react 路由安裝及簡單使用
#安裝:npm i react-router-dom@5.0 - S(最新版本為6.0)導入:import { HashRouter as Router, Route, NavLink } from 'react-router-dom'
2.連結使用:
function App() { return (<Router> <div> //exact 精确匹配 <NavLink to='/' exact>首页</NavLink>| <NavLink to='/about' >关于</NavLink> </div> {/* 路由页面 */} <Switch> <Route path="/" exact component={Home}></Route> <Route path="/about" component={About}></Route> </Switch> </Router>) } export default App function Home() { return <div>首页页面</div> } function About() { return <div> 关于页面 </div> }
import { HashRouter as Router, Route, NavLink, Redirect, Switch, Prompt, Link } from 'react-router-dom' // NavLink 会比 link自动添加一个active的class function App() { return (<Router> <div> <NavLink to='/' exact>首页</NavLink>| <NavLink to='/about' >关于</NavLink> <NavLink to='/produce/abc'>产品abc</NavLink> <NavLink to='/produce/123'>产品123</NavLink> </div> {/* 路由页面 */} <Switch> <Route path="/" exact component={Home}></Route> <Route path="/about" component={About}></Route> <Route path="/produce/:id" component={Produce}></Route> </Switch> </Router>) } export default App function Produce({ match, history, location }) { // console.log(match); return (<div> <h1>产品{match.params.id}</h1> <button onClick={() => history.goBack()}>返回</button> <button onClick={() => history.push('/')}>回到首页</button> </div>) } function Home() { return <div>首页页面</div> } function About() { return <div>关于页面 </div> }
// 导入路由相关组件 // 导入哈希路由 别名router // Route路由页面 // NvaLink 导航链接 import { HashRouter as Router, Route, NavLink, Redirect, Switch, Prompt, Link } from 'react-router-dom' // NavLink 会比 link自动添加一个active的class function App() { return (<Router> <div> <NavLink to='/' exact>首页</NavLink>| <NavLink to='/about' >关于</NavLink> <NavLink to='/produce/abc'>产品abc</NavLink> <NavLink to='/produce/123'>产品123</NavLink> <NavLink to='/admin'>管理</NavLink> </div> {/* 路由页面 */} <Switch> <Route path="/" exact component={Home}></Route> <Route path="/about" component={About}></Route> <Route path="/produce/:id" component={Produce}></Route> <Route path="/admin" component={Admin}></Route> </Switch> </Router>) } export default App function NoMatch({ location, history }) { return (<div> <h1>404</h1> <p>你爹来咯</p> <p>{location.url}</p> <button onClick={history.goBack}>后退</button> <NavLink to={{ pathname: "/" }}>首页</NavLink> </div>) } function Admin() { return (<div style={{ "display": "flex" }}> <div style={{ width: "200px", boderRight: "1px solid #f0f0f0" }}> <NavLink to="/admin/dash">概览</NavLink><br /> <NavLink to="/admin/orderlist">列表</NavLink> </div> <div> <Route path="/admin/dash" component={Dash}></Route> <Route path="/admin/orderlist" component={OrderList}></Route> <Redirect path='/admin' to="/admin/dash"></Redirect> </div> </div>) } function Dash() { return (<div> 概览 </div>) } function OrderList() { return (<div> 订单列表 </div>) } function Produce({ match, history, location }) { // console.log(match); return (<div> <h1>产品{match.params.id}</h1> <button onClick={() => history.goBack()}>返回</button> <button onClick={() => history.push('/')}>回到首页</button> </div>) } function Home() { return <div>首页页面</div> } function About() { return <div>关于页面 </div> }
