// this.props.history.push(path);
// antd ts react 界面跳转
};

</AutoComplete>
</div>
);
}
}

报错
pment.js:16227 Uncaught Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.

不知道你这个问题是否已经解决, 如果还没有解决的话: <Button type="primary" style={{ float:"right", display : repair["state"] == '2' ? 'inline': 'none'}} >
<Link to={{pathname:"/RepairProcessing/RepairRequest",query:{serviceUuid:repair["serviceUuid"]}}} >
查看详情
</Link>
</Button>
通过<Link to={{pathname:"路径名",query:{键名:键值}}}文本内容 </Link>
进行传值以及页面跳转 ,接收页面通过
const RepairRequest:FC<UserPageProps> =({RepairProcessing,dispatch,userListLoading, location: { query: { serviceUuid }}})=>{
const RepairRequest:FC<UserPageProps> =({RepairProcessing,dispatch,userListLoading, location: { query: { serviceUuid }}})=>{
通过location{query:{键名}}就可取到值。
回答: 在使用任何编程语言或框架时,都可能出现报错。可能有以下几种情况:
语法错误:代码中存在语法错误,导致程序无法正确运行。
代码逻辑错误:代码逻辑有误,也可能会导致程序无法正确运行。
环境问题:代码运行的环境有误,例如缺乏必要的依赖库或配置错误等等。
当出现报错时,错误信息通常会被显示在控制台或日志中。具体的报错信息有可能涉及到哪部分代码或者哪个文件出现了问题。
对于 React 开发 Web 应用时的页面跳转问题,可以使用 React Router 来实现。下面是一个简单的例子:
npm install react-router-dom
import React from 'react';
import { BrowserRouter, Route } from 'react-router-dom';
import Home from './pages/Home';
import About from './pages/About';
function App() {
return (
<BrowserRouter>
<Route path="/" exact component={Home} />
<Route path="/about" component={About} />
</BrowserRouter>
);
}
export default App;
// Home.js
import React from 'react';
function Home() {
return <h1>Home Page</h1>;
}
export default Home;
// About.js
import React from 'react';
function About() {
return <h1>About Page</h1>;
}
export default About;
import React from 'react';
import { Link } from 'react-router-dom';
function NavBar() {
return (
<ul>
<li><Link to="/">Home</Link></li>
<li><Link to="/about">About</Link></li>
</ul>
);
}
export default NavBar;
通过以上步骤,就可以实现简单的页面跳转。当用户点击导航栏中的链接时,React Router 会根据路径匹配对应的组件并渲染到页面上。如果路径没有匹配到任何组件,则会显示默认的 404 页面。
