HTML Javascript Self-assessment quiz/questionnaire
Question
Hi so i got a very basic JavaScript HTML quiz working, however what i want to end up with is an assessment type quiz that has lets say 15 questions based on 3 categories (eg Alcoholism, depression, drug abuse) eg
How often to you drink alcohol? - All the time - Occasionally - Never
the player answers all 15 questions and at the end depending on how they answered the questions they get assigned a category eg your category is Drug Abuse etc.
I'm thinking that maybe each category has its own counter and a value is applied to each of the possible answers eg All the time gives a score of 3, occasionally scores a 2 etc. As the player answers the questions, the values get stored in the corresponding category and at the end the scores for each category are added up and the category with the highest score gets assigned to the player?
Any help with this would be appreciated :)
HTML:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h2 id="test_status"></h2>
<div id="test"></div>
</body>
</html>
CSS:
<style>
div#test {
border:#000 1px solid;
padding: 10px 40px 40px 40px;
}
</style>
JS:
<script>
var pos = 0, test, test_status, question, choice, choices, chA, chB, chC, correct = 0;
var questions = [
["How often do you drink?", "All the time", "Often", "Never", "B"],
["Do you ever feel sad for no reason?", "All the time", "Often", "Never", "C"],
["Have you ever tried drugs", "All the time", "Often", "Never", "C"],
["Do you feel uneasy around people", "All the time", "Often", "Never", "C"]
];
function _(x) {
return document.getElementById(x);
}
function renderQuestion () {
test = _("test");
if(pos >= questions.length) {
test.innerHTML = "<h2>Your Category is </h2>";
_("test_status").innerHTML = "Test Completed";
pos = 0;
correct = 0;
return false;
}
_("test_status").innerHTML = "Question "+(pos+1)+" of"+questions.length;
question = questions[pos] [0];
chA = questions[pos] [1];
chB = questions[pos] [2];
chC = questions[pos] [3];
test.innerHTML = "<h3>"+question+"</h3>";
test.innerHTML += "<input type='radio' name='choices' value='A'> "+chA+"<br>";

}
function checkAnswer() {

The executable Javascript snippet its generated by TypeScript (a public GIT repository is available on this bucket ), The quiz its organized by arguments and categories; below you can see the UML diagram.
var __extends = this.__extends || function (d, b) { for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p]; function __() { this.constructor = d; } __.prototype = b.prototype; d.prototype = new __(); }; var Categories; (function (Categories) { var QuestionCategory = (function () { function QuestionCategory(value) { this.Value = value; } return QuestionCategory; })(); Categories.QuestionCategory = QuestionCategory; var AQuestionCategory = (function (_super) { __extends(AQuestionCategory, _super); function AQuestionCategory() { _super.call(this, 1); } return AQuestionCategory; })(QuestionCategory); Categories.AQuestionCategory = AQuestionCategory; var BQuestionCategory = (function (_super) { __extends(BQuestionCategory, _super); function BQuestionCategory() { _super.call(this, 2); } return BQuestionCategory; })(QuestionCategory); Categories.BQuestionCategory = BQuestionCategory;

this quiz maker produces a very simple set of HTML and it's obvious where the total calculation is in order to change it.
You can simply add the numbers of questions relating to each answer, then compare to say which is largest and display the result. It gives you a choice of having radio buttons in a list for each question, or several on one line.
All the questions will display on a single page, rather than having to press Next each time which can be annoying for people doing the quiz. No CSS is needed and hardly any javascript.
Example code for a self-scoring quiz with 1 question of each type (drop-down box, short answer, multiple answers etc). The generator tool in the link above will create something similar, it's pure HTML and javascript with no external scripts to load, no jquery or dependencies.
