Attribute Error: 'Window' has no object 'nameE'
Attribute Error: 'Window' has no object 'nameE'
谁能解释一下 AttributeError: 'Window' object has no attribute 'nameE' 是什么意思。在过去的一个小时里，我一直在修改我的代码，试图找到一个解决方案，但没有成功。我认为它与 class 'Window' 有关，但我不确定它是什么。如果有人可以快速扫描代码以查看他们是否可以找到出现错误的原因，我将不胜感激。谢谢。
这是我的代码：

您正在使用相同的 SubmitInfo 函数，该函数调用所有条目，但只有部分条目是通过选择 SignupPage 或 LoginPage
