DOM access to <OBJECT type="text/html" data="..." /> or <iframe>

[tilt]

Hello,

I use an object element to replace the iframe element in ie, like this:

[HTML]<object
id="x_obj"
data="http://.../"
type="text/html">

<iframe name="x_if" id="x_if" src="http://.../">
</iframe>

Alternative text (if object and/or iframe are not supported)

</object>
[/HTML]
With an <iframe> to support gecko browsers.

I want to retrieve the total height of the page loaded inside the object/iframe element.

With ie, this script works:

alert(document.getElementById("x_obj").object.body .scrollHeight);


And in gecko browsers (FF), the script should look like this:

alert(document.getElementById("x_if").contentDocum ent.height);


This script written for firefox doesn't work well as it gives a result of "0".

When I delete the object element from my script and just leave the iframe element, it works well.

Could anyone help me understand this strange behaviour ?

Thank you very much.

The iframe should not appear inside object tags. Gecko browsers do support the object tag.
