电子邮件正则表达式验证 javascript
我确实理解验证电子邮件的问题,但我想知道这是否会阻止拥有合法电子邮件的任何人。
我正在寻找有效电子邮件列表来自己测试,但没有找到。
有人拥有有效的电子邮件,但此正则表达式认为它无效吗?
emailRegex.test('[email protected]')
很长的线:
emailRegex = /^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.(([a-z]{2}|AERO|ARPA|ASIA|BIZ|CAT|COM|COOP|EDU|GOV|INFO|INT|JOBS|MIL|MOBI|MUSEUM|NAME|NET|ORG|PRO|TEL|TRAVEL|XN--0ZWM56D|XN--11B5BS3A9AJ6G|XN--3E0B707E|XN--45BRJ9C|XN--80AKHBYKNJ4F|XN--90A3AC|XN--9T4B11YI5A|XN--CLCHC0EA0B2G2A9GCD|XN--DEBA0AD|XN--FIQS8S|XN--FIQZ9S|XN--FPCRJ9C3D|XN--FZC2C9E2C|XN--G6W251D|XN--GECRJ9C|XN--H2BRJ9C|XN--HGBK6AJ7F53BBA|XN--HLCJ6AYA9ESC7A|XN--J6W193G|XN--JXALPDLP|XN--KGBECHTV|XN--KPRW13D|XN--KPRY57D|XN--LGBBAT1AD8J|XN--MGBAAM7A8H|XN--MGBAYH7GPA|XN--MGBBH1A71E|XN--MGBC0A9AZCG|XN--MGBERP4A5D4AR|XN--O3CW4H|XN--OGBPF8FL|XN--P1AI|XN--PGBS0DH|XN--S9BRJ9C|XN--WGBH1C|XN--WGBL6A|XN--XKC2AL3HYE2A|XN--XKC2DL3A5EE0H|XN--YFRO4I67O|XN--YGBI2AMMX|XN--ZCKZAH|XXX)(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)|(^$)/i;
I do understand the problems with validating emails but I wonder whether this would block anyone that has a legal email.
I was looking for a list of valid emails to test it myself but did not find any.
Anyone have an email that is valid but this regex thinks it's not?
emailRegex.test('[email protected]')
Very long line:
emailRegex = /^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.(([a-z]{2}|AERO|ARPA|ASIA|BIZ|CAT|COM|COOP|EDU|GOV|INFO|INT|JOBS|MIL|MOBI|MUSEUM|NAME|NET|ORG|PRO|TEL|TRAVEL|XN--0ZWM56D|XN--11B5BS3A9AJ6G|XN--3E0B707E|XN--45BRJ9C|XN--80AKHBYKNJ4F|XN--90A3AC|XN--9T4B11YI5A|XN--CLCHC0EA0B2G2A9GCD|XN--DEBA0AD|XN--FIQS8S|XN--FIQZ9S|XN--FPCRJ9C3D|XN--FZC2C9E2C|XN--G6W251D|XN--GECRJ9C|XN--H2BRJ9C|XN--HGBK6AJ7F53BBA|XN--HLCJ6AYA9ESC7A|XN--J6W193G|XN--JXALPDLP|XN--KGBECHTV|XN--KPRW13D|XN--KPRY57D|XN--LGBBAT1AD8J|XN--MGBAAM7A8H|XN--MGBAYH7GPA|XN--MGBBH1A71E|XN--MGBC0A9AZCG|XN--MGBERP4A5D4AR|XN--O3CW4H|XN--OGBPF8FL|XN--P1AI|XN--PGBS0DH|XN--S9BRJ9C|XN--WGBH1C|XN--WGBL6A|XN--XKC2AL3HYE2A|XN--XKC2DL3A5EE0H|XN--YFRO4I67O|XN--YGBI2AMMX|XN--ZCKZAH|XXX)(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)|(^$)/i;

Dominic Sayers 创建了一个电子邮件边缘案例列表,您可以使用它来验证您的测试。您可以在此处找到它。
有效地址
test@[IPv6:::]
、"test\ test"@iana.org
或"test@io"
不被你的正则表达式接受。Dominic Sayers has created a list of email edge cases that you could use to validate your test. You can find it here.
The valid address
test@[IPv6:::]
,"test\ test"@iana.org
or"test@io"
are not accepted by your regex.这是一个美丽的表达方式,但很快就会被归入过时的领域:

全球顶级域名 ([email protected])即将到来,他们将在几年内破坏我们所有的脚本:)
不过,要回答你的问题,不,我使用今天对“有效”域名扩展的有限限制,无法破坏您的电子邮件检查。
It's a beautiful expression, but soon to be relegated to the realm of obsolescence:
http://www.icann.org/en/topics/new-gtld-program.htm
Global Top Level Domains ([email protected]) are coming, and they'll break all of our scripts in a few years :)
Though, to answer your question, no, I was not able to break your email check using today's finite limit on "valid" domain extensions.
这是 html 输入字段和按钮字段的代码
现在将以下函数添加到页面的标题
