javascript事件对象目标字段的值不同于event.target

Question

为什么返回到jquery回调的事件对象（e）包含值为（{}}的“target”字段，但在以e记录时会产生url（“http://www.myurl.com”）。目标

“target”字段不应包含与e.target相同的值吗？它是如何工作的？我很困惑。

$('.ckfilter').click(function(e){

   e.preventDefault();   

   console.log("e:",e);
   console.log("e.target:",e.target);
});


e: 
({originalEvent:({}), 
  type:"click", 
  isDefaultPrevented:function K() {return !0;}, 
  timeStamp:22619729,

  data:null, 
  handleObj:{type:"click", 
             origType:"click", 
             data:null, 
             handler:(function (e) {e.preventDefault(); }),
              guid:18, 
              selector:null, 
              quick:null, 
              namespace:""}
}) 


e.target: "http://www.myurl.com"
