类似于当当网的发货以后的那个发货反馈，鼠标移上去后自动会弹出一个框，位置随位置的改变而改变，代码如下：

function showdetails(thisObj,orderid){
var d = $(thisObj);
var pos = d.offset();
var t = pos.top + d.height() + 5; // 弹出框的上边位置
var l = pos.left + d.width() + 5; // 弹出框的左边位置
$("#details").css({ "top": t, "left": l }).show();
$("#details").html("订单 "+orderid+" 的内容！");
}
</script>
</head>
<body>
