爲什麼我的Javascript價格計算器不工作？

我不能得到下面的腳本工作，我真的不明白爲什麼。應該正常工作爲什麼我的Javascript價格計算器不工作？

每個變量都會計入，但是沒有顯示價格？

var cake_prices = new Array(); 
cake_prices["filmtype1"]=5000; 
cake_prices["filmtype2"]=5000; 
cake_prices["filmtype3"]=5000;

    var theForm = document.forms["prisberegner"]; 
    var selectedCake = theForm.elements["selectedcake"]; 
    for(var i = 0; i < selectedCake.length; i++) 
    { 
     if(selectedCake[i].checked) 
     { 
      cakeSizePrice = cake_prices[selectedCake[i].value];

    DagePrice = dage_prices[selectedDage.value]; 

    return DagePrice;

function getSpeakPrice() 
{ 
    var SpeakPrice=0; 
    var theForm = document.forms["prisberegner"]; 
    var selectedDage = theForm.elements["speak"]; 


    SpeakPrice = speak_prices[selectedSpeak.value]; 

    return SpeakPrice; 
} 


function lydPrice() 
{ 
    var lydPrice=0; 
    var theForm = document.forms["prisberegner"]; 
    var lyd = theForm.elements["lyd"]; 
    if(lyd.checked==true) 
    { 
     lydPrice=1500; 
    } 
    return lydPrice; 
} 

function speakoverPrice() 
{ 
    var speakoverPrice=0; 
    var theForm = document.forms["prisberegner"]; 
    var speakover = theForm.elements["speakover"]; 
    if(speakover.checked==true) 
    { 
     speakoverPrice=1600; 
    } 
    return speakoverPrice; 
} 

function uspeakPrice() 
{ 
    var uspeakPrice=0; 
    var theForm = document.forms["prisberegner"]; 
    var uspeak = theForm.elements["uspeak"]; 
    if(uspeak.checked==true) 
    { 
     uspeakPrice=1000; 
    } 
    return uspeakPrice; 
} 

function musikPrice() 
{ 

    var musikPrice=0; 
    var theForm = document.forms["prisberegner"]; 
    var musik = theForm.elements["musik"]; 
    if(musik.checked==true){ 
     musikPrice=1200; 
    } 
    return musikPrice; 
} 


function storyPrice() 
{ 

    var musikPrice=0; 
    var theForm = document.forms["prisberegner"]; 
    var story = theForm.elements["story"]; 
    if(story.checked==true){ 
     storyPrice=1000; 
    } 
    return storyPrice; 
} 

function includecandlesPrice() 
{ 

    var includecandlesPrice=0; 
    var theForm = document.forms["prisberegner"]; 
    var includecandles = theForm.elements["includecandles"]; 
    if(includecandles.checked==true){ 
     includecandlesPrice=1000; 
    } 
    return includecandlesPrice; 
}   

function calculateTotal() 
{ 
    var cakePrice = getCakeSizePrice() + getSpeakPrice() + getFillingPrice() + getRejsePrice() + getDagPrice() + lydPrice() + speakoverPrice() + uspeakPrice() + musikPrice() + storyPrice() + includecandlesPrice(); 

    var divobj = document.getElementById('totalPrice'); 
    divobj.style.display='block'; 
    divobj.innerHTML = "Total Price For the Cake $"+cakePrice; 

} 

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

我應該感謝javascript-coder.com對於我試圖適應腳本模板。

1）不要使用'new Array（）';使用'[]'2）如果你需要的是對象，不要創建數組;使用'{}'4）如果你的對象是靜態的，把它們初始化爲對象文本的一部分5）'== true'通常是毫無意義的，但總是令人困惑6）控制檯中的任何錯誤？ – Ryan

打開你的瀏覽器的控制檯，你會看到'未捕獲的ReferenceError：selectedSpeak未定義（索引）：275' –

Ctrl-Shift-J在Chrome上打開瀏覽器控制檯。 –

如果你有

var selectedDage = theForm.elements["speak"];

應該

var selectedSpeak = theForm.elements["speak"];

否則selectedSpeak不被任何定義。

嘿，謝謝你的提示，這並沒有解析totalPrice，雖然 – Giveny

解決了它，也有一個小的其他錯誤。 – Giveny

SpeakPrice = speak_prices[selectedSpeak.value];

selectedSpeak變量未定義。根據您的要求定義它。
