I'm trying to learn web development with CSS, HTML and JAVASCRIPT(i'm new to all of them) and I'm working on some whack-a-mole game code that was free to work with. I understood what the code does, but I'm not sure how to work with. I have an event listener on click for each mole, but I wanna do something if the mole isn't clicked and I don't know how to check that. I tried different methods, using boolean variables or trying to check if the click was outside the element, but none of them worked. I'm pretty sure I didn't used them right, so I would really appreciate some help or information. I'll leave here the JS code. Thanks so much!
const holes = document.querySelectorAll('.hole');
const scoreBoard = document.querySelector('.score');
const moles = document.querySelectorAll('.mole');
const mySound=document.getElementById("sound");
const joc=document.getElementsByClassName("game");
let lastHole;
let timeUp = false;
let score = 0;
function randomTime(min, max) {
return Math.round(Math.random() * (max - min) + min);
}
function randomHole(holes) {
const index = Math.floor(Math.random() * holes.length);
const hole = holes[index];
if (hole === lastHole) {
return randomHole(holes);
}
lastHole = hole;
return hole;
}
function peep() {
const time = randomTime(500, 1000);
const hole = randomHole(holes);
hole.classList.add('up');
setTimeout(() => {
hole.classList.remove('up');
if (!timeUp) {
peep();
}
}, time);
}
function startGame() {
scoreBoard.textContent = 0;
timeUp = false;
score = 0;
peep();
setTimeout(() => timeUp = true, 90000)
}
function wack(e) {
if (!e.isTrusted) return;
score = score + 100;
this.parentNode.classList.remove('up');
scoreBoard.textContent = score;
}
moles.forEach(mole => mole.addEventListener('click', wack));

You can add a click event to the documentElement and check its target. Consequently you could also remove your other click handlers while doing this and check for the class mole.
;document.documentElement.onclick = function(event){
//REM: Target element of the click
var tTarget = event.srcElement || event.target;
//REM: Check which element was targted.
if(tTarget.id === 'sample'){
alert('You clicked on #sample')
}
else{
alert('You clicked on "' + tTarget.tagName + '"')
}
};

How to Output chosen DIV elements that are stored in an array

I'm creating a card game where the user chooses 2 out of 3 cards. I then store those cards into an array and want to be able to print out the cards that were stored in the array with the actual image of the cards that the user chose.
I've tried looping through the array and then using innerHTML to push the results to a specific div but I keep getting "[object HTMLDivElement]". It also prints that out 3 times instead of 2 (since we are choosing 2 cards there should only be two elements to print out, I suspect the loop is running an extra time).
The below is the loop I have tried but I also am including a codepen for further clarity.
https://codepen.io/cramos2/pen/pMVjez
var holder = document.getElementById("cardResults");
for(var i=0; i < chosenCards.length; i++){
holder.innerHTML += "<p>" + chosenCards[i] + "</p><br>";
}
let chosenCards = new Array();
class tarot {
//constructor
constructor(cards) {
this.cardsArray = cards;
}
startReading() {
this.shuffleCards(this.cardsArray);
//call shuffle method
}
//Adds class "flipped" to the cards
flipCard(card, cards) {
if (this.canFlipCard(card)) {
if (chosenCards.length >= 2) {
console.log("removing1");
//from here
for (let card0 in cards) {
let list = card0.classList;
if (list) {
if (!list.contains('visible')) {
card0.removeEventListener('click', card0.fn);
}
}
}
} //to here
else if (!card.classList.contains('visible')) {
debugger;
card.classList.add('visible');
chosenCards.push(card);
console.log(chosenCards);
//this is where print out
var holder = document.getElementById("cardResults");
for (var i = 0; i < chosenCards.length; i++) {
holder.innerHTML += "<p>" + chosenCards[i] + "</p><br>";
}
card.removeEventListener('click', card.fn);
}
}
}
//Need a Shuffle method in here
shuffleCards(cardsArray) {
for (let i = cardsArray.length - 1; i > 0; i--) {
const randIndex = Math.floor(Math.random() * (i + 1));
[cardsArray[i], cardsArray[randIndex]] = [cardsArray[randIndex], cardsArray[i]];
}
cardsArray = cardsArray.map((card, index) => {
card.style.order = index;
});
}
//gets the card
getCardType(card) {
return card.getElementsByClassName('card-value')[0].src;
}
//returns card
canFlipCard(card) {
return card
}
}
//this will call the reading to start when page is loaded
if (document.readyState == 'loading') {
document.addEventListener('DOMContentLoaded', ready)
} else {
ready()
}
function ready() {
//declares card's' & sets it to the card class in HTML
let cards = Array.from(document.getElementsByClassName('card'));
//creates new instance of tarot class
let tarotReading = new tarot(cards);
let over = Array.from(document.getElementsByClassName('over'));
over.forEach(overlay => {
overlay.addEventListener('click', () => {
overlay.classList.remove('visible');
tarotReading.startReading();
});
});
//flips the cards
cards.forEach(card => {
card.addEventListener('click', card.fn = function clicked() {
tarotReading.flipCard(card, cards);
//remove cards that dont have visible tag
});
})
console.log(chosenCards[0]);
}

The expected result would be the flipped over card with the text (not the number of the card) that the user has chosen.

