4. Requirements
1.AJAX calls (Hail Google !)

5. Code Snippets
<input type="text" class='search_input' /><br/>
Define an “onkeyup” event sen an ajax GET request to 'ajax.php'
containing the parameters: the 'ajaxeeequest' and 'query'
$(".search_input").keyup(function()
{
var search_input = $(this).val();
var keyword= encodeURIComponent(search_input);
$.ajax({
type: "GET",
url: "ajax.php",
data:{'op':'ajaxrequest','query':keyword},
success: function(msg){
$('.inner').html(msg); //fetch the Slide and echo it on the page
}
});
});
