[React] React Router: IndexRoute

標籤：

IndexRoute allows us to define a default child component to be rendered at a specific route when no other sub-route is available.

 

When Home page display, we also make About component as default Route to dsiplay, only when use click Contact link, then swith to Contact Route:

import React from ‘react‘;import {hashHistory, Route, Router, Link, IndexRoute} from ‘react-router‘;const Home = (props) => <div><h1>Home</h1><Links></Links>{props.children}</div>;const About = () => <div><h1>About</h1></div>;const Contact = () => <div><h1>Contact</h1></div>;const Links = () =>    <nav >        <Link activeStyle={{color: ‘green‘}} to="/">Home</Link>        <Link activeClassName="active" to="/contact">Contact</Link>    </nav>;class App extends React.Component {    render(){        return(            <Router history={hashHistory}>                <Route path="/" component={Home}>                    <IndexRoute component={About}></IndexRoute>                    <Route path="contact" component={Contact}></Route>                </Route>            </Router>        );    }}export default App;
