"Browser Detection" Version 1

<SCRIPT>

var bName = navigator.appName;
var bVer = parseInt(navigator.appVersion);
var IE = "Microsoft Internet Explorer";
var br;

// "n3" is short for Netscape 3.x or greater or JavaScript 1.1 or greater
if ((bName == "Netscape" && bVer >= 3) ||  (bName == IE && bVer >= 4)) br = "n3";
else br = "n2";

bName (browser Name) & bVer (browser Version) gives us enough information to decide what the browsers are capable of based on the information we just gathered.

if (br == "n3") { // this should look a lot like document.images for example
     var displayOn = new Image();
     displayOn.src = "images/displayOn.gif";
}

document.write("Browser Name is " + bName + "<BR>");
document.write("Browser Version is " + navigator.appVersion + "<P>");

document.write("var bName is " + bName + "<BR>");
document.write("var bVer is " + bVer + "<P>");
