我网页知识很基础，帮别人写个微信小程序碰到一个很奇怪的问题

db.collection('bikeManage').get()
      .then(res => {
        that.setData({
          bikeList: []
        })
        var bikeLists = [];
        for (var i = 0; i < res.data.length; i++) {
          list.bikeID = res.data[i].bikeID;
          //console.log(res.data[i].bikeID)
          if (res.data[i].showOnMap) {
            list.showOnMap = "正常";
          } else {
            list.showOnMap = "未投入";
          }
          console.log(list)
          bikeLists.push(list);
        }

不懂就要问，是我写错了还是怎么回事,不能理解图片的结果
