I'm trying to simulate an animate effect via jQuery that consists drag and drop as events to be fired. The code I use seems to be fine until the point when I have to swap divs by setting their display to none/block. Whenever I swap to the first div it perfectly executes the animation but when it gets on the 2nd div (after swapped) it doesn't fire the droppable event. I chose to have id selectors for the respective divs to instance the container of the droppable event hence to animate. I'm stuck and are out of any solution after searching numerous results so far. Thank you in advance. Here is my JS fiddle I prepared to easily understand my problem.

Your problem is you were only calling droppable once, on only one of the items. Once the .droppable() function is also put inside the change button click, it should work.
put this inside change function:
$("#" + makina).droppable({
drop: function () {
doAnimate(makina);
}
});
example:
http://jsfiddle.net/xoxxbr4t/7/
You aren't binding droppable to your second element. You call this function once:
$("#" + makina).droppable({
drop: function () {
doAnimate(makina);
}
});
Since your "makina" at this point is div1, that's the only thing that gets bound. I made that it's own function:
function setDroppable(makina) {
$("#" + makina).droppable({
drop: function () {
doAnimate(makina);
}
});
}
And then called it for both divs in your setup:
setDroppable('div1');
setDroppable('div2');
And now it works fine. Here's the updated fiddle
Thanks Michal indeed that was the answer but I think a good programmer would reduce the redundant snippet of code as far as I can tell those are duplicate lines from the $(document).ready() function. However it's a solution. And right after I read your post I decided to post the answer myself as it follows:
//Previous
$("#" + makina).droppable({
drop: function () {
doAnimate(makina);
}
});
//Current
$("#wrapper").droppable({
drop: function () {
doAnimate(makina);
}
});
Since I'm using nested divs I then realised that I could make the parent div droppable and just animate the child which is active(shown).

All I'm trying to do is something like this mechanism:
Here is what I've tried so far:
$(document).ready(function(){
$('a').bind('mouseenter', function() {
var self = $(this);
this.iid = setInterval(function() {
var tag_name = self.text(),
top = self.position().top + self.outerHeight(true),
left = self.position().left;
self.append("<div class='tag_info'>Some explanations about"+tag_name+"</div>")
$(".tag_info").css({top: top + "px", left: left + "px"}).fadeIn(200);
}, 525);
}).bind('mouseleave', function(){
this.iid && clearInterval(this.iid);
});
});
body{
padding: 20px;
}
a {
color: #3e6d8e !important;
background-color: #E1ECF4;
padding: 2px 5px;
}
.tag_info{
position: reletive;
width: 130px;
height: 30px;
display:none;
background-color: black;
color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a>tag1</a>
<a>tag2</a>
As you see, it will be repeated every time. How can I execute it once per hover? And why the position doesn't apply?
Also is what I'm doing a right algorithm for such thing?
Thank you.
I am not sure why you are using setInterval but I think this should work. I removed setInterval and everytime the mouseenter event occurs we can append <div class='tag_info'> and every time mouseleave event occurs we can remove the the appended div.
$(document).ready(function(){
$('#test').bind('mouseenter', function() {
var self = $(this);
var tag_name = self.text(),
top = self.position().top + self.outerHeight(true),
left = self.position().left;
self.append("<div class='tag_info'>Some explanations about"+tag_name+"</div>")
$(".tag_info").css({top: top + "px", left: left + "px"}).fadeIn(200);
}).bind('mouseleave', function(){
$(this).children('.tag_info').remove();
});
});
body{
padding: 20px;
}
a {
color: #3e6d8e !important;
background-color: #E1ECF4;
padding: 2px 5px;
}
.tag_info{
position: reletive;
width: 130px;
height: 30px;
display:none;
background-color: black;
color: white;
}

<a id="test">tag1</a>
Like Dij said:
What you're doing:
setInterval - (repeats your function every 525ms)
What you want:
setTimeout - (executes your function once after 525ms delay)

