支持中文添加不会乱码，可以用unescape、escape或是encodeURI、decodeURI进行编码转换就可以解决乱码。

//用法：
//一、设置cookie
var cookie = new Cookies();
function set() {
//普通设置
cookie.set("key1", "哈哈3");
//过期时间为一年
var d = new Date();
d.setFullYear(d.getFullYear() + 1);
cookie.set("key2", "val2", d);
//设置域及路径，带过期时间
cookie.set("key3", "val3", d, "casett", "/");
//设置带子键的cookie,子键分别是k1,k2,k3
cookie.set("key4", "k1=哈哈是&k2=2&k3=3");
};
//二、读取cookie
//简单获取
function get() {
alert(cookie.get("key1"));
alert(cookie.get("key2"));
alert(cookie.get("key3"));
alert(cookie.get("key4"));
//获取key4的子键k1值
alert(cookie.getChild("key4","k1"));
alert(cookie.getChild("key4","k2"));
}
//三、删除
function remove() {
cookie.remove("key1");
cookie.remove("key2");
cookie.remove("key3");
cookie.remove("key4");
}
