I'm creating a simple card game that when a player wins the score should increase per win. But whenever I run this code it keeps resetting the score back to 0.
How can I make it so the scores keep increasing +1 if the corresponding player wins?
I've tried the below and it's unfortunately not working with what I have
$(document).ready(function(){
//storing our images, separating them out by suit. Orderimg from lowest to highest cards.
arrClubs=['2_of_clubs.png','3_of_clubs.png', '4_of_clubs.png', '5_of_clubs.png', '6_of_clubs.png', '7_of_clubs.png', '8_of_clubs.png', '9_of_clubs.png', '10_of_clubs.png', 'jack_of_clubs.png','queen_of_clubs.png', 'king_of_clubs.png', 'ace_of_clubs.png']
arrDiamonds=['2_of_diamonds.png','3_of_diamonds.png', '4_of_diamonds.png', '5_of_diamonds.png', '6_of_diamonds.png', '7_of_diamonds.png', '8_of_diamonds.png', '9_of_diamonds.png', '10_of_diamonds.png', 'jack_of_diamonds.png','queen_of_diamonds.png', 'king_of_diamonds.png', 'ace_of_diamonds.png']

//console.log(arrClubs);
var player1Score = 0;
var player2Score = 0;

Most likely you are setting player1Score and player2Score back to 0 each time you run it. Here's a working example:
const runGame = (() => {
var player1Score = 0;
var player2Score = 0;
return () => {
const card = Math.random();
const card2 = Math.random();
if (card < card2){
player2Score++;
console.log('Player 2 Wins! Score: ' + player2Score);
document.getElementById('p2').value = player2Score;
} else if (card > card2){
player1Score++;
console.log('Player 1 Wins! Score: ' + player1Score);
document.getElementById('p1').value = player1Score;
} else {
console.log('Tie!');
}
}
})();
document.getElementById('play').addEventListener('click', runGame);
<div id="player1Results"></div>
<div id="player2Results"></div>
<input type="text" readonly id="p1"/>
<input type="text" readonly id="p2"/>
<button id="play">Play</button>

Im trying shuffle the words on mouseover, but to shuffle a new word the previous word have be finished shuffling. This is because otherwise i will get an event.target.innerHTML of a word made up of random letters, if i mouseover the word while the alogorithm is shuffling.
How can i get over this problem, and shuffle any word on mouseover unless that specific word is allready shuffling?

I am new to JS, I want to the code to display number of attempts made, number of guesses remaining in this simple game. I have gotten lost in the code and I don't know what I am not doing right. The const remainingAttempts returns undefined yet I want to subtract number of attempts made from maxNumberOfAttempts.
const guessInput = document.getElementById("guess");
const submitButton = document.getElementById("submit");
const resetButton = document.getElementById("reset");
const messages = document.getElementsByClassName("message");
const tooHighMessage = document.getElementById("too-high");
const tooLowMessage = document.getElementById("too-low");

// Returns a random number from min (inclusive) to max (exclusive)
// Usage:
// > getRandomNumber(1, 50)
// <- 32
// > getRandomNumber(1, 50)
// <- 11
function getRandomNumber(min, max) {
return Math.floor(Math.random() * (max - min)) + min;
}
function checkGuess() {
// Get value from guess input element
const guess = parseInt(guessInput.value, 10);
attempts = attempts + 1;
hideAllMessages();
if (guess === targetNumber) {
numberOfGuessesMessage.style.display = "";
numberOfGuessesMessage.innerHTML = `You made ${attempts} guesses`;
correctMessage.style.display = "";
submitButton.disabled = true;
guessInput.disabled = true;
}
if (guess !== targetNumber) {
if (guess < targetNumber) {
tooLowMessage.style.display = "";
} else {
tooHighMessage.style.display = ""; //replaced else condition statement
}
const remainingAttempts = maxNumberOfAttempts - attempts;
numberOfGuessesMessage.style.display = "";
numberOfGuessesMessage.innerHTML = `You guessed ${guess}. <br> ${remainingAttempts} guesses remaining`;
}
if (attempts === maxNumberOfAttempts) {
maxGuessesMessage.style.display = "";
submitButton.disabled = true;
guessInput.disabled = true;
}
guessInput.value = "";
resetButton.style.display = "";
}

