javascript permission denied to get property

[Wilco]

Hi,

I'm getting the message "javascript permission denied to get property"
on one of my sites.
I'm trying to do a 'getElementById' from an iFrame page. The iFrame is
trying to access information from the page that its loaded from.

The files are on the same server, so it can't be that.
It only occurs on one particular page.
This page is no different then any other page.

I've searched the newsgroup, but couldn't find a satisfying answer.
Can anybody help me out?

Most likely it's the Cross-domain script security restrictions (aka
"Same Origin policy") imposed to your script trying to access a propertly.

The files are on the same server, so it can't be that.

Same server but it could be different domain names.

Is it also fetched from the same server *name*?
E.g., is the "www." absent on the page URL used to load one of the pages?

You mean the same _domain_.

E.g., is the "www." absent on the page URL used to load one of the pages?

Just to prevent the "www" subdomain nonsense from spreading as a quick
solution to this problem, setting `document.domain' to the second-level
domain prior to access would simply avoid this problem:
