1、新增知識點
/* react路由的配置: 1、找到官方文檔 https://reacttraining.com/react-router/web/example/basic 2、安裝 cnpm install react-router-dom --save 3、找到項目的根組件引入react-router-dom import { BrowserRouter as Router, Route, Link } from "react-router-dom"; 4、復制官網文檔根組件里面的內容進行修改 (加載的組件要提前引入) <Router> <Link to="/">首頁</Link> <Link to="/news">新聞</Link> <Link to="/product">商品</Link> <Route exact path="/" component={Home} /> <Route path="/news" component={News} /> <Route path="/product" component={Product} /> </Router> exact表示嚴格匹配 react動態路由傳值 1、動態路由配置 <Route path="/content/:aid" component={Content} /> 2、對應的動態路由加載的組件里面獲取傳值 this.props.match.params 跳轉:<Link to={`/content/${value.aid}`}>{value.title}</Link> react get傳值 1、獲取 this.props.location.search */
2、案例實現路由配置
import React, { Component } from 'react'; import { BrowserRouter as Router, Route, Link } from "react-router-dom"; import './assets/css/index.css' import Home from './components/Home'; import News from './components/News'; import Product from './components/Product'; class App extends Component { render() { return ( <Router> <div> <header className="title"> <Link to="/">首頁</Link> <Link to="/news">新聞</Link> <Link to="/product">商品</Link> </header> <br /> <hr /> <br /> <Route exact path="/" component={Home} /> <Route path="/news" component={News} /> <Route path="/product" component={Product} /> </div> </Router> ); } } export default App;
3、動態路由以及獲取傳值案例
import React, { Component } from 'react'; import { Link } from "react-router-dom"; class Product extends Component { constructor(props) { super(props); this.state = { list:[ { aid:'11', title:'我是商品1111' }, { aid:'222', title:'我是商品222' }, { aid:'3', title:'我是商品333' }, { aid:'4', title:'我是商品4444' } ] }; } //生命周期函數 componentDidMount(){ // this.props.location.search //獲取get傳值 console.log(url.parse(this.props.location.search,true)); var query=url.parse(this.props.location.search,true).query; console.log(query) } render() { return ( <div> 我是商品組件 <ul> { this.state.list.map((value,key)=>{ return ( <li key={key}> <Link to={`/productcontent?aid=${value.aid}`}>{value.title}</Link> </li> ) }) } </ul> </div> ); } } export default Product;
