问题描述

我为一个电子邮件字段设置了以下regEx模式，我需要允许连字符（' - '）。这意味着电子邮件字段应允许 - 以及所有其他限制。以下是已定义的正则表达式：

 / ^（（（[az] | \d | [_] | [\ u00A0 -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）+（\（[AZ] |。\d | [_] | [\\\ -\\\퟿\\\豈- \\\﷏\\\ﷰ-\\\￯]）+）*）|（（\x22）（（（（\x20 | \x09）*（\x0d\x0a））？（\x20 | \x09）+）（（[\x01-\x08\x0b\x0c\x0e-\x1f\x7f] |？\x21 | [\x23-\x5b] | [\x5d-\x7e] | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）|（\\（[\x01-\x09\\ \\x0b\x0c\x0d-\x7f] | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]））））*（（（\x20 | \\ \\x09）*（\x0d\x0a））（\x20 |？\x09）+）（\x22）））@（（（[AZ] |？\d | [\\\ - \\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）|（（[AZ] | \d | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\ \￯]）（[AZ] | \d |  -  |。\ | _ |〜| [\u00A 0-\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）*（[AZ] | \d | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ- \\\￯]）））\）+（（[AZ] | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）|（（[AZ] | [ \\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）（[AZ] | \d |  -  |。\ | _ |〜| [\\\ -\\\퟿ \\\豈-\\\﷏\\\ﷰ-\\\￯]）*（[AZ] | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）））\ 。$ $ / i 

我的尝试：



因为这太复杂了，我无法理解并解决这个问题。我试了很多东西，把连字符放在很多地方，但是没有成功。你能帮忙吗？

解决方案

什么我试过了：

它并不复杂，只是讨厌。

要么回到你从那里得到的地方 - 因为如果你写了它你就会知道它是如何工作的 - 或者学习正则表达式并自己修改它。我们不能为你做这件事，因为我们不知道应该在哪里允许' - '而它不在哪里：部分已经明确允许连字符。

这可能会有所帮助：< a href =http://www.ultrapico.com/Expresso.htm> Expresso [ ^ ] - 它是免费的，它检查并生成正则表达式。

我修改了正则表达式模式

 ^（（[[ -  az] | \d | [_] | [\\\00A0-\DD7FF \ uF900-\ uFDCF \ uFDF0-\\ \￯]）+（\（[AZ] |。\d | [_] | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）+）*） |（（\x22）（（（（\x20 | \x09）*（\x0d\x0a））（\x20 |？\x09）+）（（[\x01-\\ \\x08\x0b\x0c\x0e-\x1f\x7f] | \x21 | [\x23-\x5b] | [\x5d-\x7e] | [\\\ -\\ \퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）|（\\（[\x01- \\x09\x0b\x0c\x0d-\x7f] | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]））））*（（（\ X20 | \x09）*（\x0d\x0a））（\x20 |？\x09）+）（\x22）））@（（（[AZ] |？\d | [\\ \ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）|（（[AZ] | \d | [\\\ -\\\퟿\\\豈-\\\﷏\ uFDF0-\\\￯]）（[AZ] | \d |  -  |。\ | _ |〜| [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]） *（[AZ] | \d | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）））\）+（（[AZ] |。[\ u00A0-\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）|（（[AZ] | [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯ ]）（[AZ] | \d |  -  |。\ | _ |〜| [\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）*（[AZ] |。？[\\\ -\\\퟿\\\豈-\\\﷏\\\ﷰ-\\\￯]）））\ 

Hi,

I have the following regEx pattern placed for one Email field, I need to allow hyphen ('-') in the same. That means that the email field should allow '-' along with all the other restrictions. Following is the regex already defined:

/^((([a-z]|\d|[_]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[_]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i

What I have tried:

As this is too complex, i couldn't comprehend and fix this. I tried a lot of stuff, putting hyphen at a lot of places, however didnt succeed. Can you help?

It's not complex, it's just nasty.
Either go back to where you got that from - because if you had written it you'd know how it worked - or learn regexes and modify it yourself. We can't do it for you because we have no idea where it is supposed to allow '-' and where it isn't: parts of that already permit hyphens explicitly.
This may help: Expresso[^] - it's free, and it examines and generates Regular expressions.

I modified regex pattern

^((([-a-z]|\d|[_]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[_]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?
