How to remove final html screen at the end of the experiment? cognition.run

[davidebottari]

Hi all,
We have an issue with each experiment we run on cognition.run
Probably this a very stupid issue! :)
At the end of the experiment, we would like a blank screen and not an HTML one.
Any can help us with how we can do this?
I attach below the code of one of the experiments (based on the example tasks provided in jsPsych).
Thanks in advance!!
Best,
Davide

var jsPsych = initJsPsych({
on_finish: function() {
jsPsych.data.displayData();
}
});

/* experiment parameters */
var reps_per_trial_type = 4;

/* Code */
var Code = {

type: jsPsychSurveyText,
button_label: ['Continua'],
questions: [
{prompt: 'Inserisci il Codice Alfanumerico Personale già usato in fase di accesso alla survey.', required: true}
]
};

/*set up welcome block*/
var welcome = {
  type: jsPsychHtmlKeyboardResponse,
  stimulus: "Ti diamo il benvenuto all’esperimento! Premi un tasto qualsiasi per poter iniziare."
};

/*set up instructions block*/
var instructions = {
  type: jsPsychHtmlKeyboardResponse,
  stimulus: "<p  align=left>In questo compito, vedrai sullo schermo cinque frecce, così come mostrato nell'esempio seguente</p>"+
    "<img src='img/inc1.png'></img>"+
    "<p align=left>Dovrai indicare la direzione della freccia centrale. Fornirai le tue risposte a questo compito utilizzando la tastiera del tuo PC. Premi il tasto freccia sinistra se la freccia centrale sta puntando a sinistra (<).  Premi il tasto freccia destra se la freccia centrale sta puntando a destra (>). Premi qualsiasi tasto per iniziare. </p>",
  post_trial_gap: 1000
};

/*defining stimuli*/
var test_stimuli = [
  {
    stimulus: "img/con1.png",
    data: { stim_type: 'congruent', direction: 'left'}
  },
  {
    stimulus: "img/con2.png",
    data: { stim_type: 'congruent', direction: 'right'}
  },
  {
    stimulus: "img/inc1.png",
    data: { stim_type: 'incongruent', direction: 'right'}
  },
  {
    stimulus: "img/inc2.png",
    data: { stim_type: 'incongruent', direction: 'left'}
  }
];

/* defining test timeline */
var test = {
  timeline: [{
    type: jsPsychImageKeyboardResponse,
    choices: ['ArrowLeft', 'ArrowRight'],
    trial_duration: 1500,
    stimulus: jsPsych.timelineVariable('stimulus'),
    data: jsPsych.timelineVariable('data'),
    on_finish: function(data) {
      var correct = false;
      if (data.direction == 'left' && jsPsych.pluginAPI.compareKeys(data.response, 'ArrowLeft') && data.rt > -1) {
        correct = true;
      } else if (data.direction == 'right' && jsPsych.pluginAPI.compareKeys(data.response, 'ArrowRight') && data.rt > -1) {
        correct = true;
      }
      data.correct = correct;
    },
    post_trial_gap: function() {
        return Math.floor(Math.random() * 1500) + 500;
    }
  }],
  timeline_variables: test_stimuli,
  sample: {type: 'fixed-repetitions', size: reps_per_trial_type}
};

// manually preload images due to presenting them with timeline variables
var images = ["img/con1.png","img/con2.png","img/inc1.png","img/inc2.png"];
var preload = {
  type: jsPsychPreload,
  images: images
};

/*set up experiment structure*/
var timeline = [];
timeline.push(preload);
timeline.push(Code);
timeline.push(welcome);
timeline.push(instructions);
timeline.push(test);

/*start experiment*/
jsPsych.run(timeline);

Hi @davidebottari,

This is probably a question best aimed at the cognition.run team if the site is adding a default screen at the end of the experiment.
