在React中使用表单提交时重定向

npm install react-router-dom

import { BrowserRouter as Router, Route, Redirect } from 'react-router-dom';

import React, { useState } from 'react';
import { useHistory } from 'react-router-dom';

const LoginForm = () => {
  const [username, setUsername] = useState('');
  const [password, setPassword] = useState('');
  const history = useHistory();

  const handleSubmit = (e) => {
    e.preventDefault();
    // 在这里进行表单提交的逻辑处理

    // 重定向到指定页面
    history.push('/dashboard');
  };

  return (
    <form onSubmit={handleSubmit}>
      <input
        type="text"
        value={username}
        onChange={(e) => setUsername(e.target.value)}
        placeholder="Username"
      />
      <input
        type="password"
        value={password}
        onChange={(e) => setPassword(e.target.value)}
        placeholder="Password"
      />
      <button type="submit">Submit</button>
    </form>
  );
};

export default LoginForm;

import React from 'react';
import { BrowserRouter as Router, Route, Redirect } from 'react-router-dom';
import LoginForm from './LoginForm';
import Dashboard from './Dashboard';

const App = () => {
  return (
    <Router>
      <Route exact path="/">
        <Redirect to="/login" />
      </Route>
      <Route path="/login" component={LoginForm} />
      <Route path="/dashboard" component={Dashboard} />
    </Router>
  );
};

export default App;
