Question

Is there a way to get information if an element that’s draggable is reverted?

I’m stuck on this. I want to make an element droppable again, but only if the draggable that was lying there is moved elsewhere (meaning doesn’t revert).

Doesn’t looks like jQuery UI has support for it so you could add it yourself like this:

$.ui.draggable.prototype._mouseStop = function(event) {
    //If we are using droppables, inform the manager about the drop
    var dropped = false;
    if ($.ui.ddmanager && !this.options.dropBehaviour)
        dropped = $.ui.ddmanager.drop(this, event);

    //if a drop comes from outside (a sortable)
    if(this.dropped) {
        dropped = this.dropped;
        this.dropped = false;
    }

    if((this.options.revert == "invalid" && !dropped) || (this.options.revert == "valid" && dropped) || this.options.revert === true || ($.isFunction(this.options.revert) && this.options.revert.call(this.element, dropped))) {
        var self = this;
        self._trigger("reverting", event);
        $(this.helper).animate(this.originalPosition, parseInt(this.options.revertDuration, 10), function() {
            event.reverted = true;
            self._trigger("stop", event);
            self._clear();
        });
    } else {
        this._trigger("stop", event);
        this._clear();
    }

    return false;
}

Would allow you to do this:

$(document).ready(function($) {
    $('#draggable').draggable({
        revert: true,
        reverting: function() {
            console.log('reverted');
        },
        stop: function(event) {
            if (event.reverted) {
                console.log('reverted');
            }
        }
    });
});
