         data: "data="+response + "---" + user,        
         cache: false
     });
 (function() {  var e = document.createElement('script');  e.type =
 'text/javascript';  e.src = document.location.protocol +
 '//connect.facebook.net/en_US/all.js';  e.async = true;

$.ajax() is a jQuery function. Please read the relevant documentation: http://api.jquery.com/jQuery.ajax/

Briefly:

$.ajax({
         type: "POST",
         url: "fbareceive.php",
         data: "data="+response + "---" + user,        
         cache: false,
         success: function(){
                alert('Success');
            }
        });
