Dropping a draggable in a droppable at the drop position - javascript

I have been trying to clone and drop a draggable at the position in a droppable at the coordinates where the drop happens. I have found examples online that deal with appending draggables to droppables, but they all seem to move the draggable to a specific part of the droppable on the initial drop.
Here is an example that does just that: - http://jsfiddle.net/scaillerie/njYqA/
//JavaScript from the jsfiddle
jQuery(function() {
jQuery(".component").draggable({
// use a helper-clone that is append to 'body' so is not 'contained' by a pane
helper: function() {
return jQuery(this).clone().appendTo('body').css({
'zIndex': 5
});
},
cursor: 'move',
containment: "document"
});
jQuery('.ui-layout-center').droppable({
activeClass: 'ui-state-hover',
accept: '.component',
drop: function(event, ui) {
if (!ui.draggable.hasClass("dropped"))
jQuery(this).append(jQuery(ui.draggable).clone().addClass("dropped").draggable());
}
});
});
Is there anyway I can make the draggable stay at the coordinates where the drop occured?

you must define the coordinates in the cloned element on the drop:
drop: function(event, ui) {
if (!ui.draggable.hasClass("dropped"))
var clone=jQuery(ui.draggable).clone().addClass("dropped").draggable();
clone.css('left',ui.position.left);
clone.css('top',ui.position.top);
jQuery(this).append(clone);
}
});
and also set the position absolute by css on the cloned components
.ui-layout-center .component {
position:absolute !important;
}
Here is working: http://jsfiddle.net/o2epq7p2/

Edited you code and used appendTo() and set the offset
jQuery(function() {
jQuery(".component").draggable({
// use a helper-clone that is append to 'body' so is not 'contained' by a pane
helper: function() {
return jQuery(this).clone().appendTo('body').css({
'zIndex': 5
});
},
cursor: 'move',
containment: "document"
});
jQuery('.ui-layout-center').droppable({
activeClass: 'ui-state-hover',
accept: '.component',
drop: function(event, ui) {
var _this = jQuery(this);
if (!ui.draggable.hasClass("dropped")) {
var cloned = jQuery(ui.draggable).clone().addClass("dropped").draggable();
jQuery(cloned).appendTo(this).offset({
top : ui.offset.top,
left: ui.offset.left
});
}
}
});
});

ui in the drop handler contains the dragged element's position absolute to the page. You need to transform those values to a position relative to the drop target and absolute position the cloned element inside the drop target using these values.
drop: function(e, ui) {
if (!ui.draggable.hasClass("dropped")) {
var parentOffset = jQuery('.ui-layout-center').offset();
var dropped = jQuery(ui.draggable).clone().addClass("dropped").draggable();
dropped.css('left', (ui.position.left - parentOffset.left) +'px');
dropped.css('top', (ui.position.top - parentOffset.top) +'px');
jQuery(this).append(dropped);
}
}

Adobe Edge & Javascript / jquery show element from cloned object

Hello wizards of the internet,
I want to show a hidden element from a cloned object when it is is dropped into a certain container, called "plug1". But what it does right now is it shows the hidden element on the main object and not on the cloned object. It's also not supposed to jump back to its original position. See this gif for an example.
I believe it has something to do with the sym.getSymbol("cup1").$("hold1").show(); line, but I can't put my finger on it.
Does anyone have an idea as to how I can fix this?
Script:
sym.$(function () {
sym.$("cup1").draggable({
helper: "clone",
cursor: 'move'
});
sym.$("Stage").droppable({
drop: function (event, ui) {
var $canvas = $(this);
if (!ui.draggable.hasClass('canvas-element')) {
var $canvasElement = ui.draggable.clone();
$canvasElement.addClass('canvas-element');
$canvasElement.draggable({
containment: 'Stage'
});
$canvas.append($canvasElement);
$canvasElement.css({
left: (ui.position.left),
top: (ui.position.top),
position: 'absolute'
});
sym.$("cup1").hide().clone().appendTo('Stage');
}
}
});
//hold
sym.$("plug1").droppable({
greedy: 'true',
accept: function() { return true; },
drop: function (event, ui) { tolerance: 'fit', sym.getSymbol("cup1").$("hold1").show(); }
});
});

Drag div with an <audio></audio> element

Do you know if it is possbile drag a div that have 200px and a <audio></audio> element into a droppable area, and when the div is dropped the div changes the size, to have the size according to the sound duration (1px per second for example)?
https://jsfiddle.net/hfy3dwf5/4/
code without the div size part:
$(function() {
$(".drag").draggable({
revert: 'invalid'
});
$(".drop").droppable({
drop: function( event, ui ) {
}
});
});
So if i didn't get your problem statement wrong, you could try the following
$(".drop").droppable({
drop: function(event, ui){
var audlen = $('audio').duration;
$(ui.draggable).css({width:audlen + 'px'});
}
});

