A debug webpage made on vscode doesn't show the expected visualization - javascript

how are you?. I'm making several exercises from a book but because the code in the book appears to be run in pastebin or some related then I'm doing it with vscode and debbuging it on google chrome. The code of index.html is the following
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Today's Date</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<script src="variables-3.js"></script>
<link rel="stylesheet" href="style.css">
</body>
</html>
the code in style.css is the following
body {
background-color: #0080ff;
}
h1 {
color: #fff;
font-family: Arial, Helvetica, sans-serif;
}
body {
color: #f0f;
font-family: Arial, Helvetica, sans-serif;
}
and the javascript code in varable-3.js is the following
var div,
container = document.getElementById('container');
for(var i = 0; i<5;i++)
{
div = document.createElement('div');
div.onclick = function()
{
alert('This is box #'+i);
}
container.appendChild(div);
}
my launch.json is
{
"name": "Launch localhost",
"type": "chrome",
"request": "launch",
"url": "http://127.0.0.1:5500/",
"webRoot": "${workspaceFolder}/wwroot",
"runtimeExecutable":"C:/Program Files/Google/Chrome/Application/chrome.exe"
},
and my settings.json is
{
"liveServer.settings.port": 5500,
"liveServer.settings.CustomBrowser" : "chrome",
"liveServer.settings.AdvanceCustomBrowserCmdLine": "chrome --incognito --remote-debugging-
port=9222",
"liveServer.settings.NoBrowser" : false,
"liveServer.settings.ignoreFiles" : [
".vscode/**",
"**/*.scss",
"**/*.sass"
]
}
this suppose to show the background in some kind of sea blue and in the boddy around five squares in other color but only shows all the page in sea blue and I don't know why that is happening.
NOTE: here are code from several sources and including from other posts, I'm also using vscode-live-server.
How can I solve that problem?
Thanks in advance for the help.

First I wanna point that the following is only a modification of what the author did more a rearange than other thing, now the files:
index.html is
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Let</title>
<script src="https://unpkg.com/babel-standalone#6.15.0/babel.min.js"></script>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1>Click on a box</h1>
<div id="container"></div>
<h1>
<script src="variables-3.js"></script>
<link rel="stylesheet" href="style.css">
</h1>
</body>
</html>
variable-3.js is the same.
style.css is
#container {
display: flex;
justify-content: space-around;
}
#container>div {
height: 5em;
width: 5em;
background-color: purple;
}
And now it works.

Is there a way to use the html written by js in addEventListener?

I added 5 buttons in js to html and I want them to be defined with a one second delay, and because of this js, when it reaches the addEventListener line, those buttons are not defined and gives an error.
HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="./style.css">
<title>Document</title>
</head>
<body>
<div id="btn-adder"></div>
<script src="./script.js"></script>
</body>
</html>
CSS:
*{
padding: 0;
margin: 0;
box-sizing: border-box;
font-size: 20px;
}
body{
background: rgb(61, 61, 61);
}
#btn-adder{
margin-top: 40px;
text-align: center;
}
#btn-adder button{
padding: 5px;
margin: 5px;
}
JavaScript:
const btnAdder = document.getElementById("btn-adder");
for (let i = 0; i < 5; i++) {
setTimeout(function () {
btnAdder.innerHTML += `<button id="btn${i}">Button ${i}</button>`;
}, 1000);
}
for (let i = 0; i < 5; i++) {
document.getElementById(`btn${i}`).addEventListener("click", function () {
console.log(`Button ${i} clicked`);
});
}
Is there a way to make the addEventListener recognize the new variables?
Yes it's possible and you don't even need the second loop, which is slowing down your code. (even though you probably won't notice it)
Instead of adding the HTML directly to the btn-adder, you can create a new button and directly attach the eventlistener to it.
You can create a new HTML element with document.createElement() and then add all attributes, eventlisteners and everything else you need to the button.
Finally you'll add the newly created button with appendChild() as a new child element to your btn-adder element.
const btnAdder = document.getElementById("btn-adder");
for (let i = 0; i < 5; i++) {
setTimeout(function () {
// create button
const buttonElement = document.createElement('button');
buttonElement.id = `btn${i}`;
buttonElement.textContent = `Button ${i}`
// add eventlistener to the created button
buttonElement.addEventListener("click", function () {
console.log(`Button ${i} clicked`);
});
// add button to their parent
btnAdder.appendChild(buttonElement);
}, 1000);
}
*{
padding: 0;
margin: 0;

#btn-adder{
margin-top: 40px;
text-align: center;
}
#btn-adder button{
padding: 5px;
margin: 5px;

An approach close to what billyonecan mentioned but with use of appendChild instead of innerHTML which can lead to unwanted behaviour.

