I am trying to move my JQuery UIdraggable container into div(id="frame") but it is dragging everywhere in the webpage. So how can I move my draggable container into specific div(id="frame").So please give me a way to solve this problem. I am trying to make my own custom product designer plugin for which this my first feature.Here is my code :

Modify your #draggable object to this
$("#draggable").resizable().draggable({
revert: "invalid",
});
and add this to make you #frame droppable
$('#frame').droppable({
accept: '#draggable',
})
Read up the jqueryui docs on this, there is much more you can achieve with this. See here https://jqueryui.com/droppable/#photo-manager
You need to use accept of droppable. Like this
$('#frame').droppable({
accept: '#draggable',
})
It will solve you problem :)

I have made a game using JavaScript and I would like the background to change after the game is over or after isGamerOver = true to be more specific. Here is what I currently have. Right now when ever the game ends I get a Uncaught TypeError: Cannot read property 'style' of null.
function gameOver() {
console.log('game over')
isGamerOver = true
while (grid.firstChild) {
grid.removeChild(grid.firstChild)
}
grid.innerHTML = score
clearInterval(upTimerId)
clearInterval(downTimerId)
clearInterval(leftTimerId)
clearInterval(rightTimerId)
if(isGamerOver = true){
document.getElementById("grid").style.backgroundImage="url('backgrounds/background-up.png')";
}else{
document.getElementById("grid").style.backgroundImage="url('backgrounds/game-over.png')";
}
}
Here is the style sheet I am trying to change
.grid {
width: 400px;
height: 600px;
background-image: url(backgrounds/background-up.png);
position: relative;
font-size: 100px;
text-align: center;
color: #fff;
}
Here Is my HTML
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="UTF-8">
<title>100% Not Doodle Jump</title>
<link rel="stylesheet" href="style.css"></link>
<script src="app.js" charset="utf-8"></script>
</head>
<body>
<div class="grid"></div>
</body>
</html>
I also added a div in JavaScript
const grid = document.querySelector('.grid')
const doodler = document.createElement('div')
If you got your grid defined like that:
const grid = document.querySelector('.grid')
change this:
if(isGamerOver = true){
document.getElementById("grid").style.backgroundImage="url('backgrounds/background-up.png')";
}else{
document.getElementById("grid").style.backgroundImage="url('backgrounds/game-over.png')";
}
to this:
if(isGamerOver = true){
grid.style.backgroundImage="url('backgrounds/background-up.png')";
}else{
grid.style.backgroundImage="url('backgrounds/game-over.png')";
}
I have a few URLs that each show the status of some industrial equipment. I'm trying to create an HTML/Javascript solution that, on load, cycles through each of the websites at a set interval, with two buttons to stop the cycle (to take a closer look at something) and restart the cycle (either from the beginning or where it left off, I'm not picky). I'm REALLY rusty, but I got what I think is a good start. Unfortunately, it doesn't work. Here are the CSS and HTML:
html,
body {
height: 100vh;
width: 100vw;
}
#btStart {
position: absolute;
width: 50px;
height: 40px;
left: 20px;
top: 50px;
}
#btStop {
position: absolute;
width: 50px;
height: 40px;
left: 20px;
top: 120px;
}
#infoFrame {
width: 100%;
height: 100%;
}
.holder {
width: 100%;
height: 100%;
position: relative;
}
<!DOCTYPE HTML>
<html>
<head>
<title>Info Cycle</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link href="main.css" rel="stylesheet">
</head>
<body>
<div class="holder">
<iframe src="" id="infoFrame" frameborder="0" allowfullscreen>
<script type="text/javascript">
var urlArray = ['url1.com',
'url2.com',
'url3.com',
'url4.com',
'url5.com'];
var count = 0;
var i = document.getElementById('infoFrame');
var u = document.getElementById('url');
var timer = setInterval(cycleTimer, 5000);
function nextUrl() {
url = urlArray[++count];
count = (count >= urlArray.length - 1)? -1 : count;
return url;
}
function cycleTimer() {
u.innerHTML = '';
i.src = nextUrl();
i.onload = function(){
u.innerHTML = i.src;
}
}
</script>
</iframe>
<button type="button" id="btStart" onclick="var timer = setInterval(cycleTimer, 5000);">Start</button>
<button type="button" id="btStop" onclick="clearInterval(timer)";>Stop</button>
</div>
</body>
<footer>
</footer>
</html>
Before I added the buttons it would load, then 5 seconds later it would cycle correctly, and so on. Now it only shows the buttons. Looking at the requests, I believe what's happening in my CSS and structure is trash, and it's loading the appropriate URL, but not displaying. I should add, prior to the buttons I only had the iframe with the script in it as a proof of concept. I div'd it, added the stylesheet, and added the buttons, and now here we are.
This may be a rookie mistake, or something more complicated. I haven't done development in a long time, and I'm just trying to solve a little problem at work. If you could spare a minute, I'd be happy to know how to fix this, and also any feedback on what I could be doing better. I'd love to get back into doing more of this, so I'm interested to learn anything the community can share. I've searched the site and the internet, and I've found a couple of related solutions but nothing for this in particular.
Thanks!
EDIT:
In case it helps, below is the HTML before the buttons and stylesheet, which worked (it rotated between webpages every 7 seconds):

