drag and drop element to any location? - javascript

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);
}

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

Drop element centered on mouse position

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:
https://jsfiddle.net/littletrives/6p8grnsk/143/
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',
});

Jquery - appending after re-registering

On this script I have drag and drop fieldsets (left menu - top). Drag multiple fieldsets into the right "working area". In those fieldsets is an area for dropping Fields (of which I have one, left menu - bottom). Drop "Field One" into any of the dropped Fieldset (under the line in the "Drop Fields Here" area) in the working area.
I want to then move that Field One from the Fieldset I dropped it into and into the other Fieldset in the working area. I have got the Field One draggable but I cannot get it to append to the new Fieldset.
I am not wanting to delete the Field and replace it with another clone from the left menu. I am new to jquery so my code may be a bit messy. Any help is greatly appreciated. Jsfiddle and code below.
I believe the code issue is between line 21-29...but I am not sure.

var clone = $(ui.draggable).clone()

There will be a lot of work to do here, yet you can get over this hurdle like so:
https://jsfiddle.net/Twisty/6trmrfoo/32/
Basically, you want to assign a new .droppable() to a specific element in the field set when it is added to the #drop-area. I would advise using a function as you will do this a multitude of times.
You can also make use of .data() to store a source value along with the draggable elements. I only did this for fields since that was the only pace it seemed like it was needed. You can updated this once it's dropped into a fieldset so that future drag-n-drop operations can be handled properly, we don't want to clone the object we move it.
To move it, consider using .detach(). It'll detach the element from the current parent and can be used in chain to append or move into memory as a variable. Similar to .clone() just we're manipulating the actual object. .clone() is to "Copy & Paste" as .detach() is to "Cut & Paste".
JavaScript
$(function() {
var fs_count = 0;
function makeFieldTarget($fs) {
$fs.droppable({
accept: '.draggableField, .activeField',
drop: function(event, ui) {
var clone, cloneClass;
if (ui.draggable.data("source") == "sidebar") {
clone = $(ui.draggable).clone();
clone.removeClass('draggableField').addClass('activeField');
$(this).append(clone);
cloneClass = clone.attr('class');
console.log('DROPFIELD - you dropped a field from the side bar: ' + cloneClass);
clone.data("source", "fieldset").draggable({
zIndex: 1000
});
}
if (ui.draggable.data("source") == "fieldset") {
clone = ui.draggable;
clone.detach().attr("style", "").appendTo($(this));
cloneClass = clone.attr('class');
console.log('DROPFIELD - you dropped a field from a Field set: ' + cloneClass);
}
}
});
}
$("#drop-area").droppable({
accept: '.ui-draggable:not(.draggableField, .activeField)',
drop: function(event, ui) {
fs_count++;
var clone = $(ui.draggable).clone()
clone.addClass('connectedSortable');
if (clone.hasClass('dropped')) {
return false;
}
clone.addClass('connectedSortable dropped').attr('id', 'fs_' + fs_count);
$(this).append(clone);
var fs_class = clone.attr('class');
console.log('DROPAREA - You added a field with class ' + fs_class);
makeFieldTarget(clone.find(".fieldDroppable"));
$("#drop-area").sortable("refresh");
}
});

