        $.ajax({
            url:"list.php",
            dataType: "json",
            success: function(resp){
                for(var i=0;i                    $('#goods_list').append(
                      "
" + resp[i]["name"] + "
"
                      +

                      "
Price： NT$" + resp[i]["price"] + "
"
                      +
                      resp[i]["description"]
                      +
                      "
 Add | More"
                      +"
"
                    );
                }

                var resp2 = resp;

            }
        });

        $('body').append(resp2[0]["price"]);

And FireBug said:

ReferenceError: resp2 is not defined
$('body').append(resp2[0]["price"]);

How can I use $.ajax success data in somewhere else? (outside the $.ajax function)

The concept is similar to "Global Variables".
