【问题描述】：
我正在整理一份问卷，其中每个问题都有 4 个单选按钮选项。单选按钮附加了一个值，按我需要的方式加权。我有一个 javascript 函数，当我选择一个单选按钮时，它会更改值，但是，即使首次加载页面时，由于某种原因，值从 75 开始。我需要第一个问题 1A 的值是 0、3 或 5，然后一旦问题 1B 被回答，值就会变为 0、3、5、6、8 或 10。换句话说，新选择的值radio 被添加到从 1A 开始的 radio 值的值。这是我表格中的前几个问题。

这是我的 javascript 函数：
function calcscore(){
var score = 0;
$(".calc:checked").each(function(){
score+=parseInt($(this).val(),10);
});
$("input[name=sum]").val(score)
}
$().ready(function(){
$(".calc").change(function(){
calcscore()
});
});
我已将我的代码放入 JSFiddle 中：

如果您测试表单，您会看到我得到的奇怪值。
