Question

I want to use $.post function of jquery to do a div refresh, only if the content returned in the json data from the php script is modified. I know that ajax calls with $.post are never cached. Please help me with $.post, or $.ajax if it is not possible with $.postor any other method with which this is possible.

Thanks

Why don’t you cache the response of the call?

var cacheData;
$.post({.....
         success: function(data){
                  if (data !== cacheData){
                     //data has changed (or it's the first call), save new cache data and update div
                   cacheData = data;
                   $('#yourdiv').html(data);
                   }else{
                   //do nothing, data hasan't changed

This is just an example, you should adapt it to suit your needs (and the structure of data returned)
