.duplicate()
方法在表单之间不起作用(不是我所见),所以我编写了一个快速例程,将多项选择项从一个表单复制到另一个表单。
(我这样做是为了在Classroom
中设置测验。我在形成性评估的测验中有一系列关于单一主题的问题,并希望将这些问题的随机问题结合起来进行总结性评估。)
我写的代码可以很好地复制问题而不是反馈。这是我的第一个GAS代码,所以道歉!
TypeError:在对象
getFeedbackForCorrect
中找不到函数Item
。 (第32行,文件“代码”)
function copyMultipleChoiceItem(item1, item2) {
// copies MC question item1 to item2 - tested PDW 17/05/20
// copy of feedback not working
//
// basic question items
item2.setTitle(item1.getTitle());
item2.setPoints(item1.asMultipleChoiceItem().getPoints());
item2.setRequired(item1.asMultipleChoiceItem().isRequired());
item2.setHelpText(item1.getHelpText());
// the choices
var choices = item1.asMultipleChoiceItem().getChoices();
for (var i = 0; i < choices.length; i++) {
item2.createChoice(choices[i].getValue(),choices[i].isCorrectAnswer());
}
item2.setChoices(choices);
// the feedback and links - cannot get this to work!
var feedback1 = item1.getFeedbackForCorrect();
var feedback2 = FormApp.createFeedback()
.setDisplayText(feedback1.getText());
// then do list of URLs
item2.setFeedbackForCorrect(feedback2);
}
答案 0 :(得分:1)
您需要将item1
作为多项选择。 getFeedbackForCorrect
上没有item
方法。您可以为项目创建一个新变量作为多项选择。
var itemAsMultipleChoice;
itemAsMultipleChoice = item1.asMultipleChoiceItem();//Get item as multiple choice item
然后使用新的itemAsMultipleChoice
变量;
var feedback1 = itemAsMultipleChoice.getFeedbackForCorrect();
以下是整个功能:
function copyMultipleChoiceItem(item1, item2) {
// copies MC question item1 to item2 - tested PDW 17/05/20
// copy of feedback not working
//
// basic question items
var itemAsMultipleChoice;
Logger.log('item1: ' + item1)
itemAsMultipleChoice = item1.asMultipleChoiceItem();
item2.setTitle(item1.getTitle());
item2.setPoints(item1.asMultipleChoiceItem().getPoints());
item2.setRequired(item1.asMultipleChoiceItem().isRequired());
item2.setHelpText(item1.getHelpText());
// the choices
var choices = item1.asMultipleChoiceItem().getChoices();
for (var i = 0; i < choices.length; i++) {
item2.createChoice(choices[i].getValue(),choices[i].isCorrectAnswer());
}
item2.setChoices(choices);
var feedback1 = itemAsMultipleChoice.getFeedbackForCorrect();
var feedback2 = FormApp.createFeedback()
.setDisplayText(feedback1.getText());
// then do list of URLs
item2.setFeedbackForCorrect(feedback2);
}
