无法访问 FormResponse 中的所有 ItemResponses

Question

我在附加到 Google 表单的 Apps 脚本函数中发生了一个奇怪的错误。

我调用响应，然后将它们列在一个数组中。日志显示数组中有6项，匹配六种形式的问题：

[18-05-08 00:13:31:900 AEST] [ItemResponse, ItemResponse, ItemResponse, ItemResponse, ItemResponse, ItemResponse]

当我调用前两个时，它工作得很好。再多了，它就会出错并说 undefined.

// Open a form by ID and log the responses to each question.
var form = FormApp.getActiveForm();
var formResponses = form.getResponses();
for (var i = 0; i < formResponses.length; i++) {
  var formResponse = formResponses[i];
  var editUrl = String(formResponse.getEditResponseUrl());
  var theResponseId = formResponses.indexOf(form);
  var itemResponses = formResponse.getItemResponses();
  var timestamp = formResponse.getTimestamp();  
  var firstName = itemResponses[0].getResponse();
  var lastName = itemResponses[1].getResponse();
  Logger.log(itemResponses); // Log shows there are 6 objects in the array. Matching the amount of Form Questions.

  // If I try to use these variables below, it doesn't work and the script 'breaks' at this point.

  //var number = itemResponses[2].getResponse();
  //var email = itemResponses[3].getResponse();
  //var firstName2 = itemResponses[4].getResponse();
  //var comments = itemResponses[5].getResponse();
}

注意：我已经尝试 FormApp.openById('id'); 看看获取活动表单是否有问题。这没有帮助。

Answer 1

这是因为一些答案是提交给 2 个问题的表单。如果您在更新表单之前提交了一些回复，这些新问题的答案将为 "undefined".
