Jeg har flg. kode, den virker fint m.h.t. databaseforespørgsel, men jeg kan ikke få den til at validere emailen :-(....

Hvad gør jeg lige forkert ?


function isValidEmailAddress(emailAddress) {
    var pattern = /^([a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+(\.[a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+)*|"((([ \t]*\r\n)?[ \t]+)?([\x01-\x08\x0b\x0c\x0e-\x1f\x7f\x21\x23-\x5b\x5d-\x7e\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|\\[\x01-\x09\x0b\x0c\x0d-\x7f\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))*(([ \t]*\r\n)?[ \t]+)?")@(([a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.)+([a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.?$/i;
    return pattern.test(emailAddress);
};

$(document).ready(function() {
    $("#email").keyup(function (e) {

var email = $(this).val();
if( isValidEmailAddress( email ) ) { $("#email-result").html(' det er sku OK!!'); }


  if(email.length < 6){
    $("#email-result").html(' er for kort');
    $("#join_button").attr("disabled", true);
  return;
}


    if(email.length >= 6){

            $("#email-result").html('');
            $.post('Webshop/username-checker.php', {'email':email}, function(data) {

            if(data == '1'){
            $("#submit").attr("disabled", false);
            $("#join_button").attr("disabled", false);
            $("#email-result").html(' er Ledigt');
            $('#email').css('border', '3px #2ecc71 solid');

            }else{
                $("#submit").attr("disabled", true);
                $("#join_button").attr("disabled", true);
                $("#email-result").html(' er optaget!');
                $('#email').css('border', '3px #c0392b solid');
            }
            });
          }  });
      });
