前端分页与瀑布流最佳实践笔记 - React Antd 版

1. 分页与瀑布流对比

分页（Pagination）瀑布流（Infinite Scroll）
展示方式按页分批加载，有明确页码控件滚动到底部时自动加载更多内容，无明显分页
用户控制用户可主动翻页和跳转到任意页用户只能通过滚动浏览，无法直接跳转
数据加载时机用户点击翻页按钮时加载滚动接近底部时自动加载
适用场景数据量大且需精准定位（电商、后台管理系统）信息流浏览（社交媒体、图片墙）
体验特点更可控、易跳转，适合严肃场景更流畅、自然，适合娱乐、轻松浏览
技术实现通过current和pageSize参数请求监听滚动事件，触发加载

核心区别：分页更适合管理和精准查找，瀑布流更适合浏览体验和沉浸式内容。

2. 分页实现 - React Antd

基本实现

import { Table, Pagination } from 'antd';
import { useState, useEffect } from 'react';
import axios from 'axios';function PaginatedTable() {const [data, setData] = useState([]);const [loading, setLoading] = useState(false);const [pagination, setPagination] = useState({current: 1,pageSize: 10,total: 0});const fetchData = async (params = {}) => {setLoading(true);try {const response = await axios.get('/api/items', {params: {page: params.current || pagination.current,pageSize: params.pageSize || pagination.pageSize}});setData(response.data.items);setPagination({...pagination,current: params.current || pagination.current,total: response.data.total});} catch (error) {console.error('Error fetching data:', error);} finally {setLoading(false);}};useEffect(() => {fetchData();}, []);const handleTableChange = (paginate) => {fetchData({current: paginate.current,pageSize: paginate.pageSize});};const columns = [// 定义列{ title: 'Name', dataIndex: 'name', key: 'name' },{ title: 'Age', dataIndex: 'age', key: 'age' },// ...其他列];return (<Tablecolumns={columns}dataSource={data}pagination={pagination}loading={loading}onChange={handleTableChange}rowKey="id"/>);
}

分页优化技巧

  1. 缓存已加载的页面数据
const [cachedData, setCachedData] = useState({});const fetchData = async (params = {}) => {const current = params.current || pagination.current;const pageSize = params.pageSize || pagination.pageSize;const cacheKey = `${current}-${pageSize}`;// 检查缓存中是否已有此页数据if (cachedData[cacheKey]) {setData(cachedData[cacheKey]);return;}setLoading(true);try {const response = await axios.get('/api/items', {params: { page: current, pageSize }});// 更新数据和缓存setData(response.data.items);setCachedData({...cachedData,[cacheKey]: response.data.items});setPagination({...pagination,current,total: response.data.total});} catch (error) {console.error('Error:', error);} finally {setLoading(false);}
};
  1. 预加载下一页数据
const prefetchNextPage = (current, pageSize) => {const nextPage = current + 1;const cacheKey = `${nextPage}-${pageSize}`;// 如果下一页已缓存或正在加载，则不预加载if (cachedData[cacheKey] || loading) return;// 静默加载下一页axios.get('/api/items', {params: { page: nextPage, pageSize }}).then(response => {setCachedData({...cachedData,[cacheKey]: response.data.items});}).catch(err => {console.error('Prefetch error:', err);});
};// 在数据加载完成后调用预加载
useEffect(() => {if (!loading && data.length > 0) {prefetchNextPage(pagination.current, pagination.pageSize);}
}, [data, loading]);
  1. 处理搜索和筛选
import { Table, Pagination, Input, Form, Button, Select } from 'antd';
import { debounce } from 'lodash';function EnhancedTable() {// ...之前的状态const [filters, setFilters] = useState({});// 使用防抖处理搜索const handleSearch = debounce((searchText) => {setFilters(prev => ({ ...prev, searchText }));fetchData({ current: 1 }); // 搜索时重置到第一页}, 300);const fetchData = async (params = {}) => {setLoading(true);try {const response = await axios.get('/api/items', {params: {page: params.current || pagination.current,pageSize: params.pageSize || pagination.pageSize,...filters // 添加所有筛选条件}});// 更新数据和分页信息// ...} catch (error) {console.error('Error:', error);} finally {setLoading(false);}};return (<><Form layout="inline" style={{ marginBottom: 16 }}><Form.Item label="搜索"><Input.Search placeholder="输入关键词" onSearch={value => handleSearch(value)}onChange={e => handleSearch(e.target.value)}/></Form.Item><Form.Item label="状态"><Selectplaceholder="选择状态"style={{ width: 120 }}onChange={value => {setFilters(prev => ({ ...prev, status: value }));fetchData({ current: 1 });}}allowClear><Select.Option value="active">活跃</Select.Option><Select.Option value="inactive">非活跃</Select.Option></Select></Form.Item></Form><Table// ...之前的Table属性/></>);
}

3. 瀑布流实现 - React Antd

基于Marker/Cursor的瀑布流

import { List, Spin, message } from 'antd';
import { useState, useEffect, useRef } from 'react';
import InfiniteScroll from 'react-infinite-scroll-component';
import axios from 'axios';function InfiniteScrollList() {const [data, setData] = useState([]);const [loading, setLoading] = useState(false);const [hasMore, setHasMore] = useState(true);const marker = useRef(null);const loadMoreData = async () => {if (loading || !hasMore) return;setLoading(true);try {const response = await axios.get('/api/items', {params: {limit: 20,marker: marker.current}});const newData = response.data.data;if (newData.length === 0) {setHasMore(false);} else {setData([...data, ...newData]);marker.current = response.data.marker;// 如果没有返回marker，说明没有更多数据了if (!response.data.marker) {setHasMore(false);}}} catch (error) {console.error('Error fetching data:', error);message.error('加载失败，请重试');setHasMore(false);} finally {setLoading(false);}};useEffect(() => {loadMoreData();}, []);return (<divid="scrollableDiv"style={{height: 400,overflow: 'auto',padding: '0 16px',border: '1px solid rgba(140, 140, 140, 0.35)'}}><InfiniteScrolldataLength={data.length}next={loadMoreData}hasMore={hasMore}loader={<Spin tip="加载中..." />}endMessage={<div style={{ textAlign: 'center' }}>没有更多数据了</div>}scrollableTarget="scrollableDiv"><ListdataSource={data}renderItem={item => (<List.Item key={item.id}><List.Item.Metatitle={item.title}description={item.description}/></List.Item>)}/></InfiniteScroll></div>);
}

