角度嵌套数组过滤整个对象

function filterObjectByNestedArray(obj, filter) {
  // 遍历对象的属性
  for (let key in obj) {
    // 如果属性值是数组
    if (Array.isArray(obj[key])) {
      // 使用filter方法对数组进行过滤
      obj[key] = obj[key].filter(filter);
    }
    // 如果属性值是对象，则递归调用filterObjectByNestedArray函数
    else if (typeof obj[key] === 'object') {
      obj[key] = filterObjectByNestedArray(obj[key], filter);
    }
  }
  return obj;
}

// 示例数据
const data = {
  name: 'John',
  age: 30,
  hobbies: ['reading', 'coding', 'gaming'],
  address: {
    street: '123 Main St',
    city: 'New York',
    hobbies: ['traveling', 'photography']
  }
};

// 过滤函数，只保留包含字母'o'的元素
const filter = (item) => item.includes('o');

// 调用filterObjectByNestedArray函数进行过滤
const filteredData = filterObjectByNestedArray(data, filter);

console.log(filteredData);
