我正在为我正在开发的商业催化剂网站创建一个测验。我正在使用 javascript Object Oriented Programming 在页面上动态创建问题。
以下是当前页面的运行方式：
1) 我定义了一个名为 question 的对象，它具有与回答表单字段相关的几个属性。
2) 我创建了一系列具有相关属性的新问题。
3) 运行创建问题的 for 循环函数
4）接下来，用户为他们的测验答案选择单选按钮
5) 当用户单击提交按钮时，运行一个函数来评估用户的答案并根据正确答案对其进行衡量。
6) 另一个功能运行来统计和记录用户在答题表中的分数。
7) 最后一个函数提交表单字段以永久记录用户的答案并重定向到通过/失败页面。
我有步骤1-4下来。我在步骤 5 中遇到了用户分数部分的问题。我需要运行一个脚本来评估用户的分数，但为了做到这一点，我需要获取并记录所选单选按钮的值。到目前为止，我已经检查了几个不同的单选按钮评估脚本，它们都出现了错误。
那里的任何人都可以帮助我了解如何获得无线电组的选定值吗？我有 2 或 4 个单选按钮组，具体取决于多项选择或真/假。这是我的代码：

会生成问题 - 在回答完所有问题后，会有一个提交按钮。同时，我有一个测试按钮来运行该功能。
编辑：这是最相关的代码：

};
