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>
  )
}

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>

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>
    )
}

我唯一的解决方案是在每个文件中添加一行代码，例如:

import React from 'react';
const file = () => { document.body.scrollTop = 0; return( <div></div> ) }

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>
  )
}

这是我基于其他人在之前的文章中所做的方法。想知道在2020年使用位置作为依赖来防止重渲染是否是一个好方法吗?

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

function ScrollToTop( { children } ) {
    let location = useLocation();

    useEffect( () => {
        window.scrollTo(0, 0);
    }, [ location ] );

    return children
}
