Access denied for location?

[Aaron]

Hi,

For some reason, when I create a new window using "myWin =
window.open(url)", and then try to get the location of the window using
"alert(myWin.location)", it tells that access is denied. How can it be
denied...it's a window I created...therefore, shouldn't I have access to
it's location property?

Thanks,
Aaron

The domain in the newly opened window is different from that of the
original window.

If the document in the window is not in the same domain then you can't
access it.
This is a security/privacy issue.

I understand what you're saying about security...but I'm reading O'Reilly's
Javascript: The Definitive Guide to learn this (which is supposedly a good
book), and there's a specific example where the location of another window
(another frame in the same set) is obtained and written into the a text box
of the current document. Why would this even be written if it's not
possible?
Also, I get the access denied message when I try to use a self-created "back
button" in one frame to control another frames location via it's history
object. This is in the book too, and it should work. Any ideas?

Thanks,

You believe *everything* you read?

The book is wrong.
