Browser Detection

Almost everything in this tutorial works on all JavaScript-enabled browsers. However, there are some things that
just don't work on certain browsers - especially on older browsers.

Sometimes it can be useful to detect the visitor's browser, and then serve the appropriate information.

The Navigator object contains information about the visitor's browser name, version, and more.

Note: There is no public standard that applies to the navigator object, but all major browsers support it.

The Navigator Object

The Navigator object contains all information about the visitor's browser:

Example /* <div id="example"></div> <script type="text/javascript"> txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>"; txt+= "<p>Browser Name: " + navigator.appName + "</p>"; txt+= "<p>Browser Version: " + navigator.appVersion + "</p>"; txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>"; txt+= "<p>Platform: " + navigator.platform + "</p>"; txt+= "<p>User-agent header: " + navigator.userAgent + "</p>"; document.getElementById("example").innerHTML=txt; </script>

*/

The output will be
