Google Forms Apps 脚本 - 随机缺少选项

Question

这个错误让我完全困惑。我正在自动创建一个 google 表单（测验）。周期性地（但经常）多项选择项 缺少选项 ，这种情况经常发生 一旦页面刷新 。也就是说，答案选项看起来像是在屏幕上正确创建的，但是，一旦您刷新它们就会消失。奇怪的是（有趣的是）Stackdriver 中没有错误。

视觉上这就是正在发生的事情。这两个图像都是在运行使用相同的输入为两种不同的形式使用相同的脚本时创建的：

如您所见，第一个已创建并有 4 个选项，第二个已创建且只有 1 个选项。

它经常发生，但并非总是如此。看起来它几乎是一个 Google 错误，但是，我搜索了他们的跟踪器，没有人报告任何东西。

我会展示我们的“选择创建代码”，以防它指向任何东西，但是，我们使用 完全相同的输入 得到不同结果的事实表明还有其他东西进行中。

我只是展示了循环的一部分，但正如我所说，代码根本没有错误。有没有一种方法可以创建比运行应用程序脚本插件更好的大型（30 个问题）Google 表单？我希望有一个 API :(

无论如何，如果这是一个已知问题，或者有解决方法，我很想听听。

      var item = form.addMultipleChoiceItem();
      item.setPoints(points);

      if (data.answer_sheet) { item.setTitle("Question " + position) }

      var choices = [];

      for (var i=0; i < question.count; i++) {
        choices.push(item.createChoice(String.fromCharCode(65 + i), i+1 == question.correct));
      }

      item.setRequired(required);
      item.setChoices(choices);

编辑 - 最小可重现错误

如果将以下脚本复制到 google-apps-script 环境和运行脚本中，它应该会导入一个 30 题的多项选择文档。看起来好像一切都已正确导入，然后刷新表单，您会发现缺少选项。代码在下面，我也有made a gist of it on github

  FormApp.getUi()

Answer 1

实际上我也遇到了同样的问题，我找到了一个 hacky 的解决方法。它的复杂度很高 O(n^2)，但它确实有效。

基本上，我会仔细检查每个问题的选择是否正确。

const items = [];
for(var i=0;i<questions.length;i++) {
    items.push(form.addMultipleChoiceItem());
}

for(var j=0;j<questions.length;j++) {
    for(var i=0;i<questions.length;i++) {
        var item = items[i];
        if(item.getChoices()[0].getValue() === "A") continue; // already set question with choices, ignore it 
        item.setPoints(points);

        if (data.answer_sheet) { item.setTitle("Question " + i) }

        var choices = [];

        for (var i=0; i < question.count; i++) {
            choices.push(item.createChoice(String.fromCharCode(65 + i), i+1 == question.correct));
        }

        item.setRequired(required);
        item.setChoices(choices);
    }
}

Answer 2

我的附加组件遇到了同样的问题，我想我设法修复了我的附加组件，我所做的是 - 我将 setChoices 移到了 setTitle 之后的任何其他属性之前。以前，我的代码与您的代码相似，我最后添加了 setChoices（在 setRequired 等之后）。

Google Form AppScript - Item choices disappear when viewing, however it's showing in editing view?

我不知道怎么解释，但经过几次测试后它似乎对我有用。

Answer 3

我遇到了同样的问题，但我解决了。服务器需要一些时间来创建项目。因此，让您的脚本等待项目完成。将此行放在项目创建任务之后。

SpreadsheetApp.flush();

Answer 4

有同样的问题。简单的修复。而不是这个：

  var form = FormApp.getActiveForm()
    const students = ['Han S.','Luke S.','Yoda']

    var pickYourName = form.addMultipleChoiceItem()
        // RISK OF EMPTY CHOICES: DON'T SET CHOICEVALUES LAST
        pickYourName.setTitle('Choose your name:')
        pickYourName.setChoiceValues(students)

只需调换操作顺序，将标题设置在最后即可，如下所示：

    var form = FormApp.getActiveForm()
    const students = ['Han S.','Luke S.','Yoda']

    var pickYourName = form.addMultipleChoiceItem()
        // HAD NO ISSUE DOING IT THIS WAY: CHOICES FIRST, THEN TITLE
        pickYourName.setChoiceValues(students)
        pickYourName.setTitle('Choose your name:')
