draggable droppable with sortable

we trying to integrate multiple drggable and droppable. we are using sortable for ease of clone functionality in this scenario. draggable once dropped need to be draggable again.
how do we limit sortable to receive only one element and revert to original if more than one dropped onto it.
look like out and over functions of sortable are misbehaving in that case.
commented line code is for disabling dropping second element on sortable. which is not working as expected.
Two issues when you enable my commented code:
draggable clone not reverting to original place after moving out of droppable.
draggable element moved from one droppable to another reverting to draggable's original place.
For a demonstration, see this jsfiddle
script:
// jQuery.noConflict();
jQuery( document ).ready(function() { init();});
function init() {
var mouse_button = false;
jQuery('.ui-draggable').live({
mousedown: function () {
mouse_button = true;
},
mouseup: function () {
if (jQuery(this).attr('data-pos') == 'out' && jQuery(this).attr('data-id')) {
var p = jQuery('#' + jQuery(this).attr('data-id'));
var offset = p.offset();
jQuery(this).hide();
jQuery(this).animate({ left: offset.left, top: offset.top, width: jQuery(this).width, height: jQuery(this).height }, 100, function () {
jQuery(this).remove();
$( ".ui-droppable" ).each(function() {
if($(this).children().length == 0) {
$( this ).removeClass("dontDrop");
}
});
//if(p[0].hasAttribute("draggable"))
p.draggable("enable");
// $('.ui-droppable').sortable('option', 'connectWith',$('.ui-droppable').not('.dontDrop'));
// $('.ui-draggable').draggable('option', 'connectToSortable',$('.ui-droppable').not('.dontDrop'));
});
}
mouse_button = false;
},
mouseout: function () {
if (mouse_button) {
mouse_button = false;
}
}
});
jQuery( '.ui-draggable' ).draggable( {
cursor: 'move',
helper: 'clone',
connectToSortable: ".ui-droppable",
revert: function (event, ui) {
}
} );
jQuery(".ui-droppable").sortable({
cursor: "move",
connectWith: ".ui-droppable",
receive: function (event, ui) {
if($(this).children().length >= 1) {
$(this).children().addClass('filled');
$(this).addClass('dontDrop');
$( ".ui-droppable" ).each(function() {
if($(this).children().length == 0) {
$( this ).removeClass("dontDrop");
}
});
// $('.ui-droppable').sortable('option', 'connectWith',$('.ui-droppable').not('.dontDrop'));
// $('.ui-draggable').draggable('option', 'connectToSortable',$('.ui-droppable').not('.dontDrop'));
}else {
$(this).children().removeClass('filled');
}
if (jQuery(this).data().sortable.currentItem) {
jQuery(this).data().sortable.currentItem.attr('data-id', jQuery(ui.item).attr("id"));
// if(jQuery(ui.item)[0].hasAttribute("draggable"))
jQuery(ui.item).draggable("disable");
}
},
out: function (event, ui) { if (ui.helper) { ui.helper.attr('data-pos', 'out'); } },
over: function (event, ui) { ui.helper.attr('data-pos', 'in'); }
});
}

Here's a working example: click here
You can user Jquery's draggable and droppable interactions to achieve what you want. Check the working example.
$(document).ready(function () {
$(".ui-draggable").draggable(draggable_options) //make cards draggable
$(".ui-droppable").droppable({ //handle card drops
greedy: true,
drop: function (event, ui) {
handleDrop(this, event, ui)
},
accept: function () {
return checkIfShouldAcceptTheDraggable(this)
}
})
})

You can do it like this:(Online Demo (fiddle))
var draggable_options = {
helper: 'clone',
cursor: 'move',
revert: 'invalid',
};
$(".ui-draggable").draggable(draggable_options);
$(".ui-droppable").droppable({
drop: function(event, ui) {
var $item = ui.draggable;
$item.draggable(draggable_options)
$item.attr('style', '')
$(this).append($item)
},
accept: function() {
return $(this).find("li").length === 0 // Your condition
}
});
$(".textToImageRightPanel").droppable({
drop: function(event, ui) {
var $item = ui.draggable;
$item.draggable(draggable_options);
$item.attr('style', '');
// Return to older place in list
returnToOlderPlace($item);
}
});
// Return item by drop in older div by data-tabidx
function returnToOlderPlace($item) {
var indexItem = $item.attr('data-tabidx');
var itemList = $(".textToImageRightPanel").find('li').filter(function() {
return $(this).attr('data-tabidx') < indexItem
});
if (itemList.length === 0)
$("#cardPile").find('ul').prepend($item);
else
itemList.last().after($item);
}

Determining when to revert may be best done in .draggable() using revert: function(){}.
Function: A function to determine whether the element should revert to its start position. The function must return true to revert the element.
You can do this:
jQuery('.ui-draggable').draggable({
cursor: 'move',
helper: 'clone',
connectToSortable: ".ui-droppable",
revert: function(item) {
if (!item) {
return true;
} else {
if (item.hasClass("dontDrop")) {
return true;
}
}
return false;
}
});
the revert function is passed false if the draggable item is not accepted. For example, if it is dropped on something that is not a target. If the draggable item is accepted, a jQuery Object is passed back.
See more: jQueryUI sortable,draggable revert event
The logic is a little confusing. If what is passed back is false, we return true to revert letting draggable revert the item to it's position. If what is passed back is not false, then it's an object we can test. If the target is "full", we revert. Otherwise we do not revert.
Sortable still wants add the item for some reason. May need to adjust to update and clear out any items that are not class "filled".

