Many thanks for your explaination.
There's something I don't understand about the scriptaculous API. May
be because
I'm a Java developer ;-)
Why do we have to do such things:
- Draggables.addObserver( ... )
or
- Sortable.onEmptyHover = function( ... ){ }
If I correctly understand the first one will be called for any drag on
a given element
The second will be called for any call to Sortable.onEmptyHover()
-> So If there is 2 drag action the observer will be called twice ?
That's strange ? Why the API doesn't allow to plug observer to the
Draggable or Sortable instance instead of the static "Class" ?
Something like:
var sortable = Sortable.create(....)
sortable.onEmptyHover = function( ... ){ }
Regards,
Jp

Your best bet is to attach an observer, which may look something like
this:
var MyDragObserver = Class.create();
MyDragObserver.prototype = {
initialize: function(element) {
this.element = $(element);
},
onEnd: function (eventName, draggable, event) {},
onStart: function (eventName, draggable, event) {},
onDrag: function (eventName, draggable, event) {}
}
Draggables.addObserver(new MyDragObserver(elementId));
Or even be simpler:
Draggables.addObserver({onStart: someFunction, onDrag:
someOtherFunction});
Contrary to my previous advice, you may wish to set the flag on drag
rather than on start.
