HTMLJavascriptProgramming Scripts

To get information about the browser your webpage is currently running in, use the built-in navigator object. You can use various Navigator methods and properties with the object.

Example

You can try to run the following code to implement Navigator object in JavaScript −

<html>
   <head>
      <title>Navigator Object Example</title>
   </head>

   <body>
      <script>
         <!--
            var userAgent = navigator.userAgent;
            var opera = (userAgent.indexOf('Opera') != -1);
            var ie = (userAgent.indexOf('MSIE') != -1);
            var gecko = (userAgent.indexOf('Gecko') != -1);
            var netscape = (userAgent.indexOf('Mozilla') != -1);
            var version = navigator.appVersion;
           
            if (opera) {
               document.write("Opera based browser");
               // Keep your opera specific URL here.
            }
            else if (gecko) {
               document.write("Mozilla based browser");
               // Keep your gecko specific URL here.
            }
            else if (ie) {
               document.write("IE based browser");
               // Keep your IE specific URL here.
            }
            else if (netscape) {
               document.write("Netscape based browser");
               // Keep your Netscape specific URL here.
            } else {
               document.write("Unknown browser");
            }
            // You can include version to along with any above condition.
            document.write("<br /> Browser version info : " + version );
         //-->
      </script>
   </body>
</html>
