Try this (adapted from here):
试试这个（改编自这里）：
function DeleteCookie(name, path, domain)
{
path = (path ? ";path=" + path : "");
domain = (domain ? ";domain=" + domain : "");
var expiration = "Thu, 01-Jan-1970 00:00:01 GMT";
document.cookie = name + "=" + path + domain + ";expires=" + expiration;
}
Essentially, you delete cookies by setting their expiration date to a date guaranteed to be in the past.
本质上，您可以通过将 cookie 的到期日期设置为保证为过去的日期来删除 cookie。
