<script type="text/javascript" src="../exscript/hideunhide.js"></script>
function unhide(divID) {
var item = document.getElementById(divID);
if (item) {
item.className=(item.className=='hidden')?'unhidden':'hidden';
}
}

<script type="text/javascript" src="../exscript/autoiframeresize.js"></script>

Code:

document.getElementById(id).height= (newheight) + "px";
document.getElementById(id).width= (newwidth) + "px";

You are appending 'px' to the height attribute, which it does not expect.
Try either of the following:

Using height/width attributes:

Code:

document.getElementById(id).height = newheight;
document.getElementById(id).width = newwidth;

Using CSS

Code:

document.getElementById(id).height = (newheight) + "px";
document.getElementById(id).width = (newwidth) + "px";

Also you can lose if(document.getElementById)

Logic Ali,

The script still does not work.
Thanks a ton for you're reply!

I have changed the .js and got rid of the "px". The outcome in my browser is the exact same as when before. When i combine the two scripts it only shows the iframe as i tiny little square.

Thanks for explaning the css bit.

function autoResize(id){
var newheight;
var newwidth;

{
newheight=document.getElementById(id).contentWindow.document .body.scrollHeight;
newwidth=document.getElementById(id).contentWindow.document .body.scrollWidth;
}

document.getElementById(id).height = newheight;
document.getElementById(id).width = newwidth;
}

Assuming your framed document has a strict doctype:

Code:

newheight=document.getElementById(id).contentWindow.document.documentElement.scrollHeight;
newwidth=document.getElementById(id).contentWindow.document.documentElement.scrollWidth;
