如何在react中添加动态表单的按钮点击？

import React, { Component } from 'react';

class DynamicForm extends Component {
  constructor(props) {
    super(props);
    this.state = {
      formData: [], // 存储动态表单数据的数组
    };
  }

  handleAddForm = () => {
    // 点击按钮时添加新的表单数据
    const newForm = {
      // 表单数据的属性
    };
    this.setState(prevState => ({
      formData: [...prevState.formData, newForm],
    }));
  };

  handleChange = (index, event) => {
    // 更新表单数据
    const { name, value } = event.target;
    this.setState(prevState => {
      const formData = [...prevState.formData];
      formData[index][name] = value;
      return { formData };
    });
  };

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

    return (
      <div>
        {formData.map((form, index) => (
          <div key={index}>
            {/* 渲染动态表单的内容 */}
            <input
              type="text"
              name="fieldName"
              value={form.fieldName}
              onChange={event => this.handleChange(index, event)}
            />
          </div>
        ))}
        <button onClick={this.handleAddForm}>添加表单</button>
      </div>
    );
  }
}

export default DynamicForm;
