I'm trying to write a simple script that will display the current browser name, version, and the operating system. Here's but don't think I'm on the right path. Also how can I use parseInt() function to print just the version number?

<!DOCTYPE html>
<html>
<head>
 <title>Window Open Example 2</title>
</head>
<body>
 <script type="text/javascript">
 document.write(navigator.appVersion);
 </script>
</body>
</html>

    Standards do not support browser sniffing instead they support determining if the browser has a feature. What this means is that whatever you do today to determine the browser may not work for the next version of browser. Commented Aug 20, 2014 at 8:01

You should use parseFloat in case of Version number like "5.01"

document.write(parseFloat(navigator.appVersion).toFixed(1));

toFixed() tells how many dezimal places should be visible.

-1 navigator.appName does not return the correct browser name since all browsers except IE will probably return Netscape instead. userAgent returns versions for every part of the browser.
yes.but reason for that click here
I know why browsers are returning "Netscape". What basically I'm saying is that your answer is wrong.
