The question on all of this is usage - and I don't know how clear it
was stated.
The selectors everyone has put up are valid, but not necessarily for
the usage.
<<I have provlem with selecting
a first link in code below. Can you help me how how it should look
like jQuery code and also for case, if Home will not be a link, so
"Rules" will be a first link.>>
So the issue is to remove only the first link. $('#menu li:first a)
will only select the anchor inside first list item. Perfect until you
put home inside that with no link. Then nothing matches that criteria.
$('#menu li a:first') matches up to the first anchor tag inside a li.
http://test.learningjquery.com/selector-bug.html Proves the theory.
If you did a selector of 'p' it would affect ALL of them, right? So
there are 7 anchors in the first position of an li, and 0 in the
second. Jquery 1.3 didn't create a bug - it fixed a selector problem.
The only true selector is to use $('#menu a:first'). It will select
the first anchor and only the first anchor.
It all just problem with sloppy selectors in the past. They cleaned it
up and got it right. I would suggest we make the adjustments.
