使用Facebook API的Ajax jQuery

I am trying to parse all the id's of the user likes with jquery. this is what i did but it doesnt work.

 $("#demo").live("click", function () {   

       var url="https://graph.facebook.com/facebookid/likes?access_token=XXXX?callback=?";

        $.getJSON(url, function(item){
         $.each(item.data, function(i,like) {
           var name = like.id;
           $("#dv").append(name);
           });
        });

    });

You can't use simple AJAX ($.get, $.post, $.ajax) for request to another domains. You would read about JSONP... or about FB JA \S \
