二次封装NavLink（React实现）

news2024/9/21 5:31:26

实现思路：

1、定义一个普通组件

2、普通组件内使用NavLink

3、传递参数给定义的普通组件并实现效果

代码实现：

App.jsx

import React, { Component } from "react";
import About from "../src/Pages/About";
import Home from "../src/Pages/Home";
import MyNavLink from "./Compentens/MyNavLink";
import { NavLink, Route, Redirect } from "react-router-dom";
import "./App.css";

export default class App extends Component {
  render() {
    return (
      <div>
        <h1>React Router Demo</h1>
        <div className="list-group">
          {/* 开始封装 */}
          {/*  <MyNavLink to="/home">Home</MyNavLink> ===  
               <MyNavLink to="/home" children="Home"/> */}
          <MyNavLink to="/home">Home</MyNavLink>
          <MyNavLink to="/about">About</MyNavLink>
        </div>
        <div>
          {/* 注册路由 */}
          <Route path="/home" component={Home}></Route>
          <Route path="/about" component={About}></Route>
          {/* 路由重定向 */}
          <Redirect to="/home"></Redirect>
        </div>
      </div>
    );
  }
}

MyNavLink.jsx

import React, { Component } from "react";
import { NavLink } from "react-router-dom";

export default class MyNavLink extends Component {
  render() {
    console.log(this.props);
    return (
      <NavLink
        activeClassName="aiguigu"
        className="list-group-item w-25"
        {...this.props}
      />
    );
  }
}

Home.jsx

import React, { Component } from "react";
export default class index extends Component {
  render() {
    return (
      <div>
        <h3>我是Home的内容</h3>  
      </div>
    );
  }
}

About.jsx

import React, { Component } from 'react'
export default class index extends Component {
  render() {
    console.log('我是About的内容',this.props);
    return (
      <h3>我是About的内容</h3>
    )
  }
}
