67954 - JavaScript for changing an image doesn't function

Status: VERIFIED DUPLICATE of bug 22820

(Core :: DOM: Core & HTML, defect)

Description

[Andreas]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
BuildID:    Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; Preview)

I'm developing for a big Website-project and I want to change an image with 
an "onError"-event, cause thei image isn't stored. For that case, I want to 
show a default image. My code is working in IE and Netscape 4.*, but not in 
Netscape 6/Beonex and so on. I write my script down below, so that you can see, 
what I mean. The crazy thing is, when I give out "alert's" for showing the 
right path befor and afterwards the change, I can see the image for a short 
time on my site, but when I say "ok" to the alert, the image is gone. In 
the "window.Timeout"-command I tried to show me the path of the image.src 
again - it's the right path to the dummy-image.
Well I do not know what's going wrong there, but it would be very kind of you, 
when you could help me.


Reproducible: Always
Steps to Reproduce:
1.just put the script into any site and take two pictures of your own.
2.
3.

<div id="table_righttop" class="righttop">
		<script language="JavaScript">
<!--
var ueb1
var alternate1
function change(ueb){
ueb1 = ueb;
//alert(ueb);
alert("here I am: " + ueb.src);
alternate = new Image();
alternate.src ="/images/user/user_dummy.gif";
ueb.src= alternate.src;
alternate1 = alternate;
alert("here I am: " + ueb.src);
window.setTimeout("alert(ueb1.src); ueb1.src= alternate1.src;", 2000);
}

//-->
</script>
		<img name="userimage" src="/images/user/§NCHOST_NICK§.gif" 
onError="change(this); return false;" width="101" height="121" border=0 alt="">
	</div>

Reporter you might use the dom method setAttribute("src",imageRef) as a work
around. The rest is, the same never ending story, traced down to bug 20110. 

Btw, this is an cache error, set both cache settings (memory/disk) both to 0 and
then you will have no problems with the rollovers. When the new necko cache has
landed, I suspect all this is history!

Given how much Pavlov loves getting bugs from me I've decided to give him this
one too :-), he's working on the new image/cache code.

Patches welcome ;-)
