uniapp下拉刷新onPullDownRefresh

"path": "pages/index/index",
			"style": {
				"navigationBarTitleText": "notebook",
				"enablePullDownRefresh": true
				
			}

需要先将这个功能给开启

//开启下拉刷新
			onPullDownRefresh(){
				console.log("下拉刷新了……");
				this.refresh=this.refresh+20
				console.log(this.refresh);
				
				uniCloud.callFunction({
					name:"refresh_data",
					data:{
						num:this.refresh
					}
				}).then(res=>{
					console.log(res);
					this.listarr = res.result.data
					console.log(this.listarr);
					//将数据进行重新排列，按照正序
					this.listarr.sort((a, b) => {
						return a._id.localeCompare(b._id);
					});
					
					// 数据存储到本地
					uni.setStorageSync('note', this.listarr);
					this.note = this.listarr
				})
				uni.stopPullDownRefresh()//暂停下拉刷新
				this.refreshvalue=false//用于控制刷新之后的位置
			},

onPullDownRefresh()与onload()同级
