Trying to make the clock function on click

And thanks for stopping by.
I've been trying to add a feature, or function, to a project that I'm working on, but I just can't wrap my head around it.
When my project loads I want the user to activate the time as soon as they move, or click, one of the orbs -- not as soon as the project loads. I know there's an onClick or click event, but I'm having trouble implementing it on the js code. I've gone as far as commenting-out or "greying" entire functions to test things out.
Here's some of the time code:
function clockStart() {
numberOfSecs = setInterval(function () {
seconds.text(`${second}`)
second = second + 1
}, 1000);
}
function rewindSec(seconds) {
if (seconds) {
clearInterval(seconds);
}
}
gameStart();
// GAMES BEGIN!!!
function gameStart() {
var cards = shuffle(listOfCards);
deckOfCards.empty();
match = 0;
Moves = 0;
moveNum.text("0");
ratingStars.removeClass("fa-angry").addClass("fa-star");
for (var i = 0; i < cards.length; i++) {
deckOfCards.append($('<li class="card"><i class="fab fa-' + cards[i] + '"></i></li>'))
}
sourceCard();
rewindSec(numberOfSecs);
second = 0;
seconds.text(`${second}`)
clockStart();
};
Here's a link to the project that I'm talking about:

If someone can help me out with this, a thousand thank yous will come your way.
Thanks!

You can Change the event of starting the clock at another position
First remove the clockStart() function from the gameStart() method
seconds.text(`${second}`)
//clockStart();
if have added an Extra variable to detect if the clock is started or not
var isClockStarted=false;
The following code will start the timer when a card is clicked:
var sourceCard = function () {
deckOfCards.find(".card").bind("click", function () {
if(!isClockStarted)
clockStart();
The Bellow Code will check if the timer is started or not.
function clockStart() {
if(!isClockStarted){
isClockStarted=true;
numberOfSecs = setInterval(function () {
seconds.text(`${second}`)
second = second + 1
}, 1000);
}
}
I have found that you are not stopping the timer even after the game finishes
If canceled a game it starts timer again //toCheck

How do you integrate an incrementing variable into a paragraph

I am trying to make an idle game rather like candy box. I will have a number at the side of the page which rises by one every second. However, the code shown below does not seem to be working. Could anyone tell me why it is not working; how to fix it and where they got their info from. Thank you in advance.
<script type="text/javascript">
var i = 0;
function increment(){
i++;
document.getElementById('money').innerHTML = i;
}
setInterval(increment(), 1000);
</script>
<h2><u>The best game of the century</u></h2>
<p>you have £<span id="money"></span>.</p>
</body>
</html>

You have two issues:
You are calling your script before the DOM is rendered, so at the point the script runs, there is no element with ID of money.
In your setInterval call, you only need the function name (increment) without the parentheses. Including the parentheses (as increment()) only calls the function at that specific moment, rather than referencing it to be called at each interval. (See the Microsoft page on setInterval for more detailed information.)
See this code:
<h2><u>The best game of the century</u></h2>
<p>you have £<span id="money"></span>.</p>
<script type="text/javascript">
var i = 0;
function increment() {
i++;
document.getElementById('money').innerHTML = i;
}
setInterval(increment, 1000);
</script>

change setInterval(increment(), 1000); to setInterval(increment, 1000);
Its not working because as per document https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setInterval
it takes a function reference to be executed.. but calling the function increment() like this will only execute once and the return of that function will be used which will be null and not intended hope this clears it
var i = 0;
function increment(){
//console.log(i);
i++;
document.getElementById('money').innerHTML = i;
}
setInterval(increment, 1000);
<h2><u>The best game of the century</u></h2>
<p>you have £<span id="money"></span>.</p>

Javascript if statements in displaying images

Hey i am currently trying to get a program running in javascript i want the program to display the 4 images one after each other with the single press of a button and then after the 4 images have cycled through i want them to stop cycling and i cant seem to do it this is my code i currently have:
<html>
<head>
<script>
var images = ["image1.png","image2.png","image3.png","image4.png"];
var imagenum = 0;
var timer;
function imageCycle()
{
if(++imagenum == 4)
imagenum = 0;
document.image.src = images[imagenum];
timer = setTimeout("imageCycle()",1000);
}
</script>
</head>
<body>
<img src="image1.png" name="image" width=800 height=600>
<form>
<input type="button" value="images" name="cycle images" onclick="imageCycle()">
</form>
</body>
</html>
any help is appreciated many thanks!

