thank you Aaron. In fact, what i'm trying to do, is to create a variable in case an element exists. "undefined" will do :)

According to Firebug typeof $('form').attr('action'); is "undefined" in both cases. FYI: jQuery() returns and empty jQuery object when no elements match the selector. If you try to call a method on an empty jQuery object, then nothing will happen (because there is noting for jQuery to work with).
