来自起始价格和掉期图像的总输入量，具体取决于选定的单选框和复选框

Question

我正在尝试使用多个选项来完成用于RV的构建和定价的脚本。 我已经对代码进行了尝试，但是我无法获得“总价”来进行计算或“图像切换”来进行工作。

在“总计”脚本上，我需要对其进行更改，使其起始价格为39,950.00。 不确定如何调整。 我在这里得到了这个脚本： http : //jsfiddle.net/b3p4r/

在“图像切换”脚本上，我不确定自己在做什么错。 我在这里得到了脚本，但是该脚本没有复选框...所以我不确定在这里有什么问题。 根据两个输入单选按钮显示图像

影像开关说明...

我对这个脚本的想法是所有图像都经过格式化，因此无论是否选择了一个选项，开关都将构建图像URL。

我认为它应该如何工作...以下值需要确定。

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，因此将被选中。

awningValue-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，因此将被选中。

kingValue-构建图像URL的第三部分...如果未选中，则此部分将没有任何值

solarValue-构建图像URL的第四部分...如果未选中，则此部分将没有值

genbaskValue-构建图像URL的最后一部分，包括.jpg扩展名。 如果未选中，则仅返回.jpg以完成整个图像URL

因此，如果选择了图形样式3（gr-3） ， 则选择了 灰色遮阳篷（遮阳灰） ， 选中了King-Dome（选择国王） ， 未选中Solar（选择了太阳能） ，并且选中了Generator Basket （选择了- genbask） ...当您切换这些选择中的每一个时，它将实时返回这些值，图像将切换。

在上面的示例中，返回的URL为

/ images / build / Red / RB + GA + KD +（无）+ BA.jpg等于= /images/build/Red/RBGAKD.jpg （这是显示的图像。或者至少这就是我的方式希望它能工作...但不是。）

下一个脚本是用来格式化总价的脚本。 如果要将其显示为输入，则可以使其正常工作，但希望将其显示在div中。 我还需要弄清楚如何在此处添加起价。

                       <script type='text/javascript'>//<![CDATA[ 
window.onload=function(){
function formatCurrency(num) {
  num = num.toString().replace(/\$|\,/g,'');
  if(isNaN(num))
   {num = "0";}
  sign = (num == (num = Math.abs(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() {
    var total = 0;
    $("input").each(function() {
        if($(this).is(":checked"))
            total += parseFloat($(this).val());
    });
    $("#total").val(formatCurrency(total));
});

Answer 1

编辑2：

如所承诺的，您的代码的有效版本： http : //jsfiddle.net/kychan/PL6fU/

您有一些错误，例如：

$("#total").html(formatCurrency(total));

• DIV（通常）没有属性“值”。 您必须使用html（）使其可见。
• 在您的代码中未提供check_value，所以我做了一个假人。

总的来说，我认为这就是您想要的。 如果没有，请及时更新，我会修复它！

注意：该代码是安全的FAR。 我不确定您打算如何使用该代码。 JavaScript在本地运行，并且很容易损坏（例如，在装有Internet Explorer 6的旧计算机上）。

切勿过于依赖JavaScript。 如果您打算将代码用于购买，我必须告知您客户可以轻松更改值。

温馨提示 ：

• 如果可能，将您的代码封装在函数/类中。 切勿重复您之前编写的代码。

• 同样，将LOGIC与数据分开。 开关盒包含图像的URL，对我来说，这些是数据。

• 您可以轻松地编写一个构建整个html的简单循环。 这减少了html和javascript代码。 如果您要更改某些内容，则只需应用一条规则即可更改整个格式！

• 考虑一下架构。 您很有可能不是最后调查代码的人。 如果有人想更改此代码，则将花费一些时间。这就是为什么将代码与数据分开（例如使用JSON）的原因。 然后，如果他们想添加另一个复选框，则只需添加一条JSON行即可使其生效！

---

真是的 重构代码花了很长时间。 首先，强烈建议将数据和逻辑分开。这将改善调试效果，并允许其他人以正常方式查看代码。

我花了两个 （!!）个小时使代码正常工作。 然后五分钟添加所需的功能。

再也不！ 哈哈

这些步骤是：

• 以（开始+）总价存储变量
• 自动从JSON生成字段/结构。
• 向他们添加听众。
• 单击单击单击。

希望对您有所帮助（ 完整的版本 ）： 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'));
