write.skin.php 에서 사용하는 합산 소스입니다.
여분필드에 여러개의 값을 셀렉트하여 explode로 더해서 저장시키고 불러오는 방식인데요.
체크박스 방식으로 바꾸고 싶은데 input을 어떻게 표현해야하고 스크립트를 어떻게 변경해야할지 몰라서요.
조언 부탁드려봅니다.

<script language="javascript">
function itemSum(frm)
{
var sum = 0;
var count = frm.chkbox.length;
for(var i=0; i < count; i++ ){
if( frm.chkbox[i].checked == true ){
sum += parseInt(frm.chkbox[i].value);
}
}
frm.total_sum.value = sum;
}
</script>
이 스트립트로
<input name="chkbox" type="checkbox" value="1000" onClick="itemSum(this.form);" <?php echo ($buy1 == "1000") ? "selected" : "";?>>
이런식으로 처리했습니다. 감사합니다.

radio 가 아니고 checkbox 맞죠?
radio 1개만 선택 가능
checkbox 여러개 선택 가능
