使元素随着React中的延迟而顺序更改

import React, { Component } from 'react';
import './DelayAnimation.css';

class DelayAnimation extends Component {
  constructor(props) {
    super(props);
    this.state = {
      showElements: false
    };
  }

  componentDidMount() {
    setTimeout(() => {
      this.setState({ showElements: true });
    }, 1000); // 设置延迟时间为1秒
  }

  render() {
    const { showElements } = this.state;

    return (
      <div className="container">
        {showElements && (
          <div className="element">Element 1</div>
        )}
        {showElements && (
          <div className="element">Element 2</div>
        )}
        {showElements && (
          <div className="element">Element 3</div>
        )}
      </div>
    );
  }
}

export default DelayAnimation;
