Drop element centered on mouse position - javascript

I have a container where I want to drop an image from a menu below but when I drop it at the main container I cannot get the proper position, it seems it is dropped randomly in the container. How can I get the item dropped centered at mouse position?
var x = null;
$(function() {
$(".piece").draggable({
cancel: "a.ui-icon",
revert: "invalid",
helper: 'clone',
containment: '#container',
});
$(".piece").droppable({
accept: ".cap",
drop: function(event, ui) {
x = ui.helper.clone();
x.appendTo(this);
}
});
$(".cap").draggable({
cancel: "a.ui-icon",
helper: 'clone'
});
$("#container").droppable({
accept: ".piece",
drop: function(event, ui) {
x = $('<div/>');
x.addClass('piece-div');
x.css('top', ui.position.top);
x.css('left', ui.position.left);
x.draggable({
containment: '#container',
cursor: 'move',
});
x.appendTo(this);
x.droppable({
accept: ".cap",
drop: function(event, ui) {
var y = $('<img />');
y.attr('src', ui.helper.attr('src'));
y.css('top', ui.offset.top);
y.css('left', ui.offset.left);
y.appendTo(this);
}
});
ui.helper.remove();
}
});
});
I expect the four colored piece to be dropped centered at mouse position in the grey container but it gets dropped almost randomly. Here is a fiddle:

Looks like you might just need to adjust your settings a little. These %'s work in the fiddle but you may need to adjust them with better CSS for your end purpose:
$("#container").droppable({
accept: ".piece",
drop: function(event, ui) {
x = $('<div/>');
x.addClass('piece-div');
x.css('top', '15%'); // Change this to some %
x.css('left','35%'); // Change this to some %
x.draggable({
containment: '#container',
cursor: 'move',
});

drag and drop element to any location?

I have two issues,
I am able to move div element once dropped in RED div, but if I try to reposition the element code messes up.
I want to save position X/Y & ID of div moved to RED Div on SAVE button Click.
$(".draggable").draggable({ cursor: "crosshair", revert: "invalid"});
$("#drop").droppable({ accept: ".draggable",
drop: function(event, ui) {
console.log("drop");
$(this).removeClass("border").removeClass("over");
var dropped = ui.draggable;
var droppedOn = $(this);
$(dropped).detach().css({}).appendTo(droppedOn);
},
over: function(event, elem) {
$(this).addClass("over");
console.log("over");
}
,
out: function(event, elem) {
$(this).removeClass("over");
}
});
$("#drop").sortable();
$("#origin").droppable({ accept: ".draggable", drop: function(event, ui) {
console.log("drop");
$(this).removeClass("border").removeClass("over");
var dropped = ui.draggable;
var droppedOn = $(this);
$(dropped).detach().css({top: 0,left: 0}).appendTo(droppedOn);
}});
$(".save").click(function() {
getCordinates();
});
function getCordinates(){
var c = document.getElementById("drop").children.length;
alert(c);
}
Fiddler link for the code: Code Fiddler
The first point I could not replicate it, regarding to the second point you can obtain the id in the event drop of your div (#origin or #drop) like this:
$(ui.draggable).attr("id")
and the X and Y Position of the img has been dropped you can obtain this way:
//position X
$(ui.draggable).offset().left
//Position Y
$(ui.draggable).offset().top

how to make a div draggable and droppable

One thing left in my project was to make the two divs draggable and droppable simultaneously. Now I have the working code of divs that can be dragged and dropped but for example I can drag a div from target area and drop it on users area but I cant seem to figure out a way to drag those divs from users and assign to different users.
$(document).ready(function(){
$(".dragable").draggable({
cancel: "a.ui-icon",
revert: true,
helper: "clone",
cursor: "move",
revertDuration: 0
});
$('.droppable').droppable({
accept: ".dragable",
activeClass: "ui-state-highlight",
drop: function( event, ui ) {
// clone item to retain in original "list"
var $item = ui.draggable.clone();
$(this).addClass('has-drop').append($item);
}
});
});
http://jsfiddle.net/coder880/TpbZk/31/
The issue is because once the item is dragged/dropped it is then cloned. This clone does not have the draggable() plugin instantiated on it. You need to call draggable() on the $item again. Try this:
var draggableOptions = {
cancel: "a.ui-icon",
revert: true,
helper: "clone",
cursor: "move",
revertDuration: 0
}
$(".dragable").draggable(draggableOptions);
$('.droppable').droppable({
accept: ".dragable",
activeClass: "ui-state-highlight",
drop: function(event, ui) {
var $item = ui.draggable.clone();
$item.draggable(draggableOptions);
$(this).addClass('has-drop').append($item);
}
});
Updated fiddle
it should only be cloned when its from target otherwise it should move it.
To achieve this you need to remove the helper: 'clone' option in the cloned draggable element and maintain a flag on the element to determine whether it is a brand new clone or has been dragged previously and moved again. To do this you could use a class, something like this:
$(".dragable").draggable({
cancel: "a.ui-icon",
revert: true,
helper: "clone",
cursor: "move",
revertDuration: 0
});
$('.droppable').droppable({
accept: ".dragable",
activeClass: "ui-state-highlight",
drop: function(event, ui) {
var $item = $(ui.draggable)
if (!$item.hasClass('clone')) {
$item = $item.clone().addClass('clone');
$item.draggable({
cancel: "a.ui-icon",
revert: true,
cursor: "move",
revertDuration: 0
});
}
$(this).addClass('has-drop').append($item);
}
});

