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'
});

不使用findDOMNode

带有ref的类组件

class MyComponent extends Component {
  componentDidMount() {
    this.scrollToBottom();
  }

  componentDidUpdate() {
    this.scrollToBottom();
  }

  scrollToBottom() {
    this.el.scrollIntoView({ behavior: 'smooth' });
  }

  render() {
    return <div ref={el => { this.el = el; }} />
  }
}

带钩子的功能组件:

import React, { useRef, useEffect } from 'react';

const MyComponent = () => {
  const divRef = useRef(null);

  useEffect(() => {
    divRef.current.scrollIntoView({ behavior: 'smooth' });
  });

  return <div ref={divRef} />;
}

谢谢你的回答，但我认为我们可以做得更好， 对于滚动到底部，我们应该使用这个:

scrollToBottom = () => {
   this.messagesEnd.scrollIntoView({ behavior: "smooth", block: "end", inline: "nearest" });
}

但如果你想滚动顶部，你应该使用这个:

scrollToTop = () => {
   this.messagesEnd.scrollIntoView({ behavior: "smooth", block: "start", inline: "nearest" });
}   

这些代码很常见:

componentDidMount() {
  this.scrollToBottom();
}

componentDidUpdate() {
  this.scrollToBottom();
}


render () {
  return (
    <div>
      <div className="MessageContainer" >
        <div className="MessagesList">
          {this.renderMessages()}
        </div>
        <div style={{ float:"left", clear: "both" }}
             ref={(el) => { this.messagesEnd = el; }}>
        </div>
      </div>
    </div>
  );
}

为了向下滚动到页面底部，首先我们必须选择位于页面底部的id。然后我们就可以使用文档了。getElementById选择id并使用scrollIntoView()向下滚动。请参考以下代码。

   scrollToBottom= async ()=>{
      document.getElementById('bottomID').scrollIntoView();
    }

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>
        );
    }
}

这是你在TypeScript中解决这个问题的方法(使用你滚动到的目标元素的ref):

class Chat extends Component <TextChatPropsType, TextChatStateType> {
  private scrollTarget = React.createRef<HTMLDivElement>();
  componentDidMount() {
    this.scrollToBottom();//scroll to bottom on mount
  }

  componentDidUpdate() {
    this.scrollToBottom();//scroll to bottom when new message was added
  }

  scrollToBottom = () => {
    const node: HTMLDivElement | null = this.scrollTarget.current; //get the element via ref

    if (node) { //current ref can be null, so we have to check
        node.scrollIntoView({behavior: 'smooth'}); //scroll to the targeted element
    }
  };

  render <div>
    {message.map((m: Message) => <ChatMessage key={`chat--${m.id}`} message={m}/>}
     <div ref={this.scrollTarget} data-explanation="This is where we scroll to"></div>
   </div>
}
