problem with opener.location.assign

[Venkatesh]

Hello all,

We have a micro site that is getting opened inside a popup window from
some external main site (the domains of our microsite and main site are
different) ...

I need to support the following functionality: After the user is done
surfing the pages on our site and user clicks the close hyperlink
(present on top of all of our webpages), the opener window's location
needs to be reset to some given URL ....

I had a small javascript code for this, where i have written:
window.opener.location.assign("<url>"); .

My problem is that this line of code is throwing an exception saying
"Permission denied to access method location.assign" ...

Can anybody help me and let me know why am I getting this exception?
and how to overcome this problem?

Thank you,
Venkatesh

Cross domain security. You may not access the vast majority of the
browser's object model from a script originating in a different domain.
That includes the reading of the - loaction.assign - property implied
in the attempt to call it.

and how to overcome this problem?

Generally you can access the - opener.location - property (but not its
contents) so you could try writing the URL directly to that property
(indeed that is the normal cross-browser method of navigating a browser
window, and messing about with - assign - methods should never have
even been proposed to you). I.E:-

opener.location = '<URL>';

Hello Richard,

Thanks for your suggestion ...

opener.location = url works for me ...

Actually I was of the impression that if we directly URL to
opener.location, that would clear browser history ... But seems like
that is not the case.

I'm now wondering what is the exact use of the assign function?

Thank you,
Venkatesh
