You can't call a function on a diiferent domain, but you can change the
location of a window opened by your page.
Also, you must prevent further calls after the popup closes:

function odswiez()
{
if( !Mypopup.closed )
Mypopup.location='http://google.pl'; //.reload(true);
else
clearInterval(intervalHandler);
}

Both statements are true.
function odswiez()
{
if( !Mypopup.closed )
if (Mypopup && !Mypopup.closed)
{
Mypopup.location='http://google.pl'; //.reload(true);
Mypopup.location = Mypopup.location;
}

should also work.
else
clearInterval(intervalHandler);
}

However, assigning to .location is _not_ equivalent to .reload(true).
First, it can append to the window history; second, the resource will
be loaded from the local cache if feasible (therefore you need cache
control headers). reload(true) does neither.

Thanks for support. However I would like to force this popup to refresh
its current URL (user may navigate in it) - I do not want it to be hard
coded.

the solution with:

Mypopup.location = Mypopup.location;

does not working - I get exception error.

Maybe I should use vbscript ???

If it should be IE-only, you can try. But I doubt this will help.

No. You save a reference to the URL you opened in a Global scope and
then you set the location to that reference value:

var myURLVariable = "http://www.google.com";

function whatever(){
Mypopup.location = myURLVariable;
}

Then, you aren't stuck with not being able to read the URL of a window
from a different domain (which is why the location = location doesn't work).

Hi there,

I cannot read location property of this pop-up window - this is due to
cross-frame scripting security fix introduced in IE
(http://msdn.microsoft.com/library/de...g_security.asp)
Any ideas how to get it round?

Grzegorz

You missed the point.

This security feature is not only supported by IE, and certainly it is not
a "scripting security fix introduced in/by IE"; in fact, it originates from
Netscape 3.0 (JavaScript 1.1):

<URL:http://research.nihonsoft.org/javascript/ns30/ref_d-e.htm#68458>
(http://msdn.microsoft.com/library/de...g_security.asp)

Well, you can lower IE's security level of course, but I strongly recommend
against that. You could try to add the site to the Trusted Sites list and
see what happens. Or maybe you have better luck with VBScript (viable only
in an IE-only environment), as you suggested.

You have not told enough about the environment this is supposed to run in.
Maybe if you did, that would allow for suggestions of alternative
approaches.
