Solution 1

You're not including hyphen characters in the domain name section of your reg-ex. Suggest the following to include them:

/^[^\\W][a-zA-Z0-9\\_\\-\\.]+([a-zA-Z0-9\\_\\-\\.]+)*\\@[a-zA-Z0-9_\\-]+(\\.[a-zA-Z0-9_\\-]+)*\\.[a-zA-Z]{2,4}$/

I have find a solution to my problem by changing my expression to this:

JavaScript

<pre lang="xml"><script type="text/javascript">
            jQuery(function(){
                jQuery("#email").validate({

                    expression: "if (VAL.match(/^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/)) return true; else return false;",
                    message: "<br>Please provide a valid email address!!</b>"

                });
            });
