How to detect operating system on the client machine?


How to detect operating system on the client machine?

To detect the operating system on the client machine, your script can analyze the value of navigator.appVersion or navigator.userAgent. Below is a simple example of a script that sets the variable OSName to reflect the actual client OS.

// This script sets OSName variable as follows:
// “Windows”    for all versions of Windows
// “MacOS”      for all versions of Macintosh OS
// “Linux”      for all versions of Linux
// “UNIX”       for all other UNIX flavors

var OSName=”Unknown OS”;
if (navigator.appVersion.indexOf(“Win“)!=-1) OSName=”Windows“;
if (navigator.appVersion.indexOf(“Mac“)!=-1) OSName=”MacOS“;
if (navigator.appVersion.indexOf(“X11“)!=-1) OSName=”UNIX“;
if (navigator.appVersion.indexOf(“Linux“)!=-1) OSName=”Linux“;

document.write(‘Your OS: ‘+OSName);