You could try something like this:
for(var i=0; i < chosenCards.length; i++){
holder.appendChild(chosenCards[i].cloneNode(true));
}

hover in css have does no effect when element is hoverd

So I made a bunch of divs stacked on each other, and I want each div to change its background color whenever its hover, but that's not what happens
When I hover an item its background color should change to green,
but it doesn't work even that I wrote div.oldiv:hover{background-color: #48FF0D;}
The problem is probably in CSS code.
Here is a snippet :
body{
background-color: #48FF0D;
}
#bigdiv {
height: 90%;
width: 100%;
}
.oldiv {
height: 0.390625%;
width: 100%;}
div.oldiv:hover{
background-color: #48FF0D;
}
#bigdiv2 {
height: 0;
width: 100%;
}
.btn {
border: none;
color: white;
padding: 14px 28px;
cursor: pointer;
}
.uptodown {
background-color: #e7e7e7;
color: black;
}
.uptodown:hover {
background: #ddd;
}
.l{
float: right;
}
<body>
<script>
var b = "",k = "",a,q,d;
for(a = 0;a<=256;a++){
d =" <div id=\"du\" class=\"oldiv\" style=\"background-color: rgb("+a+","+a+","+a+");\"></div>";
q =" <div id=\"du\" class=\"oldiv\" style=\"background-color:rgb("+(256-a)+","+(256-a)+","+(256-a)+");\"></div>";
b = b+"\n"+d;
k = k+"\n"+q;
}
window.onload = function (){
document.getElementById("bigdiv").innerHTML = b;
document.getElementById("bigdiv2").innerHTML = k;
}
function utd(a){
var bigdiv = document.getElementById("bigdiv");
var bigdiv2 = document.getElementById("bigdiv2");
if(a == 0){
bigdiv.style.height = "0";
bigdiv2.style.height= "90%";
}else{
bigdiv.style.height = "90%";
bigdiv2.style.height= "0";
}
}
</script>
<div id="bigdiv">
</div>
<div id="bigdiv2">
</div>
<div>
<button class="btn uptodown" onclick="utd(0)">white to black</button>
<button class="btn uptodown l" onclick="utd(1)">black to white</button>
</div>
</body>
Don't word about all the Javascript, its just to generate elements and adding them to HTML

I have no idea what the purpose of this code is, but I think I have fixed it..... Whatever it is :P
Your #bigdiv and #bigdiv2 percentage height were not working because the height of the document wasn't 100%. So I just added html, body {height:100%;} to fix that.
/* code added START */
html, body {
height:100%;
}
div.oldiv:hover {
background-color: #48FF0D!important;
}
/* code added END */
body{
background-color: #48FF0D;
}
#bigdiv {
height: 90%;
width: 100%;
}
.oldiv {
height: 0.390625%;
width: 100%;
}
/* div.oldiv:hover{background-color: #48FF0D;} */
#bigdiv2 {
height: 0;
width: 100%;
}
.btn {
border: none;
color: white;
padding: 14px 28px;
cursor: pointer;
}
.uptodown {
background-color: #e7e7e7;
color: black;
}
.uptodown:hover {
background: #ddd;
}
.l {
float: right;
}
<script>
var b = "",k = "",a,q,d;
for(a = 0;a<=256;a++){
d =" <div id=\"du\" class=\"oldiv\" style=\"background-color: rgb("+a+","+a+","+a+");\"></div>";
q =" <div id=\"du\" class=\"oldiv\" style=\"background-color:rgb("+(256-a)+","+(256-a)+","+(256-a)+");\"></div>";
b = b+"\n"+d;
k = k+"\n"+q;
}
function utd(a) {
var bigdiv = document.getElementById("bigdiv");
var bigdiv2 = document.getElementById("bigdiv2");
if(a == 0) {
bigdiv.style.height = "0";
bigdiv2.style.height= "90%";
} else {
bigdiv.style.height = "90%";
bigdiv2.style.height= "0";
}
}
</script>
<div id="bigdiv">

<script>document.write(k);</script>

Well, there is no use of Javascript here. I'm not able to understand what problem you're facing but refer here : https://www.w3schools.com/cssref/sel_hover.asp
CSS already has property of hover and can be used like element:hover {your properties inside like whatever event has to be happened on hover}. There is no need to use JS here. Hope this helps.
UPDATE:
I would also suggest you to follow good practice of writing JS code and CSS code in a separate file not in a HTML file.

