通过标签重构嵌套的JSON数据- Javascript

function reconstructJSON(jsonData, tag) {
  if (typeof jsonData === 'object') {
    if (Array.isArray(jsonData)) {
      return jsonData.map(item => reconstructJSON(item, tag));
    } else {
      const reconstructedData = {};
      Object.keys(jsonData).forEach(key => {
        if (key === tag) {
          return jsonData[key];
        }
        reconstructedData[key] = reconstructJSON(jsonData[key], tag);
      });
      return reconstructedData;
    }
  } else {
    return jsonData;
  }
}

// 示例用法
const jsonData = {
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "country": "USA"
  },
  "tags": ["tag1", "tag2", "tag3"]
};

const reconstructedData = reconstructJSON(jsonData, "address");
console.log(reconstructedData);
