React-routing -> 即使在“精確”字段之后，路由也會在同一頁面上呈現

Question

我想在登錄頁面中單擊時呈現注冊頁面。 我在路由方面遇到了一些問題。 注冊頁面呈現在同一頁面上。 我只在登錄頁面（“/signup”）上創建了一個路由。 我的目標是僅呈現一個僅包含注冊詳細信息的新頁面。 我認為通過添加精確它會解決它。

 import React from 'react'; import './Login.css'; import {Route, Link, BrowserRouter as Router} from 'react-router-dom' import Signup from "./Signup"; import Home from "./Home"; function Login() { return ( <div class="login-page"> <h2 id="projectName" class="text-center"> login. </h2> <div class="form"> <form class="login-form"> <input type="text" placeholder="Username"/> <input type="password" placeholder="Password"/> <button>login</button> <Router> <p class="message">New user -> <Link to="/signup">Sign up</Link> </p> <Route path="/signup" exact={true} component={Signup} /> </Router> <p class = "message"> <a href="#">Forgot Password</a> or <a href="#">Forgot Username</a> </p> </form> </div> <div class="container"> <div class="row"> <div class="col-lg-12"> <h1 class="tagline text-center"></h1> </div> </div> </div> </div> ); } export default Login;

 import React from 'react'; import './Login.css'; function Signup() { return ( <div class="login-page"> <h2 id="projectName" class="text-center"> signup.</h2> <div class="form"> <form class="login-form"> <input type="text" placeholder="First name"/> <input type="text" placeholder="Last name"/> <input type="email" placeholder="Email"/> <input type="text" placeholder="Username"/> <input type="password" placeholder="Password"/> <button>Sign up</button> <p class="message">Already have an account -> <a href="">Login</a></p> </form> </div> <div class="container"> <div class="row"> <div class="col-lg-12"> <h1 class="tagline text-center"></h1> </div> </div> </div> </div> ); } export default Signup;

頁面在登錄和注冊時的外觀圖像 -> 我只設置了一條路線

Answer 1

通過渲染登錄組件

<Route path="/" exact component={login} />

在 app.js 文件中

希望這能解決你的問題

Answer 2

在 login.js 組件中試試這個

import React from 'react';
import {Link} from 'react-router-dom'

function Login() {
  return (
<div class="login-page">
  <h2 id="projectName" class="text-center"> login. </h2>
  <div class="form">
    <form class="login-form">
      <input type="text" placeholder="Username"/>
      <input type="password" placeholder="Password"/>
      <button>login</button>
            <p class="message">New user ->
            <Link to="/signup">Sign up</Link>
            </p>

      <p class = "message"> <a href="#">Forgot Password</a> or <a href="#">Forgot Username</a> </p>
    </form>
  </div>
  <div class="container">
      <div class="row">
        <div class="col-lg-12">
          <h1 class="tagline text-center"></h1>
        </div>
      </div>
    </div>
</div>

  );
}

export default Login;

在注冊.js

import React from 'react';

function Signup() {
  return (
<div class="login-page">
  <h2 id="projectName" class="text-center"> signup.</h2>
  <div class="form">
    <form class="login-form">
      <input type="text" placeholder="First name"/>
      <input type="text" placeholder="Last name"/>
      <input type="email" placeholder="Email"/>
      <input type="text" placeholder="Username"/>
      <input type="password" placeholder="Password"/>
      <button>Sign up</button>
      <p class="message">Already have an account -> <a href="">Login</a></p>
    </form>
  </div>
  <div class="container">
      <div class="row">
        <div class="col-lg-12">
          <h1 class="tagline text-center"></h1>
        </div>
      </div>
    </div>
</div>


  );
}

export default Signup;

創建路由組件以重定向到其他組件

import React from 'react';
import {Route, Switch} from 'react-router-dom';
import Signup from './Signup'

const Routes = () => {
    return(
      <Switch>
        <Route path="/signup" exact={true} component={Signup} />
      </Switch>
    )
}

export default Routes;
