The problem I'm having is that the dragleave
event of an element is fired when hovering a child element of that element. Also, dragenter
is not fired when hovering back the parent element again.
I made a simplified fiddle: http://jsfiddle.net/pimvdb/HU6Mk/1/.
HTML:
<div id="drag" draggable="true">drag me</div>
<hr>
<div id="drop">
drop here
<p>child</p>
parent
</div>
with the following JavaScript:
$('#drop').bind({
dragenter: function() {
$(this).addClass('red');
},
dragleave: function() {
$(this).removeClass('red');
}
});
$('#drag').bind({
dragstart: function(e) {
e.allowedEffect = "copy";
e.setData("text/plain", "test");
}
});
What it is supposed to do is notifying the user by making the drop div
red when dragging something there. This works, but if you drag into the p
child, the dragleave
is fired and the div
isn't red anymore. Moving back to the drop div
also doesn't make it red again. It's necessary to move completely out of the drop div
and drag back into it again to make it red.
Is it possible to prevent dragleave
from firing when dragging into a child element?
2017 Update: TL;DR, Look up CSS pointer-events: none;
as described in @H.D.'s answer below that works in modern browsers and IE11.
dragleave
is still fired in that case.
You just need to keep a reference counter, increment it when you get a dragenter, decrement when you get a dragleave. When the counter is at 0 - remove the class.
var counter = 0;
$('#drop').bind({
dragenter: function(ev) {
ev.preventDefault(); // needed for IE
counter++;
$(this).addClass('red');
},
dragleave: function() {
counter--;
if (counter === 0) {
$(this).removeClass('red');
}
}
});
Note: In the drop event, reset counter to zero, and clear the added class.

Is it possible to prevent dragleave from firing when dragging into a child element?
Yes.
#drop * {pointer-events: none;}
That CSS seem to be enough for Chrome.
While using it with Firefox, the #drop shouldn't have text nodes directly (else there's a strange issue where a element "leave it to itself"), so I suggest to leave it with only one element (e.g., use a div inside #drop to put everything inside)
Here's a jsfiddle solving the original question (broken) example.
I've also made a simplified version forked from the @Theodore Brown example, but based only in this CSS.
Not all browsers have this CSS implemented, though: http://caniuse.com/pointer-events
Seeing the Facebook source code I could find this pointer-events: none;
several times, however it's probably used together with graceful degradation fallbacks. At least it's so simple and solves the problem for a lot of environments.
pointer-events: none;
to a class. Apply the class to the drop target, using ondragenter. Then remove the class from the drop target in ondragleave.
It has been quite some time after this question is asked and a lot of solutions (including ugly hacks) are provided.
I managed to fix the same problem I had recently thanks to the answer in this answer and thought it may be helpful to someone who comes through to this page. The whole idea is to store the evenet.target
in ondrageenter
everytime it is called on any of the parent or child elements. Then in ondragleave
check if the current target (event.target
) is equal to the object you stored in ondragenter
.
The only case these two are matched is when your drag is leaving the browser window.
The reason that this works fine is when the mouse leaves an element (say el1
) and enters another element (say el2
), first the el2.ondragenter
is called and then el1.ondragleave
. Only when the drag is leaving/entering the browser window, event.target
will be ''
in both el2.ondragenter
and el1.ondragleave
.
Here is my working sample. I have tested it on IE9+, Chrome, Firefox and Safari.
(function() {
var bodyEl = document.body;
var flupDiv = document.getElementById('file-drop-area');
flupDiv.onclick = function(event){
console.log('HEy! some one clicked me!');
};
var enterTarget = null;
document.ondragenter = function(event) {
console.log('on drag enter: ' + event.target.id);
enterTarget = event.target;
event.stopPropagation();
event.preventDefault();
flupDiv.className = 'flup-drag-on-top';
return false;
};
document.ondragleave = function(event) {
console.log('on drag leave: currentTarget: ' + event.target.id + ', old target: ' + enterTarget.id);
//Only if the two target are equal it means the drag has left the window
if (enterTarget == event.target){
event.stopPropagation();
event.preventDefault();
flupDiv.className = 'flup-no-drag';
}
};
document.ondrop = function(event) {
console.log('on drop: ' + event.target.id);
event.stopPropagation();
event.preventDefault();
flupDiv.className = 'flup-no-drag';
return false;
};
})();
And here is a simple html page:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Multiple File Uploader</title>
<link rel="stylesheet" href="my.css" />
</head>
<body id="bodyDiv">
<div id="cntnr" class="flup-container">
<div id="file-drop-area" class="flup-no-drag">blah blah</div>
</div>
<script src="my.js"></script>
</body>
</html>
With proper styling what I have done is to make the inner div (#file-drop-area) much bigger whenever a file is dragged into the screen so that the user can easily drop the files into the proper place.
