Validating email in javascript

Question

var emailRegex =/^(?("")(""[^""]+?""@)|(([0-9a-z]((\.(?!\.))|[-!#\$%&'\*\+/=\?\^`\{\}\|~\w])*)
(?<=[0-9a-z])@))(?(\[)(\[(\d{1,3}\.){3}\d{1,3}\])|(([0-9a-z][-\w]*[0-9a-z]*\.)+[a-z0-9]{2,24}))$/

above pattern for email validations giving Error:

")" is not valid at the start of a code block. 
 Only identifiers, keywords, comments, "(" and "{" are valid.

@Degnome it's working fine in jsbin but in Visual Studio it is giving error Error: Unexpected character '\' — user3131488, Dec 24 '13 at 05:38

Using regular expressions is probably the best way.

function validate(email) { 
var emailPattern = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;  
if (emailPattern.test(email.value) == false) 
    {
        alert('Invalid Email Address');
        return false;
    }

    return true;
}

This should be validated on the server side as well.
