Actually, the question I'm really looking for is -- if I have a piece of
functionality on my website -- say a popup window -- that occurs on a
certain page. I use javascript to open the window. If a user has a browser
that does not handle javascript or if a user has disabled javascript I want
to use alternate methods to popup the window (like Target="_NEW" for
example).
So I declare a javascript function at the very top of the page to popup the
window, but how do I know if that javascript function will be executable on
a particular users' browser. For now what I do is check if a user's browser
is less than IE 4.0 or Netscape 3.0 and if so, use the alternate link. But
if the user has Opera which does accept Javascript or if the user is using
Netscape 4.0 with JavaScript disabled, then I am out of luck.
Any more recommendations?
thanks,
J

This is as much as you'll ever need in most cases. The point of <noscript>
is to provide alternative content for Javascript-compatible browsers which
happen to have support for it turned off. It (rather obviously) has no
relevance for those few remaining browsers that don't understand
Javascript at all, because by definition they won't understand <noscript>
any more than they'll understand <script>. Which is why scripts should go
inside comment codes (as above), so that those browsers will just ignore
all the material inside the tags it doesn't understand. Theoretically :)
