For even more information you can try this:

var N= navigator, str= '';
for(var p in N){
    if(typeof N[p]=='string') str+= '\n\n'+p+'= '+N[p];
}
 
alert(str);

Welcome to TSDN.
One thing let me clear why you suddenly trying to do System Program with JavaScript?
Anyway, I think it is not possible to get the OS related Informations using Standard JavaScript.
And the JavaScript is not for that.And what others suggested this will not help you.
Look, navigator object only holds the Informations related to Browser you are using.
But OS related Informations Quite Absurd.

Kind regards,

hi ...

give:

navigator.userAgent

a try ... it returns something like the following:

"Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3"

so you may retrieve the OS-info from it with a regEx or indexof or whatever you prefer ...

kind regards

Not quite so absurd. Take a look at this example.
