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.

Answer 1

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
