【中文标题】用于计算带有单选复选框和下拉项的提交表单的 Javascript【英文标题】:Javascript to calculate a submission form with radio checkbox and dropdown items 【发布时间】:2014-12-01 03:38:18 【问题描述】:我正在尝试让表单计算总数,因为项目是从单选/下拉/检查框的组合中选择的,并在底部显示总数并能够提交表单。
这就是我所拥有的:http://jsfiddle.net/XD8RW/1430/ 当您单击不同的选项时,总数不会显示在中间部分

<p>
<br>I generally don't charge extra for exterior paint unless you want something very detail-oriented or a design that would consume a large ammount of my paint/require me to buy additional paint colors (I only have red white and green paints for the holidays)
<br>Some figures are size/paper specific
<br>Money figures are limiited as to what can/can't be made, as are foiled figures as the foiled paper is sometimes difficult to work with
<br>When you contact me to place an order, I'll send you an e-mail back with pricing information specifically for your order</p>

js 是 jsfiddle 形式 抱歉,如果我发布了这个错误,我是新来的堆栈溢出
【问题讨论】:
【参考方案1】:就像 che-azeh 所说,有些变量不匹配。 您想使用 selectedornaments 数组 (theForm.elements["selectedornament"])。这里命名为 selectedCake(您可能想要更改它)。 size_prices 应该是您定义为装饰品价格的数组。 适用于http://jsfiddle.net/XD8RW/1432/
function getOrnamentSizePrice()
var ornamentSizePrice = 0;
//Get a reference to the form id="orderform"
var theForm = document.forms["orderform"];
//Get a reference to the size the user Chooses name=selectedOrnament":
var selectedCake = theForm.elements["selectedornament"];
//there are 2 radio buttons selectedornament.length = 2
//loop through each radio buttons
for (var i = 0; i < selectedCake.length; i++)
//if the radio button is checked
if (selectedCake[i].checked)
//we set ornamentSizePrice to the value of the selected radio button
//by using the ornament_prices array
//and get the selected Items value
ornamentSizePrice = ornament_prices[selectedCake[i].value];
//If its a match then break out of this loop
//No reason to continue
break;
//return the ornamentSizePrice
return ornamentSizePrice;
虽然您会想要仔细检查您的 decorator_prices 数组的值
【讨论】:
非常感谢!这帮了很多忙。【参考方案2】:在 Firefox (ctrl+shift+k
) 等 Web 控制台上检查您的代码。你会注意到你有几个未定义的变量,比如selectedornament
和size_prices
,它们让你搞砸了。您还可以使用它来检查其他错误。

仍然没有关注。我对 js 了解不多,并且有一个必修课的读书老师。他整个学期都没有教我们任何东西,明天期待一个小组项目。我试图把这个页面放在一起。我试图复制一个 js 表单并使用提供的说明尝试对其进行修改,但我无法对其进行正面或反面。我花了五个多小时试图弄清楚并尝试自己学习和理解这个烂摊子。以上是关于用于计算带有单选复选框和下拉项的提交表单的 Javascript的主要内容,如果未能解决你的问题,请参考以下文章
