printing in URL

I have no experience in javascript...What I'm doing is using PHP and I was wondering if there was a way you can make javascript print out a word in a url? such as:
http://www.domain.com/page.php3?ani...erd&JAVASCRIPT= <javascript here to print out something>

Then I would just check to see if the variable $javascript is set and if it is, the user has javascript on. Then I can make it so that if javascript is not enabled, I can offer an alternative code for the pop-ups.

So can javascript print something out?

if you document.write() one of the parameters for the url its very existance will imply the javasript existance.

but if (navigator.javaEnabled()) is much easier?
