This should be simple, I made an IFRAME (with a src) and I want to assing the HTML-code inside the IFRAME to a variable, when I do this (using innerHTML), the variable always seems to be empty.

var myVar = top.frames['IFRAMEName'].innerHTML

now it says : "undefined". Do you know what that means?

Try this: parent.frameName.innerHTML

again undefined, here's my code:

<HTML>
<HEAD>
<TITLE> Garden of Fertility </TITLE>
<SCRIPT>
<!--
function interactive() {
var gu = parent.guest.innerHTML;
alert(gu);
}
-->
</SCRIPT>
</HEAD>
<BODY bgcolor="#FFFFFF">
<iframe id="guest" name="guest" src="http://server.scripthost.com/guestbook?tykhon" onload='interactive();'></iframe>
</BODY>
</HTML>

If you take off the innerHTML part, it returns "[object]." So it's probably because (1) it's on a different server, or (2) it's a PHP file.

As a matter of fact, the code works on my local server, but when I link to other servers, it does not. The page loads, and the innerHTML returns undefined. I believe this is because it is cross-server.

it's on a different server, that's true and it could be php (although I don't think so) but, when I use a html-file that's on my server I also get the alert: undefined ...

OK, here's what you do. Put the whole HTML file in a DIV. Then use parent.guest.myDiv.innerHTML

I can't, the page that's loaded in the iframe isn't mine, I can't change anything, I just want to get the HTML-code of a webpage so I can use it as a variable...

Is that possible?

Well, you can't get the innerHTML of an entire page unless you try setting something like this (http://geocities.com/god_loves_07/viewsource.html) to a variable (which is probably impossible). If you can't change the file or don't have access to it, then you might want to use a server side language to pull the source. Other than that, I don't think it's possible..

I agree, that's probably impossible and I have thought about using ssi, but I don't think my server alows using that language

other question, is it possible to extract the text and not the HTML-code by using javascript?

Neither innerText nor innerHTML work. I even tried text, but it doesn't have any attributes. You can try parent.guest.document.body.innerHTML

doesn't work either, so I assume it's impossible to get text from another page that's not on the same server, thanks a lot for all your help, i'll have to find another way...