==
over ===
. You are comparing the event target object references, so ===
works fine too.
onDragEnter
and check against in onDragLeave
. This should be the accepted answer.
Here, the simplest Cross-Browser solution (seriously):
jsfiddle <-- try dragging some file inside the box
You can do something like that:
var dropZone= document.getElementById('box');
var dropMask = document.getElementById('drop-mask');
dropZone.addEventListener('dragover', drag_over, false);
dropMask.addEventListener('dragleave', drag_leave, false);
dropMask.addEventListener('drop', drag_drop, false);
In a few words, you create a "mask" inside the dropzone, with width & height inherited, position absolute, that will just show when the dragover starts. So, after showing that mask, you can do the trick by attaching the others dragleave & drop events on it.
After leaving or dropping, you just hide the mask again. Simple and without complications.
(Obs.: Greg Pettit advice -- You must be sure that the mask hover the entire box, including the border)
#drop::before
or ::after
. Also, beware that sometimes, when dragging fast, the "dragleave" fires before the "dragenter" has finished. If the dragenter add the class/pseudoelement, and the dragleave removes then, this can cause problem.
The "right" way to solve this issue is to disable pointer events on child elements of the drop target (as in @H.D.'s answer). Here's a jsFiddle I created which demonstrates this technique. Unfortunately, this doesn't work in versions of Internet Explorer prior to IE11, since they didn't support pointer events.
Luckily, I was able to come up with a workaround which does work in old versions of IE. Basically, it involves identifying and ignoring dragleave
events which occur when dragging over child elements. Because the dragenter
event is fired on child nodes before the dragleave
event on the parent, separate event listeners can be added to each child node which add or remove an "ignore-drag-leave" class from the drop target. Then the drop target's dragleave
event listener can simply ignore calls which occur when this class exists. Here's a jsFiddle demonstrating this workaround. It is tested and working in Chrome, Firefox, and IE8+.
Update:
I created a jsFiddle demonstrating a combined solution using feature detection, where pointer events are used if supported (currently Chrome, Firefox, and IE11), and the browser falls back to adding events to child nodes if pointer event support isn't available (IE8-10).
dragleave
event from firing in Chrome, Firefox, and IE11+. I also updated my other workaround to support IE8 and IE9, in addition to IE10. It is intentional that the dropzone effect is only added when dragging the "Drag me" link. Others can feel free to change this behavior as needed to support their use cases.
This fairly simple solution is working for me so far, assuming your event is attached to each drag element individually.
if (evt.currentTarget.contains(evt.relatedTarget)) {
return;
}
if you are using HTML5, you can get the parent's clientRect:
let rect = document.getElementById("drag").getBoundingClientRect();
Then in the parent.dragleave():
dragleave(e) {
if(e.clientY < rect.top || e.clientY >= rect.bottom || e.clientX < rect.left || e.clientX >= rect.right) {
//real leave
}
}
border-radius
, moving the pointer close to the corner would actually leave the element, but this code would still think we are inside (we have left the element but we are still in the bounding rectangle). Then the dragleave
event handler won't be called at all.
A very simple solution is to use the pointer-events
CSS property. Just set its value to none
upon dragstart on every child element. These elements won't trigger mouse-related events anymore, so they won't catch the mouse over them and thus won't trigger the dragleave on the parent.
Don't forget to set this property back to auto
when finishing the drag ;)
A simple solution is to add the css rule pointer-events: none
to the child component to prevent the trigger of ondragleave
. See example:
function enter(event) {
document.querySelector('div').style.border = '1px dashed blue';
}
function leave(event) {
document.querySelector('div').style.border = '';
} div {
border: 1px dashed silver;
padding: 16px;
margin: 8px;
}
article {
border: 1px solid silver;
padding: 8px;
margin: 8px;
}
p {
pointer-events: none;
background: whitesmoke;
}
child not triggering dragleave
dragged = event.target;clone = dragged.cloneNode();clone.style.pointerEvents = 'none';
.no-pointer-events {pointer-events: none;}
then add no-pointer-events
to each child element. Done.
