reactjs - React js 做通用 header

Question

我是 ReactJS 新手。我需要有一个通用标题并根据路线变化更改标题。我需要创建一个 header.jsx 文件并导入它吗？否则，如何使用路由渲染 header (公共(public)文件)？

我的路由部分如下所示:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App.jsx';
import Home from './Home.jsx';
import { Router, Route, Link, browserHistory, IndexRoute  } from 'react-router';

ReactDOM.render((
    <Router history = {browserHistory}>
        <Route path = "/home" component = {Home} />
        <Route path = "/" component = {App}>
        </Route>
    </Router>
));

Answer 1

这应该有效:

header.jsx:

class Header extends Component {
  render() {
    return (<div>Your header</div>);
  }
}

第一页.jsx:

class FirstPage extends Component {
  render() {
    return (<div>First page body</div>);
  }
}

第二页.jsx

class SecondPage extends Component {
  render() {
    return (<div>Second page body</div>);
  }
}

app.jsx:

import Header from './header.jsx';

class App extends Component {
  render() {
    return (
      <div>
        <Header />
        {this.props.children}
      </div>
    );
  }
}

web-app.jsx:

import App from './app.jsx';
import FirstPage from './first-page.jsx';
import SecondPage from './second-page.jsx';

ReactDOM.render(
  <Router history = {browserHistory}>
    <Route path = "/" component = {App}>
      <Route path = "/first" component = {FirstPage}>
      <Route path = "/second" component = {SecondPage}>
    </Route>
  </Router>
);
