How do I get my etch-a-sketch program to "listen" to this dropdown menu instead of the buttons?

I'm new to Stack Overflow. I hope that I'm doing this correctly. ❤
I'm working on an old Etch-a-Sketch JavaScript project from months ago and decided to rework the 'mobile' form of the project because I hadn't bothered to do so at the time. At first, I tried just moving the buttons to the top horizontally, but I didn't like any of the variations I tried. So I decided I'd be better off with a dropdown menu instead that would appear when the screen is 500px or smaller, replacing the buttons.
The dropdown menu is supposed to do exactly what the buttons do - when a certain mode is selected, that's the mode that the program is supposed to switch to. For example, when the "Party mode" button is clicked, the program switches to "party mode". I want the dropdown menu to behave similarly - when the "party mode" option is selected, the program should switch to "party mode".
My logic was that I needed a function that grabbed the value of the dropdown menu, and then an "if" condition would run that pretty much says "If the value is x, x mode should run; else if the value is y, y mode should run", and so on. I added the function to the existing window.onload function so it would run upon the window loading. This didn't work.
Note that the dropdown menu will, in the future, only appear when the screen size is 500px or less. In addition, I still have the buttons on the screen for all sizes, just for testing/debugging purposes. When I'm done and have this figured out, the buttons will have "display = 'none'" and be hidden for the "mobile size".
Anyway, so yeah, the program is still just listening to the buttons, and not the dropdown menu. That leads me to believe that I need to somehow turn "off" the button mode? If that's the case, how do I do that? If that's not the case, what am I supposed to do here? Any help or insight would be greatly appreciated. Thanks!

Luckily, there's an easy way to do that. Add this piece of code into your javascript file and see the magic.
const dropdown = document.getElementById('dropdown-mode');
dropdown.addEventListener('change', (e) => {
setCurrentMode(e.target.value);
});

HTML, CSS and normal JS Code is not giving correct output

Making a sliding button to switch website theme using a CSS variable and javascript. It is working properly except there is a small bug that I am unable to fix. If I reload the page is light theme, the functionality of the button is being reversed. The "On" state of the button turns on light mode and off state toggles dark mode. However, the initial configuration is entirely opposite.
As you can see in the executable code snippet below, I tried solving this using click() function. This problem arises only when the value of num is 0 and page is reloaded. So, I thought if I store a variable in localStorage as false and check its value at the beginning of the function and if its false, then click the button and dont execute function, if its not false, then execute normally.
But it is not working for some reason. Please check this code:
if (!localStorage.getItem('thisvarisgud4me')) {
localStorage.setItem("thisvarisgud4me", "1")
}
document.getElementById("btn").addEventListener("click", change);
var c = "true";
if (!localStorage.getItem("clickc"))
{
localStorage.setItem("clickc", c);
}
function change() {
if (localStorage.getItem("clickc") == "false") {
localStorage.setItem("clickc","true");
document.getElementById("btn").click();
}
else if (localStorage.getItem("clickc") == "true") {
if (localStorage.getItem('thisvarisgud4me') == '1') {
localStorage.setItem("thisvarisgud4me", '0')
} else {
localStorage.setItem("thisvarisgud4me", '1')
}
var num = Number(localStorage.getItem('thisvarisgud4me'));
let root = document.documentElement;
root.style.setProperty("--numvar", num);
console.log(num);
if (num == 0) {
window.addEventListener("beforeunload", function (event) {
console.log("The page is redirecting")
alert("Reload");
localStorage.setItem("clickc", "false");
// document.getElementById("btn").click();
// debugger;
});
}

As you might have noticed, I also tried manipulating CSS pseudo class properties using JS. But that was a complete mess. Then, I thought of this approach and I was quite confident that it is correct but looks like I was wrong :(

Just adding a condition to setting "clickc" to "true" will probably do the trick. Here I've used a similar condition to that you've already used for the "thisvarisgud4me" key.
I took the opportunity to test out a utility I created that essentially implements the Storage API (that's what <script src="https://heretic-monkey.link/FauxStorage.js"></script> is in the HTML, and why all of your localStorage references now say localStore).
So if you decide to copy and paste this into your own code, just do a search and replace of localStore with localStorage.
if (!localStore.getItem('thisvarisgud4me')) {
localStore.setItem("thisvarisgud4me", "1")
}
document.getElementById("btn").addEventListener("click", change);
var c = "true";
if (!localStore.getItem("clickc")) {
localStore.setItem("clickc", c);
}
function change() {
if (localStore.getItem("clickc") == "false") {
document.getElementById("btn").click();
localStore.getItem("clickc") = "true";
} else if (localStore.getItem("clickc") == "true") {
if (localStore.getItem('thisvarisgud4me') == '1') {
localStore.setItem("thisvarisgud4me", '0')
} else {
localStore.setItem("thisvarisgud4me", '1')
}
var num = Number(localStore.getItem('thisvarisgud4me'));
let root = document.documentElement;
root.style.setProperty("--numvar", num);
console.log(num);
if (num == 0) {
window.addEventListener("beforeunload", function(event) {
console.log("The page is redirecting")
alert("Reload");
localStore.setItem("clickc", "false");
// document.getElementById("btn").click();
// debugger;
});
}
}
}

Here's how I would refactor it. This is more of an object-oriented way of doing things; it might not appeal to everyone and it certainly isn't meant to. It works for me and I'm the only one I need to make happy with it :).

