html页面设置一个跟随鼠标移动的DIV(jQuery实现)

说明业务:鼠标放到某个标签上,显示一个div,并跟随鼠标移动

html页面(直接放body里面):

      <a href="#" id="'+data[i].refundId+'"OrderInform"" data-placement="right" onmouseover="tip.start(this)" style="color:#00FFCC;left:;top:;"> 测试标签</span></a>

        <div class="" id="OrderInform" style="position:absolute;display:none;width:217px;height:500px;border:solid 5px #000000">测试框</div>

jQuer:

var tip={ 

  $:function(ele){
  if(typeof(ele)=="object")
  return ele;
  else if(typeof(ele)=="string"||typeof(ele)=="number")
  return document.getElementById(ele.toString());
  return null;
  },
  mousePos:function(e){
  var x,y;
  var e = e||window.event;
  return{ x:e.clientX+document.body.scrollLeft+document.documentElement.scrollLeft,
  y:e.clientY+document.body.scrollTop+document.documentElement.scrollTop};
  },
  start:function(obj){
  var self = this;
  obj.onmousemove=function(e){
  console.log(e)
  var mouse = self.mousePos(e);
  console.log(mouse)
  var left= mouse.x + 'px';
  var top= mouse.y + 'px';

  if(mouse.y+400>900){
  top=mouse.y-500+'px';
  }

  $("#OrderInform").css({'top':top,'left':left});
  $("#OrderInform").show();
};
obj.onmouseout=function(){
$("#OrderInform").hide(); //失去焦点关闭
};
}
}

 (没有太按语法结构来弄,但是主要代码都在上面)
