Detect N2/N3/N4/IE2/IE3/IE4 + subversion + Jscript

I need a generic Javascript that give all the OS and Browser info that is available,
nicely cut into small parts.

I don't know exactly how to frase my question more explicitly, but this is a try
(don't hurt me if if respond with: cut that into nice parts too):
I don't know which information is accessible without a CGI script, must give as much of the
following as possible:

 a - Will not give errors with any regular browser (N2/3/4, MSIE2/3/4, Opera: any platform)
 b - Set VAR Browser to "Netscape" or "MSIE" (or to others, "Opera" or whatever exotic
stuff is available)
 c - Set VAR Version to "2" or "3" or "4" or whatever version when appropriate
 d - Set VAR Subversion to ".03" or "0.1.revB" or ".2" or whatever subversion/revision when appropriate
 e - Set VAR JVS to "1.0" or "1.1" or whatever Javascript version when appropriate
 f -  Set OS to the most specific name and SubVersion (OS="WIN" SV="NT" SVadd="5")
g -  To test, display a message, or generate a new HTML page or frame showing everything.

This is tough due to the amount of work involded.
I start with 400 points.

Merci,

That's nearly all info one can get about browsers
and OS. Unfortunatly JavaScript do not have a good way to obtain operating System, but Java have. On case Java isn't ON or non-java browser you can try to parse major OSes from appVersion
as I do in script below for win95, winNT and Mac.

The most sad that only one num after point in most browsers
is available so you can't get NN3.02 you will get only 3.0

With Java disabled, N4 gave 2 errors: Kollegov,
which is in conflict with condition a (Will not give errors with any regular browser)

java is not defined and unterminated string literal.
         document.writeln('java.class.version :
..........................^

They must be avoided.
Otherwise, the script is excellent.
Please modify.

Well, I corrected this problem, sorry, missed it.
Just forgot that MIE do not allow to call java package methods
only applet methods can be called.
So if you still interested to obtain some
additional info about browser though java I can create
special applet for this. MIE allows to call applet methods,
so this is only technical problem. :)

But if you want to limit yourself with javaScript solution
there is complete info you can obtain, nothing more :(

Generally you can get only browser, version (including OS sometimes) and try to parse OS out of this info if it's included.
There is no difficalties with JSV as you can see.

Main difficalties are with OS. there are too many OSes to
detect all and there are too many differences between all existing browsers to do this correctly.
The only direct way to get OS name through java, but not all browsers are supporting Java and interaction between Java and JavaScript. as I know (MIE4+ and NN3+ only)

I do not want to waste my time for this 'special' applet if
you do not want this way, but if you need I can do it..


In edition below, only Netscape will give additional info
I disabled this for other non-live-connect browsers

Hey, I just cut and past it from my page...and I am giving you permission to use it
If you don't believe me, then email me at the email address in my code; and I will email you back.
The only thing that I ask is, if you decide to use my code...and anyone (or yourself) makes a fix to it:
then email me with the new source code.

Luiaard, you don't answered my question about way to obtain
OS name through Java applet. Do you need it?

Hi, CyberMage, do you think you give better approach than
my last comment? Your 'answer' do not give more info
than particular

appName
appVersion
appCodeName

It do not detect JavaScript version

do not split the Version number to Major version, subversion
and OS,  it just gives some more info about  plugins
and mime types, which wasn't requested.

Kollegov: I do not care about the means, I just care about the result.
If the call to Java makes the result better, then I need it.
If it causes any errors in some cases, and in other cases gives a better
result, then I do not need it.

Cybermage: Thank you for committing your result. I'm a bit food-poisened
right now, so it will take me some days to evaluate your answer (or get to
out of bed :-((    .

With regards,

To everyone: I will evaluate the results as soon as I can.
Please hold on, and get on submitted.

Luiaard, in such cases I usually suggest to share points
(from my own ones, which I do not know how to use) with
other expert, but I do this when I see that other answer
have something really valuable. In this case CyberMage
do not add anything new even to my first rejected answer.
But if you beleive that CyberMage also need to be granted with points for his work, tell me what value I should post as a 'special' question for him in order to share.
