在数组中查找同名的多个键的值

function findValuesByKey(key, array) {
  var values = [];
  
  for (var i = 0; i < array.length; i++) {
    var obj = array[i];
    
    if (obj.hasOwnProperty(key)) {
      values.push(obj[key]);
    }
  }
  
  return values;
}

var array = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Alice', age: 35 },
  { name: 'Charlie', age: 40 }
];

var result = findValuesByKey('name', array);
console.log(result); // 输出: ["Alice", "Alice"]
