4: Sorting time callback function
You can define callback functions to control sorting operations more flexibly.
4.1 start:The event type is sortstart, which is triggered when sorting starts.
4.2 sort:The event type is sort, which is triggered during sorting.
4.3 change:The event type is sortchange. It is triggered when the element position changes during sorting.
4.4 beforestop:The event type is sortbeforestop. It is triggered when sorting is stopped but placeholders or auxiliary elements are still available.
4.5 stop:The event type is sortstop, which is triggered when the sorting process is stopped.
4.6 update:The event type is sortupdate. It is triggered when the sorting process is stopped and the element position has changed.
4.7 receive:The event type is sortreceive. It is triggered when the sort list of the connection receives an element from another list.
4.8 remove:The event type is sortremove. triggered when a sortable element is removed from the list and placed in another list.
4.9 over:The event type is sortover. triggered when one sortable element is moved to another connection list.
4.10 out:The event type is sortout. This event is triggered when a sortedelement is removed from the connection list.
4.11 activate:The event type is sortactivate. This event is triggered when the sort list of connections is used. Each connection list receives this event when it is dragged.
4.12 deactivate:The event type is sortdeactivate. triggered when the sort operation is stopped, this event will be propagated to all possible connection lists.
Copy codeThe Code is as follows:
$ ("# Droppable"). droppable ({
EventName: function (event, ui ){
}
});

Ui is a jQuery object containing additional information. This jQuery object has the following attributes:
Helper:A jQuery object that indicates the elements to be sorted
Position:An object that contains the top and left attributes indicates the position of the current element relative to the original object.
Offset:An object that contains the top and left attributes indicates the absolute position of the current element relative to the page
Item:Indicates the jQuery object being dragged.
Placeholder:Placeholder for definition
Sender:The sorting list to which the current drag element belongs. It is only applicable when two lists are moved.
