Operating System
Question: How do I detect the operating system on the client machine?
Answer:
To detect the operating system on the client machine,
your script should analyze the navigator.appVersion string.
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
// "Unknown OS" indicates failure to detect the OS
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);
On your system, this script yields the following result:
(To get more detailed OS information, your script should perform
a more sophisticated analysis of the navigator.appVersion string,
but the idea would be the same.)
