pass parameter to applet in another window

Is it possible to load an applet in a new window, and pass it a (dynamic) parameter? I can do it using javascript if everything is in the same window, but I can't figure out if it is possible to pass parameters to a different window. I am trying to add some functionality to a pre-existing web site, and my only option (that I an think of) is to use javascript.

I did finally find a javascript method. In my new window, I use document.opener.my_element.my_value. That gets the element I need from the parent window. I've been trying to figure this out for two weeks, and it turned out to be a simple one-line piece of code.
