End experiment based on a survey response

[MyriamM16]

Hi,

I’m trying to create an eligibility and socio-demographic information form at the beginning of my task. To do so, I have 12 questions, each of which is a different and separate variable (since I need multiple types of survey responses: survey-multi-select, survey-text, survey multi-choice).

All the questions concerning the eligibility are of the “survey multi-select” type with two choices of answer, which are “yes” or “no”. So far so good. However, I would like to include a function to end immediately the experiment if a participant checks “no” (meaning he doesn't encounter this eligibility criterion).

I saw that there is a function allowing to end the experiment if a particular keyboard is pressed. For example,

on_finish: function (data) {
if (data.key_press == 78) {
jsPsych.endExperiment ('The experiment was ended by pressing N.');

However, I was wondering if it is possible to end the experiment based on a response in a survey (in my case, when the participant checks “no” in the survey-multi-select) instead of a keyboard pressed?

Thank you in advance,
Myriam

I found a solution by using the "html-button-response" plugin (with 2 buttons: "yes" or "no") and the following function:

on_finish: function (data) {
if (data.button_pressed == 0) {
jsPsych.endExperiment ('The experiment was ended by answering no.');

Thank you very much!!
