using JS to make tic tac toe

I have made a tic tac toe using JS however it has some problems My code is:
let x = [];
let o = [];
let xTurn = false;
let winPat = [
['00', '10', '20'],
['01', '11', '21'],
['02', '12', '22'],

my problem is that when the game ends, say X wins, the image is not rendered on the screen, and alert() is called. I googled a lot and found no solutions.
details and clarity:
the image is not rendered on screen at the end of the game. try on your computer and see. alert() is called before the image is present in-game which results in a bad user experience. hence I need a solution.

Here your append() function is not able to complete image load & your checkWinOrDraw() function got called that's why this is happening.
Please try with the below code i am calling the checkWinOrDraw() once image gets loaded or failed.
for (let i = 0; i <= 2; i++) {
for (let j = 0; j <= 2; j++) {
let newElement = document.createElement('td');
tableR.item(i).appendChild(newElement);
newElement.addEventListener('click', () => {
if (elementIsEmpty(newElement)) {
const img = document.createElement('img');
if (xTurn) {
img.src = 'https://dummyimage.com/20x20/3a4ca6/fff';
x.push(String(i) + String(j))
} else {
img.src = 'https://dummyimage.com/30x30/fff/fff';
o.push(String(i) + String(j))
}
console.log(xTurn)
xTurn = !xTurn
img.addEventListener('load', checkWinOrDraw)
img.addEventListener('error', checkWinOrDraw)
newElement.appendChild(img)
}
})
}
}
function checkWinOrDraw(e,xTurn) {
//console.log('checking',xTurn)
for (let i = 0; i < winPat.length; i++) {
if (xTurn) {
if (winPat[i].every(element => x.includes(element))) {
alert('X wins')
reset()
return
}
} else {
if (winPat[i].every(element => o.includes(element))) {
alert('O wins')
reset()
return

How to add a button that becomes active after conditions are met js

I continue to make a game on js game "Believe / Don't Believe". Assertion titles appear on the screen one by one. The user responds to each statement in turn. There are 5 statements in total. If the user clicked on the False button then the following statement appears. And if it's true then a description appears. You can go to the next question by clicking on the white circle under the headings, which turns into red if an answer has already been given to it (any), or by clicking on the Next button.
Question:
How do I add a Next button to go to the next question? Until the user has answered the question, it is not active until he gives an answer.

Please check the snippet

You can do it either by modifying the disabled attribute or by adding/removing a class.I recommend using the disabled attribute.
Modifying attribute
You will want to switch between <button disabled="true"> and <button disabled="false">
With javascript, it could look like this:
if flag=1:
document.getElementById("your-btn").disabled = true;
else:
document.getElementById("your-btn").disabled = false;
Example for the same
const myFunction=()=>{
document.getElementById("your-btn").disabled = false;
}
<h1>Activate the disabled button conditionally</h1>
<button type="button" id="your-btn" disabled="false">Click Me!</button>
<button type="button" onclick="myFunction()">Click me to Activate the previous button</button>
Do tell me wether I was of any help :)

How to make a reset button appear after certain requirements?

So, i want a reset button to appear on my page when the score of the player reaches 5. But i can't seem to make it appear.
if (Score == 5) {
btnQuestion.disabled = true;
txtQuestionFeedback.innerText = "Correct! \n Congratulations, you've got 5 stars!";
imgScore5.src = "Images/StarOn.gif";
document.getElementById(btnReset).innerHTML = btnReset;
}

Try the following:
1) Insert your button element inside a DIV like this for easier reading
<div id="resetButtonDiv">
<button id="resetButton"></button> <!-- here goes your button config -->
</div>
2) Change the style like this using JS
<script>
function showResetButton() {
document.getElementById("resetButton").style.display = "none";
if (Score == 5) {
// Replace "Score" with your variable or element
document.getElementById("resetButton").style.display = "show";
}
}
showResetButton()
</script>

