I'm trying to make a simple guessing game in JavaScript, but when I click submit button - nothing happens. This is a code from a book, so I think it should work. Do you have any idea what is wrong with it?
Below is the HTML and JS code. I have this two files in one folder.
I would be greatful for any ideas.
var randomNumber = Math.floor(Math.random() * 100) + 1;
const guesses = document.querySelector('.guesses');
const lastResult = document.querySelector('.lastResult');
const lowOrHi = document.querySelector('.lowOrHi');
const guessSubmit = document.querySelector('guessSubmit');
const guessField = document.querySelector('guessField');
let guessCount = 1;
let resetButton;
function checkGuess() {
var userGuess = Number(guessField.value);
if (guessCount === 1) {
guesses.textContent = 'Poprzednio wprowadzone liczby: ';
}
guesses.textContent += userGuess + ' ';
if (userGuess === randomNumber) {
lastResult.textContent = 'Gratulacje! Zgadłeś!';
lastResult.style.backgroundColor = 'green';
lowOrHi.textContent = '';
setGameOver();
} else if (guessCount === 10) {
lastResult.textContent = 'Koniec gry!';
setGameOver();
} else {
lastResult.textContent = 'Żle!';
lastResult.style.backgroundColor = 'red';
if (userGuess < randomNumber) {
lowOrHi.textContent = 'Zbyt mała liczba!';
} else if (userGuess > randomNumber) {
lowOrHi.textContent = 'Zbyt duża liczba!';
}
}
guessCount++;
guessField.value = '';
guessField.focus();
}
guessSubmit.addEventListener('click', checkGuess);
function setGameOver() {
guessField.disabled = true;
guessSubmit.disabled = true;
resetButton = document.createElement('button');
resetButton.textContent = 'Rozpocznij nową grę!';
document.body.appendChild(resetButton);
resetButton.addEventListener('click', resetGame);
}
function resetGame() {
guessCount = 1;
var resetParas = document.querySelectorAll('.resultParas p');
for (var i = 0; i < resetParas.length; i++) {
resetParas[i].textContent = '';
}
resetButton.parentNode.removeChild(resetButton);
guessField.disabled = false;
guessSubmit.disabled = false;
guessField.value = '';
guessField.focus();
lastResult.style.backgroundColor = 'white';
randomNumber = Math.floor(Math.random() * 100) + 1;

You are trying to get elements by type selector, but in HTML you haven't these types. Instead, try class selector.
const guessSubmit = document.querySelector('.guessSubmit');
const guessField = document.querySelector('.guessField');
I am making a dice game where you roll dice. When you roll a number that number adds to your total score. But when you roll a 1 you lose your total score and it switches to the other player. You can also hold to switch player.
As it is right now it become 0 after getting a 1 the first time. My problem is that when you switch back to the original starter player the score that was there before comes back. Like it does not stay the value of 0 but only looks like it.
var swithcing = false;
var current1 = 0;
var total1 = 0;
var current2 = 0;
var total2 = 0;
function roll() {
var randomnumber = Math.floor(Math.random() * 6) + 1;
var player1score = document.querySelector('.player1total');
var player1curent = document.querySelector('.player1');
var player2score = document.querySelector('.player2total')
var player2curent = document.querySelector('.player2')
if (randomnumber == 1) {
swithcing = !swithcing;
player1score.innerHTML = 0;
player1curent.innerHTML = 0;
player2curent.innerHTML = 0;
}
if (randomnumber == 1 && swithcing == false) {
player2score.innerHTML = 0;
}
if (swithcing == true) {
current2 += randomnumber;
player2score.innerHTML = current2;
player2curent.innerHTML = randomnumber;
}
if (swithcing == false) {
current1 += randomnumber;
player1score.innerHTML = current1;
player1curent.innerHTML = randomnumber;
}
}
function hold() {
swithcing = !swithcing;
}

I think your code should look something like this
let switching = false;
let current1 = 0;
let total1 = 0;
let current2 = 0;
let total2 = 0;
let randomnumber = 0
const player1score = document.querySelector('.player1total');
const player1current = document.querySelector('.player1');
const player2score = document.querySelector('.player2total');
const player2current = document.querySelector('.player2');
function roll() {
randomnumber = Math.floor(Math.random() * 6) + 1;
//console.log(randomnumber);
//logic for normal rolls
if(randomnumber > 1){
if(switching==true){
current2=randomnumber;//set to number rolled
total2+=randomnumber;//sum to total score
} else {
current1=randomnumber;//set to number rolled
total1+=randomnumber;//sum to total score
}
}
//logic if player loses
if (randomnumber == 1) {
//switch
switching = !switching;
//if switches to player 2
current1=0;//reset
current2=0;//reset
if(switching==true){
//console.log("Player 2 selected");
total2+=total1//total becomes player 1 previous total
total1=0;//player 1 total resets
} else {
//console.log("Player 1 selected");
total1+=total2//total becomes player 2 previous total
total2=0;//player 2 total resets
}
}
player1score.textContent = total1;
player1current.textContent = current1;
player2current.textContent = current2;
player2score.textContent = total2;
}
function hold() {
switching = !switching;
player1score.textContent = total1;
player1current.textContent = 0;
player2current.textContent = 0;
player2score.textContent = total2;
}

i am creating a tic tac toe game using javascript and i got it to work. However my only issue is that the reset button wont work. I have looked at other posts that involve a reset button but im not getting it to work. Also the function i tried using to for the reset button is document.getElementById("myForm").reset();
I'm a beginner doing this so im sorry if i made a mistake that seems apparent.