just increment attempts as attempts++; below const remainingAttempts = maxNumberOfAttempts - attempts;. this should solve the no. of attempts part.
In setup(), when you reset the number of attempts, you should be setting it to 5: maxNumberOfAttempts = 5;
Additionally, in checkGuess(), you should:
Make sure to decrease the number of attempts with each guess. Add maxNumberOfAttempts-- at the top of the function.
At the bottom of if (guess !== targetNumber), you can replace the variable in the message from ${remainingAttempts} to ${maxNumberOfAttempts}
, since maxNumberOfAttempts is now keeping track of the amount of attempts remaining.
Lastly, the next if statement can check if the user is out of attempts with if (maxNumberOfAttempts === 0) {...}
This eliminates the need to use 3 different 'attempt' variables since you're resetting back to '5' at each instance of setup() anyway.
I am trying to create the below game. The Javascript textcontent however is not displaying anything.
The Computer selects a random "secret" number between some min and max.
The Player is tasked with guessing the number. For each guess, the application informs the user whether their number is higher or lower than the "secret" number.
Extra challenges:
Limit the number of guesses the Player has.
Keep track/report which numbers have been guessed.
My code is as follows:
const submitguess = document.querySelector('.submitguess');
const inputno = document.querySelector('#secretno');
const resultmatch = document.querySelector('#resultmatch');
const highorlow = document.querySelector('#highorlow');
const guesslist = document.querySelector('#guesslist');
let randomNumber = Math.floor(Math.random() * 10) + 1;
let count = 1;
let resetButton;
function guessvalid() {
let input = Number(inputno.value);
//alert('I am at 0');
if (count === 1) {
guesslist.textContent = 'Last guesses:';
}
guesslist.textContent += input + ', ';
if (randomNumber === input) {
//alert('I am here 1');
resultmatch.textContent = 'Bazingaa!!! You got it absolutely right';
highorlow.textContent = '';
guesslist.textContent = '';
GameOver();
} else if (count === 5) {
resultmatch.textContent = 'Game Over !! Thanks for playing.';
//alert('I am here 2');
highorlow.textContent = '';
guesslist.textContent = '';
GameOver();
} else {
//alert('I am here 3');
resultmatch.textContent = 'Sorry the secret no and your guess do not match.Please try again !!';
if (randomNumber > input) {
//alert('I am here 4');
highorlow.textContent = 'Hint.The guess was lower than the secret no.';
} else if (randomNumber < input) {
//alert('I am here 5');
highorlow.textContent = 'Hint.The guess was higher than the secret no.';
}
}
count = count + 1;
input.value = '';
}
submitguess.addEventListener('click', guessvalid);
function GameOver() {
inputno.disabled = true;
submitguess.disabled = true;
resetButton = document.createElement('button');
resetButton.textContent = 'Lets play again';
document.body.appendChild(resetButton);
resetButton.addEventListener('click', reset);
}
function reset() {
count = 1;
const newDisplay = document.querySelectorAll('.display p');
for(let k = 0 ; k < newDisplay.length ; k++) {
newDisplay[k].textContent = '';
}
resetButton.parentNode.removeChild(resetButton);
inputno.disabled = false;
submitguess.disabled = false;
inputno.value = '';
randomNumber = Math.floor(Math.random() * 10) + 1;
}

Because I don't have enough contribution I have to write as an answer.
First is here
<input type='submit' class='submitguess'>
you should prevent the form to be executed and refresh so you have to add preventdefault. or simply change input submit to button type="button"
Second
const resetParas = document.querySelectorAll('.display p');
You should check this one. resetParas set but you check display length.
This is supposed to be a dice game where 2 people click to roll dice and they add what they get until they reach the goal. Their score resets if they roll over 9 though. Images of dice are supposed to pop up and show what they rolled. I know the images are not on here but it still shows that there should an image there with the error symbol. I am having trouble with the second image not showing up which should come from the SetPic2 function. Any help would be appreciated. Also, the PASS buttons are supposed the pass the person's turn to the other player but the main problem is the images.

Your selector will not finding your second image element.
var diceImage2 = document.querySelector("img2");
You could give your images IDs and reference them directly:
HTML
<img id="die1" src="" />
<img id="die2" src="" />
JS
var diceImage1 = document.getElementById('die1');
var diceImage2 = document.getElementById('die2');
I have worked for a while on this code for learning purposes. I finally got the program to work, however when you "roll the dice", it only allows the dice to be rolled 1 time; If you wish to roll the dice a second time you must refresh the screen.
I am trying to build a reset function for this program so that I can roll the dice as many times as I wish without a screen-refresh.
I have built the reset function, but It is not working... It clear's the DIV's, but doesn't allow the program to be executed again.
Can someone please help me out?
*I am a semi-noobie at Javascript, I am making programs like this to practice my skills.

Thank you!!

I rewrote and did what you were trying to do:
https://jsfiddle.net/n8oesvoo/
var log = logger('output'),
rollBtn = getById('roll'),
resetBtn = getById('reset'),
nDices = getById('numofdices'),
nSides = getById('numofsides'),
dices = null,
sides = null,
rolls = [],
doubles=0;
rollBtn.addEventListener('click',rollHandler);
resetBtn.addEventListener('click', resetHandler);
function rollHandler() {
resetView();
sides = nSides.value;
dices = nDices.value;
doubles=0;
rolls=[];
if(validateInput()) {
log('invalid input');
return;
}
//rolling simulation
var rolled;
while (dices--) {
rolled = Math.ceil(Math.random()*sides);
log('For Dice #'+(dices+1)+' Your Rolled: '+ rolled +'!');
rolls.push(rolled);
}
//finding doubles
//first sort: you can use any way to sort doesnt matter
rolls.sort(function(a,b){
return (a>b?1:(a<b)?0:-1);
});
for (var i =0; i < rolls.length; i++) {
if (rolls[i] == rolls[i+1]) {
doubles++;
i++;
}
}
if (doubles>0) log("You rolled " + doubles + " doubles");
}
function resetHandler(){
resetView();
nDices.value = nSides.value = '';
}
function resetView() {
getById('output').innerText = '';
}
function validateInput(){
return (isNaN(sides) || sides == '' || isNaN(dices) || dices == '');
}
function logger(x) { var output = getById(x);
return function(text){
output.innerText += text + '\n';
};}
function getById(x){ return document.getElementById(x); }
