Javascript價格計算器的問題-價格未顯示

Question

我在制作一個簡單的價格計算器時遇到問題。 我已經學習過Javascript，並且遍歷了所有內容，而且看起來還不錯，但是由於最終價格沒有出現，我肯定會缺少一些東西。 我已經檢查了幾次，但也許它需要新的眼光：

<form action="" name="costcalculator" id="costcalculator" onsubmit="return false;"> // I put name and ID to be safe

    <b>1.</b> What type of website do you need?<br>
    <input type="radio"  name="typesite" value="Standard" onclick="calculateTotal()" />
    A standard website<br>
    <input type="radio"  name="typesite" value="Full Blog" onclick="calculateTotal()" />
    A website that allows visitors to leave comments on blog posts<br>

<center><input type='submit' id='submit' value='Submit' onclick="calculateTotal()" /></center><p>

<div id="totalPrice"></div> </form>

劇本：

var typesite = new Array(); // typesite is taken from the HTML
 typesite["Standard"]=20;
 typesite["Full Blog"]=30;

function getLayoutPrice() // new name for function
{  
    var layoutPrice=0; // new name for the variable
    var theForm = document.forms["costcalculator"]; // comes from form name/ID
    var typeSite = theForm.elements["typesite"]; // new variable name and name from HTML
for(var i = 0; i < typeSite.length; i++)
{
    if(typeSite[i].checked)
    {
        layoutPrice = typesite[typeSite[i].value];
        break;
    }
}
return layoutPrice; // taken from the variable created earlier
}

function calculateTotal()
{
    var totalPrice = getLayoutPrice();

    var divobj = document.getElementById('totalPrice');
    divobj.style.display='block';
    divobj.innerHTML = "Total Price would be about $"+totalPrice;

}

function hideTotal()
{
    var divobj = document.getElementById('totalPrice');
    divobj.style.display='none';
}

在當前的Chrome和Firefox中進行了測試，並且似乎可以正常運行，從下面的代碼段可以看出。

 var typesite = new Array(); // typesite is taken from the HTML typesite["Standard"]=20; typesite["Full Blog"]=30; function getLayoutPrice() // new name for function { var layoutPrice=0; // new name for the variable var theForm = document.forms["costcalculator"]; // comes from form name/ID var typeSite = theForm.elements["typesite"]; // new variable name and name from HTML for(var i = 0; i < typeSite.length; i++) { if(typeSite[i].checked) { layoutPrice = typesite[typeSite[i].value]; break; } } return layoutPrice; // taken from the variable created earlier } function calculateTotal() { var totalPrice = getLayoutPrice(); var divobj = document.getElementById('totalPrice'); divobj.style.display='block'; divobj.innerHTML = "Total Price would be about $"+totalPrice; } function hideTotal() { var divobj = document.getElementById('totalPrice'); divobj.style.display='none'; } 

 <form action="" name="costcalculator" id="costcalculator" onsubmit="return false;"> // I put name and ID to be safe <b>1.</b> What type of website do you need?<br> <input type="radio" name="typesite" value="Standard" onclick="calculateTotal()" /> A standard website<br> <input type="radio" name="typesite" value="Full Blog" onclick="calculateTotal()" /> A website that allows visitors to leave comments on blog posts<br> <center><input type='submit' id='submit' value='Submit' onclick="calculateTotal()" /></center><p> <div id="totalPrice"></div> </form>
