Not working in Modzilla

[News]

Please tell me why this will not work in Modzilla yet works in IE? None of
the <div> show. They are to be layered one on the other and then one show at
a time. Nothing shows and I don't know why.

So that really works in IE?

You're using "getElementById", yet their's no element with that ID.

The "name" attribute is not the same as "ID"

Yup it works on IE, but then that does not mean much

question;

if I dynamically create a couple of <form> elements and in each I
dynamically create a number of <div> elements using JavaScript, will I be
able to capture them using "getElementsByName"?

It does not seem to be working

IE uses "name" as "ID" if there is no ID present, for some stupid reason.

See what was written above - your answer is there.

getElementsByName does not return an object, it returns an array of all
objects with that name. "name" can be duplicated, "ID" should be unique.

document.getElementById in IE is just a "spoof wrapper" over the native
document.all
So it does a lot of strange things on IE. Say it returns *all elements
with matching id OR name*. So say if you have a form with
name="shipping" and a div with id="shipping" you'll get a collection of
two elements (both form and div). And atop of it you'll get
automatically created global variable "shipping" pointing to the div. A
mad house...

On the other end Firefox does a strange thing too: it recognize "name"
attribute for any element and adds it to the DOM tree; but this
attribute is visible as object property only for DOM 0 elements (forms,
form elements, links etc.)

Any way: do not use "name" unless these are DOM 0 elements you can
handle with separate DOM 0 methods (document.forms[i].elements[j],
document.images, document.links, document.anchors). For DOM 1 or higher
methods use ID's and make sure they are unique on the given page.

The - document.getElementById - method in IE does _not_ever_ return a
collection. It returns either a reference to a single Element node or
null.

I suppose that is an inarticulate way of expressing that Mozilla
represents all HTML attributes as attribute nodes in the DOM but does
not create properties of the corresponding Element in the DOM unless
(and with the exception of intrinsic event attributes) the W3C DOM
specification defines the property in the interface definition for the
Element of that type. That is a long way from being strange behaviour.

page.

As all DOM 0 'elements' are formalised in HTML DOM levels 1 and 2 that
advice is impossible to follow. A more reasonable suggestion would be to
only use name attributes on Elements for which the pertinent HTML
version/DTD specifies a name attribute (with additional regard to the
text of the HTML specification).

Right, that must be not my week :-(
I was thinking about getElementByName weirdness in IE.

Here is a summary of the most weird things (by my scale) IE does:

<html>
<head>
<title>IE in all its beauty</title>
<meta http-equiv="Content-Type"
content="text/html; charset=iso-8859-1">
<script type="text/javascript">
function init(){
// 1) IE doesn't distinct names and id's in getElementById
// whatever it sees first - this it returns:
var obj = document.getElementById('shipping');
alert(obj.tagName); // "FORM"

// 2) IE creates parasite global vars for each id'ed element:
try {shipping = 'UPS';}
catch(e) {alert(e.message);} // error

// 3) getElementsByName returns all elements with matching
// name OR id
var elm = document.getElementsByName('shipping');
alert(elm.length); // 2
}

window.onload = init;
</script>
</head>

<body>
<form name="shipping" action="">
<input type="hidden" name="cost" value="10">
</form>

<div id="shipping">&nbsp;</div>

</body>
</html>

I could not care less what you where thinking (if you actually were), it
is the bullshit you posted that I was commenting upon.