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

border: none;
margin: 0;
padding: 0;
overflow: hidden;
z-index: 999999;
height: 100%;
"></iframe>
<script type="text/javascript">
var urlArray = ['url1.com',
'url2.com',
'url3.com',
'url4.com',
'url5.com'];
var count = 0;
var i = document.getElementById('frame');
var u = document.getElementById('url');
var timer = setInterval(cycleTimer, 7000);
function nextUrl() {
url = urlArray[++count];
count = (count >= urlArray.length - 1)? -1 : count;
return url;
}
function cycleTimer() {
u.innerHTML = '';
i.src = nextUrl();
i.onload = function(){
u.innerHTML = i.src;
}
}
</script>
</body>
</html>
The iframe style was something I found in an old file I'd written (probably copied and pasted from Stack Overflow to just get a thing to work).
The problem here is having the script inside the iframe. If you move your script out of the iframe and put it under body or head then it will work.

function nextUrl() {
url = urlArray[++count];
count = (count >= urlArray.length - 1) ? -1 : count;
return url;
}
function cycleTimer() {
var i = document.getElementById('infoFrame');
var u = document.getElementById('url');
u.innerHTML = '';
i.src = nextUrl();
i.onload = function () {
u.innerHTML = i.src;

I tried searching for "file name changes to 0 in browser" both in Google and here, but got nowhere. This is a simple file which suddenly stopped opening. I can't even get at the inspector to troubleshoot it. Undo/redo history is lost, so that will not help. I'm guessing it's a simple mistake, but I have NEVER seen this before.