jQuery UI - drag an item from drop area and drop it back to same drop area - drop event doesn't fired

I have number of drop areas $('.drophere') and a storage of draggables $('.dragme').
Each drop area can contain just one dropped item.
You can drop new item over dropped one (replace). You can drag an item from one drop area to other.
If you start drag an item from drop area and decided drop it back to same area - drop event is not fired, thus the dragged item is lost.
Here is simplified code:
var draggedData;
$('.drophere').droppable({
drop: function (event, ui) {
$(this).attr('data-text', draggedData);
$(this).draggable('enable');
}
}).draggable({
disabled: true,
helper: "clone",
start: function (event, ui) {
draggedData = $(this).attr('data-text');
$(this).attr('data-text', "").draggable('disable');
}
});
$('.dragme').draggable({
helper: "clone",
start: function (event, ui) {
draggedData = $(this).attr('data-text');
}
});
Is it some kind of restriction in jQuery UI droppable? Is any way to "forget" the origins of such dragged item? Thank you.
just added: http://jsfiddle.net/gpnpwwbw/

Taking advantage of jQuery Draggables Stop event I came up with the following solution:
var draggedData,
dropLastDragged
startPosData = {};
function checkIntersect(posData){
var left = startPosData.left,
top = startPosData.top,
right = startPosData.left+startPosData.width,
bottom = startPosData.top+startPosData.height,
cornerLeftPos = posData.left,
cornerTopPos = posData.top;
cornerLeftPos += startPosData.width/2;
cornerTopPos += startPosData.height/2;
if((cornerLeftPos > left && cornerLeftPos < right) && (cornerTopPos > top && cornerTopPos < bottom)){
return true;
}
return false;
}
$('.drophere').droppable({
drop: function (event, ui) {
dropLastDragged = false;
$(this).html(draggedData);
$(this).draggable('enable');
}
}).draggable({
disabled: true,
helper: "clone",
start: function (event, ui) {
startPosData.left = ui.offset.left;
startPosData.width = $(this).width();
startPosData.top = ui.offset.top;
startPosData.height = $(this).height();
draggedData = $(this).html();
$(this).html('Drop here').draggable('disable');
dropLastDragged = this;
},
stop: function(event, ui) {
if(dropLastDragged){
if(checkIntersect(ui.offset)){
$(dropLastDragged).html(ui.helper.html());
$(dropLastDragged).draggable('enable');
}
}
}
});
$('.dragme').draggable({
helper: "clone",
start: function (event, ui) {
draggedData = $(this).html();
}
});

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

How will we get the id of a particular <ul> in jquery?

This is the jquery function which makes the ul draggable and and a particular area droppable.
//Jquery
$(function () {
// there's the gallery5 and the trash
var $gallery5 = $("#gallery5"),
$trash = $("#trash");
// let the gallery5 items be draggable
$("ul", $gallery5).draggable({
cancel: "a.ui-icon", // clicking an icon won't initiate dragging
revert: "invalid", // when not dropped, the item will revert back to its initial position
containment: "document",
helper: "clone",
cursor: "move",
});
// let the trash be droppable, accepting the gallery items
$trash.droppable({
accept: "#gallery > li",
accept: "#gallery2 > li",
activeClass: "ui-state-highlight",
drop: function (event, ui) {
alert("trash");
deleteImage(ui.draggable);
}
});
// let the gallery be droppable as well, accepting items from the trash
$gallery5.droppable({
accept: "#gallery li , #gallery2 li , #gallery4 li , #gallery3 li",
activeClass: "custom-state-active",
drop: function (event, ui) {
alert("gallery5");
recycleImage(ui.draggable);
}
});
// image deletion function
var recycle_icon = "<a href='link/to/recycle/script/when/we/have/js/off' title='Recycle this image' class='ui-icon ui-icon-refresh'>Recycle image</a>";
// image recycle function
var trash_icon = "<a href='link/to/trash/script/when/we/have/js/off' title='Delete this image' class='ui-icon ui-icon-trash'>Delete image</a>";
function recycleImage ($item) {
// alert("recycleImage");
$item.fadeOut(function () {
$item
.find("a.ui-icon-refresh")
.remove()
.end()
.css("width", "250px")
.find("img")
.css("height", "50px")
.end()
.fadeIn()
.appendTo($gallery5);
});
}
// image preview function, demonstrating the ui.dialog used as a modal window
});
This is called in a loop and the data is coming from the database.
//BODY
<ul id=coming from database>
<li>
description
id
</li>
</ul>
There are multiple uls in the output. I want to check the id of that particular ul which i am dragging.
Thanx.

jQuery
$('ul').each(function(){
var ulID = $(this).attr('id');
});
This will get the ID from each ul, you can then do what you need with it . . .

Have you ever try this:
var ids = '';
$('ul').each(function(){
ids += $(this).attr('id');
});

Try this:
$('ul').each(function()
{
var ids= $(this).attr('id'); // This is your rel value
});

Jquery Drag and Drop with multiple Drop placeholders and reset option

im trying to develop a game using jquery drag and drop and need help on it. The problem i am facing is that there are 4 drop location and about 25 dragable elements. Each drop location can have only one draggable element and if i try to drop another element the location should be swapped and previously dropped element will get the initial location of newly dragged element.
