其中的delcookie在二级目录下无法删除cookie，主要原因是cookie也有作用域问题，需要加上对应的域名或者目录
所以delcookie修改方式改为：
- function delcookie(name) {
- var exp = new Date();
- exp.setTime (exp.getTime() - 1);
- var cval = getcookie(name);
- name = cookie_pre+name;
- document.cookie = name+"="+cval+";expires="+exp.toGMTString()+"; path=/";;
- }
