Permission denied to get property Location.href

[Robert Mark Bram]

Hi All!

I have a piece of JavaScript that attempts to find the location.href
property of another window. For example:

contentWindow =
window.open('', 'someWindowName ');
var otherUrl = contentWindow.l ocation.href;

If it happens to find a window named 'someWindowName ' that currently has a
document loaded from some other host, the "contentWindow. location.href" code
triggers the following error:
Error: uncaught exception: Permission denied to get property
Location.href

I know I could put this code inside a try-catch. However, while I found this
works on IIS5.1 (my testing server), I also found that the version of
Chilisoft I have to use on the production server does not support
try-catch...

So my question is this: how can I avoid the uncaught exception in this case
without using a try-catch?

Thanks for any advice!

Rob,

Your quoted code looks like client-side script, so I'm puzzled as to what
possible effect your hosting server ASP environment might have. Use of
try/catch on the *client* is dependent only on the browser and the js
version it supports....

Of course you are right - I was thinking about the error message without
thinking about it coming from client side. Ignoring the try-catch issue, the
problem is the same: how can I avoid this error:
Error: uncaught exception: Permission denied to get property

Well, you can't change that, as you yourself write the document in the
other window is loaded from some other host, and the same origin policy
prevents script from one host to access properties of pages from another
host. If the hosts are in the same domain e.g.
host1.domain.tl d
and
host2.domain.tl d
then you can set
document.domain = 'domain.tld'
and the cross frame scripting should work, but if the hosts are in
different domains then there is nothing you can do, unless it is
Mozilla/Netscape where you could work with signed script.
