tableData，noticeData 是两个长二维数组

        $.ajax({
          url: "/admin/samproofing/confirmPieces",
          type: "POST",
          data: {
            "ym": ym1,
            "papertype":paper_type,
            "person_data": that.tableData,
            "notice_data": that.noticeData,
            "_token":'{{csrf_token()}}'
          },
          dataType:'json',
          success: function (res) {
            if(res.code==1){
              //that.tableData = res.data;
              //打样通知单data
              // that.noticeData = res.data;
            }
          }
        });

改成下面这样就不会了！

        $.ajax({
          url: "/admin/samproofing/confirmPieces",
          type: "POST",
          data: {
            "ym": ym1,
            "papertype":paper_type,
            "person_data": JSON.stringify(that.tableData),
            "notice_data": JSON.stringify(that.noticeData),
            "_token":'{{csrf_token()}}'
          },
          dataType:'json',
          success: function (res) {
            if(res.code==1){
              //that.tableData = res.data;
              //打样通知单data
              // that.noticeData = res.data;
            }
          }
        });
