As AJAX and Javascript are used more and more in web sites, we tend to forget that our visitors can disable javascript. This can have unpredictable results. For example, if we are validating forms using Javascript (it is better to use server side!), or if navigation is dependent upon Javascript, you would rather your visitors enable the script.
Fortunately, there is an easy solution.
Place this code in your web page... I place it right before the first script.
<noscript>
<meta http-equiv="refresh" content="1; URL=http://yourwebsite/yourwarningpage.php" />
</noscript>
That's it. So, if Javascript is not enabled, users will be directed to the page you specify with the refresh tag.
