Google 脚本（表单）- 无法将数组转换为选择[]

Question

我已经研究了这个问题一段时间，但尚未找到合适的答案（大多数涉及切换到 setChoiceValues() 而不是解决 "Cannot convert Array to Choice[]" 问题与 setChoices([])）。

在尝试通过 Google 脚本生成表单部分和问题时，我运行遇到了无法让我的答案选择转到基于用户答案的特定页面的问题。这似乎是 setChoiceValues() 和 setChoices([]) 之间的区别，据我所知后者允许页面导航。

然而，当我尝试将我的新选择数组放入 setChoices([]) 时，我收到错误消息 "Cannot convert Array to Choice[]"。否则我的代码工作正常，但我需要使用 setChoices([]) （看起来）以获得我想要的页面导航。

如何将值循环到数组或其他容器中并使它们显示为 Choices[] 对象？我怎样才能做这样的事情？看起来应该比现在容易得多，但我看不到解决方案。

下面是导致问题的一段代码：

//Form - globally accessible 
var f = FormApp.openById(f_id);
//Date Iterator
var curr_date = 0;
//Time Iterator
var curr_time = 0;
//Array of Times
var Tchoices = [];
//Setting Time choices per date
while(curr_date < dates.length)
{
    Tchoices = [];
    curr_time = 0;
    //dates is an array of objects with both d's (single date) and t's 
    //    (array of times for that date)
    var d = dates[curr_date].d;
    var end_break = f.addPageBreakItem().setTitle("Times for " + d);
    var f_time = f.addMultipleChoiceItem().setTitle(d);
    while(curr_time < dates[curr_date].t.length)
    {               
        end_break = end_break.setGoToPage(FormApp.PageNavigationType.SUBMIT);
        Tchoices.push(f_time.createChoice(dates[curr_date].t[curr_time], end_break).getValue());
        curr_time++;
    } 
    f_time.setChoices([Tchoices]);
}

您的 MultipleChoise 对象的构建存在一些小问题：

  //Form - globally accessible 
  var f = FormApp.openById('someID');
  //Date Iterator
  var curr_date = 0;
  //Time Iterator
  var curr_time = 0;
  //Array of Times
  var Tchoices = [];
  //Setting Time choices per date
  while(curr_date < dates.length)
  {
      Tchoices = [];
      curr_time = 0;
      //dates is an array of objects with both d's (single date) and t's 
      //    (array of times for that date)
      var d = dates[curr_date].d;
      var end_break = f.addPageBreakItem().setTitle("Times for " + d);
      var f_time = f.addMultipleChoiceItem();
      f.addMultipleChoiceItem().setTitle(d);
      while(curr_time < dates[curr_date].t.length)   //verify this while not sure what you have inside your dates array
      {               
          end_break = end_break.setGoToPage(FormApp.PageNavigationType.SUBMIT);
          Tchoices.push(f_time.createChoice(dates[curr_date].t[curr_time])); //You cannot add a pagebreak inside the elements of a choiseItem array
          curr_time++;
      } 
      Logger.log(Tchoices);
      f_time.setChoices(Tchoices);
  }

检查循环中日期[curr_date].t.length 的值我不确定您是如何构建数组的。您不能在 choiseItem 数组的元素内添加分页符
