我的申请也遇到了同样的问题。使用下面的代码片段可以帮助我在单击下一个按钮时滚动到页面顶部。

<Router onUpdate={() => window.scrollTo(0, 0)} history= {browserHistory}>
...
</Router>

然而，在浏览器返回时，这个问题仍然存在。经过大量的尝试，我意识到这是因为浏览器窗口的历史对象，它有一个属性scrollRestoration被设置为auto。将此设置为手动解决了我的问题。

function scrollToTop() {
    window.scrollTo(0, 0)
    if ('scrollRestoration' in history) {
        history.scrollRestoration = 'manual';
    }
}

<Router onUpdate= {scrollToTop} history={browserHistory}>
....
</Router>

这有点老套(但很有效):我只是添加

Window. ScrollTo (0, 0);

呈现();

平滑滚动选项

import { useEffect } from 'react';
import { useLocation } from 'react-router-dom';

export default function ScrollToTop() {
  const { pathname } = useLocation();

  useEffect(() => {
    window.scrollTo({
      top: 0,
      left: 0,
      behavior: 'smooth', 
    });
  }, [pathname]);

  return null;
}

...

<Router>
      <ScrollToTop />
     ...
    </Router>

但是课程太2018年了

ScrollToTop实现与React挂钩

ScrollToTop.js

import { useEffect } from 'react';
import { withRouter } from 'react-router-dom';

function ScrollToTop({ history }) {
  useEffect(() => {
    const unlisten = history.listen(() => {
      window.scrollTo(0, 0);
    });
    return () => {
      unlisten();
    }
  }, []);

  return (null);
}

export default withRouter(ScrollToTop);

用法:

<Router>
  <Fragment>
    <ScrollToTop />
    <Switch>
        <Route path="/" exact component={Home} />
    </Switch>
  </Fragment>
</Router>

ScrollToTop也可以实现为一个包装器组件:

ScrollToTop.js

import React, { useEffect, Fragment } from 'react';
import { withRouter } from 'react-router-dom';

function ScrollToTop({ history, children }) {
  useEffect(() => {
    const unlisten = history.listen(() => {
      window.scrollTo(0, 0);
    });
    return () => {
      unlisten();
    }
  }, []);

  return <Fragment>{children}</Fragment>;
}

export default withRouter(ScrollToTop);

用法:

<Router>
  <ScrollToTop>
    <Switch>
        <Route path="/" exact component={Home} />
    </Switch>
  </ScrollToTop>
</Router>

React挂钩2020:)

import React, { useLayoutEffect } from 'react';
import { useLocation } from 'react-router-dom';

const ScrollToTop: React.FC = () => {
  const { pathname } = useLocation();
  useLayoutEffect(() => {
    window.scrollTo(0, 0);
  }, [pathname]);

  return null;
};

export default ScrollToTop;

我在我的项目中使用了Typescript。这招对我很管用:

  // ScrollToTop.tsx
import {useEffect, useRef} from 'react'
import {withRouter} from 'react-router-dom'

const ScrollToTopComponent = () => {
  const mounted = useRef(false)

  useEffect(() => {
    if (!mounted.current) {
      //componentDidMount
      mounted.current = true
    } else {
      //componentDidUpdate
      window.scrollTo(0, 0)
    }
  })

  return null
}

export const ScrollToTop = withRouter(ScrollToTopComponent)



// usage in App.tsx
export default function App() {
  return (
     <Router>
        <ScrollToTop />
        <OtherRoutes />
     </Router>
  )
}
