The .on() selector parameter doesn't work with :not(:first) selector

I'm using the .on() selector in this manner:

$(document).on("click", "#users_table tr", function (event) {

and it works.

If I add the :not(:first) (which works in any other selector usage), the event is not triggered on all rows (instead of not triggering only on the first row)

$(document).on("click", "#users_table tr:not(:first)", function (event) {

Confirmed on latest Chrome/Firefox. Improved testcase

As a temporary workaround, you can use tr:gt(0) instead.

You should also use delegating instead of live:

Looks like two problems here. One is with the POS regexp in .is(), it isn't sending :first to the positional selector route. Then there seems to be a bug in Chrome where a selector with :first in it returns false rather than throwing, which is should since that's a non-standard selector.

However, using positional selectors in a case like that is a very bad idea because it is much less efficient than a standard selector. It has to select all the elements that apply and see if the one you are asking about is in that set.

You can use :first-child instead and it works.

False alarm on the Chrome bug, it seems to be working fine. We're working on the regexp issue.

Dave and I discovered that we should origPOS here.

Use Sizzle.Expr.match.globalPOS for identifying POS selectors in traversing. Fixes #10970.
