I have set up email validation for a Select2 list with help of a regular expression.

It should only accept emails that have a pattern like [email protected] (alt [email protected]). The validation works for the domains but the validation for fn+ln doesn’t work, it accepts entries like [email protected] which it shouldn’t.

What am I doing wrong?

Here is my set up:

$(document).ready(function() {
    var noResults = '#{javascript: return utilityBean.escapeJS(xptI18NBean.getValue("strings.gen_enter_email"))}';
    x$("#{id:select2Example}").select2({
        dropdownAutoWidth: true,
        width: 'resolve',
        allowClear: true,
        createTag: function(term, data) {
            var value = term.term;
            if (validateEmail(value)) {
                return {
                    id: value,
                    text: value
                };
            } else {
                //not valide yet?
            }
            return null;
        },
        "language": {
            "noResults": function() {
                return noResults;
            }
        }
    });
});

function validateEmail(email) {
    var regex_email = /^(([w-]+(?:.[w-]+)*)@(acme.org|acme.com))$/;
    return regex_email.test(email);
}
