从Google表单获取最后一个响应

Question

我正在编写一个脚本，以获取最近提交的表单。我在网上找到了一个原始示例...

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)
}

当我查看上述脚本的日志时，我得到undefined。如何输出last_response的值？

Answer 1

首先，您需要使用getItemResponses()方法。 getItemResponses()方法获取一个表单提交的所有“项目”。 大多数项目都是问题。 但是有些项目不是问题，例如PAGE_BREAK。 因此，您需要排除诸如分页符之类的内容。 在此代码中，我将项目称为Questions，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;
};

仅供记录，这是Sandy上面的脚本稍微修改后的版本，它可以给我提供从表单提交的最后一个响应。

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

  number_of_submissions = FormApp.openById('your_Form_ID').getResponses().length;
  allQuestions = FormApp.openById('your_Form_ID').getResponses()[number_of_submissions - 1].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;
};
