ajaxReturn($data) 结果是[{"zbh":"1","pfkpdh":"XK0251712210010","spid":"19464","dj":"3.24786325","sl":"5.00000000","je":"16.24000000","pch":"20170702","row_number":"1"},{"zbh":"2","pfkpdh":"XK0251712210010","spid":"21007","dj":"13.67521368","sl":"5.00000000","je":"68.38000000","pch":"1709137","row_number":"2"}]
怎么是[{}]这是为什么 而不是｛｛｝｝ 这样的 求助 哪里错了
