[Javascript] Browser sniffing!

[Information - Abyss]

Good Evening,

I am wanting to write a Javacript file that will find a browsers name and browser version

so that anything less then IE 7 it displays an error message I tried the follwoing

window.onload = fncOnLoad;

function fncOnLoad()
{
 alert("APP NAME:" + navigator.appName);
 alert("appVersion: " + navigator.appVersion);
 alert("Product: " + navigator.product);
 alert(" vendor:" + navigator.vendor );
  alert(" app code name:" + navigator.appCodeName  );



}


but that did not return what i wanted....

eg it would return Mozilla (rather then FireFox) and it would return version 4 for IE6..

would someone please be able to shed some light on this?

Thank you for your help
Abyss.