In your code you continue to schedule the function, that's why the images continue to rotate.
If you want to stop at the forth image displayed, you have to put the setTimeout line in an else statement.
if (++imagenum == 4) {
imagenum = 0;
} else {
document.image.src = images[imagenum];
timer = setTimeout("imageCycle()",1000);
}
Another point, that other users notice and I just report here in my answer.
You use the string:
imageCycle()
as the first argument of setTimeout, insted you should use just the function name.
timer = setTimeout(imageCycle, 1000);

script to detect adblock isn't working

Can someone please help me with this script? It is to detect adblock. I have <script src="/js/ads.js"></script> in the head (a empty ads.js in the folder). Adblock will block this from loading thus not being on the page. Then I have the code below that will detect if the script is loaded or not. For some reason it is not working properly and still displays images. I had someone write the script below as well for it to check for ads 3 times with a 1 second interval but it seems to check infinitely 3 times at once. Can someone please help me work this properly? And also if it detects that it does load properly it won't keep pasting images into the div?
<script>
$(document).ready(function () {
var count = 3;
for (var i = 0; i < count; i++) {
setInterval(function () {
if (window.canRunAds === undefined) {
$('#StEQBidTjU').prepend('<img src="/miscimg/mZKoARJXcF.jpg" id="PtZZtkYjaR" />')
$('#AbHPbbbxyl').prepend('<img src="/miscimg/6hZ4nqcBZd.jpg" id="PLyCMzOHpx" />');
}
}, 1000);
}
});
</script>

You need to keep track of the count in each interval, and clear it once it's ran 3 times.
$(document).ready(function () {
var count = 3,
interval = setInterval(function () {
if (--count < 0) {
clearInterval(interval);
}
if (window.canRunAds === undefined) {
$('#StEQBidTjU').prepend('<img src="/miscimg/mZKoARJXcF.jpg" id="PtZZtkYjaR" />')
$('#AbHPbbbxyl').prepend('<img src="/miscimg/6hZ4nqcBZd.jpg" id="PLyCMzOHpx" />');
}
}, 1000);
});

Now you don't even need to do all these to detect AdBlock users, You can achieve this using a simple JS script called ABDetector
Here's how to use it:
- Download/Clone the project, upload the file abDetector.min.js
- Put this in your <head>:
<script type="text/javascript" src="abDetector.min.js"></script>
- Use this wherever you want to display a message to AdBlock users:
<div id="ab-message" style="display: none">Your message here!</div>
Then you're done. Check out the project on Github.

Javascript jquery fade-in/fadeout loop, how to use timer?

New to javascript and such, trying to create a loop for fading logos using jquery.
I've got it cycling through them just fine. But i tried to make the loop continuous; so that when it reached the last logo it went back to the beginning, by resetting my for-counter to 0 every time it reached the last logo. This resulted in an infinite loop i think that crashed my browser. So i did a quick google and discovered the window.setInterval(...) timer function.
My problem is, now that firing the looping code relies on timing, i can't figure out how to calculate the interval time. For reference here's the code that fades the logos in and out (before trying to loop it):
$(document).ready(function (){
var fadeDuration = 1000;
var timeBetweenFade = 2000;
var totalTimePerChange = fadeDuration + timeBetweenFade;
var totalLogos = $('.logo').length;
var currentLogo;
var i;
for(i = 0; i < totalLogos; i++)
{
currentLogo = "#img" + i;
if(i == 0){
$(currentLogo).fadeIn(fadeDuration).delay(timeBetweenFade).fadeOut(fadeDuration);
}
else{ //general case
$(currentLogo).delay(totalTimePerChange * i).fadeIn(fadeDuration).delay(timeBetweenFade).fadeOut(fadeDuration);
}
}
});
I tried to get the time a complete loop took in a couple of ways:
$(document).ready(function (){
//..declarations..
window.setInterval( function() {
//..FOR LOOP HERE..
}, i*(fadeDuration + timeBetweenFade + fadeDuration));
});
//I also tried..
$(document).ready(function (){
//..declarations..
var timeTakenToLoop;
var startLoopTime;
window.setInterval( function() {
startLoopTime = new Date().getTime();
//...FOR LOOP HERE..
timeTakenToLoop = new Date().getTime() - startLoopTime;
}, timeTakenToLoop);
});
But in both cases I get logos starting to overlap as the function calls timing is wrong. Could someone with a bit more experience suggest what the best approach would be?
Oh and just in case anyone needs it to understand the javascript, here's the html to match..
<div id="img0" class="logo">
<img src="{% static "CSS/Images/phone_icon.gif" %}"/>
</div>
<div id="img1" class="logo">
<img src="{% static "CSS/Images/email_icon.gif" %}"/>
</div>
<div id="img2" class="logo">I can fade too</div>

Simple jQuery approach, no setTimeout and no setInterval.
var loop = function(idx, totalLogos) {
var currentLogo = "#img" + idx;
$(currentLogo)
.delay(currentLogo)
.fadeIn(fadeDuration)
.delay(currentLogo)
.fadeOut(fadeDuration, function(){
loop( (idx + 1) % totalLogos, totalLogos);
});
}
loop(0, $('.logo').length);​
