当可拖动插件的实例被销毁(或之前的步骤)时,是否有任何可能的方法来删除可拖动插件所做的所有更改?我尝试做类似的事情:

if (target) {
      $(target).draggable("option","revert",true);
      $(target).draggable("destroy");
}

不工作。

我的猜测是,在我更改了 revert 选项之后,它基本上设置了元素现在所在的起点,而不是它最初所在的位置。

  $(editbtn).toggle(
                function() {

                    //appedning editor to body
                    editor.draggable().appendTo($('body'));
