$('.left_selected') returns always true, because if there's not a
matching element, $('.left_selected') is an array (not null) with
length = 0.

The problem here is that neither of your expressions can EVER evaluate
to false. Even if no actual DOM element is selected, you still get an
empty (jQuery)array.

Hi Andrea,
it's really a matter of true or false. The attr() method returns a
string and so if it returns an empty one, it's evaluated as false and
the part after the || operator is then taken. You use jQuery wrapper
on both sides of the || operator and jQuery wrapper always returns
something
