user interface - Jquery ui, call start drag manually

Question

In Jquery UI I can configure an element as draggable by invoking

$("#drag").draggable();

But is there a way to start and stop the drag functions manually from another function? Ie

someOtherFunction = function() {
  $("#drag").startdrag();
}
yetAnotherFunction = function() {
  $("#drag").stopdrag();
}

Answer 1

Answers above seem overcomplicated.

$('.nonDraggableObjectWhichTriggersDrag').mousedown(function(e) {
    $('.draggableObject').trigger(e); 
});
