I'm using jquery UI draggable. I do some works in drag function. for example I scale the dragging element according to it's position. I want to drag elements automatically to certain (x, y) (something like jquery animate({left:x, top:y}, 1000)); but I want to trigger drag function and scale element when is animating. how can I do this?

I suggest another approach to do that.
Use an external function to do the scale effect, and call it from both events (drag and animate):
var $myDraggable = $('#draggable').draggable({
drag: function( event, ui ) {
scale(ui.offset.left, ui.offset.top);
}
});
$('button').on('click', function(){
$myDraggable.animate(
{ left:100, top:100 },
{
duration: 1000,
progress: function(draggable){
scale(draggable.elem.offsetLeft, draggable.elem.offsetTop);
}
});
});
function scale(left, top){
//your scaling logic here
console.log("scaling", left, top);
}
See this example: FIDDLE

PS:This code offer a button toggle function
$(function(){
$button = $('button')
$box = $('.box')
$click = 0
$button.click(function(){
if($click !=0){
$click ++
$box.removeClass('active')
}else{
$click --
$box.addClass('active')
}
});
});
