google-apps-script - 获取 Google 表单的最后回复

Question

我正在编写一个脚本来获取最后一次表单提交。我在网上找到了原始示例...

function onSubmit() {
  // Open a form by ID and log the responses to each question.
 var form = FormApp.openById('1G3e4FTYlsJUl5mKX2v1pYWauG1FO5IUPDIOI6P4hUoA');
 var formResponses = form.getResponses();
 for (var i = 0; i < formResponses.length; i++) {
   var formResponse = formResponses[i];
   var itemResponses = formResponse.getItemResponses();
   for (var j = 0; j < itemResponses.length; j++) {
     var itemResponse = itemResponses[j];
     Logger.log('Response #%s to the question "%s" was "%s"',
         (i + 1).toString(),
         itemResponse.getItem().getTitle(),
         itemResponse.getResponse());
   }
 }
}

我已将其修改为...

function onSubmit() {
  // Open a form by ID and log the responses to each question.
 var form = FormApp.openById('1G3e4FTYlsJUl5mKX2v1pYWauG1FO5IUPDIOI6P4hUoA');
 var formResponses = form.getResponses();

 var last_response = formResponses[formResponses.length - 1];
  Logger.log(last_response.val)
}

当我查看上面脚本的日志时，我得到未定义。如何输出last_response的值？

首先您需要使用 getItemResponses() 方法。 getItemResponses() 方法获取一份表单提交的所有“Items”。大多数项目都是问题。但有些项目不是问题，例如 PAGE_BREAK。所以你需要排除诸如分页符之类的东西。我将此代码中的项目称为问题，但项目并不总是问题。

function getArrayOfOneSubmissionsAnswers() {
  var allQuestions,i,itemType,L,thisAnswer,thisQuestion,thisSubmissionsAnswers;
    //Define all variables without assigning a value - value at this point
    //is undefined

  allQuestions = FormApp.openById('your_Form_ID').getResponses()[0].getItemResponses();

  L = allQuestions.length;//How many questions are there in the Form
  thisSubmissionsAnswers = [];//Create an empty array for answers

  for (i=0;i<L;i++) {//Loop through all the questions in this Form submission
    thisQuestion = allQuestions[i];//Get this question

    itemType = thisQuestion.getItem().getType();

    if (itemType === FormApp.ItemType.PAGE_BREAK) {
      continue;//keep looping
    };

    thisAnswer = thisQuestion.getResponse();//Get the answer
    Logger.log(i + " - " + thisAnswer); 

    thisSubmissionsAnswers.push(thisAnswer);//add answer to the array
  };

  Logger.log("thisSubmissionsAnswers: " + thisSubmissionsAnswers); 

  return thisSubmissionsAnswers;
};
