When we pull down, we need to get the data again. At this time, when it succeeds, we need to close the pull down to refresh

getVideoList:function(vid){

  wx.showLoading({
    title: '正在加载',
  });
  this.setData({
    vList:""
  })
  // 获取当前vid 下的视频列表
  wx.request({
    url: 'http://localhost:3000/video/group?id='+vid,
    header: {
      'cookie': wx.getStorageSync('cookie')// 默认值
    },
    success:(res)=>{
      console.log(res.data.datas)
      // 取消加载图标
      wx.hideLoading();
      let datas = res.data.datas;
      console.log("data" + datas)
      let index= 0;
    datas = datas.map(item=>{
        item.id = index++;
        return item;
      })
      this.setData({
        vList:datas,
        isTriggered: false
      })
    },
    fail:function(e){
      console.log(e)
    }
  })
},

 

The focus is on the yellow area!
