Question: Is there a way in Laravel to do some check on associating?

For example I've `Home` and `Owner`, I would like on `associate` check if `Home` as already an `Owner`, and in that case I must execute some code...

Some suggestions?

Answer: 
You should use `event.stopPropagation();` who prevents the event from beeing trigger with the children elements.

There is the doc : <https://api.jquery.com/event.stoppropagation/>
Its a Firefox-Bug. In Firefox the "Dragenter-Event" gets fired twice. No matter if there is any child-element or not.
You could try to work with event.target and event.currentTarget in combination with pointer-events: none.
