add item in google form

[cru...@itcgoriani.istruzioneer.it]

Hello everyone,

In a Google form ,that contains already 3 questions, I have to add a question before the first one after the third answer.

I have written the script that runs after each answer, but how can I choose where to add the question?

This is the code that I write:

var NumAnswer = 2; 

function onOpen() {

  var ui = FormApp.getUi();

  ui.createAddonMenu().addItem('Set Trigger', 'SetTrigger').addToUi();

}

function AddQuestion() {

  var form = FormApp.getActiveForm();

 

  var responses = form.getResponses();

 

  if (!responses) {

    return; 

  }

  if (responses.length > (NumAnswer -1)) {

    

    'ADD CODE

    '........

    '.........

  }

  

}

function SetTrigger() {

  

  

  var props = PropertiesService.getScriptProperties();

  if (props.getProperty('existstrigger')) {

    return;  

  }

      

  var triggers = ScriptApp.getProjectTriggers();

  if (triggers.length > 0) {

    for (i = 0; i < triggers.length; i ++) {

      if (triggers[i].getHandlerFunction() == 'addQuestion') {

        props.setProperty('existstrigger', true);

      }

    }

  }

  

  if (triggers.length == 0 || !(props.getProperty('existstrigger'))) {

    ScriptApp.newTrigger('addQuestion')

    .forForm(FormApp.getActiveForm())

    .onFormSubmit()

    .create();

    props.setProperty('existstrigger', true);

  }

}

thanks!

To be sure I understand correctly, you want to insert a 4th question, at the beginning of the form, after three people have submitted the form? You want a 4th question for the 4th person put at the beginning of the form?

If the above is true, I think you can simply use the form.moveItem() method. Something like this (untested) should do the job:

function AddQuestion() {

  var form = FormApp.getActiveForm();

 

  var responses = form.getResponses();

  

  if (!responses) {

    return; 

  }

  if (responses.length > (NumAnswer -1)) {

      //var newQuestion = your code to create a new question; example:

      var newQuestion = form.addTextItem();

        newQuestion.setTitle('What is your name?');

    //get the itemId of your new question

      var newQuestionId = newQuestion.getId();

    //move the new question to the first index of all items

      form.moveItem(newQuestionId, 0);

  }

}
