Because this wasn't immediately obvious to me when I started out, here
is why:
The jQuery selector will always return an object. Eg:
typeof($("#doesntExist")) == "object".
That means if( $("#doesntExist") ) will evaluate true.
This is intentional - ie, if you do something like this:
$("#doesntExist").hide()
you won't get nasty js errors.
Cheers,
Hamish
