It is well-documented that if on a page there are several radio-
buttons with the same name these are addressed as an array (and act
collectively).
Someone (LRN?) recently wrote about another case where name-match
implies array addressing.
It therefore occurred to me to try the following crude Web page :
<head></head><body>
<form name=F1>
<input type=text name=A size=3 value=00>
<input type=text name=A size=3 value=11>
<input type=text name=A size=3 value=22>
<input type=button name=B onClick=X() value=" ?? ">
</form>
<script>
J=0
function X() {
F1.B.value = " " + F1.A[J++%3].value + " "
}
</script>
</body>
On it, in my MSIE4, pressing the ?? button repeatedly cycles its
legend through 00 11 22 00 11 22 00 ... which demonstrates that such
a set of name-matched controls can be accessed as an array there.
Is that legitimate and generally available? I do not recall reading
it.
In particular, where I have a table similar in principle to
2001 2002 2003 2004 2005
St P Sat Sun Mon Wed Thu
St G Mon Tue Wed Fri Sat
St A Fri Sat Sun Tue Wed
and wish to auto-change the columns to be Year-2..Year+2 for any
(current) Year, can I use for the St P row five instances of
<input type=text name=StP size=5 readonly> and compute in turn
elements [0]..[4] of this array (likewise for other rows), and have
it working successfully for all reasonable javascript-enabled
browsers?
Could I use <div>..</div> with DynWrite thus, instead of <input
....>?
I postpone the possibility of having a dynamic column-count such
that there is at least one instance of each of the days of the week
in both the row for Feb 28 and that for Mar 1.

Omission of the quotes around the onclick attribute value may have
been intentional, but I would like to point out that the only non-
alphanumeric characters that may appear in an unquoted attribute
value are hyphens, periods, underscores and colons.

Netscape's JavaScript reference (v1.3) states in the introduction for
the Radio object that a group of radio buttons under the same name
may be indexed with subscripts. In addition, the DOM method,
getElementsByName, will return "the (possibly empty) collection of
elements whose name value is given" in the argument to the method.

Only INPUTs of type radio and checkbox can share control names. A
solution would be to use an array that contained the names of each
text box, index that, and use the value with the elements property of
a Form object or, if they are id values, as the argument to the
getElementById method.
Could I use <div>..</div> with DynWrite thus, instead of <input

If you are referring to dynamically altering an already loaded page,

Probably. It works that way for all form controls. Try:
<form id="foo">
<input type="text" name="x" value="42">
<input type="radio" name="x" value="37">
<input type="checkbox" name="x" value="87">
<select name="x"><option value="13" selected="selected">X</option></select>
</form>
<script type="text/javascript">
var xs = document.forms['foo'].elements['x'];
alert([xs.length,xs[0].value,xs[1].value,xs[2].value,xs[3].value]);
</script>
It alerts
4,42,47,87,13
in IE6, Opera 7, and Mozilla (and with some rewriting also in Netsape 4).
J=0
function X() {
F1.B.value = " " + F1.A[J++%3].value + " "
}

It's not an array. If you check with "... instanseof Array", it gives
false. In Opera, it's an Object. In Mozilla, it's a NodeList. The
important thing is that it doesn't have a dynamic length or the methods
of Array.prototype.
Is that legitimate and generally available?
Apart from writing
F.B.value
instead of
document.forms.F.elements.B.value
then yes. (It wouldn't work in Mozilla using F as a global variable)
I do not recall reading it.
I can't find it in the DOM specification.
The HTMLFormDocument's "elements" property is a HTMLCollection.
Its "namedItem" method is only allowed to return a single Node.
It is probably a result of the DOM specification being written
to be compatible with typed languages, so the "namedItem" method
can't return a Node in some cases and a NodeList in others (NodeList
is what is returned by, e.g., getElementsByTagName)
So, you'll have to look at the browser specific DOMs to find anything.
in Microsoft's documentation, you find:
---
If this parameter is a string and there is more than one element
with the name or id property equal to the string, the method returns
a collection of matching elements.
---
There is problably something similar in a Netscape documentation.
In particular, where I have a table similar in principle to
2001 2002 2003 2004 2005
St P Sat Sun Mon Wed Thu
St G Mon Tue Wed Fri Sat

It should work. But if you have a table with a known width/height, you
can just name the elements based on the coordinates, e.g.
name="St(2,3)"
Could I use <div>..</div> with DynWrite thus, instead of <input
...>?
Not generally, no. There is no "name" attribute on a div, and the
"id" attribute must be unique. In IE, you can have several elements
with the same id, and document.all/document.getElementById will
return a collection. That is not portable.

That's how I read it. There is no explicit requirement in HTML that

have a problem with several controls with the same name. The resulting
URL is "...?x=XXX&x=YYY&x=ZZZ".

