Opera and IFRAME

Thanks _adios, but I am already using Opera 7.
that line should be:
document.getElementById('talkdest').innerHTML = frames['talksrc'].innerHMTL;

Opera's website (http://www.opera.com/docs/specs/) claims it suppports innerHTML, however I get the following error:
Inline script thread
Error:
name: ReferenceError
message: Security error: attempted to read protected variable

I see you have

document.getElementById('talksrc').innerHTML = frames['talksrc'].innerHMTL;

Why are you assigning the frame its own HTML?

Only IE with a file with extension .HTA and <iframe APPLICATION="yes"... would allow that code anyway
which probably should be

document.getElementById('talkdest').innerHTML = frames['talksrc'].innerHMTL;

duh... of course
But I guess you mean
frames['talksrc'].document.body.innerHTML

Oops, didn't notice he was loading that into an element...

I am loading the file using a relative path name, so wouldn't the browser realise that the page is in the same domain? I can access the 'document' in ie only, but nothing further.

Perhaps there is another way to approach the problem. Is there another way to load a file using javascript? Could I make a php file rather than displaying in the iframe, to dump to a file and then load that using js?

Or could I dump a .js file that will reload the div and then dynamically include that?

I'm going to go and try the latter method now, I'll post my findings here.

I can't get either of those methods to work.

I'm trying a different approach:

function dhtmlLoadScript(url) {
     window.top.frames['talksrc'].location.href = 'include/talksrc.php?random=' + Math.round(Math.random() * 10000);

     var e = document.createElement("script");
  e.src = url;
  e.type="text/javascript";
  document.getElementsByTagName("head")[0].appendChild(e);

  setTimeout("dhtmlLoadScript('include/talk.js?random=' + Math.round(Math.random() * 10000))", 2000);
}


dhtmlLoadScript('include/talk.js?random=' + Math.round(Math.random() * 10000));

talk.js is rewritten by talksrc.php everytime it is called.
This method works in IE (yay!), but Opera raise a syntax error on the 'e.type = ...'. If I comment it out I get other syntax errors about e not existing. Does Opera not like createElement("script")?

I'm a little out of my depth here, but I think this method could work. I hope all that made sense :)

Originally, I wanted to refresh the IFRAME (This works no problems), and then transfer the document inside the frame into a div ('talkdest').

Now, the reason I refresh the IFRAME is to make the server create a new .js file, which I can then dynamically include into the page. I realise that this is not very efficient, but I can optimize it later so that only new content is downloaded.

Let's see if I am following what you are saying...

If you load talksrc.php, that in turn loads talk.js ... right?

So if you call

talksrc.location.href = 'include/talksrc.php?random=' + Math.round(Math.random() * 10000);

Should that not (re-)load the javascript file too? Does that happen, or are you are experiencing a problem with that?

Then, you want to read the contents of that iframe into a div...  it looks like if you join the various suggestions above together you should be using something like:

document.getElementById('talkdest').innerHTML = frames['talksrc'].document.body.innerHTML;


Is this correct?

 

Opera does not like frames['talksrc'].document.body.innerHTML; (Protected variable)

I have got it working with the following code:

function dhtmlLoadScript(url) {
  window.top.frames['talksrc'].location.href = 'include/talksrc.php?random=' + Math.round(Math.random() * 10000);
  setTimeout("dhtmlLoadScript('include/talk.js?random=' + Math.round(Math.random() * 10000))", 3000);
}


dhtmlLoadScript('include/talk.js?random=' + Math.round(Math.random() * 10000));

And placing this in into the IFRAME inside script tags:
window.parent.document.getElementById('talkdest').innerHTML = "content";

Thankyou all so much for your help, is there a way I can give you all points? I'm new here, I don't know how the whole system works...
