然后再新建一个路由组件,命名为“Router.js”,并编写如下代码: import React from 'react'; import {HashRouter, Route, Switch} from 'react-router-dom'; import Home from '../home'; import Detail from '../detail'; const BasicRoute = () => ( <HashRouter> <Switch> <Route exact path="/"...
<Switch>是唯⼀的因为它仅仅只会渲染⼀个路径。相⽐之下（不使⽤<Switch>包裹的情况下），每⼀个被location匹配到的<Route>将都会被渲染。安装 ⾸先进⼊项⽬⽬录，使⽤npm安装react-router-dom：npm install react-router-dom --save-dev //这⾥可以使⽤cnpm代替npm命令 基本操作 然后我们...
Switch 组件是 React Router 的核心组件之一,它的主要作用是匹配和渲染路由。Switch 组件会遍历其所有的子元素(即 Route 或 Redirect 组件),并只渲染第一个与当前 URL 匹配的子元素。 下面是一个简单的例子: ```jsx import { BrowserRouter as Router, Route, Switch } from 'react-router-dom'; function Ap...
Occasionally, however, we want to pick only one<Route>to render. If we’re at/aboutwe don’t want to also match/:user(or show our “404” page). Here’s how to do it withSwitch: import { Route, Switch }from"react-router"; let routes=(<Switch> <Route exact path="/"> <Home ...
import { Switch, Route } from "react-router-dom"; //正确的引用方式 import { Routes ,Route } from 'react-router-dom'; 在react官网中搜索路由,里面的示例写法在v6版本中已经不生效了。 下面是react官网路由的旧写法: import React, { Suspense, lazy } from 'react'; ...
react-router-dom switch & match <Route>or<Redirect>that matches the location. If the URL is/about, then<About>,<User>, and<NoMatch>will all render because they all match the path. This is by design, allowing us to compose<Route>s into our apps in many ways, like sidebars and ...
1. 使用 <Routes> 而不是 <Switch> 修复“‘Switch’ is not exported from ‘react-router-dom'” 错误的一种方法是将<Switch>替换为<Routes>。 让我们来看一个示例,看看如何将路由代码从 React Router 版本 5 中已废弃的<Switch>组件更新为 React Router 版本 6 中的新<Routes>组件。
"react-router-dom": "^5.3.0", 在之前的react 项目中我们通过yarn add react-router-dom 引入react-router-dom文件 导入的文件的版本是5.3.0 然后再<App /> 这个组件中,我们这样写: import React from 'react' import { BrowserRouter as Router,Route,Switch } from 'react-router-dom'; ...
<Router> <Switch> <HomePage> <Switch> <ErrorBoundary> <Route exact path={'/'} component={InfoShow} /> </ErrorBoundary> </Switch> </HomePage> <CompanyHome> <Switch> <ErrorBoundary> <Route path={ '/companyHome/companyBaseInfo'} component={CompanyBaseInfo} /> </ErrorBoundary> </Switch...
踩坑记录:react-router-dom 从 v6.x 版本开始,移除了Switch,需要做以下变更: 之前:import { Switch, Route } from "...
