从JSON数组搜索结果查询中提取动态键值

// 示例JSON数组
const jsonArray = [
  {
    "name": "John",
    "age": 25,
    "city": "New York"
  },
  {
    "name": "Jane",
    "age": 30,
    "city": "San Francisco"
  },
  {
    "name": "Bob",
    "age": 35,
    "city": "Seattle"
  }
];

// 搜索条件
const searchKey = "name";
const searchValue = "Jane";

// 提取动态键值对的函数
function extractKeyValue(jsonArray, searchKey, searchValue) {
  const result = [];
  
  for (let i = 0; i < jsonArray.length; i++) {
    const obj = jsonArray[i];
    
    // 判断当前对象是否匹配搜索条件
    if (obj[searchKey] === searchValue) {
      // 提取匹配的键值对
      const keyValue = {
        key: searchKey,
        value: obj[searchKey]
      };
      
      result.push(keyValue);
    }
  }
  
  return result;
}

// 调用函数并打印结果
const extractedValues = extractKeyValue(jsonArray, searchKey, searchValue);
console.log(extractedValues);
