what is the jquery opposite of this :not() command

jquery

Solution

Simply use the regular CSS attribute selector:

$('#advancedSearchWrap option[value=""]');

Problem

I am trying to get all option values that have no attribute value. So I want it to retrieve options setup like `<option value></option>` entries. I have `$('#advancedSearchWrap option:not([value=""])')` but what I need is the opposite. What is the opposite of this :not() command?
