success: function (data) {

if (data > 0) {
obj.innerHTML = (data);

                        obj.enable = false;
                    } else {
                        alert(data);
                    }

    string sql = "update Pfxh set PfDing = PfDing + 1 where PfId=" + id;
    string Connstring = SqlHelper.GetSqlConnection(); ;

    SqlConnection sqlconn = new SqlConnection(Connstring);
    sqlconn = new SqlConnection(Connstring);
    sqlconn.Open();
    SqlCommand sqlcom = new SqlCommand(sql, sqlconn);
