关于 Google Sheets/Calendar 旧问题的新答案
New answer to old question about Google Sheets/Calendar
我找到了这个 并尝试下载模板然后进行相应的编辑。
当我尝试 运行 脚本时提示此错误 ReferenceError: calenderId is not defined.
因为我只能看到一行 9，所以我无法让脚本工作。
我在 example 中漏掉了一行吗？我知道我需要在第 9 行写下我的 cal-id。

您收到的 ReferenceError: calenderId is not defined 错误消息是由于您声明 calenderId 而不是 calendarId 并且您在整个代码中使用 calendarId .
因此，为了修复您的错误，您可能需要检查声明变量的行并使用适当的名称声明它。

您收到的 ReferenceError: calenderId is not defined 错误消息是由于您声明 calenderId 而不是 calendarId 并且您在整个代码中使用 calendarId .
因此，为了修复您的错误，您可能需要检查声明变量的行并使用适当的名称声明它。
