I am using the jQuery UI Draggable/Sortable demo (http://jqueryui.com/demos/draggable/#sortable) for the basis of my project. I need to get a reference to the <li>
that gets cloned into the sortable when the sortable receives it. I tried the sortable's receive event, but that only gives a reference to the original draggable <li>
, and not its clone.
In the demo you reference, there's actually a bug; after you drag an item down it inserts a cloned li
with an id
which is a duplicate of its brother's into the DOM, so beware (a bug was filed about this but there's no activity around it).
I did a few things to achieve this:
To get around the limitation of the demo that I described above, instead apply a class
to the draggable items that will be linked to the sortable
:
<ul>
<li class="new-item ui-state-highlight">Drag me down</li>
</ul>
Make items with that class draggable, instead of selecting an element by id
:
$(".new-item").draggable({
connectToSortable: "#sortable",
helper: "clone",
revert: "invalid"
});
Tap into the stop
event of the sortable, and perform some simple logic about the item that was dropped, leveraging the fact that an item with the class new-item
could only have been dropped (and isn't simply an existing item in the sortable):
$("#sortable").sortable({
revert: true,
stop: function(event, ui) {
if (ui.item.hasClass("new-item")) {
// This is a new item
ui.item.removeClass("new-item");
ui.item.html("<b>HI</b>");
}
}
});
Note that you could use the data-*
attribute instead of adding a helper class.
Here's a working example: http://jsfiddle.net/andrewwhitaker/twFCu/
Hope that helps.