jQuery UI sortable - do something on start and remove on drop

I have two block one is "draggable" and the other is "sortable".
When I start dragging an item from "sortable" I want to add a background color to a div and if I stop dragging it I want to remove the background color.
Here's my JS:
$(".sortableList").sortable({
start: function(event, ui) {
if (event.handleObj.namespace=="sortable")
$('.background').show();
},
update: function(event, ui) {
if (event.handleObj.namespace=="sortable")
$('.background').hide();
}
});
$(".draggable").draggable({
connectToSortable: '.sortableList',
cursor: 'pointer',
helper: 'clone',
revert: 'invalid',
start: function (event, ui) {
$(this).addClass('testing');
}
});
Here's a jsbin containing a live example of what I'm trying to do.
The problem is that when I start dragging an item from "sortable" and drop it in the same place it was the background color remains the same and I'm not expecting this.
How can I do this?
Use the stop event instead of the update event:
$(".sortableList").sortable({
start: function(event, ui) {
if (event.handleObj.namespace=="sortable")
$('.background').show();
},
stop: function(event, ui) {
if (event.handleObj.namespace=="sortable")
$('.background').hide();
}
});

JQuery: dropped divs are sortable only after second click

When I drop some divs into a sortable pane, I can grab the newly created divs only after the second time I click on them.
I suppose this is a refresh-related issue, but I cannot figure out how to make it work.
Here is the jsfiddle: http://jsfiddle.net/DvE5Q/
And the code:
$(".box").draggable({
helper: 'clone'
});
$("#left").droppable({
accept: '.box.out',
drop: function (e, ui) {
$(this).append('<div class="box"></div>');
var droppedBox = $(this).children().last();
$(droppedBox).html(ui.helper.html());
}
});
$("#left").sortable();
Thanks for your help!
I would use the attribute connectToSortable: '#left'
DEMO http://jsfiddle.net/DvE5Q/1/
$(".box").draggable({
helper: 'clone',
connectToSortable: '#left'
});
$("#left").droppable({
accept: '.box.out',
drop: function (e, ui) {
}
});
$("#left").sortable();

jQuery UI: Drag and clone from original div, but keep clones

I have a div, which has jQuery UI Draggable applied. What I want to do, is click and drag that, and create a clone that is kept in the dom and not removed when dropped.
Think of a deck of cards, my box element is the deck, and I want to pull cards/divs off that deck and have them laying around my page, but they would be clones of the original div. I just want to make sure that you cannot create another clone of one of the cloned divs.
I have used the following, which didn't work like I wanted:
$(".box").draggable({
axis: 'y',
containment: 'html',
start: function(event, ui) {
$(this).clone().appendTo('body');
}
});
I figured out my solution:
$(".box-clone").live('mouseover', function() {
$(this).draggable({
axis: 'y',
containment: 'html'
});
});
$(".box").draggable({
axis: 'y',
containment: 'html',
helper: 'clone'
stop: function(event, ui) {
$(ui.helper).clone(true).removeClass('box ui-draggable ui-draggable-dragging').addClass('box-clone').appendTo('body');
}
});
Here is what I finally did that worked:
$(".box-clone").live('mouseover', function() {
$(this).draggable({
axis: 'y',
containment: 'html'
});
});
$(".box").draggable({
axis: 'y',
containment: 'html',
helper: 'clone',
stop: function(event, ui) {
$(ui.helper).clone(true).removeClass('box ui-draggable ui-draggable-dragging').addClass('box-clone').appendTo('body');
}
});
If you're tring to move elements (say <li/>) from a #source <ul/> to a #destination <ul/>, and you'd like them to clone (as opposed to move), and still be sortable on the right, I found this solution:
$(function() {
$("#source li").draggable({
connectToSortable: '#destination',
helper: 'clone'
})
$("#destination").sortable();
});
I know it seems ultra simple, but it worked for me! :)
Here was his solution:
$(".box-clone").live('mouseover', function() {
$(this).draggable({
axis: 'y',
containment: 'html'
});
});
$(".box").draggable({
axis: 'y',
containment: 'html',
helper: 'clone'
stop: function(event, ui) {
$(ui.helper).clone(true).removeClass('box ui-draggable ui-draggable-dragging').addClass('box-clone').appendTo('body');
}
});
Here is how I got it working:
PS: 'marker' is the object to drag and 'map' is the destination container.
$(document).ready(function() {
//source flag whether the drag is on the marker tool template
var template = 0;
//variable index
var j = 0;
$(".marker").draggable({
helper: 'clone',
snap: '.map',
start: function(event, ui) {
//set the marker tool template
template = 1;
}
});
$(".map").droppable({
accept: ".marker",
drop: function(event, ui) {
$(this).find('.map').remove();
var item = $(ui.helper);
var objectid = item.attr('id');
//if the drag is on the marker tool template
if (template == 1) {
var cloned = $(item.clone());
cloned.attr('id', 'marker' + j++);
objectid = cloned.attr('id');
cloned.draggable({
containment: '.map',
cursor: 'move',
snap: '.map',
start: function(event, ui) {
//Reset the drag source flag
template = 0;
}
});
cloned.bind("contextmenu", function(e) {
cloned.remove();
return false;
});
$(this).append(cloned);
}
i++;
var offsetXPos = parseInt(ui.offset.left - $(this).offset().left);
var offsetYPos = parseInt(ui.offset.top - $(this).offset().top);
alert("Dragged " + objectid + " to (" + offsetXPos + "," + offsetYPos + ")");
}
});
});
