$this->data = $Data->field(id,datupian)->select();
//将数组变成json类型
echo JSON(array("fabiao"=>$this->data));输出以下{"fabiao":[{"ifcheck":"1","content":"ww","datupian":"/thinkphp322/Uploads/1400145614.jpg","jingdu":"122","weidu":"22","deviceid":"406C8F4DC2AB","time":"0"},{"ifcheck":"1","content":"eee","datupian":"/thinkphp322/Uploads/1400145802.jpg","jingdu":"122","weidu":"22","deviceid":"406C8F4DC2AB","time":"0"},{"ifcheck":"0","content":"ww","datupian":"/thinkphp322/Uploads/1400146788.jpg","jingdu":"122","weidu":"22","deviceid":"406C8F4DC2AB","time":"0"},{"ifcheck":"1","content":"eee","datupian":"/thinkphp322/Uploads/1400147276.jpg","jingdu":"122","weidu":"22","deviceid":"406C8F4DC2AB","time":"0"},{"ifcheck":"1","content":"ee","datupian":"/thinkphp322/Uploads/1400147363.jpg","jingdu":"122","weidu":"22","deviceid":"406C8F4DC2AB","time":"0"},{"ifcheck":"1","content":"wewe","datupian":"/thinkphp322/Uploads/1400147415.jpg","jingdu":"122","weidu":"22","deviceid":"406C8F4DC2AB","time":"0"},{"ifcheck":"1","content":"wwe","datupian":"/thinkphp322/Uploads/1400147699.jpg","jingdu":"122","weidu":"22","deviceid":"406C8F4DC2AB","time":"0"},{"ifcheck":"1","content":"weewew","datupian":"/thinkphp322/Uploads/1400147872.jpg","jingdu":"122","weidu":"22","deviceid":"406C8F4DC2AB","time":"0"},{"ifcheck":"1","content":"wewe","datupian":"/thinkphp322/Uploads/1400154734.jpg","jingdu":"122","weidu":"22","deviceid":"406C8F4DC2AB","time":"0"}]}我没看到id字段哈最佳答案
