[英]Regex match of email address || a word
I have an input field that will take a keyword input as either an email address or a plain text keyword. 我有一个输入字段,它将关键字输入作为电子邮件地址或纯文本关键字。 I just want to validate that there's no unusual or unsafe characters.
我只想确认没有异常或不安全的字符。 My normal validation expression I use for emails on the webform is:
我在网络表单上用于电子邮件的常规验证表达式是:
"\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"
However, I need an expression that will also take a plain word such as "Blanket". 但是,我需要一个表达式也要使用简单的单词,例如“ Blanket”。 So, I need the expression to take all of the characters of a normal email address but not to validate the sequence that they're in. I've always been horrible at regular expressions.
因此,我需要该表达式接受普通电子邮件地址的所有字符,但不验证它们所在的顺序。正则表达式一直让我感到恐惧。 Thanks for your help, Chris.
克里斯,谢谢您的帮助。
Just do this: 只是这样做:
\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*|\w+

means or . 意味着或 。
So the above regex matches emails or plain words. 因此,上述正则表达式与电子邮件或纯文字匹配。

You shouldn't be trying to validate e-mail addresses using a regexp. 您不应该尝试使用正则表达式来验证电子邮件地址。
The e-mail address format is covered by RFC 5322 and if you where to try and write a regexp that goes close to matching that spec, you would need a regexp that looks something like this: 电子邮件地址格式由RFC 5322涵盖,如果您在哪里尝试编写与该规范相符的正则表达式,则需要一个看起来像这样的正则表达式:
(((?:(?:(?:(?:(?:(?:[\\x20\\x09]*(?:\\x0d\\x0a))?[\\x20\\x09]+)|(?:[\\x20\\x09]+(?:(?:\\x0d\\x0a)[\\x20\\x09]+)* ))?(?:\\x28(?:(?:(?:(?:[\\x20\\x09]*(?:\\x0d\\x0a))?[\\x20\\x09]+)|(?:[\\x20\\x09]+(?:(?:\\x0d\\x0a)[\\x20...(click here to see full regexp) ((((?:(?:(?:(?:(?:(?:[\\ x20 \\ x09] *(?:\\ x0d \\ x0a))?[\\ x20 \\ x09] +)|(? \\ x20 \\ x09] +(?:(?:\\ x0d \\ x0a)[\\ x20 \\ x09] +)*)))?(?:\\ x28(?:(?:(?:(?:[?x20 \\ x09] *(?:\\ x0d \\ x0a))?[\\ x20 \\ x09] +)|(?:[\\ x20 \\ x09] +(?:(?:\\ x0d \\ x0a)[\\ x20 ...(点击此处查看完整的正则表达式)
The easiest way to validate an e-mail address is to send an e-mail to that address. 验证电子邮件地址的最简单方法是将电子邮件发送到该地址。
thanks for the question 谢谢你的问题
