我正在尝试完成一个用于Build&为一辆有多种选择的房车定价。我已经对代码进行了尝试，但我既无法获得"总"价格来计算，也无法获得"图像切换"来工作。
在"Total"脚本上，我需要将其更改为39950.00的起价。不知道如何调整。我在这里得到了这个脚本：http://jsfiddle.net/b3p4r/
在"图像切换"脚本中，我不确定自己做错了什么。我在这里拿到了剧本，但剧本没有复选框。。。所以我不确定我错在哪里了。显示图像取决于两个输入单选按钮
图像切换说明
我对这个脚本的想法是，所有的图像都是格式化的，所以无论是否选择了一个选项，开关都会构建图像url。。。
我认为它应该如何工作。。。存在要确定的以下值。
graphicsValue-构建图像的第一部分。如果需要，这里有一个默认值。这是一台收音机，所以会选择一台。
雨篷值-构建图像URL的下一部分。如果需要，这里有一个默认值。这是一台收音机，所以会选择一台。
kingValue-构建图像URL的第三部分。。。如果不检查，该部分将没有值
solarValue-构建图像URL的第四部分。。。如果不检查，该部分将没有值
genbaskValue-构建图像URL的最后一部分，包括.jpg扩展名。如果未选中，则只返回.jpg以完成整个图像URL
因此，如果选择了图形样式3（gr-3）、灰色遮阳棚（awn灰色）ing Dome已选中（opt King）太阳能未选中（opt-Solar）1以及发电机吊篮已选中（option-genbask）2。。。当您切换这些选择中的每一个时，它都会实时返回这些值，即图像切换。
在上面的例子中，返回的URL是
/images/build/Red/RB+GA+KD+（无）+BA.jpg等于=/images/build/Red/RBGAKD.jpg（这是将要显示的图像。或者至少我希望它是这样工作的…但它不是。）

下一个脚本用于格式化总价。如果我想把它显示为输入，我可以让它工作，但我希望它显示在div中。我还需要弄清楚如何在这里添加起始价格。
<script type='text/javascript'>//<![CDATA[
window.onload=function(){
function formatCurrency(num) {
num = num.toString().replace(/$|,/g,'');
if(isNaN(num))

num = num.toFixed(2);
elements= num.split(".");
num = elements[0];
cents = elements[1];
for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)
{num = num.substring(0,num.length-(4*i+3))+','+
num.substring(num.length-(4*0+3));}
return (((sign)?'':'-') + '$' + num + '.' + cents)

$("input").change(function() {

$("input").each(function() {

编辑2：
正如承诺的那样，您的代码的工作版本：http://jsfiddle.net/kychan/PL6fU/
你有一些错误，比如：
$("#total").html(formatCurrency(total));
- DIV（通常）没有属性"value"。必须使用html（）使其可见
- 你的代码中没有给出checkvalue，所以我做了一个假人
总的来说，我认为这就是你想要的。如果没有，请随时更新，我会修复它！
注意：该代码远远不安全。我不确定你打算对代码做什么。JavaScript是在本地运行的，可以很容易地中断（例如在装有InternetExplorer6的旧计算机上）。
永远不要过于依赖JavaScript。如果你打算使用该代码进行购买，我必须建议你，客户可以很容易地更改价值。
提示：
如果可能的话，将代码封装在函数/类中。永远不要重复你以前写过的代码。
再次，将LOGIC与数据分离。switchcase包含图像的url，这对我来说就是数据。
您可以很容易地编写一个简单的循环来构建整个html。这减少了html和javascript代码。如果你想更改某些内容，只需应用一条规则即可更改整个格式！
想想建筑。你很有可能不是最后一个查看代码的人。如果有人想更改此代码，需要很长时间。。这就是为什么要将代码与数据分离（例如使用JSON）。然后，如果他们想添加另一个复选框，只需添加一行JSON即可！
天啊！重构代码花了很长时间。首先，强烈建议将数据和逻辑分开。。这将改进调试，并允许其他人以正常方式查看代码。
我花了两个（！！）小时才使代码正常工作。然后用五分钟添加您想要的功能。
从不。。再一次哈哈
以下是步骤：
- 存储包含（start+）总价的变量
- 从JSON自动生成字段/结构
- 为它们添加侦听器
- 单击单击
希望它能有所帮助（完整工作版本）：http://jsfiddle.net/kychan/rSVP7/7/embedded/result/
// storage of price (global).
var total = 39950;
// create list from JSON.
createList();
// show price in test div at start.
priceView.html(formatCurrency(total));
// function to update price on change.
function update(box) {
// calculate the price from the value of the selected box.
var price = parseInt(box.value, 10);
price = (isNaN(price)) ? 0 : price;
// if it is selected, you add the price.
if (box.checked) total += price;
// if not, then remove the price.
else total -= price;
// show the price on a test div.
priceView.html(formatCurrency(total));
// the image to load.
//img.html('<img src="{0}" />'.f($(box).data('img')));
img.html($(box).data('img'));
}
