從谷歌表單創建一個多選題測驗

Question

我想創建一個選擇題測驗，這需要從一個問題銀行的問題，使用GOOGLE表格和結果存儲在電子表格中。我已經知道如何創建測驗並將數據存儲在電子表格中，但我不知道如何使用問題庫。誰能幫我這個？

在此先感謝。

Answer 1

最近Google announced他們向Google Apps Script Forms服務添加了多種方法，使其能夠以編程方式處理Google表單測驗。

感謝此，現在可以使用Google Apps Script從Google表格問題銀行創建測驗。這與從電子表格創建Google表單幾乎相同。

Answer 2

我很感興趣這個話題太，但我是一個完整的新手。 從現有的代碼中獲得靈感，我編寫了一個簡單的腳本，令我非常驚訝，似乎工作。 我在下面描述它，但請記住，這篇文章更多是問題而不是答案。我希望得到更有經驗的程序員的意見，因爲我不確定我做的一切都是正確的。

因此，在我的簡單方案中，問題銀行看起來像like this（請製作您自己的副本）。它應該是不言而喻的，但是

列A：Id（迄今未使用，但可能在未來有用）;

B欄：應包含問題的文本（迄今只有像Q1，Q2等的佔位符）

柱C：爲每個問題

列d多種選擇號碼：所述正確的選擇（它的訂單號碼在下面的列中）

E列和以下：C列中的多個選項的文本（同樣，目前只有佔位符A3Q2是問題2的答案3 ）;

腳本如下。我在裏面寫了很多評論。 基本上它會通過名稱「QBANK_1_form」創建一個表單，其中包含電子表格中列出的多項選擇題的子集。 表單在變量destinationFolder指定的文件夾中創建。該腳本確保沒有重複的文件（我在調試時得到了很多這些文件）。

再次，我真的很想從更嚴肅的程序員那裏獲得一些見解。這是我第一次嘗試，可能很笨拙。我甚至對它的工作感到驚訝。

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

    question_num = sheet.getLastRow() - 1;

    form.setIsQuiz(true); 


    // iteration of reading spreadsheet and writing form accordingly 
    for(r = 0; r<question_req ; r++){

    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();
