opt += "<button type=\"button\" class=\"sit_opt_del\"><i class=\"fa fa-times\" aria-hidden=\"true\"></i><span class=\"sound_only\">삭제</span></button></div>";
opt += "</li>";
여기서
opt_prc1 =number_format(String(price)) * 수량
이렇게 하고 싶은데요
var opt_prc1 = number_format(String(price)) * $("input[name='ct_qty["+item_code+"][]']").val();
이렇게 하니까 NaN으로 뜨네요
어떻게 하면 되나요?
