無但寫起來會很容易......下面是一個非常簡單的例子：

<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>
