The draggables in my drag and drop game should only be able to be dropped in the designated area highlighted by the css.
$('.drag').draggable({
helper: 'clone',
snap: '.drop',
grid: [60, 60],
revert: 'invalid'
});
$('.drop').droppable ({
drop: function(event, ui) {
word = $(this).data('word');
}
});
The CSS style is called .showword, and the click event that triggers it is called "#picknext".
Any ideas how I would get the draggable to revert if it wasn't dropped in the styled area?
Something like this...
$('#picknext').click({
drop: function(event, ui) {
word = $(this).data('word');
}
});
Here is something that should get you started.

Rather than having a function for your revert property you want to set it to invalid as discussed in that options help: http://docs.jquery.com/UI/Draggable#option-revert

I'm new to jquery, there is no question on this, I wanted my submit button able to get ids of multiple images in droppable, anyone can help? please help me or guide me along... I need to get the ids of the image that is only dragged inside the droppable and when submit button is pressed.. Display the image that is only inside droppable..
jsFiddle
https://jsfiddle.net/xInfinityMing/azvvhxvL/
JavaScript
$(function() {
$("#dragIcons img").draggable({
revert: "invalid",
refreshPositions: true,
cursor: "move",
cursorAt: {
top: 56,
left: 56
},
drag: function(event, ui) {
ui.helper.removeClass("end-draggable");
ui.helper.addClass("draggable");
},
stop: function(event, ui) {
ui.helper.addClass("end-draggable");
ui.helper.removeClass("draggable");
}
});
$("#briefcase-full").droppable({
greedy: true,
tolerance: 'touch',
drop: function(event, ui) {
var id = ui.draggable.attr("id");
alert(id);
if ($("#briefcase").length == 0) {
$("#briefcase-droppable").html("");
}
ui.draggable.addClass("dropped");
$("#briefcase-droppable").append(ui.draggable);
}
});
});
Basically, all the dragged element will go inside the droppable. so you can use children to check every elements.
$("#briefcase-droppable").children(".icons").each(function() {
var icon_id= $(this).attr("id");
});

