Hi,
I want to access the properties of an IFrame but seem unable to get access
to the IFrames document body.
<html>
<body>
<iframe src="test.html" id="IFrame"></iframe>
</body>
<script>
var f = document.getEle mentById('IFram e');
f.document.body .innerHTML = "This is another test";
</script>
</html>
This writes to the main document not the IFrame.
I am doing something very basic wrong but cannot work out what. (I do know I
should be doing a open/write/close rather than an innerHTML but this is just
for testing access to the contained IFrames properties)
Help,
Aaron

Of course.

You are obtaining a reference to an HTMLIFrameEleme nt object, representing
an `iframe' element node in the document tree. By modifying the former's
proprietary `innerHTML' property, you modify the content of the `iframe'
element. This content is displayed only if the `iframe' element is not
supported.
(I do know I should be doing a open/write/close rather than an innerHTML
but this is just for testing access to the contained IFrames properties)
You need to access the document object of the IFrame resource instead.
Proprietary: window.frames['IFrame'].document
(preferably with `name' instead)

Properties are accessable but content is not on IE 6, previous versions
allowed access to the contents.
Firefox allows access to the contents of an IFrame, but IE6 does not.

Try it and please send me some code that disputes this !
I would be most greatful if you can prove me wrong.

I seem to be able to read but not modify innerHTML.
I'll modify my statement :-
IFrame content is readable but not modifiable from the parent
window.
Do you agree ?
Thurther :-
<iframe src="document.h tml" name="IFrame" id="IFrame"></iframe>
<div id="sourceViewD iv"></div>
document.getEle mentById("sourc eViewDiv").inne rHTML =
window.frames['IFrame'].document.body. innerHTML;
window.alert(wi ndow.frames['IFrame'].document.body. innerHTML);
The first script line fails but the alert works.
Am very confused,
Aaron

That would depend on what you call "IFrame content". Try the URL again
(I modified the document). The first and third button do work for me in
IE 6.0 SP1 [Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)]. All
buttons work in Firefox 1.5.0.1 [Mozilla/5.0 (X11; U; Linux i686; en-US;
rv:1.8.0.1) Gecko/20060313 Debian/1.5.dfsg+1.5.0. 1-4 Firefox/1.5.0.1].
Thurther :-
<iframe src="document.h tml" name="IFrame" id="IFrame"></iframe>
<div id="sourceViewD iv"></div>
document.getEle mentById("sourc eViewDiv").inne rHTML =
window.frames['IFrame'].document.body. innerHTML;
It does not appear as if you were attempting to modify the IFrame
document content here.
window.alert(wi ndow.frames['IFrame'].document.body. innerHTML);
The first script line fails but the alert works.
ISTM either you have mixed up the sides of the assignment, or you have
described the wrong problem. If the latter, you should make sure that
you are operating on a Valid document first[2], and that
document.getEle mentById(...) returns an element object reference.[3]
"The first script line fails" is no error report.[4]

No just reading its text into a div. window.alert(wi ndow.frames['IFrame'].document.body. innerHTML);
The first script line fails but the alert works.

"The first script line fails" is no error report.[4]
It was returning null.
Your example shows the modification of IFrame innerHTML working.
Looks like it is a timing error in my code. Doing mods explicitly to the
IFrame on loading the parent document causes a 'null' value for that
documents body.
Many thanks for your help Thomas,

Can anyone point me at a resource to explain how I can do this?

Alright, this is very strange. I call a javascript function in my page

page completely loads and access the iframe through a click event
everything works fine.
I'm trying to set some of the iframe's properties on page load before
the page gets rendered. Can I do this? I even tried to acess it in the
Pre Render event and that does not work either. Thanks for help
