react-router 在每次转换时滚动到顶部 [英] react-router scroll to top on every transition

问题描述

我在导航到另一个页面时遇到问题，它的位置将保持与之前的页面一样.所以它不会自动滚动到顶部.我还尝试在 onChange 路由器上使用 window.scrollTo(0, 0) .我也使用 scrollBehavior 来解决这个问题，但它没有用.对此有什么建议吗?

I have an issue when navigating into another page, its position will remain like the page before. So it won't scroll to top automatically. I've also tried to use window.scrollTo(0, 0) on onChange router. I've also used scrollBehavior to fix this issue but it didn't work. Any suggestions about this?

推荐答案

2018 年的课程就是这样

ScrollToTop.js

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 也可以实现为包装组件:

ScrollToTop can also be implemented as a wrapper component:

ScrollToTop.js

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>
