这是根据RFC 2822(根据此来源)的电子邮件的正确正则表达式:
(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])
除此之外,删除[0]
并添加/g
修饰符,您将获得数组中的完整列表。
如果要将所有数组作为单个字符串获取,请使用以下命令:
var str = arr.join(','); // or whatever delimiter you want to join with
// For example:
['aaa@aaa.com', 'bbb@bbb.net'].join(',') === 'aaa@aaa.com,bbb@bbb.net';
另外,作为一个旁注,在一个著名的 Perl 模块中,这里是用于真正验证 From 和 To 字段中的电子邮件地址的正则表达式(你不感兴趣,但我宁愿在这里有参考,所以我复制粘贴):
