如何在 Google 测验中添加带有正确答案的多项选择题

Question

This is the google sheet [ESH - B1.1 - Exam 2]

Google Script is: examMakerQA

I am very new to scripting. In the sheet, I wish to add True / False to the options of Multiple Choice Questions [Col P to Col Z]. So that I don't have to manually add correct answers in Google Form.

//Make Multiple-Choice question
function makeMultipleCQ(d, form){
  var mcItem = form.addMultipleChoiceItem();
  mcItem.setTitle(d[1]);
  if(d[2] !== "N"){mcItem.setPoints(d[2])};
  if(d[4] === "Y"){mcItem.setRequired(true);}
  
//Filter blank cells
  var options = d.splice(5,10);
  var options = options.filter(function(x){return x !== ""});
  var corrects = d.splice(15, 20); // data with true, false 
  var corrects = options.filter(function(x){return x !== ""});
     
//Loop through options and add to question  
  **var ch = options.map(function(option, op){
  var tf = false;
  if(op === d[3]){tf = true};
    
  return mcItem.createChoice(option, tf)** 
  });
  
  mcItem.setChoices(ch);
  
  var correctFeedback = FormApp.createFeedback()
      .setText(d[3])
      .build();
  mcItem.setFeedbackForCorrect(correctFeedback);
  
  }

Answer 1

Currently you are comparing the index op against the answer key in column D.

What you need to do instead is to evaluate the entries in columns P to Z corresponding to the index op against TRUE or FALSE

To do this you can modify your code as following:

function makeMultipleCQ(d, form){
  var mcItem = form.addMultipleChoiceItem();
  mcItem.setTitle(d[1]);
  mcItem.setTitle(d[1]);
  if(d[2] !== "N"){mcItem.setPoints(d[2])};
  if(d[4] === "Y"){mcItem.setRequired(true);}
  
  //Filter blank cells
  var options = d.splice(5,10);
  var options = options.filter(function(x){return x !== ""});
  //after the previos splice the original array and consequently the indeices has been modified
  var ops = d.splice(5,10);
  var ops = ops.filter(function(x){return x !== ""});
  //Loop through options and add to question  
  var ch = options.map(function(option, op){
    var tf = ops[op];
    return mcItem.createChoice(option, tf); 
  });
  
  mcItem.setChoices(ch);  
  var correctFeedback = FormApp.createFeedback()
  .setText(d[3])
  .build();
  mcItem.setFeedbackForCorrect(correctFeedback);  
}
