【中文标题】提交表单后发送电子邮件的 Google 表单应用脚本

【英文标题】：Google form Apps Script to send email after form submission

【发布时间】：2021-11-11 18:32:53

【问题描述】：

我正在尝试修改 here 和 here 解释的 google-form 应用脚本。 该脚本运行良好，没有任何问题。 但我的问题是，在从主题列表中选择其中一个选项之前，此脚本不会发送电子邮件。而且在我的表格中没有主题和任何选项。

我的要求

我想要一个脚本，即使没有选择主题列表中的选项，也会自动响应。

例如。该脚本应该可以在没有 Topics 选项的 google-form 的情况下工作。

请帮我修改这个脚本。 非常感谢您的帮助。

原始的 Google 表单

【参考方案1】：

尝试替换

  if (topics.length > 0) 

...与：

  if (!topics.length) 
    topics = ['(no topics selected)'];
  
  if ((true))
