Jquery drag and drop multiple items without removing source items - javascript

I have two lists (div or table elements) in which I can drag & drop items from one to the other, and its working fine. But I want a to drop a copy of selected items form source div NOT removing it from the source list.
Any solution?
HTML Code:
<div class="demo">
<p>Available Boxes (click to select multiple boxes)</p>
<ul id="draggable">
<li>Box #1</li>
<li>Box #2</li>
<li>Box #3</li>
<li>Box #4</li>
</ul>
<p>My Boxes</p>
<ul id="droppable">
</ul>
</div>
Jquery Code:
$(document).ready(function() {
var selectedClass = 'ui-state-highlight',
clickDelay = 600,
// click time (milliseconds)
lastClick, diffClick; // timestamps
$("#draggable li")
// Script to deferentiate a click from a mousedown for drag event
.bind('mousedown mouseup', function(e) {
if (e.type == "mousedown") {
lastClick = e.timeStamp; // get mousedown time
} else {
diffClick = e.timeStamp - lastClick;
if (diffClick < clickDelay) {
// add selected class to group draggable objects
$(this).toggleClass(selectedClass);
}
}
})
.draggable({
revertDuration: 10,
// grouped items animate separately, so leave this number low
containment: '.demo',
start: function(e, ui) {
ui.helper.addClass(selectedClass);
},
stop: function(e, ui) {
// reset group positions
$('.' + selectedClass).css({
top: 0,
left: 0
});
},
drag: function(e, ui) {
// set selected group position to main dragged object
// this works because the position is relative to the starting position
$('.' + selectedClass).css({
top: ui.position.top,
left: ui.position.left
});
}
});
$("#droppable, #draggable").sortable().droppable({
drop: function(e, ui) {
$('.' + selectedClass).appendTo($(this)).add(ui.draggable) // ui.draggable is appended by the script, so add it after
.removeClass(selectedClass).css({
top: 0,
left: 0
});
}
});
});

Drag and Drop serialize items

I'm trying to make an exam application which has drag & drop question type that the user might dragging correct elements to correct droppable boxes. Totally, I need get dropped elements/items id's as array or another and insert to mysql with php. I did something are below:
Javascript
$(".dragging-items .draggable-item").draggable({
helper: "clone",
opacity: 0.5,
scroll:true,
refreshPositions: true,
start: function( event, ui ) {
(this).addClass("dragging");
},
stop: function( event, ui ) {
$(this).removeClass("dragging");
},
});
$(".dragging-items").droppable({
hoverClass: "drop-hover",
drop:function(event, ui) {
ui.draggable.detach().appendTo($(this));
}
});
$(".droppable-list").droppable({
drop:function(event, ui) {
ui.draggable.detach().appendTo($(this));
var drag_id = $(ui.draggable).attr("id");
var drop_id = event.target.id;
var $tbox = $("input[name=droppable-list-"+ drop_id +"]");
var current_data = $tbox.val();
var new_data = current_data + drag_id + ", ";
$tbox.val(new_data);
},
});

I found a number of oddities in CSS that may want to be corrected. A lot of missed ;, but that's not the main focus. Also, you have a number of repeated ID attributes and these must be unique in HTML. Consider the following code.
$(function() {
function dropToArray(dropObj) {
var results = [];
$(".draggable-item", dropObj).each(function(i, el) {
results.push($(el).data("drag-id"));
});
return results;
}
function updateDropList(dropObj) {
var dropped = dropToArray(dropObj);
var $tbox = $("input[name=droppable-list-" + dropObj.attr("id") + "]");
$tbox.val(dropped.join(","));
}
$(".dragging-items .draggable-item").draggable({
helper: "clone",
opacity: 0.5,
scroll: true,
refreshPositions: true,
start: function(event, ui) {
$(this).addClass("dragging");
},
stop: function(event, ui) {
$(this).removeClass("dragging");
},
});
$(".dragging-items").droppable({
hoverClass: "drop-hover",
drop: function(event, ui) {
ui.draggable.detach().appendTo($(this));
}
});
$(".droppable-list").droppable({
drop: function(event, ui) {
var $this = $(this);
if ($this.find(".droppable-list").length >= 2) {
ui.draggable.draggable("option", "revert", true);
return;
} else {
ui.draggable.detach().appendTo($(this));
setInterval(function() {
$(".droppable-list").each(function(i, el) {
updateDropList($(el));
});
}, 100);
}
},
});
});
Always best to create a few simple functions if you're going to be doing something often. I created two, one to iterate the container and build an array of the specific ID. To help ensure the same data comes back, I added the data-drag-id attribute. Now we can have unique IDs and still retain the ID Number for each item.
Working example: https://jsfiddle.net/Twisty/t1a40Lsn/22/
As you can see, when an item is dragged and dropped, it updates the field for all the lists. This addresses an issue if the user moves it from one box to another. Since the data is in an Array, we can simple use .join() to make a nice well formatted string of data.

