Hello,
I am experiencing exactly the same behavior.
As shown in the code I tried to get all the "<li> elements" into the array
"items" and make it "unique", but not even that worked.
(see Source Code).
The only solution was the proposed one:
$(this).children(":last").remove();
Is there any new idea how this could work without a workaround?
Cheers and thanks,
Robert
<code>
jQuery('.sort').sortable({
receive: function(event, ui) {
var items = [];
jQuery('.sort li').each(function(n,item) {
items.push(item.innerHTML);
});
plotGraph(items);
},
update: function(event, ui) {
var items = [];
//$(this).children(":last").remove();
jQuery('.sort li').each(function(n,item) {
items.push(item.innerHTML);
});
items = jQuery.unique(items);
plotGraph(items);
}
});
