你可以使用React路由器dom v4

创建一个scrollToTopComponent组件，如下所示

class ScrollToTop extends Component {
    componentDidUpdate(prevProps) {
      if (this.props.location !== prevProps.location) {
        window.scrollTo(0, 0)
      }
    }

    render() {
      return this.props.children
    }
}

export default withRouter(ScrollToTop)

或者如果你正在使用标签使用类似下面的东西

class ScrollToTopOnMount extends Component {
    componentDidMount() {
      window.scrollTo(0, 0)
    }

    render() {
      return null
    }
}

class LongContent extends Component {
    render() {
      <div>
         <ScrollToTopOnMount/>
         <h1>Here is my long content page</h1>
      </div>
    }
}

// somewhere else
<Route path="/long-content" component={LongContent}/>

希望这有助于更多关于滚动恢复访问docs hare react路由器dom滚动恢复

这个答案只适用于v4版本，而不适用于后续版本。

React Router v4的文档包含了用于滚动恢复的代码示例。下面是他们的第一个代码示例，它作为一个全站解决方案，当页面导航到“滚动到顶部”:

class ScrollToTop extends Component {
  componentDidUpdate(prevProps) {
    if (this.props.location !== prevProps.location) {
      window.scrollTo(0, 0)
    }
  }

  render() {
    return this.props.children
  }
}

export default withRouter(ScrollToTop)

然后在你的应用程序的顶部渲染它，但在路由器下面:

const App = () => (
  <Router>
    <ScrollToTop>
      <App/>
    </ScrollToTop>
  </Router>
)

// or just render it bare anywhere you want, but just one :)
<ScrollToTop/>

^直接从文档中复制

显然，这适用于大多数情况，但是关于如何处理选项卡接口以及为什么没有实现通用解决方案还有更多内容。

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';}, []);

在router.js中，只需在router对象中添加这个函数。这个就行了。

scrollBehavior() {
        document.getElementById('app').scrollIntoView();
    },

像这样,

* * Routes.js * *

import vue from 'blah!'
import Router from 'blah!'

let router = new Router({
    mode: 'history',
    base: process.env.BASE_URL,
    scrollBehavior() {
        document.getElementById('app').scrollIntoView();
    },
    routes: [
            { url: "Solar System" },
            { url: "Milky Way" },
            { url: "Galaxy" },
    ]
});

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>
