语法:const navigate=uaeNavigate() navigate('/article') 使用场景:登录后跳转 import { Link,useNavigate }from"react-router-dom"constLogin = ()=>{constnavigate =useNavigate()return<> navigate('/article')}>命令式跳转2 </>} exportdefaultLogin 四、导航传参 1.searchParams传参 navigate('/art...
2、URL 参数 将状态保存到浏览器 URL 中,当我们初始化组件时,会从 URL 参数中读取初始值。 PS:由于 URL 长度限制,对于比较简单的数据此方法适用。 import { useEffect, useState } from "react"; import "./styles.css"; import qs from "qs"; import { createBrowserHistory } from "history"; export ...
// counter.jsimportReact,{useState}from"react";exportdefaultfunctionCounter(){const[count,setCount]=useState(0);constincrement=()=>setCount(count=>count+1);constdecrement=()=>setCount(count=>count-1);return(-{count}+);} 这一次,即使您的计数器仍然工作,第一个测试也将被打破。Enzyme会报错,函...

重定向 使用:Navigate 懒加载 使用:lazy,且需要包在loading提示组件中。 路由文件中代码如下: import {Navigate}from"react-router-dom"import React,{lazy}from"react"import Homefrom"../views/Home"constAbout= lazy(()=>import("../views/About"));//懒加载模式的组件写法,外面需要套一层loading 的提示加...
return '禁止跳转到指定的errorUrl页面,确定继续跳转吗' } else { return true; // 符合跳转的条件,释放路由,路由正常跳转 } } render() { const { isHoldUpRouter } = this.state; return ( <Button onClick={this.handleRouterSwitch}>跳转路由</Button> <Button...
useSearchParams用于读取和修改当前位置的 URL 中的查询字符串。与React的useState钩子类似,React Router的useSearchParams钩子返回一个包含两个元素的数组:第一个是当前位置的搜索参数,后者是一个可用于更新它们的函数: import{ useSearchParams }from'react-router-dom';constApp= () => {const[searchParams, set...

In the context of a React JS application, routing allows us to display different components based on the URL. This enables users to navigate between various views without the need to refresh the entire page. Setting Up a React Project Before we delve into routing in React JS, let’s begin...
