深入了解React（十七、路由3-HashRouter ）

1、安装：yarn add [email protected]
2、引入：import { HashRouter as Router, Route } from ‘react-router-dom’;

import React from 'react';
import ReactDOM from 'react-dom';
import {HashRouter as Router, Route, Link} from 'react-router-dom';

import 'font-awesome/css/font-awesome.min.css';
import './index.css';
import './index.scss';

class A extends React.Component {
    constructor(props) {
        super(props);
    }

    render() {
        return (
            <div>
                Component A
            </div>
        )
    }
}

class B extends React.Component {
    constructor(props) {
        super(props);
    }

    render() {
        return (
            <div>Component B</div>
        )
    }
}

class Wrapper extends React.Component {
    constructor(props) {
        super(props);
    }

    render() {
        return (
            <div>
                <p><Link to="/a">组件A</Link></p>
                <p><Link to="/b">组件B</Link></p>
                {this.props.children}
            </div>
        )
    }
}

ReactDOM.render(
    <Router>
        <Wrapper>
            <Route path="/a" component={A}></Route>
            <Route path="/b" component={B}></Route>
        </Wrapper>
    </Router>,
    document.getElementById('app')
);

组件A的路径：http://localhost:8086/dist/#/a
组件B的路径：http://localhost:8086/dist/#/b
