Thanks everyone! :o)
It looks like you're all saying the same thing. Using the class as an
identifier on the A tag is faster, and duplicate IDs are bad (which I
kinda knew already, but wasn't sure about the proper usage of the class
attribute). So I should stick with (in this case at least) using a class
to identify the A tags that I want to open in new windows.
I was avoiding using just $(".newWindow"), or $("#newWindow"), because
then jQuery has to search the whole document for that class or ID.
Whereas if I use $("a.newWindow") or $("a#newWindow"), it's faster
because jQuery then only examines the A tags, and nothing else. Am I
right in thinking that. I'm pretty sure I read something to that affect
on this list, as some point.
So I'll use $("a.newWindow").click(... as my selector. Does that sound
about right? Is it the best approach?
Thanks,
Chris

Yep, you’ve got it… tho if there are multiple links on the page you want

Yes, the class attribute isn't only meant to be a style sheet selector:
"The class attribute, on the other hand, assigns one or more class names
to an element; the element may be said to belong to these classes. A
class name may be shared by several element instances. The class
attribute has several roles in HTML:
* As a style sheet selector (when an author wishes to assign style
information to a set of elements).
* For general purpose processing by user agents.

Wow, I should get money everytime I post that quote on this list :-)
