Is there any way, via C# code, to detect whether JavaScript is enabled or disabled? If I’m using JQuery for developing a website, if JavaScript is not enabled, then what do I do? How should I handle it?

    C# has no way of determining this. C# runs on the server and sends output to the client. It has no idea if the client is capable/willing to run JavaScript.

    Also, a script can never truly know this either, since it’s not executed anyway.

    The only way you can “react” to disabled JavaScript would be to use a <noscript> tag to advise your users that JavaScript is required for your site.

    You can see an example of this on StackOverflow. Turn off JavaScript, refresh the site, and you will see:

    <noscript> 
    <div id="noscript-warning">Stack Overflow works best with JavaScript enabled<img src="http://pixel.quantserve.com/pixel/p-c1rF4kxgLUzNc.gif" alt="" class="dno"></div> 
</noscript>
