在JSON对象中递归搜索属性名称{String}并返回关联值

function searchPropertyValue(obj, propertyName) {
  let results = [];

  function search(obj) {
    for (let key in obj) {
      if (typeof obj[key] === 'object' && obj[key] !== null) {
        // 递归搜索对象属性
        search(obj[key]);
      } else if (key === propertyName) {
        // 找到匹配的属性名称
        results.push(obj[key]);
      }
    }
  }

  search(obj);

  return results;
}

// 示例JSON对象
const json = {
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  },
  "phones": [
    {
      "type": "home",
      "number": "555-1234"
    },
    {
      "type": "work",
      "number": "555-5678"
    }
  ]
};

// 搜索属性名为"type"的关联值
const results = searchPropertyValue(json, "type");
console.log(results); // 输出: ["home", "work"]