The problem is that the dragleave
event is being fired when the mouse goes in front of the child element.
I've tried various methods of checking to see if the e.target
element is the same as the this
element, but couldn't get any improvement.
The way I fixed this problem was a bit of a hack, but works 100%.
dragleave: function(e) {
// Get the location on screen of the element.
var rect = this.getBoundingClientRect();
// Check the mouseEvent coordinates are outside of the rectangle
if(e.x > rect.left + rect.width || e.x < rect.left
|| e.y > rect.top + rect.height || e.y < rect.top) {
$(this).removeClass('red');
}
}
if (e.x >= (rect.left + rect.width) || e.x <= rect.left || e.y >= (rect.top + rect.height) || e.y <= rect.top)
e.x
and e.y
.
Very simple solution:
parent.addEventListener('dragleave', function(evt) {
if (!parent.contains(evt.relatedTarget)) {
// Here it is only dragleave on the parent
}
}
You can fix it in Firefox with a little inspiration from the jQuery source code:
dragleave: function(e) {
var related = e.relatedTarget,
inside = false;
if (related !== this) {
if (related) {
inside = jQuery.contains(this, related);
}
if (!inside) {
$(this).removeClass('red');
}
}
}
Unfortunately it doesn't work in Chrome because relatedTarget
appears not to exist on dragleave
events, and I assume you're working in Chrome because your example did't work in Firefox. Here's a version with the above code implemented.
And here it goes, a solution for Chrome:
.bind('dragleave', function(event) {
var rect = this.getBoundingClientRect();
var getXY = function getCursorPosition(event) {
var x, y;
if (typeof event.clientX === 'undefined') {
// try touch screen
x = event.pageX + document.documentElement.scrollLeft;
y = event.pageY + document.documentElement.scrollTop;
} else {
x = event.clientX + document.body.scrollLeft + document.documentElement.scrollLeft;
y = event.clientY + document.body.scrollTop + document.documentElement.scrollTop;
}
return { x: x, y : y };
};
var e = getXY(event.originalEvent);
// Check the mouseEvent coordinates are outside of the rectangle
if (e.x > rect.left + rect.width - 1 || e.x < rect.left || e.y > rect.top + rect.height - 1 || e.y < rect.top) {
console.log('Drag is really out of area!');
}
})
border-radius
as I explained in my comment on @azlar's answer above.
I was having the same issue and tried to use pk7s solution. It worked but it could be done a little bit better without any extra dom elements.
Basicly the idea is same - add an extra unvisible overlay over droppable area. Only lets do this without any extra dom elements. Here is the part were CSS pseudo-elements come to play.
Javascript
var dragOver = function (e) {
e.preventDefault();
this.classList.add('overlay');
};
var dragLeave = function (e) {
this.classList.remove('overlay');
};
var dragDrop = function (e) {
this.classList.remove('overlay');
window.alert('Dropped');
};
var dropArea = document.getElementById('box');
dropArea.addEventListener('dragover', dragOver, false);
dropArea.addEventListener('dragleave', dragLeave, false);
dropArea.addEventListener('drop', dragDrop, false);
CSS
This after rule will create a fully covered overlay for droppable area.
#box.overlay:after {
content:'';
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
z-index: 1;
}
Here is the full solution: http://jsfiddle.net/F6GDq/8/
I hope it helps anyone with the same problem.
Here's another solution using document.elementFromPoint:
dragleave: function(event) {
var event = event.originalEvent || event;
var newElement = document.elementFromPoint(event.pageX, event.pageY);
if (!this.contains(newElement)) {
$(this).removeClass('red');
}
}
Hope this works, here's a fiddle.
event.clientX, event.clientY
instead, since they're relative to the viewport and not the page. I hope that helps another lost soul out there.
Not sure if this cross browser, but I tested in Chrome and it solves my problem:
I want to drag and drop a file over entire page, but my dragleave is fired when i drag over child element. My fix was to look at the x and y of mouse:
i have a div that overlays my entire page, when the page loads i hide it.
when you drag over document i show it, and when you drop on the parent it handles it, and when you leave the parent i check x and y.
