236547 - Cannot attach events to IFRAME if it is created with createElement function

Status: UNCONFIRMED

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Jorgen Horstink]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007

If you take a look at this URL:

http://www.nextavenue.com/mozilla/bug/iframe/

You see two examples; one does work fine and the other does not. The only 
difference is how the IFRAME is created. If you take a look at the code it will 
become clear immediately.
Attaching events to an IFRAME seems not to work if it is created with DOM 
functions.

Reproducible: Always
Steps to Reproduce:
1. Create a new IFRAME element
2. Append it to the body
3. Try to Attach any event

Actual Results:  
You can click as much as you want, the event will not be fired...

Expected Results:  
The event should have fired

There is no easy workround since I must create the IFRAME with DOM functions...
I am reprogramming my Editor and want to make it Mozilla compatible.

Dupe of bug 231578??

The problem is that the document you're adding the event handler to ceases to
exist.  When you create the iframe, it starts an asynchronous about:blank load.
 you attach the listener, then the load finishes and replaces the document.

Simply changing that line to:

setTimeout('document.getElementById("frame").contentWindow.document.addEventLister("mousedown",
foo, true)', 0);

Makes things work.

An no, it's not a dup of bug 231578, since the event listener is NOT set on the
iframe.  It's set on the .contentWindow.document of the iframe.

I figured out there is no problem if you change the ID to: "blabla" instead 
of "frame"...

Odd, is FRAME a prohibited keyword?

I have found a solution; attach the events when the onload event fires :)

Using the setTimeout is not a solid solution (I tried, now and then the problem 
still occured)

Hi!

I am experiencing a simular bug!!!

If I move or replace an Iframe Object, I can not access javascript functions in the iframe document anymore!!!

When moving an outer object (div) in wich the iframe is placed you can do it one time and it will work, but if you move the outer object div again it will fail!!!

here is the site on wich I am testing: www.dwergpapegaai.com

You can post a message, and then try to reply to the message you posted (message is implemented via AJAX). It won't work, in IE all possible solutions work fine!

Please help!
