【问题描述】：
我是 javascript 新手，我正在尝试在业务催化剂中创建一个动态的测验问题列表。通过 BC 的设置方式，您可以使用 {tags} 在页面上放置用户创建的信息。
也就是说，我正在尝试根据用户选择的值生成测验问题列表。我创建了一个对象“问题”，并将必要的属性及其值放入下面新定义的对象中。
在我的代码中，我目前正在尝试：
1 - 定义问题对象类
2 - 定义 15 个可能的测验问题
3 - 编写一个 for 循环，该循环将根据前一个问题的键值编写每个问题。
我编写的函数/for 循环最终会这样做：
写第一题
如果 question1 键的值为“是”，则编写问题 2
如果问题 2 的键值为“是”，则写问题 3
等等，直到没有更多的“是”或第 15 题已经写完。
当我尝试执行下面的代码时，我收到错误“未捕获的 ReferenceError：问题未定义”有人可以帮助我了解我做错了什么吗？感谢您的所有帮助！
注意：为了节省空间，我只包含了三个问题变量。在我的实际代码中，我定义了 15 个问题对象。

【问题讨论】：
-
我认为你不能这样做：问题[i]
-
代码认为你正在尝试使用一个名为 question 的数组。
-
这甚至不是有效的代码。你确定你都贴了？
question应该是什么变量？ -
@MiniRagnarok 谢天谢地你提醒了我。但是，我指的是他从不关闭顶部的功能。显然问题变量是一个问题。
-
@MiniRagnarok 果然。恭喜你。
