我正在整理一份调查问卷，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，该值按照我需要的方式进行加权。我有一个 javascript 函数，当我选择单选按钮时，它会更改值，但是，即使首次加载页面，由于某种原因，值也会从 75 开始。我需要第一个问题 1A 的值为 0、3 或 5，然后一旦回答了问题 1B，该值就会更改为 0、3、5、6、8 或 10。换句话说，新选择的值radio值从1A开始加到radio值上。以下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()
});
});
我已将代码粘贴到 JSFiddle 中:
https://jsfiddle.net/Dhaderlie/bkdqaxnL/
如果您测试该表单，您会看到我得到的奇怪值。
最佳答案
您的代码是正确的。
文档就绪后，您将获得所有检查值的总和。考虑到加载页面时，您总是检查所有单选按钮，您只需获取所有检查值的总和。
您只需从单选按钮中删除 checked 属性，然后在回答问题时即可正确更新结果。
在下面的 jsfiddle 中，我刚刚更改了您的示例，从第二个问题中删除了 checked 属性，这次您的输出从 70 开始(因为如果选中，第二个答案会多获得 5 分)

我希望这是有道理的
