<p>我無法找到此問題的任何解決方案。 </p>
<p>這些是我在文件中使用的程式碼。app.js程式碼：</p>
<pre class="brush:php;toolbar:false;">從 './logo.svg' 匯入標誌；
導入'./App.css';
從 './components/LoginForm' 導入 LoginForm；
從“./signup”匯入註冊；
從 'react-router-dom' 導入 { BrowserRouter as Router, Routes, Route, Link, useNavigate };
函數應用程式（）{
常量導航 = useNavigate();
const handleSignUpClick = () =>; {
導航('/註冊');
}
返回 （
<路由器>
<a className=“nav-link active” aria-current=“頁” href=“#” onClick={handleSignUpClick}>
報名
</a>
</h3>
<路線>
<路由路徑=“/” element={} />;
<路由路徑=“/signup”元素={<註冊/>} />
</路線>
</路由器>
）；
}
導出預設應用程式；</pre>
<p>這是LoginForm.js的程式碼：</p>
從 'react' 匯入 React, { useState };
從 'reactstrap' 匯入 { 按鈕、表單、FormGroup、標籤、輸入、InputGroup }；
從 'react-icons/fa' 導入 { FaEye, FaEyeSlash };
函數登入表單（）{
const [用戶名，setUsername] = useState('');
const [密碼，setPassword] = useState('');
const [showPassword, setShowPassword] = useState(false);
const handleSubmit = (事件) =>; {
//處理提交
}
consttoggleShowPassword = () =>; {
setShowPassword(!showPassword);
}
返回 （
<表單onSubmit={handleSubmit}>
<表單組>
<標籤=「使用者名稱」>使用者名稱
<輸入類型=“文字” name="用戶名" id="用戶名" value={使用者名稱} onChange={e =>; setUsername(e.target.value)} //>
</表單組>
<表單組>
<用於=「密碼」的標籤>密碼
<輸入群組>
<輸入類型={showPassword ? '文本' : '密碼'} name=“密碼” id=“密碼” value={password} onChange={e =>; setPassword(e.target.value)} //>
<按鈕onClick={toggleShowPassword}>
{顯示密碼 ？
> :
}
</按鈕>
</輸入組>
</表單組>
<按鈕>提交
</表格>
import './App.css';
函數註冊（）{
返回 （
<h1>應用</h1>
）；
}
匯出預設註冊；</pre></p>