How to keep a random occurring botton inside the body(Or inside any div)

I Made a button using html, css and js which occurs randomly on the page.But i want the button inside the body tag and it keeps getting out.
HTML CODE:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script src="main.js" defer></script>
<link rel="stylesheet" href="style.css">
<title>SReflex</title>
</head>
<body>
<button class="random">1 </button>
</body>
</html>
CSS CODE:
*{
margin:0%;
padding:0%;
}
body{
height: 100vh;
width: 100vw;
position: fixed;
}
button.random {
/* looks of the button */
height: 3rem;
width: 3rem;
border: black;
border-style: solid;
border-radius: 50%;
display:block;
position:absolute;
}
JS CODE:
let temp= document.querySelector(".random");
temp.addEventListener("click",change);
function change(){
let posx = Math.floor(Math.random()*1000);
let posy = Math.floor(Math.random()*1000);
let posz = Math.floor(Math.random()*1000);
temp.style.left= posx + "vw";
temp.style.top= posy+ "vh";
temp.style.right= posz+ "vw";
}
How do i make the button to not go off screen, i want the page to not include the scroll bar.
Here is an easy way to do so, it works for the body or for a containing div because it's related to parent size.
check out the snippet.
let temp= document.querySelector(".random");
temp.addEventListener("click",change);
let maxw = temp.parentElement.clientWidth - 50;
let maxh = temp.parentElement.clientHeight - 50;
function change(){
let posx = Math.floor(Math.random() * (maxw));
let posy = Math.floor(Math.random() * (maxh))
temp.style.left= posx + "px";
temp.style.top= posy+ "px";
}
*{
margin:0%;
padding:0%;
}
body{
height: 100vh;
width: 100vw;
position: fixed;
}
button.random {
/* looks of the button */
height: 3rem;
width: 3rem;
border: black;
border-style: solid;
border-radius: 50%;
display:block;
position:absolute;
}

the -50 is to make sure it doesn't cross the edges, you can edit that to suit your needs.

progress bar for loading animation of webpage

I want to make a loading animation for my webpage which will take 8-10 sec to load using JavaScript or Ajax(Which I don't know)
The loading animation is a progress bar
Which I want to stop for every 1 sec for increment of 10% eg( https://codepen.io/gustitammam/pen/RRXGdj )

In the example you cited, you can just comment out the JS lines where the following fields are set:
.attr and .text
Regarding your desire to omit Bootstrap, however, you are not asking a simple technical question but proposing that somebody write a whole program fragment for you, which is generally not the intended purpose of Stack overflow.
Actually I didn't do it but I don't know his Stack ID so #0_0#1045(From Discord)

how to replace document.write with innerHTML

I want to replace the document.write with innerHTML. but it won’t create the links when I try it. I don’t know if there is an issue of how I am building the path variable so it won’t print out the links right. Right now it won’t print out any links.
<!DOCTYPE html>
<html lang="en">
<script>
var path = "";
var href = document.location.href;
var s = href.split("/");

}
i=s.length-1;
path+="<a class='crumb' href=\""+href.substring(0,href.indexOf(s[i])+s[i].length)+"\">"+s[i]+" </a>";
var url = path;
//document.getElementById(".breadcrumb").innerHTML = url;
document.write(url);

get element size during window resize fails

I have some code to get the size of the body on screen during a window resize event and use this elsewhere, however for some reason the size that is determined is always the size before the resizing:
$(document).on('ready', function () {
initResize();
});
function initResize() {
$(window).on('resize', doResize).trigger('resize');
};
function doResize() {
var wh = $('.game').height();
var ww = $('.game').width();
console.log("game " + ww +"x" +wh);
}
and the console output always returns the same data, yet if I change the selector to $(window) it changes as the window resizes. Can someone help please?
the html is very simple:
<!DOCTYPE HTML>

<script type="text/javascript" src="assets/js/init.js"></script>
</head>
<body>
<section class="game">
</section>

and the css:

margin: 0;
border: none;

}
html {

}
html, body {
