Question

我试图用反应路由器做很简单的事情。但我继续遇到错误 - '无法读取属性'推送'未定义'。当我点击测试链接时会发生这种情况。

import { Router, useRouterHistory, Route } from 'react-router';
import { createHashHistory } from 'history';
const appHistory = useRouterHistory(createHashHistory)({ queryKey: false });

ReactDOM.render(React.createElement(nav), document.getElementById('navComponent'));

ReactDOM.render((
    <Router history={appHistory}>
        <Route path="test" component={Test}/>
    </Router>
), document.getElementById('mainContainer'));

nav组件

render() {
        return (
            <div>
              <ul>
               <li><Link to="/test"> Test </Link></li>
              </ul>    
            </div>
        );
    };

测试组件

render() {
        return (
            <div>
              Hello World!   
            </div>
        );
    };

有人可以帮帮我吗？被困在这里。

推送是react-router

的一部分

this.context.router.push(_location);

的package.json

它的作用如下。请比较您的解决方案。基本上最顶层的路线应该具有“/”的路径，对于儿童“/”不是必需的

<Router history={appHistory}>
        <Route path="/" component={Main}>
            <Route path="test" component={Test}/>
            <Route path="*" component={Test}/>
        </Route>
</Router>

const Main = ({children, history}) => {
return (
<div>
<nav>
        <div history={history}/>
      </nav>
      <div>
        {children}
      </div>
</div>
 )
}
