Hello all,

I'm developing a site that will use technologies like JavaScript and AJAX. I want the site to be functional for people that has older browsers or JavaScript turned off so for this I need to find out if the user's browser is supporting JavaScript and AJAX.

How can I check this in an easy and simple way? I.e the user enters my website with JavaScript turned off at the moment. And then he turns it on and reloads the page. I would like to catch that he has turned JavaScript on. The same goes with AJAX (although there is no off/on setting for AJAX).
