从谷歌表单创建多项选择测验

Question

我正在尝试创建一个多项选择测验，它使用 GOOGLE FORMS 从问题库中提取问题，并将结果存储在电子表格中。我已经知道如何创建测验并将数据存储在电子表格中，但我不知道如何使用题库。谁能帮我解决这个问题？

提前致谢。

Answer 1

最近 Google announced 向 Google Apps Script Forms 服务添加了几种方法，使其能够以编程方式处理 Google Forms 测验。

多亏了这一点，现在可以使用Google Apps Script 从 Google 表格题库创建测验。这实际上与从电子表格创建 Google 表单相同。

我也对这个话题很感兴趣，但我是个新手。 从现有的代码中汲取灵感，我编写了一个简单的脚本，令我惊讶的是，它似乎可以工作。 我将在下面对其进行描述，但请记住，这篇文章更多的是问题，而不是答案。我想听听更有经验的程序员的意见，因为我不确定我做的一切是否正常。

所以在我的简单方案中，问题库看起来是like this（请自己制作副本）。它应该是不言自明的，但是

A 列：ID（目前未使用，但将来可能有用）；

B 列：应该包含问题的文本（目前只有 Q1、Q2 等占位符）

C 列：每个问题的多项选择数

D列：正确的选择（其序号在以下列）

E列及以下：多项选择的文本，与C列一样多（同样，暂时只有占位符。A3Q2是问题2的答案3）；

脚本如下。我在里面放了很多cmets。 基本上，它会创建一个名为“QBANK_1_form”的表单，其中包含电子表格中列出的多项选择题的子集。 该表单在由变量destinationFolder 指定的文件夹中创建。该脚本确保没有重复文件（我在调试时得到了很多）。

再次，我真的很想从更严肃的程序员那里得到一些见解。这是我的第一次尝试，可能非常笨拙。我什至很惊讶它的工作原理。

   function myFunction() {
  // Id of the spreadsheet containing the question bank
  var questionBankId = "1QCO-W2PxR9sLf2HtXreaEslyGTBdjswTgqxWDFycgKc"; 
  // name of the output form
  var formName = "QBANK_1_form"; 
  // Id of the destination folder (not root to keep things tidy)
  var destinationFolder = "ID_OF_YOUR_FOLDER_HERE"; // <-- change accordingly
  // variable containg the total number of questions in the question bank (read from spreadsheet)
  var question_num;
  // number of questions in the output form (question_req <= question_num)
  var question_req = 3; // chosen programmatically for the moment
  // other variables
  var r;
  var c;
  var ans;
  var item;
  var content;
  var choices =[];
  var nchoices;
  var correct;
  var iscorrect;

  // ======================================================================================

  // check if other files with the chosen name exist in the folder, 
  var thisFile = myFolder.getFilesByName(formName);
  // if this is the case, iterate over them
  while (thisFile.hasNext()) {
    // get next file
    var eachFile = thisFile.next();
    // get its Id
    var idToDLET = DriveApp.getFileById(eachFile.getId());
    // delete the file
    DriveApp.getFolderById(destinationFolder).removeFile(idToDLET);

  // add the to the desired folder
  DriveApp.getFolderById(destinationFolder).addFile( formFile );
  // delete the file from the roor folder
  DriveApp.getRootFolder().removeFile(formFile);
  // ======================================================================================

  // open spreadsheet containing the question bank
  var ss = SpreadsheetApp.openById(questionBankId);

  var sheet = ss.getSheets()[0];
  question_num = sheet.getLastRow() - 1;
  // if question_req > question_num then set question_req=question_num, and the following is just a reshuffling of
  // the questions in the question bank
  if(question_req>question_num) {
     question_req=question_num;
  }
  // get random indexes for the question subset
  var index = questions(question_num,question_req);

  // Make sure the form is a quiz.
  form.setIsQuiz(true);


  // iteration of reading spreadsheet and writing form accordingly
  for(r = 0; r<question_req  ; r++){
     // create new multiple choice question
     item = form.addMultipleChoiceItem();      
     // set value if correct
     item.setPoints(10);
     // get question text from question bank and write it in form
     content = sheet.getRange(index[r]+1,2).getValue();
     item.setTitle(content);
     // get number of choices from question bank
     nchoices = sheet.getRange(index[r]+1,3).getValue();
     // get position of correct choice from question bank
     correct = sheet.getRange(index[r]+1,4).getValue();
     // create choice array
     for(c = 1; c<nchoices+1;c++){
        // determine whether the choice is correct
        iscorrect = (c==correct);
        // read choice from question bank
        content = sheet.getRange(index[r]+1,c+4).getValue();
        // add choice to choice array
        choices[c-1] = item.createChoice(content,iscorrect);           
     }
     // set choices
     item.setChoices(choices);

  }
}
