在React中,可以使用React Router来创建和管理动态路由。以下是一个简单的示例:
npm install react-router-dom
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import Home from './components/Home';
import About from './components/About';
import Contact from './components/Contact';
function App() {
return (
<Router>
<Switch>
<Route exact path="/" component={Home} />
<Route path="/about" component={About} />
<Route path="/contact" component={Contact} />
</Switch>
</Router>
);
}
export default App;
import React from 'react';
const Home = () => <h1>Home</h1>;
export default Home;
import React from 'react';
const About = () => <h1>About</h1>;
export default About;
import React from 'react';
const Contact = () => <h1>Contact</h1>;
export default Contact;
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
ReactDOM.render(<App />, document.getElementById('root'));
现在,您可以通过访问http://localhost:3000/
来查看Home页面,访问http://localhost:3000/about
来查看About页面,访问http://localhost:3000/contact
来查看Contact页面。这样您就成功创建和管理了动态路由。
