The link to the above .js file is broken. Are you able to restore it?

this pulls up an error on page in ie 8, if the remote iframe is called without name="surveyFrame" id="surveyFrame" being added to the local iframe field.

so not good if you need to call the remote iframe and dont want to have it auto resized. I need some iframes resized, i need some left alone so get the below error on page if I dont add the top attributes to every local iframe field.

Message: 'null' is null or not an object
Line: 26
Char: 2
Code: 0
URI: http://www.mydomain.com/resize.js

regards

So, will this method to resize external iframes still work on the latest ie 8 and firefox?

Im no professional scritper though I think this script could be my answer to my prayers,

though wasnt sure if it was still compatible?

many thanks

First off, thanks a ton! I have been trying to find a solution for days.

I did want to raise one issue (which I resolve below). Cross domain security issues will still arise if a user access your site with http://somedomain.com/parentPage.htm, and your child page uses loadHiddenIframe("http://www.somedomain.com/hiddeniframe.html");, or vice-versa.

To resolve this, here is what I came up with (in 3 steps):

1- CHANGE resize.js to the following:

function QueryString(key)

{

var value = null;

for (var i=0;i

Hello JohnW,
There is a tiny tiny problem. The download link http://uploadingit.com/files/914996_sbtif/resize.zip doesn't work any more (file not found).
Thanks

There were some errors in my code. All code fragments and downloads have been corrected.

Tested fine on IE 8 beta 2. See Notes above re browser differences.

Sorry for the double-post. I re-read the comment again, and if the child iframe uses a hidden frame to load a page on the parent's domain with the querystring, and that hidden page tells the parent page via javascript the child size, that may work, but it would be good to test in IE 8 beta 2 to confirm.

Oh, OK. It sounds like then the parent frame is telling the child iframe the size. I thought it was a technique for the child to tell the parent page how big the child needs to be.

So that should still work, sorry for the confusion.

the misunderstanding may be mine, as i'm new to this.

but i believe the technique uses query-strings (which get passed to the server, and are preceded by a question-mark), and not fragment id's (which do not get passed to the server, and are preceded by the # pound-sign "hash-mark").

http://andrew-ford.com/stw/node63.html

here's the script-line which loads the hidden iframe:

iframe.src = path + '?height=' + height;

so maybe i was incorrect to reference the tagneto article.

is support of query strings going to change?

nospam@example.com (James Burke) — Wed, 05 Nov 2008 20:08:45 -0500

I was under the impression the technique above uses fragment IDs (the #part of an URL) to communicate across domains, and that setting the location of a parent or child with a new #value is how the technique works. So in that case, querystring parts (the ?name=value parts) are not involved?

If that is the case, Microsoft has placed new limitations on setting the parent (and child?) locations with different #values that may not work as expected in IE 8. I am not aware of the details, but postMessage was mentioned as the way to work around those issues.

I think the issue is the permissions on parent/child frames changing urls with fragment IDs in other frames.

I could be misunderstanding the technique though.

Aren't URL query-strings a critical feature of billions of websites?