$('#draganddrop-wrapper').hide();
$(document).bind('dragenter', function(event) {
$('#draganddrop-wrapper').fadeIn(500);
return false;
});
$("#draganddrop-wrapper").bind('dragover', function(event) {
return false;
}).bind('dragleave', function(event) {
if( window.event.pageX == 0 || window.event.pageY == 0 ) {
$(this).fadeOut(500);
return false;
}
}).bind('drop', function(event) {
handleDrop(event);
$(this).fadeOut(500);
return false;
});
I've stumbled into the same problem and here's my solution - which I think is much easier then above. I'm not sure if it's crossbrowser (might depend on even bubbling order)
I'll use jQuery for simplicity, but solution should be framework independent.
The event bubbles to parent either way so given:
<div class="parent">Parent <span>Child</span></div>
We attach events
el = $('.parent')
setHover = function(){ el.addClass('hovered') }
onEnter = function(){ setTimeout(setHover, 1) }
onLeave = function(){ el.removeClass('hovered') }
$('.parent').bind('dragenter', onEnter).bind('dragleave', onLeave)
And that's about it. :) it works because even though onEnter on child fires before onLeave on parent, we delay it slightly reversing the order, so class is removed first then reaplied after a milisecond.
An alternate working solution, a little simpler.
//Note: Due to a bug with Chrome the 'dragleave' event is fired when hovering the dropzone, then
// we must check the mouse coordinates to be sure that the event was fired only when
// leaving the window.
//Facts:
// - [Firefox/IE] e.originalEvent.clientX < 0 when the mouse is outside the window
// - [Firefox/IE] e.originalEvent.clientY < 0 when the mouse is outside the window
// - [Chrome/Opera] e.originalEvent.clientX == 0 when the mouse is outside the window
// - [Chrome/Opera] e.originalEvent.clientY == 0 when the mouse is outside the window
// - [Opera(12.14)] e.originalEvent.clientX and e.originalEvent.clientY never get
// zeroed if the mouse leaves the windows too quickly.
if (e.originalEvent.clientX <= 0 || e.originalEvent.clientY <= 0) {
clientX
above 0 when the mouse is outside of the box. Granted, my elements are position:absolute
console.log(e.clientX + "/" + e.clientY ); if (e.clientX == 0 && e.clientY == 0 ) { console.log('REAL leave'); }
I've written a little library called Dragster to handle this exact issue, works everywhere except silently doing nothing in IE (which doesn't support DOM Event Constructors, but it'd be pretty easy to write something similar using jQuery's custom events)
Just check if the dragged over element is a child, if it is, then don't remove your 'dragover' style class. Pretty simple and works for me:
$yourElement.on('dragleave dragend drop', function(e) {
if(!$yourElement.has(e.target).length){
$yourElement.removeClass('is-dragover');
}
})
I wrote a drag-and-drop module called drip-drop that fixes this weirdo behavior, among others. If you're looking for a good low-level drag-and-drop module you can use as the basis for anything (file upload, in-app drag-and-drop, dragging from or to external sources), you should check this module out:
https://github.com/fresheneesz/drip-drop
This is how you would do what you're trying to do in drip-drop:
$('#drop').each(function(node) {
dripDrop.drop(node, {
enter: function() {
$(node).addClass('red')
},
leave: function() {
$(node).removeClass('red')
}
})
})
$('#drag').each(function(node) {
dripDrop.drag(node, {
start: function(setData) {
setData("text", "test") // if you're gonna do text, just do 'text' so its compatible with IE's awful and restrictive API
return "copy"
},
leave: function() {
$(node).removeClass('red')
}
})
})
To do this without a library, the counter technique is what I used in drip-drop, tho the highest rated answer misses important steps that will cause things to break for everything except the first drop. Here's how to do it properly:
var counter = 0;
$('#drop').bind({
dragenter: function(ev) {
ev.preventDefault()
counter++
if(counter === 1) {
$(this).addClass('red')
}
},
dragleave: function() {
counter--
if (counter === 0) {
$(this).removeClass('red');
}
},
drop: function() {
counter = 0 // reset because a dragleave won't happen in this case
}
});
I found a simple solution to this problem so sharing it. It works well in my case.
jsfiddle try it.
You can actually achieve this only via the dragenter
event and you don't even need to register a dragleave
. All you need is to have a no-drop area around your dropzones and that's it.
You can also have nested dropzones and this works perfectly. Check this as well nested dropzones.
$('.dropzone').on("dragenter", function(e) {
e.preventDefault();
e.stopPropagation();
$(this).addClass("over");
$(".over").not(this).removeClass("over"); // in case of multiple dropzones
});
$('.dropzone-leave').on("dragenter", function(e) {
e.preventDefault();
e.stopPropagation();
$(".over").removeClass("over");
});
// UPDATE
// As mar10 pointed out, the "Esc" key needs to be managed,
// the easiest approach is to detect the key and clean things up.
