注册按钮不允许我导航到注册组件
输出:注册按钮应该允许我重定向
我试图遵循指南并查找示例实现,但无法解决问题。只有
呈现
和直接从呈现
函数调用的函数应该返回JSX,因为这些函数呈现UI
当你考虑诸如<代码>登录名为“/COD>函数”时,该函数将响应于单击的按钮而被调用。在这里,您应该添加命令代码,将用户重定向到
/redirect
页面。但是在调用此函数之前,应该设置重定向的路由
,以便React Router知道要渲染哪个组件
你的整个应用程序(通常)需要一个单一的代码>路由器组件,你的整个应用程序都被封装进去了,在你的例子中,考虑一下:
import { BrowserRouter as Router } from "react-router-dom";
ReactDOM.render(<Router>
<Route path="/Register" component={Register} />
<Route exact path="/" component={App />
</Router>, document.getElementById("root") />
这里有很多假设,我确实认为在开始之前,您需要检查并更好地理解路由。只有
