推荐答案

您无法通过来自其他域的Javascript删除Cookie比你当前的页面。这是一个浏览器安全功能。并且，如果cookie被标记为特定路径，则只能从该特定路径上的页面访问它（即使是来自同一个域）。

You cannot delete cookies via Javascript that come from other domains than the page you are currently on. This is a browser security feature. And, if a cookie is marked for a particular path, you can only access it from a page on that particular path (even from the same domain).

并且，对于标记为 HttpOnly （例如服务器端只访问cookie），你甚至不能通过javascript删除你自己域名的那些。

And, for cookies that are marked HttpOnly (e.g. server-side access only cookies), you can't even delete those for your own domain via javascript.

清除所有cookie的唯一方法是您（用户）使用浏览器的用户界面删除cookie或将浏览器配置为在关闭浏览器时自动清除cookie。

The only way to clear all cookies is for you (the user) to use the browser's user interface to delete the cookies or to configure your browser to automatically clear cookies when you close the browser.
