如何从对象数组中检索电子邮件字段？

// 示例对象数组
var objects = [
  { name: 'John Doe', email: 'john@example.com', age: 30 },
  { name: 'Jane Smith', email: 'jane@example.com', age: 25 },
  { name: 'Bob Johnson', email: 'bob@example.com', age: 35 },
  { name: 'Alice Williams', email: 'alice@example.com', age: 28 }
];

// 存储电子邮件字段的数组
var emails = [];

// 遍历对象数组并检索电子邮件字段
for (var i = 0; i < objects.length; i++) {
  var object = objects[i];
  if (typeof object.email === 'string' && object.email.includes('@')) {
    emails.push(object.email);
  }
}

// 输出电子邮件字段
console.log(emails);