}
this._darkMode = JSON.parse(localStore.getItem(this._darkModeKey));
}
return this._darkMode;
}
set darkMode(value) {
this._darkMode = value;
}
persist() {
localStore.setItem("thisvarisgud4me", JSON.stringify(this.darkMode));
}

Problem with adding two circular progressBar

I've created easy game. I added two circular progressBar in setTimeout, but still doesn't work as i expect. I wanna to these bars goes from 0 to 100% and finish. Unfortunately second of them is 2 times quicker than first. If I try add only one bar, there's not problem. I add my program on GH, there I selected the most important lines. I'm sorry for my english, I'm not native :/

Javascript Stop Propagation

I have been trying to figure out how to get an index of a dynamically created element so that I can write a function to delete it (splice).
I have figured out how to get the index really manually, but the problem is that I am getting Propagation from my event delegation and I am not sure how to stop it.
I have tried putting stopPropagation(), preventDefault(), stopImmediatePropagation() at various points within the function and have spent the last hour reading around online trying to figure out how to stop it. I even tried setting the e.bubble to false with no avail.
Could someone point me in the right direction here? Im sure its my inexperience but I am just out of ideas as of now.

I am wanting to figure out how to delete an item from the list
How about we change the last line of the function createDisplayItem to ..
function createDisplayItem(){
...
return newUl.appendChild(trashCan) // Added return
}
Now, you have an instance of the newly created trash can element being returned to the calling code, so now all we have to do is add a click event to this specific trash can element and let it delete its parent ul ..
submit.addEventListener("click", function() {
...
let trashCan = createDisplayItem();
trashCan.addEventListener('click', function(){
confirm('Are you sure you want to delete this?')
&& this.parentNode.remove()
})
...
});
So, since now in this code, each trash can takes care of its own parent element, you do not have to worry about finding the index from the parent display element anymore.

Restart Simon Game in javascript

How I can make the game restart from the beginning by clicking start button except reloading the whole page?
The problem occurs because when user clicks Start playGame function is called, but the a previous instance of playGame function is still running. I even thought about to kill a previous instance of function but in JS it can not be implemented except using webworker.terminate().
Here's the code:
document.addEventListener("DOMContentLoaded", function() {
'use strict';
var checkOn = document.querySelector("input[type=checkbox]");
var gameCount = document.getElementsByClassName("innerCount")[0];
var startButton = document.getElementById("innerStart");
var strictButton = document.getElementById("strictButton");
var strictInd = document.getElementById("strictIndicator");
var strictMode = false;
var soundArray = document.getElementsByTagName("audio");
var buttons = document.querySelectorAll(".bigButton");
var buttonArray = [].slice.call(buttons, 0);
checkOn.addEventListener("change", function() {
if (checkOn.checked) {
gameCount.innerHTML = "--";
} else {
gameCount.innerHTML = "";
}
});
strictButton.addEventListener("click", function() {
if (checkOn.checked) {
strictMode = !strictMode;
strictMode ? strictInd.style.backgroundColor = "#FF0000" :
strictInd.style.backgroundColor = "#850000";
}
});
function getRandArray() {
var array = [];
for (var i = 0; i < 22; i++) {
array[i] = Math.floor(Math.random() * 4);
}
return array;
}
startButton.addEventListener("click", function() {
if (checkOn.checked) {
var level = 0;
var randIndexArr = getRandArray();
sleep(700).then(function() {
playGame(randIndexArr, level);
});
}
});
function sleep(time) {
return new Promise(resolve => {
setTimeout(resolve, time)
})
}
function checkButton(randIndexArr, counter) {
var indexButton = 0;
var checker = function checker(e) {
var clickedButtonId = e.target.dataset.sound;
lightenButton(clickedButtonId);
if (+(clickedButtonId) === randIndexArr[indexButton]) {
if (indexButton === counter) {
counter++;
for (let i = 0; i < 4; i++) {
buttonArray[i].removeEventListener("click", checker, false)
}
sleep(2000).then(function() {
playGame(randIndexArr, counter);
});
}
indexButton++;
} else {
gameCount.innerHTML = "--";
if (strictMode) {
indexButton = 0;
counter = 0;
} else {
indexButton = 0;
}
for (let i = 0; i < 4; i++) {
buttonArray[i].removeEventListener("click", checker, false)
}
sleep(2000).then(function() {
playGame(randIndexArr, counter);
});
}
};
for (var i = 0; i < 4; i++) {
buttonArray[i].addEventListener("click", checker, false)
}
}
function playGame(randIndexArr, counter) {
if (counter === 22) {
return;
}
//Show the level of the Game
gameCount.innerHTML = counter + 1;
//Light and play user's input then check if input is correct
randIndexArr.slice(0, counter + 1).reduce(function(promise, div, index) {
return promise.then(function() {
lightenButton(div);
return new Promise(function(resolve, reject) {
setTimeout(function() {
resolve();
}, 1000);
})
})
}, Promise.resolve()).then(function() {
checkButton(randIndexArr, counter);
});
}
function lightenButton(id) {
var lightColorsArr = ["liteGreen", "liteRed", "liteYell", "liteBlue"];
soundArray[id].play();
buttonArray[id].classList.add(lightColorsArr[id]);
sleep(500).then(function() {
buttonArray[id].classList.remove(lightColorsArr[id])
});
}

I didn't dig super deep into your code, but it looks like the crux of it is you're using setTimeout(), and that timeout may still be running when you restart.
What you need to do is store the return value of setTimeout() which is actually an id you can then pass to clearTimeout(), which will stop that timeout.
So, on your sleep() function, store the id:
function sleep(time) {
return new Promise(resolve => {
this.timeoutId = setTimeout(resolve, time)
});
}
And when you go to restart your game:
// ...
if (this.timeoutId) {
clearTimeout(this.timeoutId);
this.timeoutId = null;
}
//...
And then also just make sure you don't have any other code that will get more than two timeouts running at the same time (or you'll lose one of the ids).
