Endless background color animation in jQuery, how?

Question

I am working on a web form in which I want (after submitting the form) to highlight those input fields that were not entered correctly.

The highlight effect I want to create is an endless looping animation between background-color: #fcc; and #fff; in erroneous input fields using jQuery. When one of these fields gets focus, I want to stop the animation of this field.

I am pretty versed in jQuery and JS, so if anyone could point me in the right direction, I would be sincerely grateful.

var PulsePut = function (){

    if ($(this).val() == "") {
        $(this).pulse({ backgroundColors: ['#ffffee', '#fff'] });

( ):

• , ""
• during the cycle, switch bg from the "wrong" classes, sleep at any long
• when you click enter, delete its “wrong” class.

this may not work if there is nothing executable in the while loop. post corrections in the comments.

I would capture the onblur event and activate the function to check input:

function matchShippingEmail() {
$('#shippingEmail').css('border',validColor);
if ($('#shippingEmail').val() == '') {
    $('#shippingEmailLabel').html('email');
    return 0;
}
if ($('#shippingEmail').val().match(RegExp('^([a-zA-Z0-9._%%-]+@+[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4})'))) {
    $('#shippingEmailLabel').html('email');
    return 1;
} else {
    $('#shippingEmail').css('border',invalidColor);
    $('#shippingEmailLabel').html(email error');
    return 0;
}

}

When submitting the form, I did the following:

$(document).ready(function() {
$('.confirmOrder').click(function(event){
    if (!matchCardOwnerName())        {$('#cardOwnerName').css('border',invalidColor);        $('#cardOwnerName').focus();        return false;}
    if (!matchCardNumber())            {$('#cardNumber').css('border',invalidColor);            $('#cardNumber').focus();            return false;}
    if (!matchCVV2Code())             {$('#CVV2Code').css('border',invalidColor);                $('#CVV2Code').focus();                return false;}
    if (!matchCardOwnerId())        {$('#cardOwnerId').css('border',invalidColor);            $('#cardOwnerId').focus();            return false;}
    if (!matchShippingFullName())    {$('#shippingFullName').css('border',invalidColor);        $('#shippingFullName').focus();        return false;}
    if (!matchShippingAddress())    {$('#shippingAddress').css('border',invalidColor);        $('#shippingAddress').focus();        return false;}
    if (!matchShippingCity())        {$('#shippingCity').css('border',invalidColor);            $('#shippingCity').focus();            return false;}
    if (!matchShippingZipCode())    {$('#shippingZipCode').css('border',invalidColor);        $('#shippingZipCode').focus();        return false;}
    if (!matchShippingEmail())         {$('#shippingEmail').css('border',invalidColor);        $('#shippingEmail').focus();        return false;}
    if (!matchShippingPhoneNumber()){$('#shippingPhoneNumber').css('border',invalidColor);    $('#shippingPhoneNumber').focus();    return false;}
    if (!$('#agreeToTermsAndConditions').attr('checked')) {
        $('#agreeToTermsAndConditionsDiv').css('color','#FF0000');
        $('#agreeToTermsAndConditionsDiv').css('font-weight','bold');
        $('#agreeToTermsAndConditionsDiv').css('font','150%% ariel');
        return false;
    }
    $('html').css('cursor','wait');
    $('.confirmOrder').css('cursor','wait');
    $('#confirmOrderButton').attr('src','images/confirmOrderDisabled.jpg');
    $('#paymentForm').submit();
    //document.paymentForm.submit();
    $('form').get(0).setAttribute('action', '#'); //this works

    return true;
});

});
