如何从匹配某个键的JSON对象生成数组？

function generateArrayFromJSON(jsonObj, targetKey) {
  var resultArray = [];
  
  for (var key in jsonObj) {
    if (key === targetKey) {
      resultArray.push(jsonObj[key]);
    } else if (typeof jsonObj[key] === 'object') {
      var subArray = generateArrayFromJSON(jsonObj[key], targetKey);
      resultArray = resultArray.concat(subArray);
    }
  }
  
  return resultArray;
}

// 示例 JSON 对象
var json = {
  "key1": "value1",
  "key2": {
    "key3": "value2",
    "key4": "value3"
  },
  "key5": "value4"
};

var targetKey = "key3";
var result = generateArrayFromJSON(json, targetKey);
console.log(result);
