use var i = 0 instead of int i = 0

Simple Quiz Game JavaScript

I'm just learning now. Can you please help me, why am I not getting the correct output. This is my code:
//ask questions
var quiz = [
["When is Bulgaria established?", 681],
["What year was it before 16 years?", 2000],
["When does WWII ends?", 1945]
];
//variables
var answer = [];
var correct = [];
var wrong = [];
var correctAns = 0;
var wrongAns = 0;
var oList = "<ol>";
//function to print the result in ordered list
function printResult(result){
for(var j = 0; j < result.length; j++){
oList += "<li>" + result[i] + "</li>";
}
oList += "</ol>";
return oList;
}
function print(message) {
document.getElementById('output').innerHTML = message;
}
//looping, adding correct and wrong answeres
for(var i = 0; i < 3; i++) {
answer[i] = prompt(quiz[i][0]);
if(parseInt(answer[i]) == quiz[i][1]){
correct.push(quiz[i][0]);
correctAns++;
} else {
wrong.push(quiz[i][0]);
wrongAns++;
}
}
//print logic
if(correct.length < 1 || correct == undefined){
print("You did not guess any of the quiestions!");
} else if (correct.length >= 1){
print("You have guessed " + correctAns + " questions.");
print(printResult(correct));
print("You have " + wrongAns + " wrong answeres.");
if(wrongAns > 0){
print(printResult(wrong));
}
}
I have watched this code over and over again and I still can't understand why am I getting undefined as a result. In the debugger, after the loop I check my vars and everything seems ok.

In your printResult function you are using var i instead of j,
Also you better use innerHtml+=message;
//ask questions
var quiz = [
["When is Bulgaria established?", 681],
["What year was it before 16 years?", 2000],
["When does WWII ends?", 1945]
];
//variables
var answer = [];
var correct = [];
var wrong = [];
var correctAns = 0;
var wrongAns = 0;
//function to print the result in ordered list
function printResult(result){
//HERE:
var oList = "<ol>";
for(var j = 0; j < result.length; j++){
oList += "<li>" + result[j] + "</li>";
}
oList += "</ol>";
return oList;
}
function print(message) {
document.getElementById('output').innerHTML += message;
}
//looping, adding correct and wrong answeres
for(var i = 0; i < 3; i++) {
answer[i] = prompt(quiz[i][0]);
if(parseInt(answer[i]) == quiz[i][1]){
correct.push(quiz[i][0]);
correctAns++;
} else {
wrong.push(quiz[i][0]);
wrongAns++;
}
}
//print logic
if(correct.length < 1 || correct == undefined){
print("You did not guess any of the quiestions!");
} else if (correct.length >= 1){
print("You have guessed " + correctAns + " questions.");
print(printResult(correct));
print("You have " + wrongAns + " wrong answeres.");
if(wrongAns > 0){
print(printResult(wrong));
}
}
<div id="output">
</div>

Basically you have three problems.
reuse of oList, the variable should be inside declared and used only in printResult.
Inside of printResult, use of i where j have been used and
At print, you replace the actual content with new content.
Just a small hint with variable names for counting. It is good practise to start always with i instead of j and go on with the letters in the alphabet.
var quiz = [["When is Bulgaria established?", 681], ["What year was it before 16 years?", 2000], ["When does WWII ends?", 1945]],
answer = [],
correct = [],
wrong = [],
correctAns = 0,
wrongAns = 0;
//function to print the result in ordered list
function printResult(result) {
var oList = "<ol>"; // !!! move variable inside of the function
for (var j = 0; j < result.length; j++) {
oList += "<li>" + result[j] + "</li>"; // !!! use j indstead if i
}
oList += "</ol>";
return oList;
}
function print(message) {
document.getElementById('output').innerHTML += message; // !!! append message
}
//looping, adding correct and wrong answeres
for (var i = 0; i < 3; i++) {
answer[i] = prompt(quiz[i][0]);
if (parseInt(answer[i]) == quiz[i][1]) {
correct.push(quiz[i][0]);
correctAns++;
} else {
wrong.push(quiz[i][0]);
wrongAns++;
}
}
//print logic
if (correct.length < 1 || correct == undefined) {
print("You did not guess any of the quiestions!");
} else if (correct.length >= 1) {
print("You have guessed " + correctAns + " questions.");
print(printResult(correct));
print("You have " + wrongAns + " wrong answeres.");
if (wrongAns > 0) {
print(printResult(wrong));
}
}

Your main mistake is using i intead of j:
for(var j = 0; j < result.length; j++){
oList += "<li>" + result[j] + "</li>";// here was i before
}

