          wx.ready(() => {

            wx.getLocation({
              type: "gcj02", // 默认为wgs84的gps坐标，如果要返回直接给openLocation用的火星坐标，可传入'gcj02'
              success: function(res) {
                var latitude = res.latitude; // 纬度，浮点数，范围为90 ~ -90
                var longitude = res.longitude; // 经度，浮点数，范围为180 ~ -180。
                that.getAddress(latitude, longitude);
              },

                that.$Message.warning("获取位置信息失败");
                that.addRecord();
