simple regex for email address validation

Question

I need a regex to exclude certain characters such as 'ç' and also to check '@' sign is present. Can someone help?

I am using jquery to do client-side validation using the following expression:

(/^[\w-]+(\.[\w-]+)*@([\w-]+\.)+[\w-]{2,4}$/)

Answer 1

Chiefly:

function isAValidEmailAddress(emailAddress){
     return /^[a-z0-9_\-\.]{2,}@[a-z0-9_\-\.]{2,}\.[a-z]{2,}$/i.test(emailAddress);
}

Use http://en.wikipedia.org/wiki/Email_address#Syntax for a better regular expression.
