javascript - 单选按钮值未解析

我正在构建一个积分计算系统，该系统根据输入值计算积分。我在这个单选按钮上使用了一些 jquery ui 样式，但现在它总共没有加起来。代码太长，无法在此处发布，因此请检查此 live preview 。我通读代码很多次都找不到任何东西。

编辑:这是我的代码的精简版本:问题出在 div 第 2 部分中的单选按钮，请阅读我的评论。

最佳答案

我不认为它链接到jquery ui，而是链接到行

var tcfc2 = parseInt(document.getElementById('form').TCFC2.value, 10) || 0;

由于您有 2 个带有名为 TCFC2 的单选按钮的元素，因此将使用它们创建一个数组。此外，第一个 radio 的值始终为 1，第二个 radio 的值始终为 2。您需要检查“checked”属性，而不是确定人们是否讲法语的值。

var tcfc2 = document.getElementById('form').TCFC2[0].checked -0 ;

没有parseInt，因为返回“true”或“false”，“-0”是强制int转换。

最后，我会将 radio 或输入类型文本重命名为 TCFC2 之外的其他名称。 (并合并你的CSS，将脚本和样式从html文件中取出并放入它们自己的文件中以进行维护，并将你的变量命名为比a、b和c更有意义的名称......)