Thank you
You can't use the variable name location as it is a reserved word; what you're actually doing is setting the window.location variable to 0.
Rename it, or put it in a namespace or object.
Hey guys i was wondering if someone could help with some issues on my code.
Basically ive created 4 elements(divs) in an onclick event.From html i've also done so that same button dissapears
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<link rel="stylesheet" href="blackjack2.css">
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript" src="blackjack1.js"></script>
</head>
<body>
<button class= "boton" id="start">Play</button>
<button class= "boton" id="hit">Hit</button>
<button class= "boton" id= "stand">Stand</button>
<script type="text/javascript">
var jugar = document.getElementById('start')
var mas = document.getElementById('hit')
var mantener = document.getElementById('stand')
var cuerpo= document.getElementsByTagName('body')[0]
var crear_cartas= function() {
var card= document.createElement('div');
var texto =document.createTextNode("CASINO");
card.setAttribute("class","cartas");
card.appendChild(texto);
cuerpo.appendChild(card);
}
jugar.onclick= function(){
crear_cartas()
crear_cartas()
crear_cartas()
crear_cartas()
jugar.setAttribute('class','ocultar')
}
</script>
</body>
</html>
Up to there is ok , but im not sure if from jquery i can apply a filter that activates on the same onclick event that appears in javascript code (on those 4 created elements )to the even ones so that they make an animation lowering slightly the margin.
I've read about it but i am a bit at sea given that the filter would apply to created elements..
Thank you in advance guys
css class ".cartas" code included:
.cartas{
/*display: none;*/
margin: 260px 75px 0 75px;
display: inline-block;
border-radius: 10px;
border: 1px solid black;
padding-top: 50px;
height:100px;
width:100px;
color: #003366;
font-family: Muli,Helvetica Neue,Helvetica,sans-serif;
text-align: center;
background-color: #f0f8ff;
}
Add an onlcick event to all event divs. This event will add a class that will push the elements below those divs downward using a margin-bottom
Snippet below
var counter = 0;
var jugar = document.getElementById('start')
var mas = document.getElementById('hit')
var mantener = document.getElementById('stand')
var cuerpo = document.getElementsByTagName('body')[0]
var crear_cartas = function() {
card = document.createElement('div');
var texto = document.createTextNode("CASINO");
card.setAttribute("class", "cartas");
card.appendChild(texto);
cuerpo.appendChild(card);
}
jugar.onclick = function() {
for (var x = 0; x < 4; ++x) {
crear_cartas();
if ((x + 1) % 2 == 0) {
card.addEventListener('click', function() {
this.classList.add("move");
})
}
}
jugar.setAttribute('class', 'ocultar')
} //end func
div {
transition: margin-bottom 0.5s;
}
.move {
margin-bottom: 50px;
}

I have a div which can be dragged. If it's dragged, I would like to add its text to mouse and after leaving the mouse I want to show some menu like copy.
I have tried this:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<style>
#div1
{
width:350px;
height:70px;
padding:10px;
border:1px solid #aaaaaa;
}
</style>
<script>
function drag(ev)
{
ev.dataTransfer.setData("Text",ev.target.id);
}
function drop(ev)
{
ev.preventDefault();
//console.log(ev.dataTransfer);
//var data=ev.dataTransfer.getData("Text");
//ev.target.appendChild(document.getElementById(data));
alert(ev.target.id);
}
function allowDrop(ev){
ev.preventDefault();
}
</script>
</head>
<body>
<a draggable="true" ondragstart="drag(event)" id="drag-id" >dragme</a>
<div id="div1" style="border: solid 1px; width:40px; height:40px;" ondrop="return drop(event)" ondragover="allowDrop(event)"></div>
</body>
</html>
SOLUTION using fake drag 'n drop.
The problem here is that it only works inside the body element.
var fakeDrag = {
setup: function(){
fakeDrag.el = document.createElement('span');
fakeDrag.el.style['pointer-events'] = 'none';
fakeDrag.el.style['position'] = 'absolute';
fakeDrag.el.style['display'] = 'none';
fakeDrag.el.textContent = 'dragging';
document.body.appendChild(fakeDrag.el);
},
dragging: false,
drag: function(event){
if(event.target.classList.contains('drag')){
fakeDrag.dragging = true;
fakeDrag.source = event.target;
fakeDrag.el.style['display'] = 'inline';
}
},
dragmove: function(event){
fakeDrag.el.style['top'] = ++event.clientY+'px';
fakeDrag.el.style['left'] = ++event.clientX+'px';
},
drop: function(event){
if(event.target.classList.contains('drop') && fakeDrag.dragging){
event.target.textContent = fakeDrag.source.textContent;
}
fakeDrag.dragging = false;
fakeDrag.el.style['display'] = 'none';
}
};
fakeDrag.setup();
For menu you use it:
<div id="context_menu" style="width:150px;border:1px solid black;background-color:#EEEEEE;visibility:hidden;position:absolute;line-height:30px; padding-left: 10px">
<div id="copy" onclick="CopyFunction(this)" divIDMenu="">copy</div>
<div id="paste"onclick="PasteFunction(this)" divIDCopy="" divIDMenu="">paste</div>
<div id="cut" onclick="cutFunction(this)"divIDMenu="">cut</div>
<div id="delete" onclick="deleteFunction(this)" divIDMenu="">delete</div>
<div id="reload" onclick="reloadFunction(this)" divIDMenu="">reload</div>
</div>
