允许（+）登录电子邮件验证 [英] Allow (+) sign in email validation

问题描述

我正在使用正则表达式来验证电子邮件。



/^([\w-]+(?:。[\\\-] + ））@（（？：[\w - ] +）\w [\w - ] {0,66}）（[AZ] {2,6-}（：[AZ] {2。？。 }）（\。+ \）？）$ / i



所以我想允许+号只允许其他特殊字符。



我需要在这种模式下做出什么改变？



谢谢Anubhav

I am using the regular expression to validate emails.

/^([\w-]+(?:.[\w-]+))@((?:[\w-]+.)\w[\w-]{0,66}).([a-z]{2,6}(?:.[a-z]{2})(\".+\")?)$/i

So i want to allow the + sign only other special characters are not allowed.

What change I need to make in this pattern?

Thanks Anubhav

I不知道你想要实现什么以及为什么，但是'+'是正则表达式语法的一部分，所以我能看到的唯一可能的问题是知道你可以转义任何字符，在这种情况下，'\ + 。我没有在你的Regex示例中看到这两个字符的组合，这让我觉得这是你的问题。

I don't know what do you want to achieve and why, but '+' is a part of Regular Expression syntax, so the only possible problem I can see is knowing that you can escape any character, in this case, '\+'. I did not see this combination of two characters in your Regex sample, that makes me think that this is your problem.
