Cross-subdomain javascripting.

[Connell]

Hi,
I have two subdomains, say A.domain.tld and B.domain.tld.
I have put an html file on A which opens an iframe of a page from B.
Is there any way that I can specify (in either file) that I want the
page on B to be able to call functions on the A page (which, to my
knowledge so far is impossible due to the security restrictions
browsers place on the DOM).
As in I want to be able to say on A "let pages from B call my
functions".
And then on B say "parent.somefunction();"

Thanks
Connell

If both documents set the property
document.domain = 'domain.tld'
then access across subdomains of that domain should be allowed.