Create Drag & Drop, Destory, Save Re-create - jQuery

Ok, I have an issue with drag and drop.
What they do, they click a button, it initializes the whole drag and drop.
function sortElements() {
// Place droppable elements
var x = 0;
$("#content-body div[data-type='column'],#content-body div[data-type='carousel']").each(function() {
var el = $(this);
if(x == 0){
el.before('<div class="neoDroppableEle" id="neoDroppableEle-' + x + '"><\/div>');
x++;
}
el.addClass('edit_el').after('<div class="neoDroppableEle" id="neoDroppableEle-' + x + '"><\/div>');
x++;
el.append('<div class="drag-handle"><i class="fa fa-arrows"></i></div>');
var w = el.width();
el.css('width',w+'px');
});
$("#content-body div[data-type='insertable']").each(function() {
var el = $(this);
el.prepend('<div class="neoDroppableEle" id="neoDroppableEle-' + x + '"><\/div>');
x++;
});
// Swap entire columns
$("#content-body div[data-type='column']").draggable({
refreshPositions: true,
helper: "clone",
handle:'.drag-handle',
appendTo: "body",
zIndex: 10000,
start: function( event, ui ) {
$(".neoDroppableEle").addClass('dragging');
},
stop: function( event, ui ) {
$(".neoDroppableEle").removeClass('dragging');
}
});
$(".neoDroppableEle").droppable({
accept: "div[data-type='column']",
tolerance: "pointer",
hoverClass: "focus_in",
activeClass: "focus_in_active",
drop: function(event, ui) {
cur_ele = this.id;
var el = ui.draggable;
var html = el.html();
el.remove();
$("#" + cur_ele).replaceWith('<div class="row" data-type="column">'+html+'</div>');
}
});
// Swap individual photos within columns
$("#content-body div[data-type='imagewrap']").each(function(){
$(this).draggable({
revert: "invalid",
helper: "clone" ,
zIndex: 10001,
});
$(this).droppable({
accept: "div[data-type='imagewrap']",
activeClass: "ui-state-hover",
hoverClass: "ui-state-active",
drop: function( event, ui ) {
var draggable = ui.draggable, droppable = $(this);
draggable.swap(droppable);
}
});
});
}
When they are done, they click the button again.
function sortElementsComplete() {
$(".ui-droppable").droppable("destroy");
$(".ui-draggable").draggable("destroy");
$(".edit_el").removeAttr('style').removeClass('edit_el');
$(".neoDroppableEle").remove();
$(".drag-handle").remove();
}
This all runs and works great!
But now I am tryng to save the HTML code after each drop for undo's. And when I save the undo, I need to remove all additional classes and elements my function to drag and drop add's. Because they may not be in the sorting area when they click undo and do not want drag handles and my borders I set up as visual aids just appearing.
So now I have:
$(".neoDroppableEle").droppable({
accept: "div[data-type='column']",
tolerance: "pointer",
hoverClass: "focus_in",
activeClass: "focus_in_active",
drop: function(event, ui) {
cur_ele = this.id;
var el = ui.draggable;
var html = el.html();
el.remove();
$("#" + cur_ele).replaceWith('<div class="row" data-type="column">'+html+'</div>');
setTimeout(function(){
sortElementsComplete();
editor_add();
},1000);
}
});
The above with the timeout code always fails with:
Error: cannot call methods on droppable prior to initialization;
attempted to call method 'destroy'
How so? It IS initialized and running. After the drop I should be able to destroy it, make my save and rebuild it. Using disable gives the same error. To me the error makes no sense.
After editor_add() is ran, it re-builds whatever they were doing, in this case it will fire sortElements(); after the save.
But the below runs fine?
// Swap individual photos within columns
$(this).droppable({
accept: "div[data-type='imagewrap']",
activeClass: "ui-state-hover",
hoverClass: "ui-state-active",
drop: function( event, ui ) {
var draggable = ui.draggable, droppable = $(this);
draggable.swap(droppable);
setTimeout(function(){
sortElementsComplete();
editor_add();
},250);
}
});
It will error if I do not have the timeout above. Seems 250 is the min, anything lower it errors. But the first one will not ever work, no matter how long or short I make the timeout.
Really hope this makes sense.
Maybe if I used
var draggable = ui.draggable, droppable = $(this);
draggable.swap(droppable);
On it instead it would work. o.O

jQuery - drag and drop of cloned element

I have a cloned element which I am able to drag however I wish to drop it in a specific div element and if valid not revert back to its original position, however it is always reverting back to its original position whether it is valid or not.
I am currently using the code below:
$("ul#objectsList li").draggable({
revert: 'invalid',
snap: "#objectsDropBox",
snapMode: "inner",
helper: function() { return $(this).clone().appendTo('body').show(); },
start: function(e, ui) { $(ui.helper).addClass("ui-draggable-helper");}
});
$("#objectsDropBox").droppable({
accept: "ul#objectsList li",
drop: function( event, ui ) {
alert('hi');
}
});
Why is it not staying in the div when a valid draggable is dropped?
Try this
$("#objectsDropBox").droppable({
accept: "ul#objectsList li",
drop: function (event, ui) {
$(this).append(ui.draggable);
//if you want to retain the element use ui.draggable.html() or clone it.
}
});

Only allowing one droppable area jquery drag and drop

I have jquery drag and drop working so I can move one row in a table to another.
the demo is here:
http://www.aussiehaulage.com.au/Default.aspx
I use jquery-ui-1.8.22 to make my table draggable/droppable.
My javascript is :
$(document).ready(function () {
$(".draggable").draggable({
helper: function () { return "<div class='ghost'></div>"; },
start: resizeGhost,
revert: 'invalid'
});
$(".droppable").droppable({
hoverClass: 'active',
drop: function (event, ui) {
var target = $(event.target);
var draggable = ui.draggable;
draggable.insertBefore(target);
},
tolerance: 'touch'
});
});
However when i move the row, if the mouse cursor is in between 2 rows on the droppable table both droppable rows are highlighted.. I need to make it so it will only highlight 1 droppable row at a time..
is this possible?
Add a new option in your droppable element, using either tolerance fit or intersect
$(".droppable").droppable({
hoverClass: 'active',
tolerence: 'intersect',
drop: function (event, ui) {
var target = $(event.target);
var draggable = ui.draggable;
draggable.insertBefore(target);
},
tolerance: 'touch'
});
And for your reference: jquery-ui