$(document).on('keyup', function(e){
if (e.key === "Escape") {
$(".over").removeClass("over");
}
});
dragend
event to handle this, but i will need to test that.
dragend
event is triggered by releasing a mouse button or pressing the Esc key, so going with the dragend
event will complicate the logic, so the simple solution is to detect the Escape key as you said. I've updated the answer.
After spending so many hours I got that suggestion working exactly as intended. I wanted to provide a cue only when files were dragged over, and document dragover, dragleave was causing painful flickers on Chrome browser.
This is how I solved it, also throwing in proper cues for user.
$(document).on('dragstart dragenter dragover', function(event) {
// Only file drag-n-drops allowed, http://jsfiddle.net/guYWx/16/
if ($.inArray('Files', event.originalEvent.dataTransfer.types) > -1) {
// Needed to allow effectAllowed, dropEffect to take effect
event.stopPropagation();
// Needed to allow effectAllowed, dropEffect to take effect
event.preventDefault();
$('.dropzone').addClass('dropzone-hilight').show(); // Hilight the drop zone
dropZoneVisible= true;
// http://www.html5rocks.com/en/tutorials/dnd/basics/
// http://api.jquery.com/category/events/event-object/
event.originalEvent.dataTransfer.effectAllowed= 'none';
event.originalEvent.dataTransfer.dropEffect= 'none';
// .dropzone .message
if($(event.target).hasClass('dropzone') || $(event.target).hasClass('message')) {
event.originalEvent.dataTransfer.effectAllowed= 'copyMove';
event.originalEvent.dataTransfer.dropEffect= 'move';
}
}
}).on('drop dragleave dragend', function (event) {
dropZoneVisible= false;
clearTimeout(dropZoneTimer);
dropZoneTimer= setTimeout( function(){
if( !dropZoneVisible ) {
$('.dropzone').hide().removeClass('dropzone-hilight');
}
}, dropZoneHideDelay); // dropZoneHideDelay= 70, but anything above 50 is better
});
"dragleave" event is fired when mouse pointer exits the dragging area of the target container.
Which makes a lot of sense as in many cases only the parent may be droppable and not the descendants. I think event.stopPropogation() should have handled this case but seems like it doesn't do the trick.
Above mentioned some solutions do seem to work for most of the cases, but fails in case of those children which does not support dragenter / dragleave events, such as iframe.
1 workaround is to check the event.relatedTarget and verify if it resides inside the container then ignore the dragleave event as I have done here:
function isAncestor(node, target) {
if (node === target) return false;
while(node.parentNode) {
if (node.parentNode === target)
return true;
node=node.parentNode;
}
return false;
}
var container = document.getElementById("dropbox");
container.addEventListener("dragenter", function() {
container.classList.add("dragging");
});
container.addEventListener("dragleave", function(e) {
if (!isAncestor(e.relatedTarget, container))
container.classList.remove("dragging");
});
You can find a working fiddle here!
I know this is a old question but wanted to add my preference. I deal with this by adding class triggered css :after element at a higher z-index then your content. This will filter out all the garbage.
.droppable{
position: relative;
z-index: 500;
}
.droppable.drag-over:after{
content: "";
display:block;
position:absolute;
left:0;
right:0;
top:0;
bottom:0;
z-index: 600;
}
Then just add the drag-over class on your first dragenter event and none of the child elements trigger the event any longer.
dragEnter(event){
dropElement.classList.add('drag-over');
}
dragLeave(event){
dropElement.classList.remove('drag-over');
}
I had a similar problem — my code for hiding the dropzone on dragleave event for body was fired contatantly when hovering child elements making the dropzone flicker in Google Chrome.
I was able to solve this by scheduling the function for hiding dropzone instead of calling it right away. Then, if another dragover or dragleave is fired, the scheduled function call is cancelled.
body.addEventListener('dragover', function() {
clearTimeout(body_dragleave_timeout);
show_dropzone();
}, false);
body.addEventListener('dragleave', function() {
clearTimeout(body_dragleave_timeout);
body_dragleave_timeout = setTimeout(show_upload_form, 100);
}, false);
dropzone.addEventListener('dragover', function(event) {
event.preventDefault();
dropzone.addClass("hover");
}, false);
dropzone.addEventListener('dragleave', function(event) {
dropzone.removeClass("hover");
}, false);
Solved ..!
