JQuery Ajax help please

JQuery Ajax help please

 I am very new to JQuery and Ajax and have a problem.  Hope people can help.

I am using the ui draggable plugin for drag & drop into a drop zone and then update a database table like this: 

function addlist(param)
{
    $.ajax({
    type: "POST",
    url: "ajax/addtocart.php",
    data: 'img='+encodeURIComponent(param),
    dataType: 'json',
    beforeSend: function(x){$('#ajax-loader').css('visibility','visible');},

   
   
    });
}











The update into the sqltable works with the above, but after the update I want to update a PHP MySql query running on another page that displays the ALL the details in the table that is being updated without reloading the other page. How? what do I use in the

    success: function(response) { } to do that?

I don't want to just dispaly the updated row but all the data in the table.
