在javascript中查找具有公共键的散列数组的最大值

function findMaxValueWithCommonKey(hashArray) {
  var maxValues = {};

  for (var i = 0; i < hashArray.length; i++) {
    var element = hashArray[i];

    for (var key in element) {
      if (maxValues.hasOwnProperty(key)) {
        maxValues[key] = Math.max(maxValues[key], element[key]);
      } else {
        maxValues[key] = element[key];
      }
    }
  }

  var maxKey = null;
  var maxValue = -Infinity;

  for (var key in maxValues) {
    if (maxValues[key] > maxValue) {
      maxValue = maxValues[key];
      maxKey = key;
    }
  }

  return maxKey;
}

// 示例用法
var hashArray = [
  { key1: 10, key2: 20, key3: 30 },
  { key1: 15, key2: 25, key3: 35 },
  { key1: 5, key2: 15, key3: 25 }
];

var maxKey = findMaxValueWithCommonKey(hashArray);
console.log("具有最大值的键是：" + maxKey);
