Yes,

The navigator.userAgent usually returns that info togther with others.
eg. Mozilla/2.0 (Win16; I)

Try this:

getOS() {
startvar = "(";
endvar = ";";
browser = navigator.userAgent;

for(i=0;i<browser.length;i++)
  {
  if(browser.charAt(i) == startvar)
    {
browser.substring(i-1, browser.length).indexOf(endvar) + i-1;
OS = browser.substring(i+1,end);
    }
 }
return OS;
}

That should work.

Oops. This line:
browser.substring(i-1, browser.length).indexOf(endvar) + i-1;

Should have read:

end = browser.substring(i-1, browser.length).indexOf(endvar) + i-1;
