FAQ Topic - Why do I get permission denied when accessing a
frame/window?
-----------------------------------------------------------------------
In the normal browser security model, a script may only access the
properties of documents served from the same domain or IP address,
protocol, and port.
Any attempt to access a property in such cases will result in a "Permission
Denied" error. Signed scripts or trusted ActiveX objects can
overcome this in limited situations.

No. I am much too ignorant of JavaScript to do it.

While I know a lot more than I did not so long ago, I am still

Is there no one who knows JavaScript well who could do it? I
would be fine submitting some suggestions (from my fairly newbie
perspective).

The problem in the past has been that maintainers have known JavaScript
too well, while being relatively poor at communicating to the sort of
people who are needing help.
An example from my own experience as a newcomer : I asked about writing
to a page which was already being displayed. In those days, one might
need to use document.layers or document.all or document.getElementById,
for the general case of "labelling" and writing to a general location.
The then maintainer offered a complex piece of code which generated a
browser-dependent function to get a reference when called by another
function F expressed by a string; he said to use <div ID=anID></div> in
the HTML and F("anID", S) in the script to write string S into that div.
It worked, of course; and went into the FAQ; it is now simplified into
Section 9.4.
But it did not say, and 9.4 does not explicitly say, that the solution
to the task has two distinct consecutive parts - getting a reference to
the element, and setting the value` of the element. It did not
explicitly say that the solution could be used for most types of
container element. It did not mention that such a reference could be
obtained in other ways such as forms[3] or this.form.Btn1.
The two parts, separated but joinable, are far more widely useful than
the united code.
Now see <http://www.merlyn.demon.co.uk/js-faq-u.HTM#MaWP> ff.

Can we agree that being an js-expert is not necessary and sometimes even
