React路由的使用
使用React路由之前,我们需要先安装 react-router-dom这个包。比如:
1
| yarn add react-router-dom
|
代码举例:
(1)index.html
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
| <!DOCTYPE html> <html lang="en">
<head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> </head>
<body> <div id="app"></div> </body>
</html>
|
(2)main.js:
1 2 3 4 5 6 7 8 9 10
|
import React from "react"; import ReactDOM from "react-dom";
import App from "./App.jsx";
ReactDOM.render(<App />, document.getElementById("app"));
|
(3)app.jsx:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 < |
