Move a div to a drop position

Apologies in advance if I am bad at describing this problem... hope you can still understand it.
Right now I have a Div that has its display set to 'none'.
When I drag and drop a button on the screen, it will then add a class to unhide the div.
Those above work fine, but what I cannot figure out is how to have the div appear exactly at where I dropped the button, rather than always appearing at a fixed location in the middle of the screen (which is what it is doing right now).
Would appreciate any help I can get! Here is the part of the javascript I am using (please let me know if this isn't sufficient info):
$(document).ready(function() {
$('.js-hotspot').draggable({
helper: "clone",
revert: false,
start: function(event, ui) {
console.log("Started");
},
stop: function(event, ui) {
addAnyHotspot();
$( ".hotspot-tooltip" ).addClass( "open" ); //Unhide the div
}
});
});

I managed to solve it. This is my new code:
$(document).ready(function() {
$('.js-hotspot').draggable({
helper: "clone",
revert: false,
start: function(event, ui) {
console.log("Started");
$(document).ready(function() {
$(this).on("drag", function(e) {
var x = e.pageX;
var y = e.pageY;
var el = $("#meh"); //assign #meh to the div that needs to be opened
el.css('position', 'absolute');
el.css("left", x);
el.css("top", y);
console.log("Shifted Position");
})
});
},
stop: function(event, ui) {
addAnyHotspot();
console.log("AddAnyHotSpot");
$( ".hotspot-tooltip" ).addClass( "open" );
}
});
});

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 sortable - limit droppables

I will simplify my explanation so you get what I am doing. I have two div's and I set up portlets as shown here, however I am dynamically injecting my portlets, no big problem there.
<div id="mainallapplicant" class="myrow"></div>
<div id="contingent_right" class="myrow"></div>
Here is the JavaScript
$( ".myrow" ).sortable({
connectWith: ".myrow",
revert: true,
beforeStop: function( event, ui ) {}
});
I am trying to allow a maximum of only one droppable into mainallapplicant. If there is one already there, I will show a confirmation dialog and depending on the answer, I cancel the drop or move out the existing item and replace it with the new item. I tried the following but I am getting nowhere.
$( ".myrow" ).sortable({
connectWith: ".myrow",
revert: true,
start: function(event, ui) {
if ($(this).prev().find(".portlet").length == 1) {
ui.sender.draggable("cancel");
}
},
stop: function(event, ui) {
if ($(this).prev().find(".portlet").length == 1) {
ui.item.remove();
// Show an error...
}
}
});

You can use start to get the current count of portlet elements, then use stop to do the checking
Also notice I added class names to each div to allow only one div to have a maximum of 1 portlet
$(document).ready(function () {
$.count = 0;
$(".myrow").sortable({
connectWith: ".myrow",
revert: true,
start: function () {
$.count = $(".myrow").has(".portlet").length;
console.log("Start " + $.count);
},
stop: function (event, ui) {
if ($(ui.item).parent(".myrow").hasClass("left")) {
if ($.count == 2) {
$(".myrow").sortable("cancel");
}
}
}
});
});

How to track the id of draggable div id in drop function

I have to find the id of draggable div in drop function using javascript. Using Jquery i know how to find it. but i am stuck in one condition where id of the dragged event is necessary in drop function. In drag function I am able to get id by using alert("id "+obj.id) but please help me out to find this in drop function using javascript.
Here is the code
function allowDrop(ev)
{
ev.preventDefault();
}
function drag(ev, obj)
{
ev.dataTransfer.setData("Text",ev.target.id);
alert("id "+obj.id)
}
function drop(ev)
{
farea1[i] = x[0].getElementsByTagName("termTxt")[i].getAttribute("correctCat");
ev.preventDefault();
var data=ev.dataTransfer.getData("Text");
ev.target.appendChild(document.getElementById(data));
i++;
display();
if(ev.target.id == "area1"){
fans1[n]=farea1[k];
k++;
n++;
countarea1++;
}
}

Use this function to find the droppable id
$(function() {
$( "#droppable" ).droppable({
drop: function( event, ui ) {
$( this ).html( "Dropped in " + this.id );
}
});
});

You should be able to get that target div ID by :
$(".droppable").droppable({
drop: function(event, ui) {
$('.display').html("Dropped in " + this.id);
},
over: function(event, ui) {
$('.display').html( this.id );
}
});

jQuery Drag and Drop not working

I am trying to develop a simple drag and drop 'game'. In simple terms all you do is drag and drop various items into a area and it will say correct or wrong depending on the item dragged. This is what I have so far and its not working at all and I dont know why. My knowledge of JS and jQuery leaves a lot to be desired too.
<script>
$(function() {
$( "#draggable" ).draggable();
$( "#wrong" ).draggable();
$( "#droppable" ).droppable({
drop: function( event, ui ) {
var currentId = $(this).attr('id');
if (currentId == "draggable") {
$( this )
.addClass( "highlight" )
.find( "p" )
.html( "Correct! :)" );
} else {
$( this )
.find( "p" )
.html( "Wrong! :(" );
}
}
});
});
</script>
Now that I have it working I need more instances of the draggable images but when I add more the the new ones that have been added don't work.
http://jsfiddle.net/KcruJ/9/

var currentId = $(this).attr('id');
if (currentId == "draggable")
...
Will never result true, as $(this) represents the droppable the draggable is dropped on. ui.draggable represents the draggable[1]
Try:
var currentId = $(ui.draggable).attr('id');
if (currentId == "draggable")
...

This works: http://jsfiddle.net/T6nu3/2/
$(this).attr('id');
Will always return droppable.
You need to access the dragged element:
$(ui.draggable).attr('id');
Take a look at the jQuery UI Documentation for more information.
Code:
$(function() {
$("#draggable").draggable();
$("#wrong").draggable();
$("#droppable").droppable({
drop: function(event, ui) {
var currentId = $(ui.draggable).attr('id');
if (currentId == "draggable") {
$(this).addClass("highlight").find("p").html("Correct! :)");
} else {
$(this).find("p").html("Wrong! :(");
}
}
});
});

haha well, Alex seems to have this one on lock.
There's the answer: http://jsfiddle.net/aGqHh/1/
