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.