How to not duplicate the element on removal of Multi-Select Drag

Good day everyone,
Given the following JSfiddle snippet: http://jsfiddle.net/abUF2/
How would it be possible to not copy back the elements from the right side to the left side when removing them from the right side (i.e. just making them disappear instead of copy back)?
Thank you very much for your help.

item.data('multidrag', elements).siblings('.selected').remove();

jQuery - creating a new draggable div on mousedown which can then be dragged in the same action

I want to dynamically create a draggable div on mousedown, which within the same mousedown event can then be dragged into a droppable area and dropped.
The point that I have got to so far is that a new draggable div is created on mousedown and that div then follows the cursor. But it cannot be dropped into the droppable area.
JS Fiddle here - http://jsfiddle.net/rqyv6bpg/
The jQuery code:
jQuery(document).ready(function ($) {
//on mousedown, creates a new draggable div in the cursor position
$(".search-result-container").mousedown(function(e){
var x = e.pageX + 'px';
var y = e.pageY + 'px';
$('<div/>', {
"class": "test",
text: "Draggable track that can be dropped into droppable queue!",
}).css({
"position": "absolute",
"left": x,
"top": y,
"z-index": 1000
}).draggable()
.appendTo($(document.body))
});
//in order to get the newly created div to instantly follow the cursor
$(document).on('mousemove', function(e){
$('.test').css({
left: e.pageX,
top: e.pageY
});
});
$( "#queue-bar" ).droppable();
});
Help would be greatly appreciated! Thanks in advance.
If I understood correctly, you are looking for the helper option of draggable widget.
$(document).ready(function($) {
$(".search-result-container").draggable({
helper: "clone", // use a clone for the visual effect
revert: false
});
$("#queue-bar").droppable({
accept: "article",
drop: function(event, ui) {
ui.draggable.clone().appendTo(this); // actually append a clone to the droppable
}
});
});
$(document).ready(function($) {
$(".search-result-container").draggable({
helper: "clone", // use a clone for the visual effect
revert: false
});
$("#queue-bar").droppable({
accept: "article",
drop: function(event, ui) {
ui.draggable.clone().appendTo(this); // actually append a clone to the droppable
}
});
});
.search-result-container {
background-color: red
}
#queue-bar {
background-color: blue
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
<article class="search-result-container">This is a track with lots of information</article>
<div id="queue-bar">This is the droppable area</div>
You can also create a custom helper by returning an element to be used as helper as shown below:
$(document).ready(function($) {
$(".search-result-container").draggable({
helper: function(){
// return a custom element to be used for dragging
return $("<div/>",{
text: $(this).text(),
class:"copy"
})
}, // use a clone for the visual effect
revert: false
});
$("#queue-bar").droppable({
accept: "article",
drop: function(event, ui) {
//you might want to reset the css using attr("style","")
ui.helper.clone().appendTo(this); // actually append a clone of helper to the droppable
}
});
});
.search-result-container {
background-color: red;
}
#queue-bar {
background-color: blue;
}
.copy{
background-color: green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
<article class="search-result-container">This is a track with lots of information</article>
<div id="queue-bar">This is the droppable area</div>
Updated your fiddle, it works now!!
http://jsfiddle.net/rqyv6bpg/2/
Here is the JS code:
$( ".text" ).draggable({helper:'clone'});
$( "#queue-bar" ).droppable({
drop: function( event, ui ) {
$( this ).append( "<br/>"+ui.draggable.html() );
}
});

How to prevent child sortables from cloning

I have three sortable list boxes, one grey and two yellow. I can drag and clone child sortable li's into the bottom yellow lists no problem.
The problem is that once the child clone li's from the grey list box are placed into the yellow list boxes, you can no longer drag/shift them within the containing yellow list box or to the adjacent yellow list box. They just clone continuously when you attempt to drag them elsewhere.
I would like to drag and clone sortables from the grey list box into the yellow boxes and have the cloned child li's be able to drag and move within the yellow lists boxes without cloning.
How can I prevent the child li's from cloning. Any help would be much appreciated. Thanks.

