Draggable and afterReceive

[rniemeyer]

Hi Chris-
I'll take a look at this one. Is there a specific scenario that you are trying to handle? The afterMove and beforeMove handlers do still get called for draggables, so I wanted to see if maybe they were appropriate for your situation.

Thanks!

I needed a way to distinguish between an being item moved in the sortable and a new item being added from a draggable - the processing needs to be different - setting up computed observables etc, updating the server etc.

By adding in the afterReceive callback as above I can handle my situation without needing to add anything else specific to the knockout-sortable code.

I found I could do this with the afterMove but it felt more like a hack where I have to test to see if the item was new or not - afterReceive was just much cleaner and enabled me to nicely tidy up my code.

OK- thanks for the explanation. I will look at getting this into the library.

I added a new callback called dragged. The afterReceive event is triggered for both items that are dragged from a draggable or from another sortable list. I wanted this callback to be specific to dragged items. The callback is provided the dragItem, event, and ui objects. If the function returns a value, then it will be used as the dragItem, which could be used as an alternative to providing a clone function on the object.

Do you have an example of using it? I cant use dragged callback.

@josx - the dragged callback is specified on a sortable binding like:

<div data-bind="sortable: { data: items, dragged: onDraggedItemDropped }"></div>

Here is a sample: http://jsfiddle.net/rniemeyer/Lpazw/

Thanks a lot :)
