Ant Design+react 路由跳转
今天我们来继续探讨react的路由跳转
首先,创建router文件夹中的index
import { lazy } from "react";
import { Outlet,useRoutes } from 'react-router-dom';
//引入页面,引用了路由懒加载
const One = lazy(() => import('../pages/one'));
const Two = lazy(() => import('../pages/two'));
const Three = lazy(() => import('../pages/three'));
//设置页面的路由路径
const routes = [{path: '/one',element: <One/>,},{path: '/two',element: <Two/>,children: []},{path: '/three',element: <Three/>,}
];
const WrappedRoutes = () => {return useRoutes(routes);};export default WrappedRoutes;
之后就是App.js页面了,我的layout是写在app.js里的,所以要在app.js进行设置
import React, { useState,lazy } from 'react';
import {MenuFoldOutlined,MenuUnfoldOutlined,UploadOutlined,UserOutlined,VideoCameraOutlined,
} from '@ant-design/icons';
import { Layout, Menu, Button, theme } from 'antd';
import WrappedRoutes from './router/index'; // 引入路由表
import { useLocation, useNavigate,Routes, Route } from 'react-router-dom';
const One = lazy(() => import('./pages/one'));
const Two = lazy(() => import('./pages/two'));
const Three = lazy(() => import('./pages/three'));
const { Header, Sider, Content } = Layout;const App: React.FC = () => {const [collapsed, setCollapsed] = useState(false);const {token: { colorBgContainer },} = theme.useToken();const navigate = useNavigate();const { pathname } = useLocation(); // 获取当前urlconst handleClick = (e: any) => {// 获取当前点击事件的key值,key值就是我们给页面配置的路由啦console.log('key', e.key);navigate(e.key,{replace:true}); // 实现跳转}return (<Layout><Sider trigger={null} collapsible collapsed={collapsed}><div className="demo-logo-vertical" /><Menutheme="dark"mode="inline"selectedKeys={[pathname]}onClick={handleClick} //给侧边栏item设置点击事件defaultSelectedKeys={['1']}items={[{key: '/one',icon: <UserOutlined />,label: 'nav 1',},{key: '/two',icon: <VideoCameraOutlined />,label: 'nav 2',},{key: '/three',icon: <UploadOutlined />,label: 'nav 3',},]}/></Sider><Layout><Header style={{ padding: 0, background: colorBgContainer }}><Buttontype="text"icon={collapsed ? <MenuUnfoldOutlined /> : <MenuFoldOutlined />}onClick={() => setCollapsed(!collapsed)}style={{fontSize: '16px',width: 64,height: 64,}}/></Header><Contentstyle={{margin: '24px 16px',padding: 24,minHeight: 280,background: colorBgContainer,}}>{/*路由出口 */}<Routes><Route exact path="/one" element={<One />} /><Route exact path="/two" element={<Two />} /><Route exact path="/three" element={<Three />} /></Routes></Content></Layout></Layout>);
};export default App;
到这里还有最重要的一步,因为我们这是的路由懒加载,这个时候跳转是会报错的
一直出现不能读到pathname,从<router>
的时候就出现这个问题,那么问题估计出现在<router>
这个标签上。找不到路径名,那就是没有找到地址于是我把<router>
换成了<BrowserRouter>
,就可以了。
import React,{ Suspense } from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';
import { BrowserRouter } from 'react-router-dom';
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(<React.StrictMode><BrowserRouter>{/* 在使用组件懒加载的时候,在外面套一个react的组件:Suspense ,否则会报错没有 */}<Suspense><App /></Suspense></BrowserRouter></React.StrictMode>
);
reportWebVitals();
最后,在使用路由懒加载的同时,一定要记得使用<Suspense>嵌套,否则还是会报错,切记切记
