[jQuery] Form Validation

[jQuery] Form Validation


I have just started using jQuery and wonder if you could help me
please.
I am working on a form which contains a field to enter multi-email
addresses. How could I validate this field using jQuery?
This is what I would do if I were not using the jQuery library
function multiEmail(my_emails) {
    var email = my_emails.split(';');
    for (var i = 0; i < email.length; i++) {
    if (!validateEmail(email[i], "Your email is invalid.", 0)) {
    return false;
    }
    }
    return true;
    }
function validateEmail(email, msg) {....}
How could I customize the function above to go inside the addMethod
below?
jQuery.validator.addMethod("multiEmail", function(...) {
}
