I'm trying to make the standard number guessing game that MDN provides in their JS tutorial. I tried tweaking it a bit making different functions for the different scenarios.
It seems the global variable var userGuess = parseInt(guessField.value) is not working as your previous guess always comes up as NaN.
Also when the game resets the showWin() and showLoss() functions work but not the showError() function.
I am very new to JS and coding in general so there is most likely a silly mistake somewhere, if anyone could help me on this problem, that would be greatly appreciated!
var randNum = Math.floor(Math.random() * 100) + 1;
var guessField = document.querySelector('.guessField');
var guessSubmit = document.querySelector('.guessSubmit');
var guesses = document.querySelector('.guesses');
var lastResult = document.querySelector('.lastResult');
var lowOrHi = document.querySelector('.lowOrHi');
var guessCount = 1;
var resetButton;
var userGuess = parseInt(guessField.value);
function checkGuess() {
if(guessCount === 1) {
guesses.textContent = "Previous Guesses: ";
}
guesses.textContent += userGuess + ' ';
if(userGuess === randNum) {
showWin();
} else if(guessCount === 10) {
showLoss();
} else {
showError();
}
guessCount++;
guessField.value = '';
guessField.focus();
}
guessSubmit.addEventListener('click', checkGuess);
function showWin() {
lastResult.textContent = 'You won nice job schmuck';
lastResult.style.backgroundColor = 'green';
gameOver();
}
function showError() {
lastResult.textContent = 'Sorry, wrong guess';
if(userGuess > randNum) {
lowOrHi.textContent = 'Your guess was too high';
} else if(userGuess < randNum) {
lowOrHi.textContent = 'Your guess was too low';
}
}
function showLoss() {
lastResult.textContent = 'You lost, you schmuck';
lastResult.style.backgroundColor = 'red';
gameOver();
}
function gameOver() {
guessField.disabled = true;
guessSubmit.disabled = true;
resetButton = document.createElement('button');
resetButton.textContent = 'New Game';
document.body.appendChild(resetButton);
resetButton.addEventListener('click', resetGame);
}
function resetGame() {
guessCount = 1;
var resetParas = document.querySelectorAll('.resultParas');
for(i = 0; i < resetParas.length; i++) {
resetParas[i].textContent = '';
}
guessField.disabled = false;
guessSubmit.disabled = false;
resetButton.parentNode.removeChild(resetButton);
lastResult.style.backgroundColor = 'white';
randNum = Math.floor(Math.random() * 100) + 1;
}
<h1>Guessing Game</h1>
<p>Type in a number between 1 and 100 and I will tell you if it is too high or low.</p>

In your script, you call
parseInt(guessField.value) // effectively that is parseInt("") when it's empty
Calling parseInt() with an empty string returns NaN;
MDN in their example use:
var userGuess = Number(guessField.value);
Number("") returns a 0 number value.
You would also need to update the value of userGuess every time you call checkGuess(). So the alterations you need are:
// ... code
var userGuess = Number(guessField.value);
// ... the rest of code
function checkGuess() {
userGuess = Number(guessField.value)
// ... rest of code
}
// rest of code
You don't have to use Number() of course, you could also do some other condition checking, but Number() is an elegant way of accepting either numbers or an empty string.
UPDATE
New jsbin here.
For the resetGame() part: you were selecting the .resultParas like:
var resetParas = document.querySelectorAll('.resultParas');
Then you iterated over the results of that and replaced the .textContent of those elements. But those were not simple text nodes, they were parapgraph nodes with text nodes inside them. I changed it to:
var resetParas = document.querySelector('.resultParas').children;
It should be working! I've put some comments in the jsfiddle for more explanation.

So I'm following the modern JavaScript from the beginning by brad traversy, and in the guess number project the app ignores all the conditions in the first if statement and continue. I checked the code in the project file and it's the same, I tried switch statement, I put each condition in a separate if statement, and still doesn't work
let min = 1,
max = 10,
winningGuess = 2,
guessesNum = 3;
// Grab on UI Elements
const game = document.querySelector('#game'),
minNum = document.querySelector('.min-num'),
maxNum = document.querySelector('.max-num'),
guessInput = document.querySelector('#guess-input'),
guessBtn = document.querySelector('#guess-btn'),
message = document.querySelector('.message');
// Assign UI to min and Max
minNum.textContent = min;
maxNum.textContent = max;
// Add an EventListener
guessBtn.addEventListener('click', function() {
let guess = parseInt(guessInput.value);
if (isNaN(guess) || guess < min || guess > max) {
setMessage(`Please enter a Number between ${min} and ${max}`);
}
if (guess === winningGuess) {
gameOver(true, `Great Job ${winningGuess} is the Correct guess, You Won!`)
} else {
guessesNum -= 1;
if (guessesNum === 0) {
gameOver(false, `Sorry you lost, The correct guess was ${winningGuess}`)
} else {
guessInput.style.borderColor = 'red';
setMessage(`${guess} is not the correct number, You have ${guessesNum} guesses left. Please try again`, 'red');
guessInput = '';
}
}
});
function gameOver(won, msg) {
let color;
won === true ? color = 'green' : color = 'red';
guessInput.disabled = true;
guessInput.style.borderColor = color;
message.style.color = color;
setMessage(msg);
}
function setMessage(msg, color) {
message.textContent = msg;
message.style.color = color;
};
<div class="container">
<h1>The Number Guesser Game</h1>
<div id="game">