Keep the clicked objects in an array in javascript

I made a puzzle game in javascript. I have made objects to keep some attributes relevant to the each pazzle squares. I want to get the object id which is relevant to the onclick.(not the div id). How to get the specific object id relevant to the clicked div?
window.onload = function() {
createDivs();
objects();
random();
onclickeventHanlder(event);
};
var getId;
var x = 3;
var counting = 0;
var tileSize = 600 / x;
var array2 = [];
var object = [];
function createDivs() {
var count = 0;
for (var i = 0; i < x; i++) {
for (var j = 0; j < x; j++) {
var id = i + "" + j;
var element = document.createElement('div');
element.setAttribute("class", "pieces");
element.setAttribute("id", id);
element.style.width = 600 / x + "px";
element.style.height = 600 / x + "px";
element.style.margin = "0px auto";
element.style.overflow = "hidden";
element.setAttribute("onclick", "onclickeventHanlder(this)");
if (count > 0) { // to break row-wise
if (i == count && j == 0) {
element.style.clear = "both";
}
}
element.style.float = "left";
document.getElementById('puzzle-body').appendChild(element);

for (var j = 0; j < x; j++) {
var objName = new Object();
objName.position = -(j * tileSize) + "px" + " " + -(i * tileSize) + "px";
objName.divID = document.getElementById(i + "" + j);
objName.id = count;
if(count<x*x-1){

making groups with random names in it in javascript

I am new to coding Javascript. I am trying to to shuffle list of names inputted on a textarea. The user selects the number of groups desired, and shuffle on click, then show the divided groups as output result. Below is my code but it is not working as it should be, pls help!
<script>
function ArrayToGroups(source, groups){
var groupList = [];
groupSize = Math.ceil(source.length/groups);
var queue = source;
for(var r = 0; r < groups; r++){
groupList.push(queue.splice(0,groupSize));
}
return groupList;
}
function textSpliter(splitText){
var textInput = document.getElementById("inputText").value;
var splitText = textInput.split(',');
var newList = [];
for(x = 0; x <= splitText.length; x++) {
var random = Math.floor(Math.random() * splitText.length);
var p = splitText[random];
newList.push(p);
splitText.splice(p,groupList);
}
for(var i = 0; i < newList.length; i++){
var s = newList[i];
document.getElementById('resInput').value += s + "\n" ;
}
return splitText;
}
</script>
Below is my input and output textareas
</head>
<body>
<form>
<textarea id="inputText" placeholder="text" rows="10" cols="40"></textarea>
<input type="number" name="number" max="6" value="1" id="groupNumber">
<textarea id="resInput" placeholder="text" rows="10" cols="40"></textarea>
<input type="button" name="Shuffle" value="shuffle" onclick="textSpliter()">
</form>
</body>
</html>

function shuffle() {
// Get list
// Example: element1, element 2, ele ment 3, ...
var list = document.getElementById("inputText").value.replace(/\s*,\s*/g, ",").split(",");
// Get number of groups
var n = parseInt(document.getElementById("groupNumber").value);
// Calculate number of elements per group
var m = Math.floor(list.length / n);
// Enought elements
if (n * m == list.length) {
// Create groups
var groups = new Array();
for (i = 0; i < n; i++) {
groups[i] = new Array();
for (j = 0; j < m; j++) {
// Random
rand = Math.floor(Math.random() * list.length);
// Add element to group
groups[i][j] = list[rand];
// Remove element to list
list.splice(rand, 1);
}
}
// Output
var text = "";
for (i = 0; i < n; i++) {
text += "Group " + (i + 1) + ": ";
for (j = 0; j < m; j++) {
if (j != 0) { text += ", "; }
text += groups[i][j];
}
text += "\n";
}
document.getElementById("resInput").value = text;
} else {
alert("Add more elements");
}
}

I rewrote your code. It's pretty self-explanatory.
FIDDLE
function textSpliter() {
var input = document.getElementById("inputText").value;
var names = input.split(",");
var groupSize = document.getElementById("groupNumber").value;
var groupCount = Math.ceil(names.length / groupSize);
var groups = [];
for (var i = 0; i < groupCount; i++) {
var group = [];
for (var j = 0; j < groupSize; j++) {
var random = Math.floor(Math.random() * names.length);
var name = names[random];
if (name != undefined) {
group.push(name);
names.splice(names.indexOf(name), 1);
}
}
group.sort();
groups.push(group);
}
printGroups(groups);
}
function printGroups(group) {
var output = document.getElementById("resInput");
output.value = "";
for (var i = 0; i < group.length; i++) {
var currentGroup = "";
for (var j = 0; j < group[i].length; j++) {
currentGroup = group[i].join(",");
}
output.value += currentGroup + "\r";
}
}

var groups = [...Array(groupCount)].map(() => Array());
var i = 0
while (names.length > 0) {
var m = Math.floor(Math.random() * names.length);
groups[i].push(names[m]);
names.splice(m, 1);

In the above code, that is not complete, but which implements quine Mccluskey algorithm. There is a problem while it is debugged.
If a breakpoint is inserted at gFormula.reducetoPrimeImplicants(); the debugger does not go into that function. This is the last function called in the code until now. But, it does go to start(), which is the first function.
There is some problem in reducetoPrimeImplicants(); function because it also gives ERROR in internet explorer.
I am not able to figure out the error. If I remove reducetoPrimeImplicants(); function from the code the works fine.
Please, can somebody tell me why the debugger does not enter reducetoPrimeImplicants();.
I am using the Firebug debugger.
Thanks in advance.

The last function in your page combine() is missing a closing brace.
If you don't mind, a suggestion: Please use http://jsbeautifier.org/ or some similar tool to indent your code better.

Your For loop has two starting braces.
for (var i = 0; i < this.varVals.length; i++) {
{
So remove one. This should solve your problem.
