How can I change the order of a list once applied by JavaScript jQuery.sortable
.
For example:
<ul id="mylist">
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ul>
var x_sortable_list = $("mylist").sortable();
Then, assuming this to work:
x_sortable_list.changeOrder([
{item:1, newOrder:2 },
{item:2, newOrder:1 },
{item:3, newOrder:3 }
]);
Like others have mentioned, this has nothing to do with the sortable() functionality. Instead you need to retrieve the items in the list, shift their positions and then clear and re-insert the list items again in their new order:
// Get your list items
var items = $('#mylist').find('li');
// The new index order for each item
var order = [4, 2, 0, 1, 3];
// Map the existing items to their new positions
var orderedItems = $.map(order, function(value) {
return items.get(value);
});
// Clear the old list items and insert the newly ordered ones
$('#mylist').empty().html(orderedItems);
As Sparr has said, there's no way to sort them using sortable
directly, but you can still move them manually with something like:
$("#mylist li:eq(1)").insertAfter($("#mylist li:eq(2)"));
The sortable provides a user interface for rearranging the items. To rearrange them programmatically you still need to manipulate the elements yourself, manually or with some other plugin.