Alerting Order of Dropped Elements WITHOUT using jQuery sortable

https://jsfiddle.net/ianderso222/y9ynouxs/36/
I hope this makes sense, If I need to elaborate I will do so.
Right now the code is working pretty well, doing everything I need it to except this one issue. I just need to alert the order that the squares have been dropped in, after all 4 have been placed.
So, if square4 is placed in the large container, that would show up first in the alert. If square2 is in the last, smallest box it would be last in the list, and so on.
I would use sortable but I am afraid it would not work with the current setup. The resizing to different sized containers would not work, or at least I was not able to get it to work. If there is a way to keep the current structure of resizing to fill container and sliding into place I would say do that, but from everything I have seen I feel I would have to essentially start from scratch.
Here is the JavaScript, pardon the messy code:
$('.holderList li').droppable({
drop: function(event, ui) {
var droppable = $(this);
var draggable = ui.draggable;
console.log(draggable.attr('id') + ' is ' + droppable.attr('id'));
var $this = $(this);
ui.draggable.position({
my: "center",
at: "center",
of: $this,
using: function(pos) {
$(this).animate(pos, 200, "linear");
}
});
ui.draggable.addClass('dropped');
ui.draggable.data('droppedin', $(this));
$(this).droppable('disable');
setTimeout(function() {
var dragID = ui.draggable;
if (!$(".ui-droppable").not(".ui-droppable-disabled").length) {
alert(draggable.attr('id'));
}
}, 400);
},
});
$(".square").draggable({
stack: ".square",
revert: function(event, ui) {
//overwrite original position
$(this).data("ui-draggable").originalPosition = {
width: 50,
height: 50
}
//return boolean
return !event;
},
drag: function(event, ui) {
var draggable = $(this).data("ui-draggable");
$.each(draggable.snapElements, function(index, element) {
ui = $.extend({}, ui, {
snapElement: $(element.item),
snapping: element.snapping
});
if (element.snapping) {
if (!element.snappingKnown) {
element.snappingKnown = true;
draggable._trigger("snapped", event, ui);
}
} else if (element.snappingKnown) {
element.snappingKnown = false;
draggable._trigger("snapped", event, ui);
}
});
if ($(this).data('droppedin')) {
$(this).data('droppedin').droppable('enable');
$(this).data('droppedin', null)
$(this).removeClass('dropped')
}
},
snap: ".holder",
snapMode: "inner",
snapTolerance: 8,
snapped: function(event, ui) {
var squareWidth = ui.snapElement.width();
var squareHeight = ui.snapElement.height();
ui.helper.css({
width: squareWidth,
height: squareHeight
});
}
});
Take a look at my solution:
Demo
First it assigns a data-current attribute to the droppable holder on every drop and sets it to the id of the draggable.
Then it itterates trough all the .holder elements and prints their data-current
Simple but works.
// On single drop
drop: function(event,ui){
...
droppable.attr('data-current', draggable.attr('id') );
}
//On all dropped
$('.holder').each(function(el){
console.log($(this).attr('data-current'));
});

only allow one object to be dropped jquery

$("li").draggable({
helper: "clone"
});
$("#div1").droppable({
drop: function (event, ui) {
$("<p></p>").appendTo("#div1");
}
});
I have objects in a list that can be dragged and dropped into a div named div1. But when I drop one into the div i don't want to be able to drop another into it. I have tried using, for, if and while loops with a count.
Here is a full solution, it allows only one item dropped, but also, if one exists, it gets replaced on the next drop with the new one. (Usefull if someone changes their mind. Just call
refreshDragDrop(dragClassName,dropDivId);
refreshDragDrop = function(dragClassName,dropDivId) {
$( "." + dragClassName ).draggable({
connectToSortable: "#" + dropDivId,
helper: "clone",
revert: "invalid"
});
$("#" + dropDivId).droppable({
accept: '.' + dragClassName,
drop: function (event, ui) {
var $this = $(this),
maxItemsCount = 1;
if ($this.children('div').length == maxItemsCount ){
//more than one item,just replace
$(this).html($(ui.draggable).clone());
} else {
$(this).append($(ui.draggable).clone());
}
}
});
}
This should help:
drop: function (event, ui) {
var $this = $(this),
maxItemsCount = 1;
if ($this.children('li').length > maxItemsCount ){
ui.sender.draggable('cancel');
alert("To much items!");
}
}

Show hidden button on droppable :: javascript

Even if only one icon from my draggable box is dropped into the droppable area, I would like a hidden button to appear.
I am unsure if I could reference the css class I used to hide it or have the JavaScript generate the button.
This button will be needed later for an onClick event for a modal box.
Any help would be appreciated. :)
jsfiddle to look at http://jsfiddle.net/JeLZr/4/
The code below is what I am having issues with.
if ($(this).find('.draggable').length === 0) {
$(this).append($(ui.draggable));
if($(ui.draggable).find('button.generateReport').length === 0){
$(ui.draggable).append('<input type="button" id="generateReport" class="BtnReport" />');
}
}
[edit] I realize this is a lot of to ask but is there any chance anyone can help with; as well as dragging the icon, if it is double clicked it will move into the droppable box?? Is this even possible with draggable/droppable??
An attempt to answer the first question:
$("#drop").droppable({
accept: ".draggable",
drop: function (event, ui) {
$('.BtnReport').show();
console.log("drop");
$(this).addClass("over");
var dropped = ui.draggable;
var droppedOn = $(this);
$(dropped).detach().css({
top: 0,
left: 0
}).appendTo(droppedOn);
},
over: function (event, elem) {
$(this).addClass("over");
console.log("over");
},
out: function (event, elem) {
$(this).removeClass("over");
}
});
$("#drop").sortable();
$("#grid").droppable({
accept: ".draggable",
drop: function (event, ui) {
if($('#drop img').length == 1)
$('.BtnReport').hide();
console.log("drop");
$(this).removeClass("over");
var dropped = ui.draggable;
var droppedOn = $(this);
$(dropped).detach().css({
top: 0,
left: 0
}).appendTo(droppedOn);
http://jsfiddle.net/trevordowdle/JeLZr/5/
I can look into the second question as well but it might be best to Create another question for it.
