Which Netscape? (testing.... both Netscape 4 and Mozilla ... and Opera.

Is what normal? That browsers differ? That IE is doing it wrong? No to
both :)

The updated function is getFullYear. It is not available in all old
browsers (although it does seem to exist in both Netscape 4 and IE 4).

No. If you need to add content to a page after it has loaded, you must
use either W3C DOM methods or the Microsoft DOM "innerHTML" property.
Or put the content inside an input element.

As for issue 2. This can be done using the DOM: Document Object Model.
In essence you create a sort of placeholder in the page that can be
written to after the fact. There is a good example of how to do this
sort of thing in the most current edition of Flanagan's "Rhino" book
(Javascript: The Definitive Guide). This book is a must-have, and you
can get it immediately by signing up for a free 2-week trial

Re: 2 Questions (Date and Write)

I have read the following message from "Dennis M. Marks"
<denmarks@domai n.invalid>
and have decided to lend my vast knowledge.

The writer said:[color=blue]

and my reply is:
I found the answer to question 1 (getFullYear). I still need an answer
to question 2.

Client-side speaking, that's also a redraw of the page. You cannot
objectify a bunch of HTML tags and do a object.refresh( ) like VB or C++.

Actually, they are both getting it wrong. getYear *should* return the 2
digit year, of which neither is doing that properly.

Technically, its done with Javascript. Javascript and the DOM are two
different things.

If you follow the recommendation of ECMA262, getYear (which is not a
required property of ECMAScript Date objects) should return the
year - 1900:
---
B.2.4 Date.prototype. getYear ( )
NOTE The getFullYear method is preferred for nearly all purposes,
because it avoids the "year 2000 problem."
When the getYear method is called with no arguments the following
steps are taken:
1. Let t be this time value.
2. If t is NaN, return NaN.
3. Return YearFromTime(Lo calTime(t)) -1900.
---

It is from Appendix B of the ECMAScript standard, which includes
non-normative suggestions for a uniform semantics of common
non-standardized features. These are "escape", "unescape",
"String.prototy pe.substr", "Date.prototype .getYear",
"Date.prototype .setYear", and "Date.prototype .toGMTString".

Really? Wow! But Javascript is just a simpler form of Java, right?

TIA!!

No. Java and Javascript are two completely independent languages with
no more in common that "cat" and "caterpilla r". They look
superficially alike because they both use C-like syntax, but below the
hood they are from differet worlds.

I was being sarcastic.

Don't you remember me? I was contributing on this board late last
summer. In fact, I've since gotten to use some properly functioning
auto-tab code me, and others on this group (sincere thanks), worked out;
I've actually deployed it in a *production* setting.

But I see we've incorporated a new set of wannabes -- er, I mean
"theorists" -- in the meantime.

Actually, you did. The answer is no. The solution to what you want to do
is outlined in http://www.jibbering.com/faq/#FAQ4_15 (that URL was
given, if by noone else, by me.)

OK, you got me, I am a wannabe/theorist. So, putting aside my personal
belief that ECMA is utterly useless since its just a theory about how
things should be instead of how things are, could you please explain how
the DOM is part of Javascript? And please tell which DOM you are
referring to, whether Level 0, Level 1, or Level 2.

I patiently await your "profession al" answer.
