[AS2]Flash版本的Cookie类

利用Flash的SharedObject类的功能，来模拟Cookie的功能！

调用实例

view plain copy to clipboard print ?

import as2.util.Cookie;
//创建cookie对象,超时单位为毫秒;
var cookie:Cookie = new Cookie("myCookie", 24 * 60 * 60 * 1000);
//添加key值;
cookie.put("a", {a:"a0001"});
cookie.put("b", {b:2});
//查key是否存在;
trace(cookie.contains("a"));
//删除key;
cookie.remove("a");
trace(cookie.contains("a"));
//获取key的值
trace(cookie.get("b").b);
//清除cookie所有的值;
cookie.clear();
