Communications among windows

[dalhousi]

Hi all,

I have a little problem in Javascript. What I want to do is to communicate between two windows from different domains. I just need one function to be accessible from the other windows (that belong to different domains).

Is there any way around, like giving the function a "public" property or something like this so it can be called from different domains?

Thanks in advance,
Cheers,

If one is a sub-domain of the other, you can investigate the "document.domain" property. Other than this, you'll need a proxy of some sort.

Hope this helps,
Dan

Thanks for the reply Dan.

Actually the two domains are totally different. Do you know a good tutorial that explains how to use a proxy in Javascript?

Thanks,
Cheers,

You cannot use client-side JavaScript to write a proxy because of the security restrictions you've already come across. You would need to use server-side scripting to write one.

Whether you use JSP, PHP, or whatever else depends on what your host supports. You could even write it in server-side JavaScript although I'm sure there are better languages (then again, AOL write most of theirs in TCL, so JS isn't looking so bad after all ;-))

Hope this helps,
Dan
