如何在`this.state`对象中获取状态值

this.state.counter

import React, { Component } from 'react';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      counter: 0
    };
  }

  handleClick() {
    // 获取状态值
    const counterValue = this.state.counter;
    console.log(counterValue);
  }

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

export default MyComponent;
