如何使用动态过滤器过滤javascript对象

function dynamicFilter(arr, condition) {
  return arr.filter(item => {
    for (let key in condition) {
      if (item[key] !== condition[key]) {
        return false;
      }
    }
    return true;
  });
}

const people = [
  { name: 'Alice', age: 20 },
  { name: 'Bob', age: 17 },
  { name: 'Charlie', age: 22 }
];

const filteredPeople = dynamicFilter(people, { age: 18 });
console.log(filteredPeople);
// 输出: [ { name: 'Alice', age: 20 }, { name: 'Charlie', age: 22 } ]

// 错误的属性名
const filteredPeople = dynamicFilter(people, { Age: 18 }); // 注意Age是大写

// 正确的属性名
const filteredPeople = dynamicFilter(people, { age: 18 }); // age是小写

function dynamicFilter(arr, condition) {
  return arr.filter(item => {
    for (let key in condition) {
      if (typeof condition[key] === 'object') {
        if (!deepMatch(item[key], condition[key])) {
          return false;
        }
      } else {
        if (item[key] !== condition[key]) {
          return false;
        }
      }
    }
    return true;
  });
}

function deepMatch(obj1, obj2) {
  for (let key in obj2) {
    if (obj1[key] !== obj2[key]) {
      return false;
    }
  }
  return true;
}

const people = [
  { name: 'Alice', age: 20, details: { city: 'New York' } },
  { name: 'Bob', age: 17, details: { city: 'Los Angeles' } }
];

const filteredPeople = dynamicFilter(people, { age: 20, details: { city: 'New York' } });
console.log(filteredPeople);
// 输出: [ { name: 'Alice', age: 20, details: { city: 'New York' } } ]
