This code from jsfiddle http://jsfiddle.net/Mp7R3/ is not working when I copy paste the code but it is working fine on jsfiddle .maybe I have some onLoad problem but I dont know how to solve it . I tried $(document).ready(function() but it didnt help .
Be sure you don't forget the script for calling jQuery in the <head> of your code:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
You can also try to place the code at the bottom of your code so it's can run only if the full page is loaded.
I also write below the simplest page to make this code work (normally you should separate HTML, CSS and JS), so you can compare it with your own:
<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

So I'm trying to make a prototype for a little project I'm trying to work on, were a div moves 10 pixels to right every second. I've tried to look up how to do similar things like I want to do, but I can't make it work.
I want to make it with JavaScript, but when JavaScript is executed, the squareStyleTop value just add "100px", so it just increases and after a few seconds the value looks like this:
This is what I've been able to do so far:
//setTimeout(function(){ alert("Hello"); }, 3000);
var squareStyle = document.getElementById("sjuku").style;
var squareStyleTop = squareStyle.top
function TingLing() {
squareStyleTop += "10px";
console.log("squareStylTop is ", squareStyleTop)
}
setInterval(TingLing, 1000);
#denneYes {
position: absolute;
left: 1300px;
}
#sjuku {
height: 2em;
width: 2em;
background-color: #00ffff;
position: absolute;
}
Go bak
<div id="sjuku"></div>
let squareStyleTop = 10;
function TingLing (){
squareStyleTop += 10;
document.getElementById("sjuku").style.top = squareStyleTop + "px";
console.log("squareStylTop is ", squareStyleTop)
}
setInterval(TingLing, 1000);
#denneYes { position: absolute;
left: 1300px;
}
#sjuku {
height: 2em;
width: 2em;
background-color: #00ffff;
position: absolute;
}
<html>
<head>
<title>Indax</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
Go bak
<div id="sjuku"></div>
<script src="main.js"></script>
</body>
</html>
Try changing following:
function TingLing (){
squareStyleTop += "10px";
console.log("squareStylTop is ", squareStyleTop)
}
to
function TingLing (){
squareStyleTop = ( parseInt( squareStyleTop == null ? 0 : squareStyleTop ) + 10 ) + 'px';
console.log("squareStylTop is ", squareStyleTop)
}
Essentially I am converting '10px' to 10 so I can add 10 to it and afterwards I am concatenating it 'px'
Make sure to set an initial top value in your html file. This would be my approach of doing it.
const square = document.getElementById("sjuku");
const increment = 10;
setInterval(() => {
square.style.top = parseInt(square.style.top, 10) + increment + "px";
console.log("squareStylTop is", square.style.top);
}, 1000);
#denneYes {
position: absolute;
left: 1300px;
}
#sjuku {
height: 2em;
width: 2em;
background-color: #00ffff;
position: absolute;
}

I've been playing around with the code below and using it to create a progress bar that responds to a certain type of data input. The data I'm using comes in the form of an array but I've noticed that the code only creates one progress bar.
How could I embed this within my for loop so that it creates a separate progress bar for each item in the array?
function move() {
var elem = document.getElementById("myBar");
var width = 0;
var id = setInterval(frame, 2000);
function frame() {
if (width >= 100) {
clearInterval(id);
} else {
width=width + 10;
elem.style.width = width + '%';
elem.innerHTML = ((100 - width)/10) + ' mins';
}
}
}
move();
#myProgress {
width: 80%;
background-color: #ddd;
horizontal-align: center;
}
#myBar {
width: 0%;
height: 30px;
background-color: #4CAF50;
text-align: center;
line-height: 30px;
color: white;
}

Here is the link to what I'm working on: My Workspace
Side Note: I've been trying to get the progress bar to be centered on the page with a margin: 200px on either side. The margin attribute in my CSS doesn't seem to be doing this and only applying the margin to the left but not to the right - where am I going wrong with this?
Try this
<html>
<style>
#myProgress {
width: 100%;
background-color: #ddd;
}
.myBar {
width: 10%;
height: 30px;
background-color: #4CAF50;
text-align: center;
line-height: 30px;
color: white;
}
</style>
<body>
<div id="myProgress">
</div>
</body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js">
</script>
<script>
$(document).ready(function(){
var progressbars="";
var i;
for (i = 1; i <=10; i++) {
progressbars+="<div class='myBar' style='width:"+i+"%'"
+ " id='myBar"+i+"px'"
+">"+i+"%"+"</div><br/>";
}
$("#myProgress").html(progressbars);
});
</script>
</html>
Using Javascript Only
Just replace previous script with this
<script>
window.onload=function(){
var progressbars="";
var i;
for (i = 1; i <=10; i++) {
progressbars+="<div class='myBar' style='width:"+i+"%'"
+ " id='myBar"+i+"px'"
+">"+i+"%"+"</div><br/>";
}
document.getElementById("myProgress").innerHTML=progressbars;
}
This will generate
I see that you have included bootstrap 4
In that case you can create progress bars with Bootstrap
var progressbars="";
for (var i = 1; i <=10; i++) {
progressbars+='<div class="progress">'
+'<div class="progress-bar" role="progressbar" style="width: '+i+'%" aria-valuenow="'+i+'" aria-valuemin="0" aria-valuemax="100">'+i+'%</div>'
+'</div>';
}
document.querySelector(".feefo").innerHTML=progressbars;
And it looks a lot nicer :)

