text박스에 onkeypress이벤트와 onkeyup이벤트에 스크립트 함수를 걸었습니다.

onkeypress -> 숫자를 누르기 전 숫자를 다른 text박스에 저장
onkeyup -> 변경된 숫자를 받아서 onkeypress 에서 저장한 수와의 차이를 전체합계 text박스에 더합니다.

이렇게해서 항상 전체합계가 계산되도록 하려고하는데

문제는 text박스에 처음 수를 쓸때는 잘 되지만 커서가 다른곳으로 이동할때도 onkeyup 이벤트가 일어나더군요

그래서 계산이 불필요하게 한번 더 일어나고 결과적으로 전체합계가 달라지게 되는 현상이

onkeyup 이 이벤트를 숫자키만 눌렀을때 일어나게 할 수 있나요?

아니면 커서가 옮겨질 때만이라도 안일어나게 하는 방법이나 다른 이벤트가 있으면 부탁드립니다.
