How to save Javascript variable between frames?

Question

I have a javascript variable called "myvar" in two different frames (frame1 and frame2). I need to take the myvar in frame1 and set it as the value of the myvar in frame2. How do I do this without an external script?

That having been said, you should probably be asking "why am I using framesets?"... It's 2013 man. — BenM

What do old PCs have to do with the use of old web technologies? Isn't that the whole reason? Harness the power of the server? — BenM

If the variable is in the parent, use:

window.parent.varName

If it's in another frame, go through the parent, then to the frame:

window.parent.frameName.varName

How do you change the varName? could you use an example using "myvar" as both variables?

window.parent.frame1.myvar = window.parent.frame2.myvar

This only works for same scheme domains:port. As of same domain policy. Just to be curious.

are both frames on the same domain? sub domains on the same TLD?

Sorry, my bad. I needed to pass two variables. I only passed one. It's working now. Thanks.
