在主组件中。

只需添加这个React钩子(如果你没有使用React类):

const oldPage = useRef(pathname)

useEffect(() => {
  if (pathname !== oldPage.current) {
    try {
      window.scroll({
        top: 0,
        left: 0,
        behavior: 'smooth'
      })
    } catch (error) {
      // for older browser
      window.scrollTo(0, 0)
    }
    oldPage.current = pathname
  }
}, [pathname])

对于react-router-dom V5，滚动到顶部

    import React, { useEffect } from 'react';
import {
    BrowserRouter as Router,
    Switch,
    Route,
    Link,
    useLocation,
    withRouter
} from 'react-router-dom'
function _ScrollToTop(props) {
    const { pathname } = useLocation();
    useEffect(() => {
        window.scrollTo(0, 0);
    }, [pathname]);
    return props.children
}
const ScrollToTop = withRouter(_ScrollToTop)
function App() {
    return (
        <div>
            <Router>
                <ScrollToTop>
                    <Header />
                     <Content />
                    <Footer />
                </ScrollToTop>
            </Router>
        </div>
    )
}

钩子是可组合的，从React Router v5.1开始，我们就有了一个useHistory()钩子。所以基于@zurfyx的答案，我为这个功能创建了一个可重用的钩子:

// useScrollTop.ts
import { useHistory } from 'react-router-dom';
import { useEffect } from 'react';

/*
 * Registers a history listener on mount which
 * scrolls to the top of the page on route change
 */
export const useScrollTop = () => {
    const history = useHistory();
    useEffect(() => {
        const unlisten = history.listen(() => {
            window.scrollTo(0, 0);
        });
        return unlisten;
    }, [history]);
};

只需添加这个React钩子(如果你没有使用React类):

const oldPage = useRef(pathname)

useEffect(() => {
  if (pathname !== oldPage.current) {
    try {
      window.scroll({
        top: 0,
        left: 0,
        behavior: 'smooth'
      })
    } catch (error) {
      // for older browser
      window.scrollTo(0, 0)
    }
    oldPage.current = pathname
  }
}, [pathname])

这有点老套(但很有效):我只是添加

Window. ScrollTo (0, 0);

呈现();

对于'REACT-ROUTER-DOM v6及以上'

我通过创建一个包装器函数并将其包装在所有路由上解决了以下问题。

请遵循以下步骤:

1:需要导入以下内容:

import {Routes, Route, BrowserRouter as Router, useLocation} from 'react-router-dom';
import {useLayoutEffect} from 'react';

2:在"App"函数上面写一个包装器函数:

const Wrapper = ({children}) => {
  const location = useLocation();
  useLayoutEffect(() => {
    document.documentElement.scrollTo(0, 0);
  }, [location.pathname]);
  return children
} 

3:现在在包装器函数中包装你的路由:

<BrowserRouter>
  <Wrapper>
    <Navbar />
      <Routes>
        <Route exact path="/" element={<Home/>} />
        <Route path="/Products" element={<Products/>} />
        <Route path="/Login" element={<Login/>} />
        <Route path="/Aggressive" element={<Aggressive/>} />
        <Route path="/Attendance" element={<Attendance/>} />
        <Route path="/Choking" element={<Choking/>} />
        <Route path="/EmptyCounter" element={<EmptyCounter/>} />
        <Route path="/FaceMask" element={<FaceMask/>} />
        <Route path="/Fainting" element={<Fainting/>} />
        <Route path="/Smoking" element={<Smoking/>} />
        <Route path="/SocialDistancing" element={<SocialDistancing/>} />
        <Route path="/Weapon" element={<Weapon/>} />
      </Routes>
    <Footer />
  </Wrapper>
</BrowserRouter>

这应该能解决问题。
