Javascript正则表达式单引号

Question

My Regex is:

var re = /^[a-z A-Z._]{1,15}$/;

I want to allow this: ' (Single Quote).

How can I do this?

Answer 1

例如，您可以使用以下正则表达式来允许像abcd'dfgh这样的字符串：

/^[A-Za-z\/\']+[A-Za-z]$/

Answer 2

To allow single quote, add it in the character class like ^[az AZ._']{1,15}$

This regex allows ' matching 'abc'_ , a'b'c_ etc.
