Why not just using ajax for Page Requests to load the page content?

Question

Many web pages load all of their content to change very little information.

Now I would like to know why shouldn\'t the developers just use ajax for the main page re

Answer 1

Well, you can always add the onclick event unobtrusively using jquery and stop the normal URL handling.

Eg:

HTML

Click me to do AJAXy stuff if you have javascript

then Javascript

$(document).ready(function() {       
  $("#ajaxify-this").click( function(e) {
       updateContent(); // do something ajaxy with the page
       return false; // stop the click from causing navigation
   })
}
