关于Google表格/日历的旧问题的新答案

问题描述 投票:-2回答:1

我找到了此old question about synchronizing Google Sheets and Google Calendar,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,它提示此错误ReferenceError:未定义calenderId

因为我只能看到一行9,在哪里可以输入calendarId,所以我无法使脚本正常工作。

我是否错过了example中的一行?我知道我需要在第9行中写我的cal-id。

您收到的ReferenceError: calenderId is not defined错误消息是由于您声明的是calenderId而不是calendarId,并且整个代码都使用了calendarId

因此,为了解决错误,您可能需要检查声明变量的行并使用适当的名称进行声明。
