javascript - ui.draggable ("destroy"的 jquery ui 错误)

Question

我想删除 <div> 的拖动属性当我把它放在容器上时。但是我得到一个错误 "Property 'draggable' of object #<Object> is not a function" ，下面是我的代码。

$( "#fighter1" ).draggable(); //fighter1 is the id of draggable object
$( "#fighter2" ).draggable();
$( "#fighter3" ).draggable();
$( "#fighter4" ).draggable();
$( "#fighter5" ).draggable();
$( "#fighter6" ).draggable();
$( "#dest" ).droppable({      //dest is the id of droppable object
   drop: function( event, ui ) {
      ui.draggable("destroy"); //I get error here.
   }
});

我使用的jquery ui版本是1.8.12

Answer 1

我的猜测是“ui”是一个简单的旧 javascript 对象而不是 jQuery 对象。
尝试(修订):
$(ui.draggable).draggable("destroy");
