是否可以在javascript中的同一查询中返回具有JSON路径的子节点和父节点

function findNodeWithParent(json, path) {
  const result = {
    parent: null,
    child: null
  };

  function traverse(obj, parentPath) {
    for (let key in obj) {
      const currentPath = parentPath ? `${parentPath}.${key}` : key;
      if (currentPath === path) {
        result.parent = obj;
        result.child = obj[key];
        return;
      }
      if (typeof obj[key] === 'object') {
        traverse(obj[key], currentPath);
      }
    }
  }

  traverse(json, '');

  return result;
}

// 示例用法
const json = {
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  }
};

const result = findNodeWithParent(json, 'address.city');
console.log(result.parent); // 输出：{ "street": "123 Main St", "city": "New York" }
console.log(result.child); // 输出："New York"
