使用方法
1 //设置cookie
2 CookieUtil.set("name", "Nicholas"
);
3 CookieUtil.set("book", "Professional JavaScript"

));
7 console.log(CookieUtil.get("book"
));
8
9 //删除cookie
10 CookieUtil.unset("name"
);
11 CookieUtil.unset("book"
);
12
13 //设置1个cookie,包括它的路径、域、截止日期
14 CookieUtil.set("name", "Nicholas", "/books/projs/", "www.wrox.com",
new Date("January 1, 2010"
));
15
16 //删除同一cookie
17 CookieUtil.unset("name", "/books/projs/", "www.wrox.com"
);
