我写了一个叫withScrollToTop的高阶组件。这个HOC有两个标志:

onComponentWillMount -导航时是否滚动到顶部(componentWillMount) onComponentDidUpdate—是否在更新时滚动到顶部(componentDidUpdate)。该标志在组件没有卸载但发生导航事件的情况下是必要的，例如，从/users/1到/users/2。

// @flow
import type { Location } from 'react-router-dom';
import type { ComponentType } from 'react';

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

type Props = {
  location: Location,
};

type Options = {
  onComponentWillMount?: boolean,
  onComponentDidUpdate?: boolean,
};

const defaultOptions: Options = {
  onComponentWillMount: true,
  onComponentDidUpdate: true,
};

function scrollToTop() {
  window.scrollTo(0, 0);
}

const withScrollToTop = (WrappedComponent: ComponentType, options: Options = defaultOptions) => {
  return class withScrollToTopComponent extends Component<Props> {
    props: Props;

    componentWillMount() {
      if (options.onComponentWillMount) {
        scrollToTop();
      }
    }

    componentDidUpdate(prevProps: Props) {
      if (options.onComponentDidUpdate &&
        this.props.location.pathname !== prevProps.location.pathname) {
        scrollToTop();
      }
    }

    render() {
      return <WrappedComponent {...this.props} />;
    }
  };
};

export default (WrappedComponent: ComponentType, options?: Options) => {
  return withRouter(withScrollToTop(WrappedComponent, options));
};

使用它:

import withScrollToTop from './withScrollToTop';

function MyComponent() { ... }

export default withScrollToTop(MyComponent);

使用useEffect() -功能组件的解决方案

 useEffect(() => {
window.history.scrollRestoration = 'manual';}, []);

2022年11月更新

在react最新版本18.2.0和react-router-dom 6.4.3中没有任何工作。所以我实现了这个。为我工作。希望这对大家有帮助。

ScrollToTop.js

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

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

  useEffect(() => {
    const body = document.querySelector('#root');
    body.scrollIntoView({
        behavior: 'smooth'
    }, 500)

}, [pathname]);

  return null;
}

然后在index.js或App.js中导入并添加到浏览器路由器，在那里定义路由。

import { BrowserRouter, Routes, Route } from "react-router-dom";
import ScrollToTop from "./ScrollToTop";

function App() {
  return (
    <div>
      <BrowserRouter>
      <ScrollToTop />
        <Routes>
         //your routes
        </Routes>
      </BrowserRouter>
 </div>
  );
}

export default App;

(注意:确保index.html div id="root"。)

    componentWillMount() {
      if (options.onComponentWillMount) {
        scrollToTop();
      }
    }

    componentDidUpdate(prevProps: Props) {
      if (options.onComponentDidUpdate &&

    }
  };
};

  return withRouter(withScrollToTop(WrappedComponent, options));
};

import withScrollToTop from './withScrollToTop';

function MyComponent() { ... }

export default withScrollToTop(MyComponent);

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>

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>