I suggest you to use class instead of using img element to attach draggable event.
I have a droppable unordered list named <ul class="droppable">. Inside the unordered list I have dynamicly generated list items named <li class="placeholder"></li>, which are also droppable.
When dropping a draggable item between a placeholder, all works fine. But when dropping a draggable item on the <li class="placeholder"></li> itself, the draggable item gets appended to the placeholder and the unordered list.
So I get a double clone of it.
Here's a jsfiddle to have a visual example. I'm aware that it is logical that I get a double clone on my page, but I don't know how to disable it...
Any help is greatly appreciated!
UPDATE: If you drag a draggable item verticaly over a droppable element, they append automatically? How is that possible?
One approach you could try to solve this would be to move all your behaviors to your sortable and use droppable only to make a switch to determine the behavior you need. That way, you can handle everything at one place, which should resolve some of the unwanted effects of having both sortable and droppable on the same elements. Like this:
In your droppable you set the switch on over and out, and set the objects you need.
$("li.placeholder").droppable({
accept: "li.to-drag",
hoverClass: "correct",
activeClass: "active",
revert: false,
tolerance: "pointer",
over: function (e, ui) {
curDrag = ui.draggable;
curTarget = e.target;
curThis = $(this);
overSortable = true;
},
out: function (e, ui) {
overSortable = false;
},
drop: function (event, ui) {
}
});
Then, in beforeStop event of sortable, you check if the variable overSortable is true or not and set the behaviors there. All that refers to ui.draggable, this, and event.target will need to be replaced by the objects you set in droppable. An event better way would be to make a function handling all these behaviors and pass these as arguments.
beforeStop: function (e, ui) {
if (overSortable) {
curDrag.addClass('placeholder');
var dragging = curDrag.find("img").remove();
curThis.append(dragging).addClass("dropped");
curThis.droppable('disable');
var day = curDrag.attr('data-id');
var index = $(curTarget).index();
//...
} else {
ui.item.addClass('placeholder')
}
There are still adjusments to make, it's not completely clear what exactly should happen and when, but this can make it easier to work instead of trying to manage multiple events being fired when you drop an element, you only manage one.
http://jsfiddle.net/ts290vth/4/
Managed to get it working for you:
function dropping () {
$("li.placeholder").droppable({
accept: "li.to-drag",
hoverClass: "correct",
activeClass: "active",
revert: false,
tolerance: "pointer",
drop: function (event, ui) {
var dragging = ui.draggable.find("img");
$(this).append(dragging).addClass("dropped");
$(this).droppable('disable');
var day = $(ui.draggable).attr('data-id');
var index = $(event.target).index();
$(this).attr("data-id", day);
$(this).attr("date-order", index);
$(this).addClass("drop-"+ index);
$(this).attr("data-content", "");
NOTICE: the var dragging = ui.draggable.find("img"); this line was making you duplicated copies at drag and drop so you just had to remove the clone();.
it created clones of your dragged items at dest.
Now Notice this:
$("#dropzone").droppable({
accept: "li.to-drag",
revert: false,
tolerance: "pointer",
drop: function (event, ui) {
$(this).append(dragging);
//$("li.to-drag").addClass("placeholder");
$(this).droppable('disable');
}
});
}
Something with the placeholder class is causing you troubles.
Hope this helps.
Hi I wan that an event starts wenn droppable element snapps in?
is there any possibility to realise this?
Js looks like this at the moment:
function MatchingTask(questions, answers) {
// Elemente Drag n Drop faehig machen
$(".match_task_draggable").draggable({
cursor: 'move',
containment: $('.match_task_draggable').parent('div').parent('div'),
scroll: false,
snap: ".match_task_drop",
snapMode: "inner",
stop: setDroppableAnswer
});
}
// Set Answer
function setDroppableAnswer(){
alert("Ba");
}
But stop reacts every time I drop an element, it should only react when it is dropped to the snap area
Solution:
$(".match_task_drop").droppable({
drop: function( event, ui ) {
setDroppableAnswer( ui.draggable );
}
});
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();
}
});
Basically what I have is a set of doodads, and what I need to do is to be able to drag any item in that set into a containment box. Once they are in the box, they can still be moved around and manipulated freely, but they can't be taken out of the box again though they can be deleted.
The doodads are also set to clone as a user can have more than one of the item in the box if they so desire.
So the two parts are, set up the doodad list (already done), and then make it draggable so that it can be dragged into the droppable div box. Then the second part is that once it's in the div box, it must be draggable again, not clonable, and also contained in the box.
Here's my JS code:
$(document).ready(function() {
function MakeDraggable(item) {
item.draggable({
revert : "invalid"
});
}
$(".doodad").draggable({
helper : 'clone',
scroll : true
});
$(".dropped").draggable ({
containment: ".box"
});
$(".box").droppable({
accept : ".doodad",
activeClass : "ui-state-default",
hoverClass : "ui-state-hover",
drop : function(event, ui) {
var droppedItem = $(ui.draggable).clone();
//droppedItem.class = ".dropped";
droppedItem.draggable();
//ui.draggable.draggable('option', 'revert', false);
//droppedItem.draggable();
$(this).append(droppedItem);
}
});
});
I've tried many things. I tried changing the element's ID to something else so that it can take on that class' draggable attributes. I've also tried programming it within the drop function, but I'm having issues.
I have no idea how to refer to the draggable element just dropped in order to manipulate it. I was told it was $(ui.draggable), or $(ui.draggable).clone(), but when I try referring to that and calling draggable on it with my desired options, it doesn't work. The best I've gotten was that it was draggable after dropping, but it kept duplicating itself and was not contained within the box.
Any help would be greatly appreciated, and I am new to all of this stuff. I did look at the JQuery API but it didn't help me much in this regard.
Edit:
My Html is:
<body>
<img src="doodads/i1.gif" class="doodad">
<img src="doodads/i2.gif" class="doodad">
<img src="doodads/i3.gif" class="doodad">
<img src="doodads/i4.gif" class="doodad">
<div class="box" />
</body>
CSS is:
.box {
width:500px;
height:500px;
background: orange;
}
You can set a class on the dropped element e.g. copied and than check if the dropped element have already that class and if so stop the cloning.
To constrain the movement inside the box you can use containment option of draggable:
Constrains dragging to within the bounds of the specified element or
region.
Code:
$(document).ready(function () {
$(".doodad").draggable({
helper: 'clone',
scroll: true
});
$(".dropped").draggable({
containment: ".box"
});
$(".box").droppable({
accept: ".doodad",
activeClass: "ui-state-default",
hoverClass: "ui-state-hover",
drop: function (event, ui) {
if ($(ui.draggable).hasClass('copied')) return
var droppedItem = $(ui.draggable).clone().addClass('copied');
droppedItem.draggable({
containment: ".box"
});
$(this).append(droppedItem);
}
});
});
Demo: http://jsfiddle.net/IrvinDominin/ufHMm/
EDIT
To get the dropped element position we had to calculate and use it, using:
$(ui.helper).position().top - $(this).position().top
$(ui.helper).position().left - $(this).position().left
we get the helper position along its container.
Final code:
$(document).ready(function () {
$(".doodad").draggable({
helper: 'clone',
scroll: true
});
$(".dropped").draggable({
containment: ".box"
});
$(".box").droppable({
accept: ".doodad",
activeClass: "ui-state-default",
hoverClass: "ui-state-hover",
drop: function (e, ui) {
if ($(ui.draggable).hasClass('copied')) return
var droppedItem = $(ui.draggable).clone().addClass('copied').css({
position: "relative",
top: $(ui.helper).position().top - $(this).position().top,
left: $(ui.helper).position().left - $(this).position().left
}).draggable({
containment: ".box"
});
$(this).append(droppedItem);
}
});
});
