Answer 1

您有以下问题之一：

• ss.getSheets 函数返回 undefined _{（阅读文档后我发现这是不可能的）}
• e.parameters 对象的以下属性之一不存在：
  • 序列
  • pytanie1
  • pytanie2

你可以添加一些console.log来看看哪个是不存在的属性...

Answer 2

尝试去掉e.parameters.pytanie2[0]

之后的逗号（,）

var 行 = [

new Date(),                     // Timestamp
e.parameters.serial[0],         // Serial Number
e.parameters.pytanie1[0],        // Pytanie 1
e.parameters.pytanie2[0]**,**        // Pytanie 2

];
