react 路由之react

1安装react-router-dom

npm install react-router-dom --save-dev //这里可以使用cnpm代替npm命令

1 新建router文件

//引入 react-router-dom

import { HashRouter, Route, Switch, BrowserRouter as Router } from "react-router-dom";

//分别添加两个页面

import App from '../App';

import Home from '../Home';

const BasicRoute = () => (

	<Router>

      <Switch>

          <Route exact path="/" component={App} activeClassName="active"/>

          <Route exact path="/home" component={Home} activeClassName="active"/>

      </Switch>

  </Router>

);

export default BasicRoute;

2 index.js

//引入路由

import Router from './router/router';

//首先渲染的component

ReactDOM.render(<Router/>, document.getElementById('root'));
3 路由的跳转

import {

	BrowserRouter as Router,

	Route,

	Link,

	Prompt

} from "react-router-dom";

<Link to="/home">home</Link>

<input type="button" value="Home" onClick={this.goHome.bind(this)}/>

state 隐式传参

<Link to={{ pathname:'/home',state:{ type: 'id' }}} >home</Link>

query 隐式传参

<Link to={{ pathname:'/home',query:{ type: 'id' }}} >home</Link> 
 {/* 离开页面时提示*/}
 <Prompt message="您确定要离开该页面吗?" />
方法跳转
goHome() {

   this.props.history.push({

      pathname: '/Home',

      state: {

	 id: 3

	   }

	})

}
//子页面 接受传值 (不同方式下的接受方式)

componentWillMount() {
   let _id = this.props.match.params.id,
         id = this.props.history.location.state,
        id1 = this.props.history.location.query;
        console.log("准备好了", _id, id, id1);

};
