但不僅不是輸入字段，而是選項，是/否。

不，但寫一個很容易......下面非常簡化的例子：

<script type="text/javascript">
var product1price = 85;
var product2price = 23;
function CalculatePrice()
{
    var totalprice = 0;
    if (document.getElementById('product1select').value == "yes")
    {
        totalprice += product1price;
    }
    if (document.getElementById('product2select').value == "yes")
    {
        totalprice += product2price;
    }
    document.getElementById('pricesum').innerHTML = totalprice;
}
</script>
<select id="product1select"><option value="yes">Yes</option><option value="">No</option></select>
<br><select id="product2select"><option value="yes">Yes</option><option value="">No</option></select>
<br>Total Price: <span id="pricesum">0</span>
<br><button onclick="CalculatePrice()">Get Price</button>
