Javascript regular expression single quotes

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

You can use the following regex for example to allow a string like abcd'dfgh:

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

Answer 2

To allow single quote, add it in the character class like ^[a-z A-Z._']{1,15}$

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