本文介绍如何使用 React Router 实现嵌套路由。通过简单的示例代码展示了如何定义和渲染嵌套组件，以及如何在导航链接中激活相应的样式。

Since react-router routes are components, creating nested routes is as simple as making one route a child of another in JSX.

Make the nested component:

class App extends React.Component {
    render(){
        return(
            <Router history={hashHistory}>
                <Route path="/" component={Home}>
                    <Route path="about" component={About}>
                        <Route path="contact" component={Contact}></Route>
                    </Route>
                </Route>
            </Router>
        );
    }
}

Change the path:

const Links = () =>
    <nav >
        <Link activeStyle={{color: 'green'}} to="/">Home</Link>
        <Link activeStyle={{color: 'green'}} to="/about">About</Link>
        <Link activeClassName="active" to="/about/contact">Contact</Link>
    </nav>;

Pass the props.children to the nested component:

const Home = (props) => <div><h1>Home</h1><Links></Links>{props.children}</div>;
const About = (props) => <div><h1>About</h1>{props.children}</div>;
const Contact = () => <div><h1>Contact</h1></div>;

----------------

import React from 'react';
import {hashHistory, Route, Router, Link} from 'react-router';

// About is the child of home, to display the about, we need to access
// props.children
const Home = (props) => <div><h1>Home</h1><Links></Links>{props.children}</div>;
const About = (props) => <div><h1>About</h1>{props.children}</div>;
const Contact = () => <div><h1>Contact</h1></div>;


const Links = () =>
    <nav >
        <Link activeStyle={{color: 'green'}} to="/">Home</Link>
        <Link activeStyle={{color: 'green'}} to="/about">About</Link>
        <Link activeClassName="active" to="/about/contact">Contact</Link>
    </nav>;

class App extends React.Component {
    render(){
        return(
            <Router history={hashHistory}>
                <Route path="/" component={Home}>
                    <Route path="about" component={About}>
                        <Route path="contact" component={Contact}></Route>
                    </Route>
                </Route>
            </Router>
        );
    }
}

export default App;
