Why? How can the reply be 'Yes' and 'No' at the same time? Radio looks the
sensible choice here.

Not true, see below.

permission[4] is a valid value for the name attribute of the <input> element,
as described in the HTML specification.

The input element's name attribute is of type CDATA with no further
restrictions defined by the specification.

The last discussion I remember of this ended up with these messages:
(very long URL - your newsreader may wrap it)

http://groups.google.co.uk/groups?hl...r%3D%26hl%3Den

The message linked says [] in an input name is invalid, the replies disprove
this.

Individual languages may have trouble with non-alphabetic characters as part
of a name attribute, but it's valid HTML and so should really be possible to
deal with it in any language working with HTML.

(BTW I'm not sure why this is posted to either of the PHP or JavaScript
newsgroups, since the only posted content is in valid HTML)

I don't think that the discussion that you referenced does prove the
general suggestion that [ and ] are invalid in HTML 4 name attribute
strings is incorrect. If I look at the HTM versions of the DTDs I find
that the Name attributes are described as CDATA and the term CDATA is
linked to:-

<quote cite="http://www.w3.org/TR/html4/types.html#type-cdata">
....
For some HTML 4 attributes with CDATA attribute values, the
specification imposes further constraints on the set of legal values for
the attribute that may not be expressed by the DTD.
....

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be
followed by any number of letters, digits ([0-9]), hyphens ("-"),
underscores ("_"), colons (":"), and periods (".").
....
</quote>

- which is part of the HTML 4 specification and "imposes further
constraints" on the contents of name attribute strings beyond the normal
definition of CDATA.

Valid HTML or not, JavaScript can access properties with names that do
not represent valid identifiers in JavaScript by using square bracket

</quote>

- which is part of the HTML 4 specification and "imposes further

definition of CDATA.

No, the restriction on the NAME and ID types don't apply to the CDATA type.

Quoting the whole lot:

"
* CDATA is a sequence of characters from the document character set and may
include character entities. User agents should interpret attribute values as
follows:
Replace character entities with characters,
Ignore line feeds,
Replace each carriage return or tab with a single space.
User agents may ignore leading and trailing white space in CDATA attribute
values (e.g., " myval " may be interpreted as "myval"). Authors should not
declare attribute values with leading or trailing white space.

For some HTML 4 attributes with CDATA attribute values, the specification
imposes further constraints on the set of legal values for the attribute that
may not be expressed by the DTD.

Although the STYLE and SCRIPT elements use CDATA for their data model, for
these elements, CDATA must be handled differently by user agents. Markup and
entities must be treated as raw text and passed to the application as is. The
first occurrence of the character sequence "</" (end-tag open delimiter) is
treated as terminating the end of the element's content. In valid documents,
this would be the end tag for the element.

* ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by
any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons
(":"), and periods (".").

* IDREF and IDREFS are references to ID tokens defined by other attributes.
IDREF is a single token and IDREFS is a space-separated list of tokens.

* NUMBER tokens must contain at least one digit ([0-9]).
"

So, it's saying that if you look through the specification on some of the
attributes that are of CDATA type, there are then further notes on restrictions
not expressed by it being of type CDATA.

There are no further restrictions listed for input's name attribute that I can
find - if you can see one please post it!

There then follows descriptions of the ID, NAME, IDREF, IDREFS and NUMBER
types; none of which are CDATA, they're separate types.

For example:

http://www.w3.org/TR/html4/struct/li...ml#adef-name-A

The name attribute of the <a> tag is of type CDATA, but it says here that it
is restricted to the namespace of the id attribute, which is of type 'name'.

That's a "further constraint on the set of legal values for the attribute that
may not be expressed by the DTD"

Individual languages may have trouble with non-alphabetic
characters as part of a name attribute, but it's valid HTML
and so should really be possible to deal with it in any
language working with HTML.

Looking at it again I think you are right. Looking at the HTML source of
types.html made it clear that CDATA (and notes related to it) is/are
separate from NAME and ID (separate LI elements) and the additional
restrictions on NAME and ID do not apply. Interesting to see semantic
mark-up actually providing additional clarity.

You lost me with most of this, but I thought I'd show you the little
problem I had today

This doesn't work

<SCRIPT LANGUAGE="JavaScript" type="text/javascript">
function checkOne(j) {
box = eval("document.form1." + j);
if (box.checked == false) box.checked = true;
}
</SCRIPT>

<td><select name=\"select".$i."\" onChange=\"checkOne(".$i.")\">

(where $i is a number)

But this does:

<SCRIPT LANGUAGE="JavaScript" type="text/javascript">
function checkOne(j) {
box = eval("document.form1.C" + j);
if (box.checked == false) box.checked = true;
}
</SCRIPT>

where I preface the checkbox name with a C

You seem to be correct.

Checking the DTD of HTML 4.01, only the id attribute is ID, and only
two attributes of the meta tag and the type %Lanuagecode are NAME.

The only thing that bothers me a bit is this:
<URL:http://www.w3.org/TR/html4/struct/global.html#adef-id>
where the id attribute is declared as a (lowercase) "name", which linkes
to <URL:http://www.w3.org/TR/html4/types.html#type-name> (the paragraph on
ID and NAME tokens). According to the DTD, the id should be an ID.
Hmm, I also stubmled over this paragraph:

--- <URL:http://www.w3.org/TR/html4/struct/links.html#anchors-with-id> ---
The id and name attributes share the same name space. This means that
they cannot both define an anchor with the same name in the same
document. It is permissible to use both attributes to specify an
element's unique identifier for the following elements: A, APPLET,
FORM, FRAME, IFRAME, IMG, and MAP. When both attributes are used on a
single element, their values must be identical.
---

I can't read with absolute certainty whether this restriction is only
on the mentioned elements, and id and name can be distinct on other
elements, but I believe it is only for those mentioned. These elements
are the ones that are represented in Javascript in global collections,
(document.{links,anchors,applets,forms,images}, and window.frames),
so they should be globally unique. Comments?
http://www.w3.org/TR/html4/struct/li...ml#adef-name-A

The name attribute of the <a> tag is of type CDATA, but it says here that it
is restricted to the namespace of the id attribute, which is of type 'name'.

I don't read it as saying the CDATA is *restricted* to the name space
of the id attribute. It says
"Note that this attribute shares the same name space as the id attribute."
Sharing a name space just means that an id attribute and a name attribute
with the same value will conflict, and it isn't allowed.

I can't see anything that prevents the name attribute from containing
characters not possible in an id attribute In fact, in the same
section as the above quote, they explicitly mentions "D&uuml;rst" as a
legal name attribute value for an anchor.
Thanks for pointing this out. I always like to get smarter :)

Honestly John, that problem drove me up the wall - I was just happy to

scrapped it for something I found on the 'net to get it working. I
