I have this RegExp:
var reg = new RegExp("^[0-9a-zA-Z]+@[0-9a-zA-Z]+[\.]{1}[0-9a-zA-Z]+[\.]?[0-9a-zA-Z]+$");

Open in new window


But  i need to allow email addresses like some.guy@gmail.com

Right now this kind of email is rejected.  I'm guessing _ would also be rejected.

Any ideas on what I need to change?  I was thinking:
var reg = new RegExp("^[0-9a-zA-Z.]+@[0-9a-zA-Z]+[\.]{1}[0-9a-zA-Z]+[\.]?[0-9a-zA-Z]+$");

but i don't want to take down the contact form if i'm wrong.

Thanks for your help!!!

Your change would work for your stated purpose,
although it will still reject valid email addresses such as
The Fred and Barney Comedy Team <fred&barney@stonehenge.com>

By the way the \ and {1} in your expression are unnecessary

If you'd like to match the regex used by HTML5, I did a video tutorial on why you might like to use it: http://www.experts-exchange.com/Programming/Languages/Scripting/PHP/VP_245.html

The pattern is:
^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$

That still rejects some valid email addresses, although addresses with quoted strings, comments, and Unicode may be less common.
