[英]react router dom library doesn't work for my project
我的名字是拉傑迪普·辛格。 我在我的反應項目中使用 react-router-dom 。 單擊鏈接標簽時,鏈接標簽不起作用。我不明白為什么不起作用。 在瀏覽器中更改 URL 而是一個組件,在 web 應用程序上沒有更改
檢查我的代碼這是我的 Main.js 組件文件代碼
import React, { Fragment } from 'react';
import Foot from './Footer';
import Head from './Header'
import MainContect from './MainContect';
import About from './page/About';
import Book from './page/Book'
import { BrowserRouter as Router, Switch, Route } from "react-router-dom";
function Main() {
return (
// use Fragment
<Fragment>
{/* use BrowserRouter as Router */}
<Router>
{/* out Router use Head componet */}
<Head />
{/* use Switch tag */}
<Switch>
{/* use Route defined Router path */}
<Route path="/" exact >
{/* compnent name */}
<MainContect />
</Route>
<Route path="/book" >
<Book />
</Route>
<Route path="/about" >
<About />
</Route>
</Switch>
{/* out Router use Head componet */}
<Foot />
</Router>
</Fragment>
)
}
export default Main
這是我的 Header.js 組件文件代碼
import React from 'react';
import './css/header.scss';
import { BrowserRouter as Router, Link } from 'react-router-dom';
function Head() {
return (
// Use Router tag wrap all Link in Router
<Router>
<header>
<h1 className='logo'> Sikh Book</h1>
<div className="iconArea">+</div>
<ul className="ulArea">
<li>
{/* Use Link tag for navigation */}
<Link to="/"> Home </Link> </li>
<li>
<Link to="/book">
Book
</Link>
</li>
<li>
<Link to="/about">
About
</Link>
</li>
</ul>
</header>
</Router>
)
}
export default Head
請告訴我的錯誤謝謝你幫助我
您應該只啟動一次 BrowserRouter。 我會在您的組件樹的較高級別執行此操作。 你可以看看這個例子。
// BrowserRouter is the router implementation for HTML5 browsers (vs Native).
// Link is your replacement for anchor tags.
// Route is the conditionally shown component based on matching a path to a URL.
// Switch returns only the first matching route rather than all matching routes.
import {
BrowserRouter as Router,
Link,
Route,
Switch,
} from 'react-router-dom';
import React from 'react';
const Home = () => <h1>Home</h1>;
const About = () => <h1>About</h1>;
// We give each route either a target `component`, or we can send functions in `render` or `children`
// that return valid nodes. `children` always returns the given node whether there is a match or not.
const App = () => (
<Router>
<div>
<Link to="/">Home</Link>{' '}
<Link to={{pathname: '/about'}}>About</Link>{' '}
<Link to="/contact">Contact</Link>
<Switch>
<Route path="/" component={Home} />
<Route path="/about" component={About} />
<Route
path="/contact"
render={() => <h1>Contact Us</h1>} />
<Route path="/blog" children={({match}) => (
<li className={match ? 'active' : ''}>
<Link to="/blog">Blog</Link>
</li>)} />
<Route render={() => <h1>Page not found</h1>} />
</Switch>
</div>
</Router>
);
