How do we determine if Javascript is enabled?
Use Javascript.

function javascriptEnabled(){
	 return true;
}

Great if it returns true...and if not:

function validateSettings(){

  if(!javascriptEnabled()){
	location.href="no_js.htm";
  }

Hope groovicus doesn't fall out of his chair. And yes...this code is on a production server, up and running.

Romeo29 is right. You could always use the <noscript></noscript> tags to display a message, though.

If javascript is not enabled then how would this code execute?

Okay, I need to start reading the topics more carefully. I actually thought you were asking why it wasn't working, raw!!

Forgive me, for I know not what I type.

One workaround is using JavaScript + PHP and make JS function return to a PHP function. Is this possible? I faintly remember reading this in a book. But I am wrong all time

I didn't claim it as my code or my server. Just sharing it.

It doesn't work. Test it yourself. Thanks for screwing with my brain for awhile though.

Personally the script that raw showed us, I would not have used at all...

That was the point. An example of poor coding.
Found this, might be useful.