This was my way to do it:
ScoreBoard = function(sId, sIntoNode = '', fnOnChange = null) {
this.m_sId = sId != '' ? sId : 'scoreboard';
this.m_iScore = 0;
this.m_fnOnChange = fnOnChange;
if(sIntoNode != '') {
let TargetNode = document.getElementById(sIntoNode);
if(TargetNode) {
TargetNode.innerHTML = TargetNode.innerHTML + '<div class="scoreboard-score" id="' + this.m_sId + '">0</div>';
}
}
}
ScoreBoard.prototype.SetScore = function(iNewScore) {
this.m_iScore = iNewScore;
let scoreBoard = document.getElementById(this.m_sId);
if(scoreBoard) {
scoreBoard.innerHTML = this.m_iScore;
}
if(this.m_fnOnChange && typeof this.m_fnOnChange == 'function') {
this.m_fnOnChange(this);
}
}
ScoreBoard.prototype.AddScore = function(iAmount) {
this.SetScore(this.m_iScore + iAmount);
}
ScoreBoard.prototype.Reset = function() {
this.SetScore(0);
}
ScoreBoard.prototype.GetScore = function() {
return this.m_iScore;
}
function OnScoreChange(target) {
let resetBtn = document.getElementById('myScore-reset');
if(resetBtn) {
if(target.GetScore() >= 5) {
resetBtn.style.display = "block";
} else {
resetBtn.style.display = "none";
}
}
}
var myScore = new ScoreBoard('myScore', 'score', OnScoreChange);
var i = 0;
function test() {
myScore.AddScore(1);
i++;
if(i < 20) setTimeout(test, 1000);
}
test();
div#score {
padding: 12px;
background-color: darkgrey;
font-family: Arial;
border-radius: 12px;
box-shadow: 0 0 12px 3px black;
}
div.score-head {
background-color: black;
color: white;
padding: 6px;
border-top-left-radius: 6px;
border-top-right-radius: 6px;
}
div.scoreboard-score {
background-color: #EAEAEA;
padding: 6px;
border-bottom-left-radius: 6px;
border-bottom-right-radius: 6px;
}
div#score button {
display: none;
}
<div id="score">
<button onClick="myScore.Reset();" id="myScore-reset">Reset Score</button>
<div class="score-head">Score:</div>
</div>

I've sorted it guys!
Instead, i just used a visibility attribute on the button to hide it on page startup. And then called on that attribute in a Function for HideButton().
```
function ShowResetButton() {
document.getElementById("btnReset").style.visibility = "visible";
}
```
But thank you all for your input! i really appreciate it!
Take it easy,
Happy coding!

So my question is, How can I keep the value inserted in the text area even after I reload the page (from the "Threshold1()" function)? I found a few examples with "localStorage" and JQuery, but I have no idea how to call the saved value when I reload the page.
Any help would be appreciated.
Thanks in advance,
Stefan.

Local Storage Explained
The localStorage object likes to store strings, so how would one store large objects, let's say some complex data structure? - Simple, JavaScript has a neat function built in, look up JSON.stringify(object). So all you would need to do is something like below to store some complex object is something like the code I've provided below. Then to retrieve an object from the localStorage you'll want to use JSON.parse(object);.
To look into localStorage, I strongly suggest you take a look at the likes of MDN and if you want to look into the JSON.parse and JSON.stringify functions, you can also find them both here:
JSON.parse() link
JSON.stringify() link
// vanilla js version of $(document).ready(function(){/*code here*/});
window.ready = function(fnc) {
if (typeof fnc != "function") {
return console.error("You need to pass a function as a param.");
}
try { // try time out for some old IE bugs
setTimeout(function () {
document.addEventListener("DOMContentLoaded", fnc());
}, 10)
} catch (e) {
try { // sometimes timeout won't work
document.addEventListener("DOMContentLoaded", fnc());
} catch (ex) {
console.log(ex);
}
}
};
// shorter than $(document).ready();
ready(function() {
var object = {
name: "Jack",
age: 30,
location: "U.S.A.",
get_pay: function() {
console.log("test");
}
},
test;
console.log(object);
var obj_string = JSON.stringify(object);
// run a test
var run_test = function() {
// output the stored object
test = localStorage.getItem("test");
console.log(test);
// to make js turn it into an object again

You can use this JSFiddle : http://jsfiddle.net/xpvt214o/45115/
here we are using Cookie concept and jquery.cookie.js to accomplish what you are trying to do.
to properly check the fiddle you need to press "Run" every time, you can open the same fiddle in 2 tabs write something in the first fiddle then just press run in the 2nd fiddle tab the value should automatically update, here the
$(function(){}); replicates your pageload

My question isn't exactly answered, but I completely avoided storing info on a device. Now I'm just reading the value straight from the arduino and it works. But thanks to everyone that provided some help.

Calculate the word amount from an <input>?

The following code converts text into equal paragraphs, based on the users input character amount.
Is it possible for the input box to calculate the amount of words for each paragraph instead of being based on the character amount?
JSFiddle
If an updated fiddle could please be provided, would be much appreciated, as I am still new to coding.
Thank You!

How about this? It uses jQuery, but as you used the library in your original submission, I hope that won't be an issue:
HTML
<textarea id="input"></textarea>
<br/>
<button id='divide'>Divide</button>
<div id="paras"></div>
CSS
#input {
resize: none;
height: 200px;
width: 100%;
}
JS
$(function() {
$("#divide").click(function() {
var text = $("#input").val();
var wpp = 10 // words per paragraph
var words = text.split(" ");
var paras = [];
for (i = 0; i < words.length; i += wpp) {
paras.push(words.slice(i, i + wpp).join(" "));
}
$.each(paras, function(i, para) {
$("#paras").append("<p>" + para + "</p>");
});
});
})
