Modify document.cookie in Chrome console not working
提问by bigbearzhu
Can I modify document.cookie in the console of Chrome Developer Tools?
我可以在 Chrome 开发者工具的控制台中修改 document.cookie 吗？
My current cookie string was like:
我当前的 cookie 字符串是这样的：
"coldcookie="
It seems it just doesn't work if I run this code below:
如果我在下面运行此代码，它似乎不起作用：
document.cookie = document.cookie + "; newcookie=something"
The document.cookie wouldn't change at all.
document.cookie 根本不会改变。
Update: I found that if I run:
更新：我发现如果我运行：
document.cookie = "newcookie"
It actually add a "newcookie" in the cookie string like:
它实际上在 cookie 字符串中添加了一个“newcookie”，例如：
"oldcookie=; newcookie"
Shouldn't that clear the current cookie string?
这不应该清除当前的 cookie 字符串吗？
It does the same thing in IE. So I think there must be some rule there. Any ideas?
它在 IE 中做同样的事情。所以我认为那里必须有一些规则。有任何想法吗？

Cookies are set to expire, since we can't really "delete" them, we just force them to expire with a past date.
Cookie 设置为过期，因为我们无法真正“删除”它们，我们只是强制它们在过去的日期过期。
function deleteCookie(name) {
document.cookie = name + '=;expires=Thu, 05 Oct 1990 00:00:01 GMT;';
};
deleteCookie('newcookie')
