Question

我正在尝试制作一个表单，该表单应按所问问题确定的顺序创建一个数组。我正在尝试使用js，但是却很难，没有经验。它不起作用并不令我感到惊讶。不知何故变量没有值。我已经做过的事情很可能是愚蠢的，我认为可以将其简化一些;-)。希望有人看看我的代码，并帮助我解决这个问题。

Answer 1

是的，您的代码有很大的改进潜力，但是我将把这一部分留给您。

您正在使用

document.getElementsByName(vr1_1);

您实际要使用的时间

document.getElementsByName('VR1');

为您提供所有名称为VR1或使用的元素的NodeList

document.getElementById('vr1_1').checked;

明确获取特定元素（此处为vr1_1）以检查其选中状态。

使用表格填充数组
