Валидиране на jQuery за текстово поле и радио бутони

Блоковете IF се нуждаят от ELSE IF и затварянето трябва да е вътре в блока IF. и проверете за! (не) радиото е проверено. и няма нужда да връща false.

 if (!$('[name="sessionDocuments"]').is(':checked')){
    $('#sessionReason .validation-summary-errors').show();
    $("#sessionDocumentMessage label").addClass("redtext");
 }
 else if (sessionReasonBox == "") {
    $('#sessionReason .validation-summary-errors').show();
    $("#sessionReasonMessage").addClass("redtext");
    //return false;
 }
 else {
    $('#sessionReason .validation-summary-errors').hide();
    $("#sessionReasonMessage").removeClass("redtext");
    $(this).dialog("close");
 }

Ето го цигулката

Поправих проблема с кода по-долу:

РАБОТЕЩА ДЕМО

По-долу е кодът за същото
