input들 값을 넘겨야해서 여분필드를 작성해놨습니다. 

그리고 input 옆에 +- 버튼을 두어서 버튼들을 누르면 input value 값이 1씩 증감 하는 스크립트도 짜놓은 상태입니다.

문제는 카운트가 증가할때마다  가격이 더해져서 종합이 나오게 하고싶은데요 ㅠㅠ 이부분을 어떻게 처리해야할지 모르겠습니다. 뭔가 배열과 for문을 이용하면 될것같기도한데 어찌 해야할지 감이 안잡힙니다..

count라는 class로 체크해서 jquery each 문으로 해서 해당 부분의 데이터가 변경될때마다 실행되도록 적용해 주시면 됩니다.


$(".up, .down").on("click", function() {
    var sum = 0;
    $(".count").each(function() {
        sum += parseInt($(this).val());
    });
    $(".result").val(sum);
});
