如何从包含数组的表单数据以编程方式构建对象

// 获取表单数据
const formData = {
  name: 'John Doe',
  age: 30,
  hobbies: ['reading', 'coding', 'gaming'],
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  }
};

// 解析表单数据并构建对象
function buildObjectFromFormData(formData) {
  const obj = {};

  for (const key in formData) {
    if (Array.isArray(formData[key])) {
      // 数组字段的处理
      obj[key] = [];
      for (let i = 0; i < formData[key].length; i++) {
        obj[key].push(formData[key][i]);
      }
    } else if (typeof formData[key] === 'object') {
      // 对象字段的处理
      obj[key] = buildObjectFromFormData(formData[key]);
    } else {
      // 普通字段的处理
      obj[key] = formData[key];
    }
  }

  return obj;
}

// 使用示例
const result = buildObjectFromFormData(formData);
console.log(result);
