Firefox: Resize iframe according to actual content

Question

I have an iframe and I am trying to resize it based on its actual content (like so I dont get any scrolling). I have tried the following:

alert(document.getElementById(iframe).contentWindow.document.body.height); alert(document.getElementById(iframe).contentWindow.document.body.scrollHeight); alert(document.getElementById(iframe).contentWindow.document.body.offsetHeight);

None of those work. iframe contains the id of the iframe. The last two lines work in Chrome.

Any help would be really appreciated.

I think you cannot access the properties of the document in the iframe from the outside document, but you can do it the other way: access the properties of the document in the iframe from within that document itself, and then call a function in the outside document. This outside function would then do the resizing, as described here: Resize iframe height according to content height in it
