    var check1=0;
    $('#tambahform').submit(function(e){
    if (check1==0){
        $("#addModal").animate({scrollTop:0}, 'slow');
    }else{
        e.preventDefault();
        var formData = new FormData($(this)[0]);
        $.ajax({

                window.location.reload(true);
            }
        });
    }
    return false;
    });
