Hi
Completely ignore the non-standard nature of the noddy example
below.
I want to capture a mouse click in a frame from outside that frame.
Everything
I read online seems to indicate its something like the below but I
just can't get it to work. any ideas?

<script>
function Temp()
{
alert('hi')
}
function SetUp()
{
var myIFrame2 = document.getEle mentById("frame 2");
myIFrame2.attac hEvent('onclick ', Temp);
}
</script>
<body onload=SetUp()>
<form>
<IFRAME id=frame2 src="http://www.google.co.u k" width=100%

For which you would have to attach an event listener to the document
object within the IFRAME.

Find alternative reading matter.
<script>
function Temp()
{
alert('hi')
}
function SetUp()
{
var myIFrame2 = document.getEle mentById("frame 2");
myIFrame2.attac hEvent('onclick ', Temp);
There is a distinction between the IFRAME element in the containing
document and the frame object that contains the IFRAME's content. You
are attaching your listener to the IFRAME element. If it had borders you
probably could pick up clicks on those borders, but interaction with the
contents should not be expected to propagate to the containing document
in any way.
}
</script>
<body onload=SetUp()>
<form>
<IFRAME id=frame2 src="http://www.google.co.u k" width=100%

Unless you are working for google uk this is exactly the type of
situation that cross-domain/same-origin security is intended to prevent.
Monitoring user interaction with a page from a different domain, if
successful, would be open to considerable abuse. Consider monitoring
someone's interaction with the log-in page at their bank's web site, for
example (if onclick then why not onkeydown, and read their user name and
password as they type it in?).
You shouldn't expect this desire to be achievable (and your on-line
reading should have warned you of the issue).

open to suggestions here. Problem is I only work on IE as its the only
browser
we support, and naturally it doesn't support everything, has bugs,
etc. Also
most texts I find don't seem to go into this kind of detail, and
javascript is
very forgiving which makes things harder for me. Perl was the same
until I learnt about 'use strict' to make it catch more bugs.

reading should have warned you of the issue).
it did, noddy example again. The real example is all local and
accessed (for now) via http:/localhost/Temp/temp.html, hence fine
cross scripting wise. I'm sure that I've seen error messages from the
browser previously though about this or I would have remembered.
I've got this working now with something like the below
myIFrame1.conte ntWindow.docume nt.attachEvent( 'onmousedown',
function(){Fire Func('frame1'); })
I don't get an 'event' object though? How do you access the x,y
position of the mouse?
Thanks for your help

I can't say I have seen many people complaining that they won't help
with IE only stuff. Unless you mean Thomas Lahn, but he is not very
rational so you can safely disregard his opinion. It is true that IE
only stuff gets less attention, but that is mostly because writing for
one known environment is so trivial compared to cross-browser work that
it isn't very interesting (so of little entertainment value).
However, you could try posting to microsoft.publi c.scripting.jsc ript,
where IE only questions are the natural subject of the group.

That is exactly the sort of detail that needs to be presented up front
(it would, after all, have saved me spending any time on the subject at
all).

function(){Fire Func('frame1'); })
Are you looking in the right place for the event object? The event will
belong to the IFRAME's global/window object not the containing page's.
But the attached function, and the function it is calling, do belong to
the containing page so unqualified - event - and - window.event - both
refer to properties of its global/window object. If you want to write IE
only code then:-
myIFrame1.conte ntWindow.event
- should refer to the event object in that iframe. (Though I would
recommend accessing IFAMEs and frames through the - frames - collection
as the results are cross-browser (obviously works with IE as well); it
will require less reworking when IE's market share drops to the point
where even the most intransigent commercial sites realise they need to
accommodate other browsers.)

Talking about a js script which changes an iframe src through a "ref_to

Of course, knowing, I don't want (and can't n some cases where document

We have this script that currently shows a drop down menu when someone mouseovers a link, it pulls a div that sits off the screen and shows it to the user.
What i need to do now is i need to add an iframe to this, so it does the same . . . . but i'm a little unsure how to do it.
thanks.

Does anyone have any idea about how can we resize an IFRAME
