jQuery中Cookie的存取
-----------------------------------------------------------------------------------------------------------
//創建一個key為uName，值為cookievalue的cookie，有效期為3天
$.cookie("uName", "cookievalue", { expires: 3});
//讀取cookie值
$.cookie("uName");
//刪除cookie
$.cookie("uName", null);
注意：要記得引用兩個js文件
<script src="jquery-1.11.2.js" type="text/javascript"></script>
<script src="jquery.cookie-v1.4.1.js" type="text/javascript"></script>
