        {"b":[{"data.s":"{\"key\":[{\"id\":\"76371\"," +"\"name\":\"华丽蜕变\"," +
                         "\"inputtime\":\"2016-04-28 00:00:00.0\"," +"\"titlecolor\":\"\",\"tuwen\":\"0\"}]}"
        }]}
    ]}
//console.log(data["res"]["b"]["data.s"]["key"]["id"]);
alert(typeof data["res"][1]["b"][0]["data.s"]);
alert(JSON.parse(data.res[1].b[0]["data.s"]).key[0].id);
