Hello,
I'm writing a function in a global script that will apply focus to the first
visible enabled form field on a page. I'm using the following jQuery
expression to find the control:
$('#mainContent
:input:visible:not(:checkbox):not(:button):not(:submit):not(:image):not([EMAIL
PROTECTED]):first')
This works exactly as expected, but unfortunately it's quite slow in IE 7
when there is a fairly large amount of HTML (about 12 seconds on a page that
contains 2 select lists with several hundred options each). I had assumed
that the ":first" qualifier would cause the search operation to stop after
it finds a match, but that doesn't seem to be the case. And the problem
doesn't seem to be with any of the other specific qualifiers I'm using;
"*:first" is equally slow.
I think I need to do this the long way, traversing the DOM and checking all
the conditions manually, just so I can stop when a match is found. Unless
anyone can think of a way I can accomplish this and still take advantage of
jQuery's coolness in some way?
Thanks in advance,
Todd
