Steve,
That's a great explanation of the difference between these two methods.
Thanks so much! I'll probably use the first method to begin with. It is
easier for me to read, but that's probably because of my lack of
understanding anything about xpath. Something else I'll have to do some
reading on.
Thanks again! :o)

Chris,
I think you would need to test for performance differences unless John
or one of the other guys with more clue have some insight.
This works by creating a jquery collection of all td objects and using
each to iterate through them, then uses the if to filter them.
$('td').each(function() {
if (this.status == 'enabled')
$(this).click(function() {
// do something
});
});
Where as:
$("[EMAIL PROTECTED]'enabled']").click()
uses the xpath syntax to create a collection of just those td's that
have the attribute state='enabled' set on them, then applies the click()
method to each of them.
The first is probably a little more readable if you are new to jquery
and requires you to write more code. The later is probably more
jQuery-ish and I guessing it is a little faster, but I have not done any
testing and really have no facts to support the guess.

Thanks Klaus!
How does this syntax differ from other suggested syntax:
$("[EMAIL PROTECTED]'enabled']").click()
I'm curiout which is preferred, or faster. They both look clean enough to me.

Hi folks,
I have a table that represents a calendar. The user will be able to
select multiple dates from the calendar, but cannot select dates in the
past. I've written this code before using all _javascript_ and what I did
was add several additional pieces of data to the td tag other than ID or
CLASS. I added "state", "index", "status" and a few others. I accessed
these through f.calendarid.state... that kind of thing.
So I'm wanting to apply an event (probably several: click, mouseover,
mouseout) to only those td tags that have their state set to "enabled".
Not to *all* tds and not even to all tds with a certain class. ID alone
won't work. Is there a way to do this using jQuery? Something like:
$("td" status).click()... or whatever.
Thanks,
Chris
Hi Christopher, this could work:
$('td').each(function() {
if (this.status == 'enabled')
$(this).click(function() {
// do something
});
});
