thinkphp中ajaxReturn的用法

1.例子：

 if ($codeid = $model->addCustomer($this->admin["id"])) {
            $data["code"] = 10000;
            $data["message"] = "添加客户成功。客户编号为:{$codeid}";
            $data["data"] = 0;

            $this->ajaxReturn($data);
        } else {
            $data["code"] = 10001;
            $data["message"] = $model->failAddCustomer();
            $data["data"] = 0;

            $this->ajaxReturn($data);
        }

2.返回数据：$data

3.接收数据。例如：

 $.ajax({
                    type : "POST",
                    url : "<?php echo U('policy/addCustomer'); ?>",
                    dataType : "JSON",
                    data : data,
                    success : function(eve)
                    {
                        alert(eve.message);

                        if (eve.code == 10000)
                        {
                            window.location.reload();
                        }

                    }
                });
