Jump to PostThe user-agent string contains the information you need. Using JavaScript you can access it through the browser's navigator object, e.g.
navigator.userAgent.
Jump to PostLine 16, document.getElementById("demo") is returning null. There is no element with the ID demo.
Insert something like
<p id="demo"></p>at line 11 and you should find it'll work.

<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Inform about user browser and Os</title>
<body>
<button id="display" onclick="myFunction()">Detect User browser and Operativ system</button>
<script>
function myFunction()
{
var x = "User-agent header sent: " + navigator.userAgent;
document.getElementById("demo").innerHTML=x;
}
</script>
</body>

You simply need to parse the string. So for example...
Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36
In this string, you can tell that the user is running Windows 8.1 because "Windows NT 6.3" indicates that the OS is Windows 8.1
