Clientside browser sniffing via Microsoft Ajax Libraries

switch(Sys.Browser.agent) {
case Sys.Browser.InternetExplorer:
alert(“IE”);
break;
case Sys.Browser.Safari:
alert(“Safari”);
break;
case Sys.Browser.Opera:
alert(“Opera”);
break;
case Sys.Browser.Firefox:
alert(“FF”);
break;
default:
alert(“default Browser”);
}

Easy? Do I need to say anymore?
