我喜欢这样做。

componentDidUpdate(prevProps, prevState){
  this.scrollToBottom();
}

scrollToBottom() {
  const {thing} = this.refs;
  thing.scrollTop = thing.scrollHeight - thing.clientHeight;
}

render(){
  return(
    <div ref={`thing`}>
      <ManyThings things={}>
    </div>
  )
}

另一个值得考虑的选择是react scroll组件。

在上面的答案中，scrollIntoView(…)方法有两个主要问题:

it's semantically incorrect, as it causes the entire page to scroll if your parent element is scrolled outside the window boundaries. The browser literally scrolls anything it needs to in getting the element visible. in a functional component using useEffect(), you get unreliable results, at least in Chrome 96.0.4665.45. useEffect() gets called too soon on page reload and the scroll doesn't happen. Delaying scrollIntoView with setTimeout(..., 0) fixes it for page reload, but not first load in a fresh tab, at least for me. shrugs

这是我一直在使用的解决方案，它很可靠，而且更兼容旧的浏览器:

function Chat() {
   const chatParent = useRef<HTMLDivElement(null);

   useEffect(() => {
      const domNode = chatParent.current;
      if (domNode) {
         domNode.scrollTop = domNode.scrollHeight;
      }
   })
   return (
      <div ref={chatParent}>
         ...
      </div>
   )
}

我在mweb/web中遇到过这个问题。所有的解决方案是很好的在这个页面，但所有的解决方案是不工作，而使用android chrome浏览器。 所以对于mweb和web，我得到了一些小的解决方案。

    import { createRef, useEffect } from 'react';
    import { useSelector } from 'react-redux';
    import { AppState } from 'redux/store';
    import Message from '../Message/Message';
    import styles from './MessageList.module.scss';
    
    const MessageList = () => {
      const messagesEndRef: any = createRef();
      const { messages } = useSelector((state: AppState) => state?.video);
      const scrollToBottom = () => {
          //this is not working in mWeb
            // messagesEndRef.current.scrollIntoView({
            //   behavior: 'smooth',
            //   block: 'end',
            //   inline: 'nearest',
            // });
         const scroll =
          messagesEndRef.current.scrollHeight -
           messagesEndRef.current.clientHeight;
         messagesEndRef.current.scrollTo(0, scroll);
      };
    
      useEffect(() => {
        if (messages.length > 3) {
          scrollToBottom();
        }
      }, [messages]);
    
      return (
        <section className={styles.footerTopSection} ref={messagesEndRef} >
          {messages?.map((message: any) => (
            <Message  key={message.id} {...message} />
          ))}
        </section>
      );
    };
    
    export default MessageList;

如果用户已经在可滚动部分的底部，react- scrolable -feed会自动向下滚动到最新的元素。否则，它将使用户处于相同的位置。我认为这对聊天组件非常有用:)

我认为这里的其他答案将强制每次滚动，无论滚动条在哪里。scrollIntoView的另一个问题是，如果您的可滚动div不在视图中，它将滚动整个页面。

它可以这样使用:

import * as React from 'react'

import ScrollableFeed from 'react-scrollable-feed'

class App extends React.Component {
  render() {
    const messages = ['Item 1', 'Item 2'];

    return (
      <ScrollableFeed>
        {messages.map((message, i) => <div key={i}>{message}</div>)}
      </ScrollableFeed>
    );
  }
}

只要确保包装器组件具有特定的高度或max-height即可

免责声明:我是包裹的所有者

我不能得到以下任何答案的工作，但简单的js为我做的伎俩:

  window.scrollTo({
  top: document.body.scrollHeight,
  left: 0,
  behavior: 'smooth'
});
