react 路由之react-router-dom

1安裝react-router-dom
npm install react-router-dom --save-dev //這裏可使用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";
//分別添加兩個頁面
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 路由的跳轉
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 隱式傳參
<Link to={{ pathname:'/home',state:{ type: 'id' }}} >home</Link> 
query 隱式傳參
<Link to={{ pathname:'/home',query:{ type: 'id' }}} >home</Link> 
 {/* 離開頁面時提示*/}
 <Prompt message="您肯定要離開該頁面嗎?" />

方法跳轉
goHome() {
   this.props.history.push({
      pathname: '/Home',
      state: {
	 id: 3
	   }
	})
}

//子頁面 接受傳值 (不一樣方式下的接受方式)

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

};