Fill parent div with the image being hovered over

I am still fairly new to JS, and I am trying to replace the HTML of a div with a picture that is being moused over, and when the mouse leaves I want it to return to it's normal state. I thought that I did everything right but my code doesn't seem to be working. I've looked through stack overflow and I see a lot of jQuery solutions to my 'problem,' but I would like an answer in pure JavaScript (I'm trying to "maser" this first), along with an explanation so I can understand why the answer IS the answer. Thanks.
I'll try to explain myself (my code). I grabbed reference to the image holder, and I grabbed reference to the the images. I thought I made a function that looped through the array of images and added an event listener to whichever image ( image[i] ) was being moused over. Then, I added an event listener that is supposed to return the image holder to it's default state by inserting the original HTML. I just don't understand how to fix this.
var holder = document.getElementById('holder');
var images = document.getElementsByTagName('img');
var popImage = function () {
for (i = 0; i < images.length; i++) {
images[i].addEventListener('mouseover', = function () {
holder.innerHTML = images[i];
});
images[i].addEventListener('mouseout', function () {
holder.innerHTML =
'<div class='col-md-3 img-fluid' id='img1'><img src='photo1.jpg'></div>
<div class='col-md-3 img-fluid' id='img2'><img src='photo2.jpg'></div>
<div class='col-md-3 img-fluid' id='img3'><img src='photo3.2.jpg'></div>
<div class='col-md-3 img-fluid' id='img4'><img src='photo4.jpg'></div>'
});
};
};
popImage();

You said you are new to JS and just learning which is great but an important part of learning JS is learning when not to use it. As #Yoda said if this was for production you really should use CSS instead of JS.
Here is one way you could accomplish this with pure CSS
<style>
.img {
width: 100px;
height: 100px;
background: #bada55;
border: 2px solid #333;
float: left;
}
.holder:hover > .img {
opacity: 0;
}
.holder:hover > .img:hover {
opacity: 1;
}
</style>
<div class="holder">
<!-- Using div.img for simplicity, these whould be your <img/> tags -->
<div class="img">1</div>
<div class="img">2</div>
<div class="img">3</div>
<div class="img">4</div>
</div>
For the purpose of learning, here's how you'd do it in JS:
var holder = document.getElementById('holder');
var images = document.querySelectorAll('.img');
var filter = false;
function popImage () {
// Use for (var i = 0 . . .
// Instead of for (i = 0 . . .
// Because without var, i will be stored in the global scope
for (var i = 0; i < images.length; i++) {
(function (_i) {
images[_i].addEventListener('mouseover', function () {
holder.innerHTML = '';
// We can't set innerHTML to images[_i]
// because it's a DomNode not a string
holder.appendChild(images[_i]);
});
})(i);
}
holder.addEventListener('mouseout', function (e) {
if (e.target !== holder)
return;
holder.innerHTML = '';
// Again, use var j = 0 . . .
for (var j = 0; j < images.length; j++) {
holder.appendChild(images[j]);
}
});
}
popImage();
.img {
width: 100px;
height: 100px;
background: #bada55;
border: 2px solid #333;
display: inline-block;
}
#holder {
position: relative;
width: 100%;// So doesn't collape and trigger mouseout
height: 100px;
background: red;
padding: 20px 0;
}
<div id="holder">
<!-- Again, these would be your image tags -->
<div class="img">1</div>
<div class="img">2</div>
<div class="img">3</div>
<div class="img">4</div>
</div>

I had 10 mins before leaving work so I had a crack at this to see how I would do it and give you some ideas.
Here is my implementation (https://jsfiddle.net/hg7s1pyh/)
I guess the main thing here is that I've broken it down into lots of smaller parts, this makes solving problems far easier, each method is concerned with doing one thing only.
You will also note the use of classes to show and hide content rather than removing it entirely, this takes lots of the arduous work out of this feature.
function attachEvents() {
var images = getImages();
images.forEach(function(image) {
attachMouseOverEvent(image);
attachMouseLeaveEvent(image);
});
}
function attachMouseOverEvent(element) {
element.addEventListener('mouseover', function(e) {
var clonedImage = e.target.cloneNode();
addImageToPreview(clonedImage);
});
}
function attachMouseLeaveEvent(element) {
element.addEventListener('mouseleave', function(e) {
removeImageFromPreview();
});
}
function getImages() {
return document.querySelectorAll('.js-image');
}
function getImagePreviewElement() {
return document.querySelector('.js-image-box');
}
function addImageToPreview(imageElement) {
var previewElement = getImagePreviewElement();
previewElement.classList.add('previewing');
previewElement.appendChild(imageElement);
}
function removeImageFromPreview() {
var previewElement = getImagePreviewElement();
previewElement.classList.remove('previewing');
var image = previewElement.querySelector('.js-image');
image.remove();
}
attachEvents();

