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>
  );
}

您可以使用引用来跟踪组件。

如果你知道如何设置单个组件的引用(最后一个)，请发布!

以下是我发现对我有用的方法:

class ChatContainer extends React.Component {
  render() {
    const {
      messages
    } = this.props;

    var messageBubbles = messages.map((message, idx) => (
      <MessageBubble
        key={message.id}
        message={message.body}
        ref={(ref) => this['_div' + idx] = ref}
      />
    ));

    return (
      <div>
        {messageBubbles}
      </div>
    );
  }

  componentDidMount() {
    this.handleResize();

    // Scroll to the bottom on initialization
    var len = this.props.messages.length - 1;
    const node = ReactDOM.findDOMNode(this['_div' + len]);
    if (node) {
      node.scrollIntoView();
    }
  }

  componentDidUpdate() {
    // Scroll as new elements come along
    var len = this.props.messages.length - 1;
    const node = ReactDOM.findDOMNode(this['_div' + len]);
    if (node) {
      node.scrollIntoView();
    }
  }
}

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>
  )
}

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>
        );
    }
}

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();
    }
