First off in javascript the () for function calls is mandatory - $('no-
items-msg').show just evaluates to a function object, you need $('no-
items-msg').show() to actually call it. secondly your javascript needs
to be inside <script> tags (there's a rails helper that will assist
with this, can't remember what it's called but it has javascript in
the name.
