jQuery: select all elements of a given class, except for a particular Id

Use the :not selector.

$(".thisclass:not(#thisid)").doAction();

If you have multiple ids or selectors just use the comma delimiter, in addition:

(".thisclass:not(#thisid,#thatid)").doAction();

Or take the .not() method

$(".thisClass").not("#thisId").doAction();
