38610 - unexpected js component interface error

Status: VERIFIED FIXED

(Core :: DOM: Core & HTML, defect, P3)

Description

[sean echevarria]

Loading the attached html file generates a js error: Exception... "Component 
does not have requested interface" code: "-2147467262" nsresult: "0x80004002 
(NS_NOINTERFACE)"

It appears that mozilla considers 'complete' an interface of an image object?

d'oh - actual js code:

<script LANGUAGE=JavaScript>
diceFrame = new Array ();
totalFrames = 6;
allMediaLoaded = true;

for (var frameNo = 1; frameNo <= totalFrames; frameNo++) {
    diceFrame [frameNo] = new Image (90,90);
    diceFrame [frameNo].src = 'frame' + frameNo + '.gif';
}

for (var frameNo = 1; frameNo <= totalFrames && allMediaLoaded; frameNo++)
    allMediaLoaded = allMediaLoaded && diceFrame [frameNo].complete; // problem

alert(diceFrame [frameNo].complete);
</script>

Actually, it's saying that the interface doesn't have this property. 
I assume it needs to be implemented. --> Dom Level 0 jst/desale

<script LANGUAGE=JavaScript>
  var foo = new Image (90,90);
  foo.src = 'whatever.gif';
  var bar = foo.complete; // problem
  alert(bar);
</script>

This should IMO be fixed for beta2, adding keyword.

This is needed for beta2; giving PDT approval.

Almost works in my tree, still needs some work but it's getting close.

M16 has been out for a while now, these bugs target milestones need to be 
updated.

While I do have an almost functioning fix for the img.complete on images created
in JS problems I don't feel comfortable with checking that in at this point, in
stead I'll fix the incorrect exception now and leave the img.complete problem to
bug 28277...
