JQ:根据对象名称从嵌套数组中的对象中提取值

function getValueFromNestedArray(arr, target) {
  for (let i = 0; i < arr.length; i++) {
    const current = arr[i];
    if (typeof current === 'object') {
      if (current.hasOwnProperty(target)) {
        return current[target];
      }
      if (Array.isArray(current) && current.length > 0) {
        const result = getValueFromNestedArray(current, target);
        if (result !== undefined) {
          return result;
        }
      }
    }
  }
}

// 示例数据
const data = [
  {
    name: 'Alice',
    age: 25,
    hobbies: ['reading', 'painting'],
    address: {
      street: '123 Main St',
      city: 'New York',
      country: 'USA'
    }
  },
  {
    name: 'Bob',
    age: 30,
    hobbies: ['coding', 'gaming'],
    address: {
      street: '456 Elm St',
      city: 'San Francisco',
      country: 'USA'
    }
  }
];

// 从示例数据中提取值
const name = getValueFromNestedArray(data, 'name');
console.log(name); // 输出: 'Alice'

const street = getValueFromNestedArray(data, 'street');
console.log(street); // 输出: '123 Main St'

const hobbies = getValueFromNestedArray(data, 'hobbies');
console.log(hobbies); // 输出: ['reading', 'painting']

const country = getValueFromNestedArray(data, 'country');
console.log(country); // 输出: 'USA'
