How to clear the content of an IFRAME

Jakob...

You could always set the style display: none to it...it wouldn't actually "clear" the iframe, but it would hide it from view.

document.getElementById(iframe).style.display = none; should do the trick...

Past that, loading the iframe with a blank document would be about the only way to "clear" it out.

Jakob, did you find a solution to this?
Here's another possibility:
If "windowRef" is a reference to the window object of the frame you want
to close, then
windowRef.document.open();
windowRef.document.close();
should do it.

Ok, theDude,

so if I have

<iframe id="iframetest" src="example.html"></iframe>

and
<script language="javascript">
x = document.getElementById("iframetest");
[...]
</script>

how do I get the reference to the window object of that iframe in order to clear it with the "open/close" sequence?

I have actually found the answer myself in the mean time.

First, give the iframe a name attribute instead of the id:

<iframe name="iframetest" src="example.html"></iframe>

Then access it in javascript like this:

x = window.frames["iframetest"];
(Or in IE just like this: x = iframetest)

Then you can do like theDude suggests:

x.document.open();
x.document.close();

But this more simple method also works:

x.document.body.innerHTML = "";

These solutions have been tested in Firefox 1.5 and Internet Explorer 6.
