javascript - jQuery UI: Set class for draggable when valid -

-

i know can set class dropable object when valid dragable hovering, using hoverclass. posible that, draggable object (just when hovering on valid target)?

ok, managed using events in dropable:

el.dropable({    accept: ".target",    over: function(e, ui){        ui.draggable.addclass("valid");    },    out: function(e, ui){        ui.draggable.removeclass("valid");    },    hoverclass: "valid" });
