Reactjs:从字符串中的按钮调用函数？

import React from 'react';

class MyComponent extends React.Component {
  handleClick() {
    // 在这里编写按钮点击时的处理逻辑
    console.log('按钮被点击了');
  }

  render() {
    return (
      <div>
        <button onClick={this.handleClick}>按钮</button>
      </div>
    );
  }
}

export default MyComponent;

import React from 'react';
import MyComponent from './MyComponent';

class App extends React.Component {
  render() {
    return (
      <div>
        <h1>我的应用</h1>
        <MyComponent />
      </div>
    );
  }
}

export default App;
