How To Detect Chromium Os Using Javascript?

I use Windows to develop my app and I use navigator.platform to detect the OS type. I don't have a Chromium OS so I don't know what the value will be returned by the above script.

Solution 1:

In the userAgent you will get Chrome and then CrOS

For example: var ua = window.navigator.userAgent; // Then check if the UA is something like: Mozilla/5.0 (X11; CrOS i686 0.12.433) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.77 Safari/534.30

Here is a post I've wrote about it in the past: http://greenido.wordpress.com/2011/06/14/how-to-detect-it-is-a-chromebook/
