1) check the battery in your watch; it's so not 1997 anymore. :-)

That line looks resurrected from a seriously ancient tutorial -- read
up on EventListeners to understand why it's a poor approach, and
how you should be invoking your functions.
2) defensive coding: you can either test first to see if there is an
element with the ID "tabs" or you can wrap the whole thing in
a try/catch block.

3) Either way, it's strictly a JS question and has nothing to do with
Rails.