The script is successfully work with 1 line.
Output :

Question is :
Is there another way to print 1 line without #def { width:400px; }?
(When I try #def { display:inline; }
Output :
Cihampelas
Demin Center
)
When object's left = -200px, I want to reserve in same way, but I have no idea.
I am trying to achive a fixed position after a certain point of the page is passed using CSS JS and HTML.
Also I don't know the bet aproach in loading the function into the html doc, I was thinking on using the onload...
Here is what I have done until now:
<!DOCTYPE html>
<html>
<head>
<script>
var left1 = document.getElementById("left1");
var origOffsetY = left1.offsetTop;
function onScroll(e) {
window.scrollY >= origOffsetY ? left1.style.position = "fixed":
left1.style.position="absolute";
}
document.addEventListener('scroll', onScroll);
</script language="JavaScript">
<style>
#main {
position: relative;
width: 620px;
margin: 0 auto;
height: 1800px;
}
#left1{
position: absolute;
font-family: sans-serif;
left: 0px;
top: 10px;
height: 200px;
width: 300px;
background-color: #F6D565;
}
#right1{
position:absolute;
font-family: sans-serif;
top: 10px;
right: 0px;
height: 300px;
width: 300px;
background-color: #DFFCC2;
}
#right2{
position:absolute;
top: 320px;
right: 0px;
font-family: sans-serif;
height:300px;
width: 300px;
background-color: #DFFCC2;
}
#right3{
position:absolute;
top: 630px;
right: 0px;
font-family: sans-serif;

}
</style>
</head>
<body >
<div id="main">
<div id="left1">aaaaaaaaaaaaaaaaaaaa</div>
<div id="right1">bbb</div>
<div id="right2">cccccccccccccccccccccc</div>
<div id="right3">ddd</div>
</div>
</body>
</html>
DEMO
The DOM is not available when you are trying to access div with id left1.
So your first line var left1 = document.getElementById("left1"); will give error.
Instead Wrap your current code within window.onload
<script>
window.onload = function() {
var left1 = document.getElementById("left1");
var origOffsetY = left1.offsetTop;
function onScroll(e) {
console.log("calling scroll")
window.scrollY >= origOffsetY ? left1.style.position = "fixed":
left1.style.position="absolute";
}
document.addEventListener('scroll', onScroll);
}
</script>
Else place your javascript just above the </body> tag
Yes, you can use onload to call a function after the page is loaded like so:
<script type="text/javascript">
function onLoad(){
var left1 = document.getElementById("left1");
var origOffsetY = left1.offsetTop;
}
function onScroll(e) {
window.scrollY >= origOffsetY ? left1.style.position = "fixed":
left1.style.position="absolute";
}
document.addEventListener('scroll', onScroll);
</script>
and replace
<body>
with:
<body onload="onload()">
Note that you can still leave the script in the header of your page (between <head> and </head>).
You can use window.addEventListener() if you don't like <body onload="onload">, but IE won't support this. See "Hook a javascript event to page load" for details.
You have to load your script after the DOM is created. The time you are trying to parse var left1 =document.getElementById("left1"); DOM hasn't created yet so var left1 is null
TRY:
<!DOCTYPE html>
<html>
<head>
<style>
//YOUR CSS
</style>
</head>
<body >
<div id="main">
<div id="left1">aaaaaaaaaaaaaaaaaaaa</div>
<div id="right1">bbb</div>
<div id="right2">cccccccccccccccccccccc</div>
<div id="right3">ddd</div>
</div>
<script>
var left1 = document.getElementById("left1");
var origOffsetY = left1.offsetTop;
function onScroll(e) {
window.scrollY >= origOffsetY ? left1.style.position = "fixed":
left1.style.position="absolute";
}
document.addEventListener('scroll', onScroll);
</script language="JavaScript">
</body>
</html>
EDIT:
By changing position you have to rearrange your item.
Try:
function onScroll(e) {
if (window.scrollY >= origOffsetY) {
left1.style.position = "fixed";
left1.style.left = "66px"
} else {
left1.style.position = "absolute";
left1.style.left = "0px";
}
}
