Opera and IFRAME

@Xer0Apr 27.2003

I am having a problem accessing the innerHTML of an IFRAME in opera. I have read bits and pieces saying that this property does not exist in Opera, but is there a workaround? The code I am working with is thus:

function refresh() {
____frames[‘talksrc’].location.href = ‘include/talksrc.php?random=’ + Math.round(Math.random() * 10000);
_____document.getElementById(‘talksrc’).innerHTML = frames[‘talksrc’].innerHMTL;
_____// The above line is what I am having problems with
____setTimeout(“refresh()”, 5000);
}

Ideally I need a cross-browser solution, but Opera is the most important to get working.

@gil_davisApr 27.2003 — #According to their website, Opera 7 does indeed support both innerHTML and iframe. See http://www.opera.com/docs/specs/index.dml for more information.
<div id='talkdest' class='item'></div>

<iframe id='talksrc' name='talksrc'></iframe>[/quote]
So, are you trying to load something into the IFRAME and then move it to the DIV? If so,
document.getElementById('talksrc').innerHTML = frames['talksrc'].innerHMTL;[/quote]should bedocument.getElementById('talkdest').innerHTML = window.top.frames['talksrc'].innerHMTL;

@Xer0authorApr 27.2003 — #Sorry for my careless posting, I have tried what you mentioned, I get the following error.

Inline script thread

Error:

name: ReferenceError

message: Security error: attempted to read protected variable

IE returns 'undefined'.

Thanks for the opera link, I will give it a closer look.

On another trivial matter, Isn't 'window.top' assumed?

@gil_davisApr 27.2003 — #[b]Security error: attempted to read protected variable[/b][/quote]That usually indicates an attemt to access data from a foreign domain, which is a security violation. You are not allowed to access data from a different domain using Javascript. It is a security violation.
[b]Isn't 'window.top' assumed?[/b][/quote]Are you familiar with the definition of "assume"? It makes an ASS out of U and ME. In my experience, only IE is loose enough to allow you to get away with such short cuts. There are places where it would be required, and since I did not know the rest of your document's structure, I gave you the fullest syntax I could think of in order to give you the best chance of making Opera work. I'm no Opera expert, but I know that such an assumption will give Netscape heartburn, and possibly Opera as well.

@Xer0authorApr 28.2003 — #lol, that assume thing is good.

I've given up on the above method.

I'm trying a different approach:

<i>
 </i>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")? Any ideas?

@gil_davisApr 28.2003 — #Since I don't have Opera, I can only suggest you try this yourself:

&lt;script&gt;
 var e = document.createElement("script");
 for (var i in e) alert(i + " = " + e[i]);
 &lt;/script&gt;

See if one of the alerts saystype = You will see all the attributes that the script tag supports (I know it's a pretty long list in NS 6 and IE 5.5).

Perhaps you need to use the real DOM method setAttribute().e.setAttribute("type", "text/javascript");

@Xer0authorApr 29.2003 — #I have got it working with the following code:

<i>
 </i>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";

Thanks for all your help.
