react 路由之react-router-dom

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);

};