$(function() {
$(".sortable").sortable(
{
helper : "clone",
connectWith : ".sortable",
start : function(event,ui)
{
$(ui.item).show();
clone = $(ui.item).clone();
before = $(ui.item).prev();
position = $(ui.item).index();

else before.after(clone);

});
$(".sortable").sortable();
});
You can set a particular behavior for the first list and a different for the others, the others can't interact with the first using a coonectWith selector with :not selector.
Code:
$(function () {
$("#sortable1").sortable({
helper: "clone",
connectWith: ".sortable",
start: function (event, ui) {
$(ui.item).show();
clone = $(ui.item).clone();
before = $(ui.item).prev();
position = $(ui.item).index();
},
beforeStop: function (event, ui) {
if ($(ui.item).closest('ul#sortable1').length > 0) $(this).sortable('cancel');
},
stop: function (event, ui) {
if (position == 0) $("#sortable1").prepend(clone);
else before.after(clone);
}
});
$(".sortable").sortable({connectWith: ".sortable:not('#sortable1')"});
});

Sort multiple selected items in jQuery sortable?

I'm trying to select more than one item in a jQuery sortable set and then move the selected items around together.
Here's my weak beginning of an attempt to make it work. And here's the code:
HTML:
<div class="container">
<div>one</div>
<div>two</div>
<div>three</div>
<div>four</div>
<div>five</div>
</div>
JS:
$('.container div').draggable({
connectToSortable: '.container',
//How do I drag all selected items?
helper: function(e, ui) {
return $('.selected');
}
});
$('.container').sortable({
axis: 'y',
//How do I sort all selected items?
helper: function(e, ui) {
return $('.selected');
}
});
$('.container div').live('click', function(e) {
$(this).toggleClass('selected');
});
CSS:
body{background-color:#012;font-family:sans-serif;text-align:center;}
div{margin:5px 0;padding:1em;}
.container{width:52%;margin:1in auto;background-color:#555;border-radius:.5em;box-shadow:0 0 20px black;}
.container div{background-color:#333;color:#aaa;border:1px solid #777;background-color:#333;color:#aaa;border-radius:.25em;cursor:default;height:1em;}
.container div:hover{background-color:#383838;color:#ccc;}
.selected{background-color:#36a !important;border-color:#036 !important;color:#fff !important;font-weight:bolder;}
I don't know if I'm headed in the right direction or not. I can't find an example of this anywhere online. Just lots of related questions. Does anyone know how?
For example, if I've selected items 4 and 5 out of a list of 6. I want to be able to drag 4 and 5 to the top of the set to get this order - 4 5 1 2 3 6 - Or if I selected 5 and 1 and drag them to the bottom - 2 3 4 6 1 5
This seems to work with the multisortable plugin. Code below. Or see jsFiddle.
// ctrl + click to select multiple
$('.container').multisortable({
stop: function(e, ui) {
var $group = $('.ui-multisort-grouped').not(ui.item);
$group.clone().insertAfter($(ui.item));
$group.each(function() {
$(this).removeClass('ui-multisort-grouped');
});
$group.remove();
}
});
But what if multisortable breaks with future jQuery versions?
Modifying my answer here (according to your HTML and CSS) :
Select items to sort
Create a custom helper
Hide the selected items until sort is done
Resize the helper and placeholder according to the selection
Manually detach selected items from the current position and attach them to the new position after sort
Show the hidden items (undo step 3) after step5
$(function () {
$('.container').on('click', 'div', function () {
$(this).toggleClass('selected');
});
$(".container").sortable({
revert: true,
helper: function (e, item) {
if (!item.hasClass('selected')) item.addClass('selected');
var elements = $('.selected').not('.ui-sortable-placeholder').clone();
var helper = $('<div/>');
item.siblings('.selected').addClass('hidden');
return helper.append(elements);
},
start: function (e, ui) {
var elements = ui.item.siblings('.selected.hidden').not('.ui-sortable-placeholder');
ui.item.data('items', elements);
var len = ui.helper.children().length;
var currentHeight = ui.helper.height()
var itemHeight = ui.item.height() + 32; // 32 = 16x2 padding
ui.helper.height(currentHeight + (len * itemHeight))
ui.placeholder.height((len * itemHeight))
},
receive: function (e, ui) {
ui.item.before(ui.item.data('items'));
},
stop: function (e, ui) {
ui.item.siblings('.selected').removeClass('hidden');
$('.selected').removeClass('selected');
}
});
});
