jQuery Sortable and Droppable
I want to have a list that is sortable, but I also want the elements in that list to be droppable to the divs I have defined as droppable. I can't seem to find a way to do it. Any ideas?
Answer
Here's a simplified version of Colin's solution.
The biggest difference is that this solution does not store the entire html of the sortable elements, but only the currently dragged item. It is then inserted into it's original position if the item is dropped on the droppable area.
Anyway, here's the code:
<!doctype html>
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.5/jquery-ui.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var dropped = false;
var draggable_sibling;
$("#sortable").sortable({
start: function(event, ui) {
draggable_sibling = $(ui.item).prev();
},
stop: function(event, ui) {
if (dropped) {
if (draggable_sibling.length == 0)
$('#sortable').prepend(ui.item);
draggable_sibling.after(ui.item);
dropped = false;
}
}
});
$(".droppable").droppable({
activeClass: 'active',
hoverClass:'hovered',
drop:function(event,ui){
dropped = true;
$(event.target).addClass('dropped');
}
});
});
</script>
<style type="text/css">
#sortable li{
clear:both;
float:left;
}
.droppable {
clear:both;
height:300px;
width:400px;
background-color:#CCC;
}
.droppable.active { background: #CFC; }
.droppable.hovered { background: #CCF; }
.dropped { background: #f52; }
</style>
</head>
<body>
<ul id="sortable">
<li id="one">One</li>
<li id="two">Two</li>
<li id="three">Three</li>
<li id="four">Four</li>
<li id="five">Five</li>
<li id="six">Six</li>
</ul>
<div class="droppable">Drop Here</div>
<div class="droppable">Drop Here</div>
</body>
</html>
It still suffers the same problem as Colin's solution if an item is dragged into a new position in the list and then dropped outside both the <ul> and the droppable <div>. The item will then not reset but take the last position in the list (tested in Google Chrome). Anyway, this is easily solved with some mouse over detection or it may even be desirable behaviour.
