Super simple email validation with javascript

Question

I\'m making a really simple email validation script that basically just checks the following

1. that the email isn\'t blank
2. the the email contains an @ s

Answer 1

Try:

function valid_email(email) {
   return email.match(/^([\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+\.)*[\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+@((((([a-z0-9]{1}[a-z0-9\-]{0,62}[a-z0-9]{1})|[a-z])\.)+[a-z]{2,6})|(\d{1,3}\.){3}\d{1,3}(\:\d{1,5})?)$/i);
}

That is the best available email validation regex, according to this article. I recommend using this, unless your goal is something really simple but not fully compatible.
