add a method to object HTMLCollection

[Grzegorz ¦lusarek]

Hi all. Is it posible to add a method to prototype of object HTMLCollection?
I mean something like this:
HTMLCollection.prototype.indexOf=function(obj){
var result=-1;
for (var i=0;i<this.length;i++){
if (this==obj){
result=i;
break;
}
}
return result;
}

my trials fail for now but I will try more
thanks for any help

Yes, it is, in the Gecko DOM. However, this does not have an effect on
DOM collections like document.forms or those retrieved with
document.getElementsByTagName() etc. yet: the respective objects do not
inherit from HTMLCollection. It does work for HTMLOptionsCollection,
though.

"Does not work" is a useless error description. [psf 4.11]
