文章描述了一个使用Vue.js构建的页面，展示如何通过scroll-view组件实现数据列表的加载、分页以及下拉刷新功能，包括API请求获取数据并处理刷新、滚动到底部加载更多等交互。

在这里插入图片描述

<template>
	<view class="task">
		<scroll-view v-if="dataList.length>0" style="height: calc(100% - 20px);margin:10px 0;" scroll-y="true"
			refresher-enabled="true" :refresher-triggered="triggered" :refresher-threshold="100"
			refresher-background="lightgreen" @refresherpulling="onPulling" @refresherrefresh="onRefresh"
			@scrolltolower="onButtom">
			<view v-for="(item,index) in dataList" :key="index" class="demo">
				<h3>xxxx{{index}}</h3>
			</view>
		</scroll-view>
		<view v-else class="">
			<u-empty text="暂无数据" mode="list"></u-empty>
		</view>

	</view>
</template>

<script>
	import request from "@/utils/http.js"
	export default {
		data() {
			return {
				pageNo: 1,
				pageSize: 10,
				totalPage: 0,
				dataList: [],
				triggered: false,
			};
		},
		onShow() {
			this.dataList = []
			this.getList();
		},
		methods: {
			getList() {
				let userId = uni.getStorageSync('userId')
				var parms = {
					userId: userId,
					pageSize: this.pageSize,
					pageNo: this.pageNo
				}
				request.get('/接口地址t', parms, {
					Headers: 'json'
				}).then(res => {
					if (res.page) {
						//判断是否为第一页
						if (this.pageNo == 1) {
							//赋值
							this.dataList = res.page.list
							var total = res.page.count
							var pageSize = this.pageSize
							this.totalPage = total % pageSize == 0 ? total / pageSize : total / pageSize + 1
						} else {
							//拼接数据concat
							this.dataList = this.dataList.concat(res.page.list)
						}
					} else {
						//否则置空
						this.dataList = []
					}
				})
			},
			// 下拉刷新状态
			onPulling() {
				var that = this;
				if (!this.triggered) {
					this.triggered = true;
					setTimeout(() => {
						that.triggered = false;
					}, 1000)
				}
			},

			// 自定义下拉刷新被触发
			onRefresh(e) {
				this.pageNo = 1
				this.getList()
			},
			// 滚动到底部
			onButtom() {
				if (this.totalPage > this.pageNo + 1) {
					this.pageNo += 1
					this.getList()
				} else {
					uni.showToast({
						mask: true,
						title: "没有更多了",
						duration: 2000,
						icon: 'none'
					});
				}
			},

		},
	};
</script>