Show only a few users and hide others

Can anyone explain how to make a user list like as shown in the image below...
I'm making a project in Meteor and using Materialize for template and I want to display the list of assigned users. If there are more than a particular count(say 5) of users i want them to be displayed like on that image... I have tried googling this and haven't found anything useful. I also checked the Materialize website and found nothing useful. So if anyone has an idea please help share it.
Ok so this is the output html, in this case i only have one member but in real case I will have more:
<div class="row"> ==$0
<label class="active members_padding_card_view">Members</label>
<div class="toolBarUsers flex" style="float:right;">
<dic class="other-profile" style="background-color:#f06292;">
<span>B</span>
</div>
This is the .js code
Template.profile.helpers({
randomInitials: function () {
var chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
var nLetter = chars.charAt(Math.floor(Math.random()*chars.length));
var sLetter = chars.charAt(Math.floor(Math.random()*chars.length));
return nLetter + sLetter;
},
tagColor: function () {
var colors = ["#e57373","#f06292","#ba68c8","#9575cd","#7986cb","#64b5f6","#4fc3f7","#4dd0e1","#4db6ac","#81c784","#aed581","#dce775","#fff176","#ffd54f","#ffb74d","#ff8a65","#a1887f","#e0e0e0","#90a4ae"];
return colors[Math.floor(Math.random()*colors.length)];
},
randomAllowed : function(possible) {
var count = Math.floor((Math.random() * possible) + 1);
if(count == 1) {
return;
}
return "none";
},
membersList() {
const instance = Template.instance();
const cardDataId = new Mongo.ObjectID(instance.data.cardData._id.valueOf());
return CardDataMembers.find({lkp_card_data_fkeyi_ref: cardDataId});
},
memberData: function() {
// We use this helper inside the {{#each posts}} loop, so the context
// will be a post object. Thus, we can use this.xxxx from above memberList
return Meteor.users.findOne(this.lkp_user_fkeyi_ref);
},
showMembers() {
const instance = Template.instance();
const cardDataId = new Mongo.ObjectID(instance.data.cardData._id.valueOf());
let membersCount = CardDataMembers.find({lkp_card_data_fkeyi_ref: cardDataId}).count();
////console.log(membersCount);
if (membersCount > 0) {
$('.modal-trigger').leanModal();
return true;
} else {
return false;
}
},
});
Right now if I add a lot of users I get this:

This can be done in many ways, but I've used CSS Flexbox.
I've used two <div>s one contains single user circles having class .each-user that is expanding (for reference I've taken 6) and another contains the total number of users having class .total-users.
It's a bit confusing but if you look into my code below or see this Codepen you'll get to know everything.

}

}
/* Contains all circles (those without total value written on it) */
.each-user {
display: flex;

Hope this helps!

I've used jQuery. See this https://jsfiddle.net/q86x7mjh/26/
HTML:
<div class="user-list-container">
<div class="total-circle hidden"><span></span></div>
<div class="user-circle"><span>T</span></div>
<div class="user-circle"><span>C</span></div>
<div class="user-circle"><span>U</span></div>
<div class="user-circle"><span>M</span></div>
<div class="user-circle"><span>R</span></div>
<div class="user-circle"><span>Z</span></div>
<div class="user-circle"><span>N</span></div>
<div class="user-circle"><span>O</span></div>
<div class="user-circle"><span>M</span></div>
<div>
jQuery:
var items_to_show = 5;
if($('.user-circle').length > items_to_show){
var hide = $('.user-circle').length - items_to_show;
for(var i = 0; i < hide; i++){
$('.user-circle').eq(i).addClass('hidden');
}
$('.total-circle').removeClass('hidden');
$('.total-circle span').text('+' + hide);
}

So after quite some time I have solved the problem. I am posting my answer here for anyone that will in the future experience a similar issue...
Have a good day!
I have added the following lines of code to my template:
return CardDataMembers.find({lkp_card_data_fkeyi_ref: cardDataId},{sort: {createdAt: -1}, limit: 3});
diffMembers(){
const instance = Template.instance();
const cardDataId = new Mongo.ObjectID(instance.data.cardData._id.valueOf());
const limit = 3;
const allMembersOnCard = CardDataMembers.find({lkp_card_data_fkeyi_ref: cardDataId}).count();
let remainingMembers = allMembersOnCard - limit;
return remainingMembers;
},
And in the HTML included:
<div class="other-profile" style="background-color:#dedede;">
<span>+{{diffMembers}}</span>
</div>