Mitchell,
The click event is not attached to the reset button and the 'drawboard' function isn't called on reset button click. you may have to make the below changes:
<input type='reset' style='width:100px;margin:0 50%;position:relative;left:-50px;' onclick="reset()">
function reset()
{
currentPlayer = 0;
player1pics = new Array();
player2pics = new Array();
drawBoard();
}
very new to Javascript here, and I think I'm having a logic issue. So basically for class I'm building a hangman game, and I am having trouble with double letters. for instance if the word is food, when I enter an "O" it will pass through the for loop, hit that first O, push it to the screen, and stop dead in its tracks. I can do whatever I want to that first "O" but a second one or any other repeated letter gets ignored. Now the alert I wrote directly under the start of the for() loop, will successfully print both "O's", as will logging it to the console, or even flat out writing document.write(splitWord[m]);
So to me, I think it has to be my if statement. I could be 100% wrong on this, but I assume that the if statement tells it to see the first "O", do what's in the bracket, and then move on to the next letter skipping any doubles. If I am right about this, what would be a better option to keep the loop going, so both "O's" would be filled. And if I am completely wrong, what would be a better course of action to accomplish this task. Any help would be very greatly appreciated.
Thanks

You can refer this below logic. In this example, I have given some inputs.

var displayString = [];
for(var i = 0; i < selectedWord.length; i++){
displayString[i] = "-"
}
var outputEle = document.getElementById("output");
var div = document.createElement('div');
div.innerText = displayString.join(" ");
outputEle.appendChild(div);
function checkPlayerChoiceNew(playerGuess){
var newWord = "";
var regExp = new RegExp(playerGuess,'ig')
selectedWord.replace(regExp, function(value, index){
displayString[index] = value;
return value;
});
var div = document.createElement('div');
div.innerText = displayString.join(" ");
outputEle.appendChild(div);
newWord = displayString.join("");
if(selectedWord == newWord){ alert("You Won the game"); }
//outputEle.innerText = displayString.join(" ");
}
checkPlayerChoiceNew('o');
checkPlayerChoiceNew('g');
checkPlayerChoiceNew('d');
checkPlayerChoiceNew('f');
<div id="output">

Basically, I'm making a simple javascript/html webpage game where you guess a number and you have three chances to guess correctly. I'm having a problem displaying the number of attempts a player has left (It gets stuck at three). The color change that is supposed to occur also doesn't happen.
It also doesn't reset the page's display after a refresh (it takes 5 playthroughs of the game to get it to reset).
Maybe my for loop/if statement is screwy?
Here's my code.
var guesses = 3;
var random = Math.floor((Math.random() * 10) + 1);
//start the guessing
handleGuess(prompt("Pick a number to win the game!"));
function handleGuess(choice) {
guesses--; //subtract one guess
if (guesses > 0) {
if (choice != random) {
document.body.style.backgroundColor = "#CC0000";
var x = "";
x = x + "You have " + guesses + " chances left" + "<br>";
document.getElementById("demo").innerHTML = x;
} else {
var x = "";
x = x + "You win!" + "<br>";
document.getElementById("demo").innerHTML = x;
document.body.style.backgroundColor = "#009000";
//return false;
}
} else {
//running out of turns
var x = "";
x = x + "Game Over!" + "<br>";
document.getElementById("demo").innerHTML = x;
document.body.style.backgroundColor = "#FF0000";
//return false;
}
}
The prompt is a blocking event, so you don't see the page update until after the prompts... try the example below, where setTimeout is used to allow a delay...
var guesses = 3;
var random = Math.floor((Math.random() * 10) + 1);
//start the guessing
handleGuess(prompt("Pick a number to win the game!"));
function handleGuess(choice) {
guesses--; //subtract one guess
if (guesses > 0) {
if (choice != random) {
document.body.style.backgroundColor = "#CC0000";
var x = "";
x = x + "You have " + guesses + " chances left" + "<br>";
document.getElementById("demo").innerHTML = x;
setTimeout(function() {
handleGuess(prompt("Try again!"));
},1000);//wait 1 second
} else {
var x = "";
x = x + "You win!" + "<br>";
document.getElementById("demo").innerHTML = x;
document.body.style.backgroundColor = "#009000";
//return false;
}
} else {
//running out of turns
var x = "";
x = x + "Game Over!" + "<br>";
document.getElementById("demo").innerHTML = x;
document.body.style.backgroundColor = "#FF0000";
//return false;
}
}
<h1 id="demo">You have 3 chances to guess the correct number.</h1>

Attention. This is a fully workable example, and definitely an "overkill demo" for your "blocking" request.
I've removed the prompt calls with new inputs, and created 2 buttons for the game. One that calls the Start Game, and a second for the "in game try attemps".
I'm assuming you are still learning so this example might be helpful for you,by showing the advantages of separating your code into different elements, based on what they are doing, and also making it easier for you to "upgrade" the features of your game.
I could replace a lot more repeated code to make it look better, but that would not make it so familiar anymore to you.

var i = ""

i = 3;
}
