一：简单版本

先 npm i react-router-dom

main.ts中内容替换为

javascript 复制代码

import ReactDOM from 'react-dom/client'
import App from './App.tsx'
import './index.css'
import {
  createBrowserRouter,
  RouterProvider,
  Route,
  Link,
} from "react-router-dom";

const router = createBrowserRouter([
  {
    path: "/",
    element: (
      <div>
        <h1>Hello World</h1>
        <Link to="about">About Us</Link>
      </div>
    ),
  },
  {
    path: "about",
    element: <div>About</div>,
  },
]);

ReactDOM.createRoot(document.getElementById('root')!).render(
  // <React.StrictMode>
  //   <App />
  // </React.StrictMode>,
  <RouterProvider router={router} />
)

方式二：

// 页面、编程式跳转

main.ts

typescript 复制代码

import ReactDOM from 'react-dom/client'
import App from './App.tsx'
import Page1 from './pages/page1.tsx'
import Page2 from './pages/page2.tsx'
import './index.css'
import {
  createBrowserRouter,
  RouterProvider,
  Route,
  Link,
} from "react-router-dom";

const router = createBrowserRouter([
  {
    path: "/",
    element: <Page1 />,
  },
  {
    path: "about",
    element: <Page2 />,
  },
]);

ReactDOM.createRoot(document.getElementById('root')!).render(
  // <React.StrictMode>
  //   <App />
  // </React.StrictMode>,
  <RouterProvider router={router} />
)

page1.tsx

typescript 复制代码

import { useNavigate } from 'react-router-dom'
 const  page1 = () => {
    const naviagte = useNavigate()
    return <div>
        page1
        <button onClick={() => {
            naviagte('/about')
        }}>去page2</button>
    </div>
}

export default page1

page2.tsx

typescript 复制代码

const  page2 = () => {
    return <div>
        page2
    </div>
}

export default page2
