javascript and php web design
<p>I have a question about the way I should build my website. What if the user has javascript disabled, then all the client side programming will be disable. </p>

<p>Should I rely on php at first, and then just add the javascript/jquery/ajax just in case.</p>

<p>Also how could I make partial requests, so that one part of the page is posted back while the other part of the page doesnt refresh (for example, navigating through a list of products on the page through a pager , without the whole page refreshing, like a gridview). How to achieve that?</p>

<p>Sorry, if i was confusing</p>
