your original suggestion to loop
through the selected attributes.

fwiw, i don't see any point in referencing form elements via
getElementyById() as this unnecessarily breaks form interaction for older
browsers

Again, this was merely a test, not something I was coding for production,
only an effort to answer Olly's original question.

don't go just yet.

OK, but I should get back to work on my applet. btw, during this testing
Homesite5 crashed. Again. I've been using Homesite since its 1.x/$25
shareware days and I'm quite attached to it, but I would never call it
stable. A crash a day, even with version 5.
