jQuery UI可排序刷新不会触发更新？

Question

update: function(event, ui) {
            console.dir("update");    
        },

Why update is not triggered by:

$(...).sortable('refresh');

?

And if it's not supposed to, than how to I trigger event after refresh?

Answer 1

You can add .trigger('update') if you wish.

I would question why a refresh requires an update . Maybe better to have the functionality elsewhere and call it after the refresh.
