Hi there,
after making work some code for Safari, Firefox and Opera it was
time to invite "party pooper" IE to the party.
After a while understanding myself and the Microsoft IE script
debugger this bug IE "reports" was found. All was hasAttribute
related.
With a little use of the console I was able to see that the element
that the code was "talking" to was already extended as expected but IE
still complains.
Found that in IE 6 (I didn't test this other versions yet)
hasAttribute returns correctly true when the given attribute is found
in the element but it returns null in case it don't which is
inconsistent. I don't know if this is a bug or a feature but given
that all other browsers returns false as expected for that case I
propose replace this:
"...
Element.Methods.Simulated = {
hasAttribute: function(element, attribute) {
var t = Element._attributeTranslations, node;
attribute = t.names[attribute] || attribute;
node = $(element).getAttributeNode(attribute);
return node && node.specified;
}
};
..."
with this:
"...
Element.Methods.Simulated = {
hasAttribute: function(element, attribute) {
var t = Element._attributeTranslations, node;
attribute = t.names[attribute] || attribute;
node = $(element).getAttributeNode(attribute);
if(!node){return false}
else{return node && node.specified};
}
};
..."
because with that it seems to behave.
The other issue I've found is related to the extension of elements
with empty id. I found that IE considers obscene to extend a div which
has no id (collected using getElementsByTagName('div')). Other
browsers seems to behave. Is desirable that one can give an
homogeneous treatment to this creatures (elements I mean) so I will
workarround it by now but I think something has to be done to properly
extend elements without id even in IE (for consistence).
I figured out this all is with Prototype 1.5.1_rc1 so maybe it's fixed
I don't know yet
cheers,
Sebastian
