How to detect Android in JavaScript?

JavaScript: How can we detect browser name and version using JavaScript?

• Answer:

  As others have noted, you can pretty easily check the navigator object. For mapping user agent strings to explicit browsers, I usually rely on http://www.useragentstring.com and/or the sample user agent strings in my web inspector. Keep in mind that some users (namely on Android) use mobile browsers that provide a false user agent in order to force a page into rendering as a desktop site. That said, I definitely agree with 's answer - oftentimes it's much better to use a tool like http://modernizr.com to detect what features you need. For instance, even if the userAgent string matches a browser you've tested, there's no guarantee that the browser is up-to-date, nor that future versions of the browser still support the feature you're relying on.
