未捕获的类型错误:无法读取未定义的属性“c1”，但找不到键入错误的内容

Uncaught TypeError: Cannot read property 'c1' of undefined but can not find what is typed wrong

本文关键字：错误 c1 找不到未定义类型读取属性更新时间：2023-09-26

我做了很多研究，我之前在其他页面上犯过这个错误，并发现了这些错误，但这次我找不到问题所在。有一次，只是将函数的名称更改为比原始工作更短的代码字。还有一次，我在"c"后面缺少一个数字，或者有两个相同的数字。这一次，这些似乎都不是问题所在。这次我做错了什么？:P 谢谢！.ps 已经查看了两天的这段代码。我的朋友也找不到我的错误，但他并不精通JS。

此外，Chrome和Firefox都会发生错误，所以我假设我在某处犯了编码错误。谢谢！

更新：我正在为我的 html 使用 4.01 过渡。而且，我确实检查了以确保"填字游戏"在所有三个地方都是相同的。此外，我没有包括输入框组之间的所有"字母"，因为这些都是基本的 html，而不是错误所在。谢谢！
