微信小程序云开发上传图片和数据，我想知道为啥我最后db.add里面的imgs：that.data.imgs获取不到data里面的数组

Question

```javascript
submit: function (e) {
    const that = this;
    wx.showLoading({
      title: '发布中',
    });
    var h = that.data.tempFilePaths.length;
    var imgs =[];
    for (var i = 0; i<=h; i++) {
      var timestamp = Date.parse(new Date());
      var date = new Date(timestamp);
      var Y =date.getFullYear();
      var M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1);
      var D = date.getDate() < 10 ? '0' + date.getDate() : date.getDate(); 
      var hour = date.getHours();
      var min = date.getMinutes();
      var sec = date.getSeconds();
      var i2 = i+1;
      if(i<h){
        wx.cloud.uploadFile({
          cloudPath: 'cloudimg/' + 'img' + '[' + h + '.' + i2 +']:'
          +Y+'-'+M+'-'+D+' '+hour+':'+min+':'+sec,
          filePath: that.data.tempFilePaths[i],
          success: res => {
            imgs[imgs.length]=res.fileID;
            console.log(imgs)
            that.setData({imgs:imgs})
            console.log(that.data.imgs)
          },//success: res
          fail: res => {
            wx.hideToast();
            wx.showModal({
              title: '错误提示',
              content: '上传图片失败',
              showCancel: false,
              success: function (res) { }
            })
          }//fail: res
        }); //wx.cloud.uploadFile
      }
      else{
        console.log('成功:'+that.data.imgs)
        db.add({
          data: {
            imgs:this.data.imgs,
            title: this.data.input1,
            price: this.data.input2,
            oprice: this.data.input3,
            details: this.data.input4,
          },
          success: res => {
            wx.showToast({
              title: '发布成功',
            })
          }//success:res
        }) //db.add
      }
    }//for (var i = 0; i < h; i++)
  },

```

检查下以下情况：
1、that.data.tempFilePaths.length是什么值？
2、第一次跑是跑if(i<h)还是跑else，加debugger看看
