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;

这对我很有用

messagesEndRef.current.scrollTop = messagesEndRef.current.scrollHeight

const messagesEndRef = useRef();使用

import React, {Component} from 'react';

export default class ChatOutPut extends Component {

    constructor(props) {
        super(props);
        this.state = {
            messages: props.chatmessages
        };
    }
    componentDidUpdate = (previousProps, previousState) => {
        if (this.refs.chatoutput != null) {
            this.refs.chatoutput.scrollTop = this.refs.chatoutput.scrollHeight;
        }
    }
    renderMessage(data) {
        return (
            <div key={data.key}>
                {data.message}
            </div>
        );
    }
    render() {
        return (
            <div ref='chatoutput' className={classes.chatoutputcontainer}>
                {this.state.messages.map(this.renderMessage, this)}
            </div>
        );
    }
}

完整版(Typescript):

import * as React from React 导出类DivWithScrollHere扩展React。组件<any, any> { loading:any = React.createRef(); componentDidMount () { this.loading.scrollIntoView(假); } 呈现(){ 回报( <div ref={e =>{这个。装载= e;}}> <LoadingTile /> </div> . txt ） } }

这是根据上面的答案修改的，以支持“children”而不是数据数组。

注意:样式化组件的使用对于解决方案并不重要。

import {useEffect, useRef} from "react";
import React from "react";
import styled from "styled-components";

export interface Props {
    children: Array<any> | any,
}

export function AutoScrollList(props: Props) {
    const bottomRef: any = useRef();

    const scrollToBottom = () => {
        bottomRef.current.scrollIntoView({
            behavior: "smooth",
            block: "start",
        });
    };

    useEffect(() => {
        scrollToBottom()
    }, [props.children])

    return (
        <Container {...props}>
            <div key={'child'}>{props.children}</div>
            <div key={'dummy'} ref={bottomRef}/>
        </Container>
    );
}

const Container = styled.div``;

Reference your messages container. <div ref={(el) => { this.messagesContainer = el; }}> YOUR MESSAGES </div> Find your messages container and make its scrollTop attribute equal scrollHeight: scrollToBottom = () => { const messagesContainer = ReactDOM.findDOMNode(this.messagesContainer); messagesContainer.scrollTop = messagesContainer.scrollHeight; }; Evoke above method on componentDidMount and componentDidUpdate. componentDidMount() { this.scrollToBottom(); } componentDidUpdate() { this.scrollToBottom(); }

这是我如何在我的代码中使用这个:

 export default class StoryView extends Component {

    constructor(props) {
        super(props);
        this.scrollToBottom = this.scrollToBottom.bind(this);
    }

    scrollToBottom = () => {
        const messagesContainer = ReactDOM.findDOMNode(this.messagesContainer);
        messagesContainer.scrollTop = messagesContainer.scrollHeight;
    };

    componentDidMount() {
        this.scrollToBottom();
    }

    componentDidUpdate() {
        this.scrollToBottom();
    }

    render() {
        return (
            <div>
                <Grid className="storyView">
                    <Row>
                        <div className="codeView">
                            <Col md={8} mdOffset={2}>
                                <div ref={(el) => { this.messagesContainer = el; }} 
                                     className="chat">
                                    {
                                        this.props.messages.map(function (message, i) {
                                            return (
                                                <div key={i}>
                                                    <div className="bubble" >
                                                        {message.body}
                                                    </div>
                                                </div>
                                            );
                                        }, this)
                                    }
                                </div>
                            </Col>
                        </div>
                    </Row>
                </Grid>
            </div>
        );
    }
}