I want to remove a dragged element, but it should only be removed when it doesn't have the class "nodrop".
here's my current code it removes all elements wheter i included an if function:
$(".löschen").droppable({
drop: function(event, ui) {
if (!$(this).hasClass("nodrop")){
ui.draggable.remove();
findTotal();
}
}});
I don't have any plan what I've done wrong...
You get the current drop container (.löschen) with $(this). With $(ui.draggable) you get the dropped element with class nodrop.
$(".draggable").draggable();
$(".löschen").droppable({
drop: function(event, ui) {
var $dropContainer = $(this);
var $dragContainer = $(ui.draggable)
console.log($dropContainer, $dragContainer);
if (!$dragContainer.hasClass("nodrop")){
$dragContainer.remove();
}
}});
.draggable {
width: 100px;
height: 100px;
}
.drop {
background-color: green;
}
.nodrop {
background-color: red;
}
.löschen {
width: 200px;
height: 200px;
background-color: #ccc;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<div class="draggable nodrop">NO DROP</div>
<div class="draggable drop">DROP</div>
<div class="löschen">TRASH</div>
The goal of the script is drag element but leave copy of the element.
function makeDraggable() {
$('.col-md-4').addClass('is-draggable');
$('.is-draggable').draggable({
start: function(event, ui){
if($(this).hasClass('not-draggable'))
return;
var cl = $(this).clone();
$(this).after(cl);
var of = cl.offset();
$(this).addClass('rect').offset({top:of.top,left:of.left}).css({width:cl.css('width'), height:cl.css('height')});
makeDraggable();
$(this).addClass('not-draggable');
}
});
}
makeDraggable();
When you mousedown on some boxes it clones box and then draggable placing this element to the left top corner and don't allow to set my own offset. I want the dragable element left on the same place and don't jump. Demo jsfidle
You can't use offset because it's already used by the drag event. You can use margins to offset your draggable.
Also, use ui.helper to get the offset
var of = $(ui.helper).offset();
$(this).addClass('rect').css({'margin-top':of.top,'margin-left':of.left}).css({width:cl.css('width'), height:cl.css('height')});

I have a situation like this set up:
http://jsfiddle.net/gz4Z7/2/
The difference in my situation is that all of the elements are created in javascript with document.createElement, and they are appended to the DOM of various webpages on the internet.
Everything works great except one thing: The hover functionality doesn't work until I click on the container. This only happens on some webpages.
My question is: What would cause the need to click on the container element in order for the hover functionality of its children to work? I have tried doing a focus() on the container element but it doesn't seem to make a difference.
Here is the fiddle code:
<input id="myInput" type="text"/>
<myContainer id="myContainer">
<outerThing id="outerThing">
<myThing id="myThing"></myThing>
</outerThing>
</myContainer>
<button type="button" onclick="buttonClick()">show container</button>
#myContainer {
position: absolute;
top:100px;
bottom:auto;
right:auto;
left:100px;
width:200px;
height:200px;
display: none;
background-color: red;
}
#outerThing{
width:50px;
height:50px;
margin-top: 10px;
margin-left: 10px;
display: block;
background-color: white;
}
#myThing{
width:20px;
height:20px;
margin-top: 15px;
margin-left: 15px;
display: none;
background-color: blue;
}
function buttonClick() {
document.getElementById("myInput").focus();
var cont = document.getElementById("myContainer");
cont.style.display = "block";
var outerThing = document.getElementById("outerThing");
$( outerThing ).hover(
function()
{
$(this).children(":last").css( "display", "inline-block" );
},
function()
{
$(this).children(":last").css( "display", "none" );
});
}
$(document).ready(function({
function buttonClick() {
document.getElementById("myInput").focus();
var cont = document.getElementById("myContainer");
cont.style.display = "block";
var outerThing = document.getElementById("outerThing");
$( outerThing ).hover(
function()
{
$(this).children(":last").css( "display", "inline-block" );
},
function()
{
$(this).children(":last").css( "display", "none" );
});
}
});

I made a script (using mootools library) that is supposed to overlay an image with a table grid and when each grid cell is clicked/dragged over its background color changes 'highlighting' the cell.
Current code creates a table and positions it over the element (el, image in this case). Table was used since I am planning to add rectangle select tool later on, and it seemed easiest way to do it.

There are two problems: while it works just fine in FF, IE and Chrome do not create the table if the page is refreshed. If you go back to directory root and click on the link to the file the grid table is displayed, if you hit 'refresh' button -- the script runs but the table is not injected.
Secondly, although the table HTML is injected in IE, it does not display it. I tried adding nbsp's to make sure its not ignored -- to no avail.
Any suggestions on improving code or help with the issues is appreciated.
Thanks!
Try adding a docType dec at the top of the page IE:
