React如何一次自动显示数组中的一个元素

import React, { Component } from 'react';

class ArrayDisplay extends Component {
  constructor(props) {
    super(props);
    this.state = {
      currentIndex: 0, // 当前要显示的数组元素的索引值
    };
  }

  componentDidMount() {
    // 使用定时器每秒更新索引值
    this.interval = setInterval(() => {
      const { currentIndex } = this.state;
      const { array } = this.props;
      const nextIndex = (currentIndex + 1) % array.length; // 循环显示数组元素
      this.setState({ currentIndex: nextIndex });
    }, 1000);
  }

  componentWillUnmount() {
    // 清除定时器
    clearInterval(this.interval);
  }

  render() {
    const { array } = this.props;
    const { currentIndex } = this.state;
    const currentElement = array[currentIndex];

    return (
      <div>
        <p>当前元素：{currentElement}</p>
      </div>
    );
  }
}

export default ArrayDisplay;