Declare any array for ex:
targetCollection : any[]
dragenter: function(e) {
this.targetCollection.push(e.target); // For each dragEnter we are adding the target to targetCollection
$(this).addClass('red');
},
dragleave: function() {
this.targetCollection.pop(); // For every dragLeave we will pop the previous target from targetCollection
if(this.targetCollection.length == 0) // When the collection will get empty we will remove class red
$(this).removeClass('red');
}
No need to worry about child elements.
I struggeled a LOT with this, even after reading through all of these answers, and thought I may share my solution with you, because I figured it may be one of the simpler approaches, somewhat different though. My thought was of simply omitting the dragleave
event listener completely, and coding the dragleave behaviour with each new dragenter event fired, while making sure that dragenter events won't be fired unnecessarily.
In my example below, I have a table, where I want to be able to exchange table row contents with each other via drag & drop API. On dragenter
, a CSS class shall be added to the row element into which you're currently dragging your element, to highlight it, and on dragleave
, this class shall be removed.
Example:
Very basic HTML table:
<table>
<tr>
<td draggable="true" class="table-cell">Hello</td>
</tr>
<tr>
<td draggable="true" clas="table-cell">There</td>
</tr>
</table>
And the dragenter event handler function, added onto each table cell (aside dragstart
, dragover
, drop
, and dragend
handlers, which are not specific to this question, so not copied here):
/*##############################################################################
## Dragenter Handler ##
##############################################################################*/
// When dragging over the text node of a table cell (the text in a table cell),
// while previously being over the table cell element, the dragleave event gets
// fired, which stops the highlighting of the currently dragged cell. To avoid
// this problem and any coding around to fight it, everything has been
// programmed with the dragenter event handler only; no more dragleave needed
// For the dragenter event, e.target corresponds to the element into which the
// drag enters. This fact has been used to program the code as follows:
var previousRow = null;
function handleDragEnter(e) {
// Assure that dragenter code is only executed when entering an element (and
// for example not when entering a text node)
if (e.target.nodeType === 1) {
// Get the currently entered row
let currentRow = this.closest('tr');
// Check if the currently entered row is different from the row entered via
// the last drag
if (previousRow !== null) {
if (currentRow !== previousRow) {
// If so, remove the class responsible for highlighting it via CSS from
// it
previousRow.className = "";
}
}
// Each time an HTML element is entered, add the class responsible for
// highlighting it via CSS onto its containing row (or onto itself, if row)
currentRow.className = "ready-for-drop";
// To know which row has been the last one entered when this function will
// be called again, assign the previousRow variable of the global scope onto
// the currentRow from this function run
previousRow = currentRow;
}
}
Very basic comments left in code, such that this code suits for beginners too. Hope this will help you out! Note that you will of course need to add all the event listeners I mentioned above onto each table cell for this to work.
Here is another approach based on the timing of events.
The dragenter
event dispatched from the child element can be captured by the parent element and it always occurs before the dragleave
. The timing between these two events is really short, shorter than any possible human mouse action. So, the idea is to memorize the time when a dragenter
happens and filter dragleave
events that occurs "not too quickly" after ...
This short example works on Chrome and Firefox:
var node = document.getElementById('someNodeId'),
on = function(elem, evt, fn) { elem.addEventListener(evt, fn, false) },
time = 0;
on(node, 'dragenter', function(e) {
e.preventDefault();
time = (new Date).getTime();
// Drag start
})
on(node, 'dragleave', function(e) {
e.preventDefault();
if ((new Date).getTime() - time > 5) {
// Drag end
}
})
pimvdb..
Why don't you try out using drop instead of dragleave. It worked for me. hope this solves your problem.
Please check the jsFiddle : http://jsfiddle.net/HU6Mk/118/

Success story sharing
pointer-events: none
on the children. When I start dragging I append a class that has this property, when drag's over I remove the class. Worked nicely on Safari and Chrome, but not on Firefox.dragenter
I saveevent.currentTarget
in a new variabledragEnterTarget
. As long asdragEnterTarget
is set, I ignore furtherdragenter
events, because they are from children. In alldragleave
events I checkdragEnterTarget === event.target
. If this is false the event will be ignored as it was fired by a child. If this is true I resetdragEnterTarget
toundefined
.
