Thanks Troy,
That's a a nice bit of JS, but it's not quite what I'm looking for. It
accesses element values within another frame. I'm trying to get the entire
frame contents where there may or may not be elements defined and the frames
both have the same parent frame.
How about this: Is it possible to load a variable or DIV element with the
contents from a url?
ie var txt = someFunction(parent.otherFrame.location);
or
document.write('<DIV>'+contentsOf(someURL)+'</DIV>');
Thanks
Dave
