Answer 1

Try using this code in input event on change

input.addEventListener("change", function() {
var inputVal = parseInt(input.value);
var selectVal = parseInt(select.value);

if (inputVal < selectVal) {
pieces.value = inputVal;
stacks.value = 0;
} else {
stacks.value = Math.floor(inputVal / selectVal);
pieces.value = inputVal % selectVal;
}

if (input.value === "") {
input.value = 0;
pieces.value = 0;
stacks.value = 0;
}
});
