当ajax调用时，Jquery日期给出错误

Question

Jquery在托管应用程序后给出错误，但在VS2013中调试时工作正常。如果选择10或以上，则错误是日期，但如果日期低于10，则工作正常。

$('#btnSaveInternalMeeting').bind('click', function () {

            if ($('#IMeetingDate').val() == "") {
                alert('Please select date.');
                return false;
            }

            var InternalCaller = "", InternalMeetingAttendees = "";
            $('.removeInternalCaller').each(function (i, obj) {
                InternalCaller += $(this).attr('tag') + ",";
            });

            if (InternalCaller.length < 2) {
                alert('Please select atlest one attendees...');
                return false;
            }

            $('.removeInternalAttendees').each(function (i, obj) {
                InternalMeetingAttendees += $(this).attr('tag') + ",";
            });

            if (InternalMeetingAttendees.length < 2) {
                alert('Please select atlest one attendees...');
                return false;
            }
            if ($('#btnSaveInternalMeeting').val() == 'Save') {

                    }
                });
            }
