Получение Qualtrics с несколькими вариантами выбора для динамического населения из массива JavaScript ⇐ Javascript

[Anonymous]

Я провожу совместный эксперимент с использованием JavaScript в Qualtrics, в котором участвуют респонденты, которые должны выбирать между двумя политическими кандидатами.

Код: Выделить всё

    setTimeout(function () {
document.querySelectorAll(".QuestionText").forEach(q => {
q.innerHTML = q.innerHTML
.replace(/\[PROFILE1\]/g, profile1Name)
.replace(/\[PROFILE2\]/g, profile2Name);
});
}, 500);
< /code>
Когда я вставляю [profile1] и [profile1] в текст вопроса для вопроса с множественным выбором в Qualtrics, они правильно заполняют имена профилей, например, "Джон" и "Майкл". Однако, когда я сами вкладываю эти теги в фактические параметры ответа, они пусты.  < /P>
Кто -нибудь знает, как решить это?Qualtrics.SurveyEngine.addOnload(function() {

// Arrays containing all attribute levels:
var EducationArray = ["High school diploma", "Bachelor's degree"];
var GenderArray = ["Male","Female"]; // Gender is still randomized normally
var RaceArray = ["White", "Black", "Hispanic"];

// Political Experience Array
var PoliticalExperienceArray = ["None", "State legislator", "Congress"];

// Name arrays
var MaleNames = ["James", "Michael", "William", "John", "David"];
var FemaleNames = ["Susan", "Jennifer", "Emily", "Olivia", "Barbara"];

// Fisher-Yates shuffle function
function shuffle(array) {
for (var i = array.length - 1; i > 0; i--) {
var j = Math.floor(Math.random() * (i + 1));
[array[i], array[j]] = [array[j], array[i]]; // Swap elements
}
return array;
}

// Function to shuffle and return a single element
function shuffle_one(theArray) {
return shuffle(theArray.slice())[0]; // Avoid modifying original array
}

// Function to select two different names from respective lists
function getRandomNames(gender1, gender2) {
let name1, name2;
if (gender1 === "Male") {
let shuffledMales = shuffle(MaleNames);
name1 = shuffledMales[0];
name2 = gender2 === "Male" ? shuffledMales[1] : shuffle_one(FemaleNames);
} else {
let shuffledFemales = shuffle(FemaleNames);
name1 = shuffledFemales[0];
name2 = gender2 === "Female" ? shuffledFemales[1] : shuffle_one(MaleNames);
}
return [name1, name2];
}

// Generate profile pairs
function genprof() {
var gender1 = shuffle_one(GenderArray);

var attributes = [

{ label: "Political Experience", value1: shuffle_one(PoliticalExperienceArray), value2: shuffle_one(PoliticalExperienceArray) },

];

// Ensure "Congress" is gendered appropriately
attributes.forEach(attr => {
if (attr.label === "Political Experience") {
if (attr.value1 === "Congress") {
attr.value1 = gender1 === "Male" ? "Congressman" : "Congresswoman";

attr.value2 = gender2 === "Male" ? "Congressman" : "Congresswoman";
}
}

// Retrieve attribute order if already set, otherwise shuffle and set it

// Increment round number for next iteration
let nextRound = currentRound + 1;
Qualtrics.SurveyEngine.setEmbeddedData("current_round", nextRound);

// Update table headers with names

Я относительно новичок в JavaScript, поэтому очень ценил любую помощь, спасибо.