<input type="number" id="guess-input" placeholder="Enter Your Guess">
<input type="submit" value="Submit" id="guess-btn">
<p class="message"></p>
</div>
</div>
Your if statement is absolutely fine, the reason you never see the message "Please enter a Number between ${min} and ${max}" is because you let the code continue, and almost immediately that message is overwritten by a different one. Simply adding a return statement within your if block will solve this problem.
Note I also fixed this line guessInput = ''; which should be guessInput.value = '';
let min = 1,
max = 10,
winningGuess = 2,
guessesNum = 3;
// Grab on UI Elements
const game = document.querySelector('#game'),
minNum = document.querySelector('.min-num'),
maxNum = document.querySelector('.max-num'),
guessInput = document.querySelector('#guess-input'),
guessBtn = document.querySelector('#guess-btn'),
message = document.querySelector('.message');
// Assign UI to min and Max
minNum.textContent = min;
maxNum.textContent = max;
// Add an EventListener
guessBtn.addEventListener('click', function() {
let guess = parseInt(guessInput.value);
if (isNaN(guess) || guess < min || guess > max) {
setMessage(`Please enter a Number between ${min} and ${max}`);
return; // here
}
if (guess === winningGuess) {
gameOver(true, `Great Job ${winningGuess} is the Correct guess, You Won!`)
} else {
guessesNum -= 1;
if (guessesNum === 0) {
gameOver(false, `Sorry you lost, The correct guess was ${winningGuess}`)
} else {
guessInput.style.borderColor = 'red';
setMessage(`${guess} is not the correct number, You have ${guessesNum} guesses left. Please try again`, 'red');
guessInput.value = '';
}
}
});
function gameOver(won, msg) {
let color;
won === true ? color = 'green' : color = 'red';
guessInput.disabled = true;
guessInput.style.borderColor = color;
message.style.color = color;
setMessage(msg);
}
function setMessage(msg, color) {
message.textContent = msg;
message.style.color = color;
};

Try changing the const to let. You're editing all these later in your code:
let game = document.querySelector('#game'),
minNum = document.querySelector('.min-num'),
maxNum = document.querySelector('.max-num'),
guessInput = document.querySelector('#guess-input'),
guessBtn = document.querySelector('#guess-btn'),
message = document.querySelector('.message');
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');

What I'm trying to do is make a simple guessing game where the user can any the number without limit but will be graded at the end when the guessed the number correctly based on the number of their guesses. However, with my code when I enter a number and press the button to multiple times the hint changes from "Higher" to "Lower" even if the number is not changed also the message that should be displayed when the number is guessed correctly is not showing. Here's my code, I'm a beginner so there's bound to be errors in the code and any help is appreciated.
<fieldset>
<input type="number" id="guess" />
<button onClick="checknum();">Check Number</button>
</fieldset>
<fieldset>
<p>Your current status:</p>
<output id="status_output">You have yet to guess anything.</output>
</fieldset>
<script type="text/javascript">
function checknum(){
var randomNumber = Math.floor((Math.random() * 100) + 1);
var guessNumber = document.getElementById("guess").value;
//var guessNumber = parseInt(guess.value);
var statusOutput = document.getElementById('status_output');
var counter = 0;
var isguessed = false;
do {
counter = (counter + 1)
if (guessNumber < randomNumber) {
statusOutput.value = ("Higher");
}
else if (guessNumber > randomNumber) {
statusOutput.value = ("Lower");
}
else if (guessNumber = randomNumber) {
set (isguessed = true());
statusOutput.value = ("Correct" + mark());
}
}
while (isguessed = false);
}
function mark(){
if (counter < 10){
statusOutput.value("Excellent");
}
else if (counter > 10 && counter <20){
statusOutput.value("Okay");
}
else
statusOutput.value("Needs Practice");
}
</script>
In your while you are assigning false to the variable named isguessed.
You want to do while (isguessed === false) instead. This will check if isguessed is set to false
isguessed = false : assigns the varibles isguessed to false
isguessed === false : a boolean expression return true or false

But when i try to run the game and use the reset game button to restart the game then i am not able to manipulate guesses,lastResult and lowOrHi elements using textContent and backgroundColor properties.
Your blanking out everything inside .resultParas.. And this will include all you <p> tags. IOW: after doing that they have disappeared from the DOM, you can see this say in chrome inspector that .resultPara's after clicking reset game is now blank, and all your p tags have gone.
I think what you really want to do, is blank out the children (the p tags)..
You don't need querySelectorAll either, as in your case there is only the one.
var resetParas = document.querySelector('.resultParas');
for(var i = 0 ; i < resetParas.children.length ; i++) {
resetParas.children[i].textContent = '';
}
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.
/*function ChangeDif(Difficulty) {
var i = ""
if (Difficulty == 'easy'){
i = 10;
}
if (Difficulty == 'medium') {
i = 5;
}
if (Difficulty == 'hard') {
i = 3;
}
}
