Warning for Non-JavaScript Browsers

If you have to do something important using JavaScript, then you can display a warning message to the user using <noscript> tags.

You can add a noscript block immediately after the script block as follows −

<html>
   <body>
      
      <script language="javascript" type="text/javascript">
         
            document.write("Hello World!")
         
      </script>
      
      <noscript>
         Sorry...JavaScript is needed to go ahead.
      </noscript>
      
   </body>
</html>

Now, if the user's browser does not support JavaScript or JavaScript is not enabled, then the message from </noscript> will be displayed on the screen.

Thanks and Regards,
