Environmental Variables Available in Javascript using Navigator Object

Most environmental variables available in Perl and PHP are not accessible in Javascript.

But there are still some very useful bits that might help you in your programming needs.

You can access them via the navigator object like so:

document.write(navigator.appName);

Which prints:
Netscape

... on my machine since I use Firefox on Mac.


Or store their value in your own variable like this:


var ji = navigator.appName;

document.write(ji);

Which prints:
Microsoft Internet Explorer

... on my test machine over my shoulder that runs Windows XP.


NOTES:
- As always, the availability of the following environmental variables will depend on the user's Operating System and browser type. Example: cpuClass returns undefined if the user is on Firefox for Mac.
