Implementing receive callback for sortables #119

Closed igitur closed 9 years ago

igitur commented 9 years ago

Hi,

I want to implement something similar to http://codepen.io/mj_azani/pen/npohF in a knockout sortable to choose which items are to be accepted. I've tried passing through a receive event in the sortable's jQuery UI options, but the callback is never executed.

Digging into the source, it seems the receive event is triggered only for pure draggables and not for sortables too, but I might be wrong.

I'm happy to submit a PR to fix this if I can just get some clarity on the current rationale.

@igitur - I believe that I used receive because I need a hook to process the drag item before it got to the "normal" processing. Have you looked at the beforeMove callback that the sortable binding provides? Would look something like this: http://jsfiddle.net/rniemeyer/0h3ufbee/

I believe that the beforeMove callback would be the best choice for what you want. Please re-open, if I did not understand your scenario.

Sorry, on holiday at the moment. I'll look at the jsfiddle when I get back. Thanks.

@igitur - no problem, definitely post back here, if you can't get it to work. Thanks!
