Error in email authentication regular expression

I am trying to validate my client side email address field using jQuery and regex, but for some reason javaScript is complaining about a syntax error in regex as

@((?:[\w-]+\.)*\w[\w-]{0,66})

of

/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i;

JQuery function

$('.emailField').change(function () {

    var inputVal = $(this).val();

    var emailReg = /^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i;

    if (!emailReg.test(inputVal)) {

        $(this).after('<span class="error error-keyup-7">Invalid Email Format.</span>');
    }

});

I have a separate plugin for this and it gets called on my partial view and it worked!



(function ($) {

   $.fn.validateEmail = function (_email) {

      alert(_email);

      var re = /^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i;

      return re.test(_email);
   };

}(jQuery));

var emailReg = new RegExp(/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i);
if (!emailReg.test(inputVal)) {
