        that.setData({
          polyline: [{
            points: points,
            color: "#0091ff",
            width: 6
          }]
        });
        if (data.paths[0] && data.paths[0].distance) {
          that.setData({
            distance: data.paths[0].distance + '米'
          });
        }
        if (data.paths[0] && data.paths[0].duration) {
          that.setData({
            cost: parseInt(data.paths[0].duration / 60) + '分钟'
          });
        }
      },
      fail: function (info) {
      }
    })
  },

我把代码里的origin和destination直接写成数值那样，polyline就会画出。

但是！！

写成注释掉的那个状态就画不出来！！可是看AppData里的返回数据，that.data.nowplacelongitude对应的就是116.352622，that.data.nowplacelatitude对应的就是39.993029，that.data.toplace.longitude就是116.352091，that.data.toplace.latitude对应的是39.990091啊。。。。

纠结了三天了，不知道要写成什么样子

所以动态加载要写成什么样子，请告知，感激不尽。