In my previous response, I didn't think properly about the above
statements. You are correct - there is no restriction stating that
control names must be unique within a form. In fact, it appears that
with form submission, data would be sent like so:
<FORM action="..." method="get">
<INPUT name="address" value="My house number">
<INPUT name="address" value="My street">
<INPUT name="address" value="My city">
</FORM>
....?address=My+house+number&address=My+street&add ress=My+city
That is, all data, in the order it appears in the document.
I have a question though. I know very little of the DOM, so I was
wondering if someone could tell me how you would know what form
elements came from which form if you retrieved them using
HTMLDocument.getElementsByName(). After obtaining the collection
returned, would you use Node.parentNode to get a HTMLFormElement
object, then HTMLFormElement.name to get the name? So, for the first
matching name (we'll assume it will be in a form), would it be
something like this?
function getFormContaining( elementName ) {
var matches = document.getElementsByName( elementName );
return matches[ 0 ].parentNode.name;
}
Mike
I will learn about the DOM someday...

No. The form doesn't need to be the immediate parent node of the

You should be able to. That is defined in the specification:
For application/x-www-form-urlencoded (which includes anything
submitted with the GET method), "The control names/values are listed
in the order they appear in the document."
For multipart/form-data, "The parts are sent to the processing agent
in the same order the corresponding controls appear in the document
stream."
I don't know if scripting languages have that order imposed, though
(I haven't looked, nor do I quite know where to look).

Again, it is no array. But yes, you can. The collections, although
first standardized in W3C-DOM Level 1, is part of the so-called DOM
Level 0, which originates from the 3.0 versions of Netscape and
Internet Explorer.

That would be a misuse of the DIV element which should mark a division
of a document (containing text, supposedly paragraphs). You have a
table-like layout and should therefore use table elements, primarily
`table', `tr' and `td'.

The DOM specification doesn't say so. It makes no provision for more

http://www.w3.org/TR/DOM-Level-2-HTM...ml#ID-75708506
Actually, the result is not a collection.
In Opera 7, it is an ElementsArray, in Mozilla its a NodeList (the
same type as is returned by getElementsByTagName). They implement the
interface of an HTMLCollection, though (the method "namedItem", which
isn't part of a NodeList, and seems to be the only difference between
a NodeList and an HTMLCollection).
In Mozilla,
document.forms.foo.elements.x instanceof HTMLCollection
gives false, while
document.forms.foo.elements.x instanceof NodeList
gives true.
In IE I don't know what it is, it might be a collection. But it is a
very awkward object, because if you iterate through its properties
with for(...in...), the name occourse once for each control with that
name. That is, the same property name occours more than once during
the iteration.

To check whether I understand : while that looks like a quoted C array
(?) or a function call, it is actually a mere string of three parts -
Alpha since names should start that way, an up/down part, and a left-
right part.
Correct. Since names can contain anything, I decided to use a standard
coordiante notation. In practice, "St_2_3" would probably be better,
and it contains the same information.
In addressing, the names would be computed, rather than indexing a
single name.
Precisely.
If I use separators, they will be ones commonly used in names, probably
underscores; or even as x12y25 (I can assume 2 digits always suffice.
Good choice :)
But I could, I think, DynWrite[1] the whole Table into a <div> after the
page is loaded ... which is not needed, so I can document.write it
during page loading ... which, by parameterising the data, may well
reduce the page size.
Yes. If the page critically depends on Javascript anyway, creating the
content with Javascript isn't a problem. If the page can be used
without Javascript, then making it dependent is inferior.
The appearance that way would be a lot better than what using
controls would give; would, in fact, be unchanged.
Yes, there would be no difference between that table and any other
table, except what you choose.

That is indistinguishable.
Disagreed.
My words do not imply having all the properties of an array.
AIUI, when you access something as an array, it is an Array object,
meaning its constructor function is Array(...). In contrast, when
you access something *like* an array, you access something on which
you can (also) use the index operator to access an element of it.

It is not but only because of F1.B which should read
document.forms["F1"].elements["B"].
Valid, but not relevant to the question.
It is of course relevant to the question. You asked for general
availability. Nowhere is specified that you can access
document.forms["F1"].elements["B"] with document.F1.B as well.

The only helpful unsolicited observation; but not a well-considered one.
You have not stated whether <div> *could* be used,
If I write that it is a misuse it is obvious that it *can* be used but
*should* *not*.
nor have you stated whether DynWrite should generally work into a

It is not.
To contribute to a newsgroup without bothering to read the regularly-
posted FAQ is either stupid or arrogant or unhelpful (or != xor).
With your self-acknowledged vast knowledge of the language, you should
have known that it is not a function specified by ECMA, Microsoft, etc.;
and you should have realised that I would not have referred to it in
that manner if I had not thought that regulars here should know about
it.
You may, of course, feel that you know so much that no FAQ can possibly
teach you anything.
But a knowledge of the contents of the FAQ would enable you to see that
some questions are best answered by citing it, rather than by repeating
well-known material. Citing the FAQ may pre-empt other questions.
And it is always possible that you might be able to suggest improvements
to the FAQ.
As regards DynWrite : it may be less worthwhile if only the latest
browsers are to be supported; nevertheless, if a script can use it
several times, IMHO using a version of DynWrite is still worthwhile
since it expresses the action, the source, and the destination without
encumbering the statement with mechanism.
Insufficient use of subroutines is one of the three commonest faults one
sees in code posted here, possibly omitting faults-of-detail.

More or less done, AFAICS, except that there is not yet provision for
supplying the Danish words for "Annual Holidays", "Holiday", "Month,
"Day", which should be easy enough.
There's currently no Include file; the code for a big Object defining
the holidays and selecting their rules needs to be pasted into a

America are built in, however.
