使用方法

ajaxPostJson("/ProductInfo/GetClientConfig", { platformId:plateformId }, function (data) {
                var json=data.data;
                if (data.isSuccess) {
                    $('.wrap').text( formatJson(json) );
                }
                else {

                }
            });
