reactjs - 在 React 中获取路由中的错误

Question

我的路由出现异常问题。我有一个主页，然后在主页的中层，我有一个关于页面的链接。当我单击它时，会将我重定向到关于页面的中间级别。为什么它没有把我带到关于页面的顶层。我想我已经在主页滚动，因为它也在关于页面中滚动我不知道这是一个非常奇怪的问题。我在这里提供我的导航项目和我所有的链接代码。如果可以的话，请给我一个解决方案。

将此添加到您的 App 组件中：

const location = useLocation();
 
useLayoutEffect(() => {
    window.scrollTo(0, 0);
}, [location.pathname]);
