如何在状态转换前暂停组件的延迟？

import React, { Component } from 'react';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: '',
      shouldUpdate: true
    };
  }

  componentDidMount() {
    // 模拟延迟获取数据
    setTimeout(() => {
      this.setState({ data: 'Hello World' });
    }, 2000);
  }

  shouldComponentUpdate(nextProps, nextState) {
    // 在状态转换前暂停组件的延迟
    return this.state.shouldUpdate;
  }

  render() {
    return (
      <div>
        <h1>{this.state.data}</h1>
        <button onClick={() => this.setState({ shouldUpdate: false })}>
          暂停延迟
        </button>
      </div>
    );
  }
}

export default MyComponent;
