It's often necessary to make a script only accessible to the newer
browsers (that can support the script without error) and keep older
browsers from trying to work with it. This script, as an added plus, is
very short
<!-- TWO STEPS TO INSTALL NEW BROWSERS ONLY:
1. Paste the coding into the HEAD of your HTML document
2. Add the last code into the BODY of your HTML document -->
<!-- STEP ONE: Copy this code into the HEAD of your HTML document -->
<HEAD>
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function onlyNewbrowsers() {
browser = (((navigator.appName == "Netscape") &&
(parseInt(navigator.appVersion) >= 3 )) ||
((navigator.appName == "Microsoft Internet Explorer") &&
(parseInt(navigator.appVersion) >= 4 )))
if (browser) {
alert('You are obviously using Netscape 3+ or MSIE 4+. Older browsers are not allowed to read this.....')}
else {}
}
// End -->
</SCRIPT>
<!-- STEP TWO: Put this code into the BODY of your HTML document -->
<BODY>
<CENTER>
