| Js操作Cookie的代码,下边的代码内有详细注释,这里就不再多说了,直接上代码: /* *设置与获取Cookie
 */
 var Cookie = {}
 //写入Cookie,key为键,value是值
 //duration过期时间(天为单位,默认1天)
 Cookie.write = function (key, value, duration)
 {
 Cookie.remove(key);
 var d = new Date();
 if (duration <= 0)
 duration = 1;
 d.setTime(d.getTime() + 1000 * 60 * 60 * 24 * duration);
 document.cookie = key + "=" + encodeURI(value) + "; expires=" + d.toGMTString() + ";path=/";
 };
 //移除Cookie,key为键
 Cookie.remove = function (key)
 {
 var d = new Date();
 if (Cookie.read(key) != "")
 {
 d.setTime(d.getTime() - (86400 * 1000 * 1));
 document.cookie = key + "=;expires=" + d.toGMTString();
 }
 };
 //更多教程:Veryhuo.Com
 //读取Cookie,key是键
 //不存在返回空字符串""
 Cookie.read = function (key)
 {
 var arr = document.cookie.match(new RegExp("(^| )" + key + "=([^;]*)(;|$)"));
 if (arr != null)
 return decodeURIComponent(arr[2]);
 return "";
 };