虚拟列表优化

对于大量数据，可以结合虚拟列表以提高性能：

import { List, Avatar, Spin } from 'antd';
import { useState, useEffect, useRef } from 'react';
import VirtualList from 'rc-virtual-list';
import axios from 'axios';function VirtualizedInfiniteList() {const [data, setData] = useState([]);const [loading, setLoading] = useState(false);const [hasMore, setHasMore] = useState(true);const marker = useRef(null);const containerRef = useRef(null);const itemHeight = 47; // 每项的高度const loadMoreData = async () => {if (loading || !hasMore) return;setLoading(true);try {const response = await axios.get('/api/items', {params: {limit: 20,marker: marker.current}});const newData = response.data.data;if (newData.length === 0) {setHasMore(false);} else {setData(prevData => [...prevData, ...newData]);marker.current = response.data.marker;if (!response.data.marker) {setHasMore(false);}}} catch (error) {console.error('Error:', error);setHasMore(false);} finally {setLoading(false);}};useEffect(() => {loadMoreData();}, []);const onScroll = (e) => {if (e.target.scrollHeight - e.target.scrollTop <= e.target.clientHeight + 100) {loadMoreData();}};return (<List>{loading && data.length === 0 ? <Spin /> : null}<VirtualListdata={data}height={400}itemHeight={itemHeight}itemKey="id"onScroll={onScroll}ref={containerRef}>{(item) => (<List.Item key={item.id}><List.Item.Metaavatar={<Avatar src={item.avatar} />}title={item.title}description={item.description}/></List.Item>)}</VirtualList>{loading && data.length > 0 ? (<div style={{ textAlign: 'center', padding: '12px 0' }}><Spin /></div>) : null}</List>);
}

4. 优化策略总结

性能优化

  1. 虚拟滚动：仅渲染可见区域内的元素，大幅提升性能

    // 使用React Window (安装: npm install react-window)
import { FixedSizeList as List } from 'react-window';const Row = ({ index, style }) => (<div style={style}>Row {index}</div>
);const VirtualizedList = () => (<Listheight={400}itemCount={1000}itemSize={35}width={300}>{Row}</List>
);

  2. 数据预取：提前加载下一页数据，提升用户体验

    // 当用户滚动到接近底部时预加载
const handleScroll = (e) => {const { scrollTop, scrollHeight, clientHeight } = e.target;// 当滚动到距离底部20%的位置时预加载if (scrollTop > (scrollHeight - clientHeight) * 0.8) {prefetchNextData();}
};

  3. 请求优化：使用防抖和节流控制请求频率

    import { debounce, throttle } from 'lodash';// 防抖：用于搜索输入
const debouncedSearch = debounce((value) => {fetchData(value);
}, 300);// 节流：用于滚动事件
const throttledScroll = throttle((e) => {handleScroll(e);
}, 200);

用户体验优化

  1. 加载状态反馈

    // 使用骨架屏代替简单的加载指示器
import { Skeleton } from 'antd';{loading ? (<Skeleton active paragraph={{ rows: 4 }} />
) : (<ContentComponent data={data} />
)}

  2. 错误处理与重试

    const [error, setError] = useState(null);const fetchData = async () => {setLoading(true);setError(null);try {// 数据请求...} catch (err) {setError(err.message || '加载失败');} finally {setLoading(false);}
};// 在UI中展示错误信息和重试按钮
{error && (<div className="error-container"><p>{error}</p><Button onClick={fetchData}>重试</Button></div>
)}

  3. 记住滚动位置

    // 保存滚动位置到sessionStorage
const saveScrollPosition = () => {sessionStorage.setItem('scrollPosition', container.current.scrollTop);
};// 组件卸载前保存位置
useEffect(() => {return () => {saveScrollPosition();};
}, []);// 组件挂载时恢复位置
useEffect(() => {const savedPosition = sessionStorage.getItem('scrollPosition');if (savedPosition && container.current) {container.current.scrollTop = parseInt(savedPosition);}
}, []);

5. 最佳实践

分页场景选择

  1. 传统分页（页码导航）适用场景：
    • 后台管理系统
    • 数据表格/数据列表展示
    • 需要精确定位到特定页面的场景
    • 数据总量明确的场景
  2. 瀑布流/无限滚动适用场景：
    • 社交媒体信息流
    • 图片/卡片展示墙
    • 新闻阅读页面
    • 产品类目浏览
    • 强调浏览体验的场景

实现决策树

选择分页方式
├── 需要精确页码跳转？
│   ├── 是 → 使用传统分页 (Pagination)
│   │   └── 数据量大？
│   │       ├── 是 → 启用虚拟滚动
│   │       └── 否 → 使用标准Table组件
│   └── 否 → 考虑瀑布流/无限滚动
│       ├── 需要保持列表位置？
│       │   ├── 是 → 使用marker/cursor分页
│       │   └── 否 → 可使用offset分页
│       └── 列表项数量可能很大？
│           ├── 是 → 必须启用虚拟滚动
│           └── 否 → 可以使用简单InfiniteScroll
