使用 JavaScript 清除所有 cookie [英] Clearing all cookies with JavaScript

问题描述

如何使用 JavaScript 删除当前域的所有 cookie?

How do you delete all the cookies for the current domain using JavaScript?

推荐答案

function deleteAllCookies() {
    var cookies = document.cookie.split(";");

    for (var i = 0; i < cookies.length; i++) {
        var cookie = cookies[i];
        var eqPos = cookie.indexOf("=");
        var name = eqPos > -1 ? cookie.substr(0, eqPos) : cookie;
        document.cookie = name + "=;expires=Thu, 01 Jan 1970 00:00:00 GMT";
    }
}

请注意，此代码有两个限制:

Note that this code has two limitations:

• 它不会删除设置了 HttpOnly 标志的 cookie，因为 HttpOnly 标志会禁用 Javascript 对 cookie 的访问.
• 它不会删除使用 Path 值设置的 cookie.(尽管这些 cookie 会出现在 document.cookie 中，但如果不指定与设置它相同的 Path 值，就无法删除它.)

• It will not delete cookies with HttpOnly flag set, as the HttpOnly flag disables Javascript's access to the cookie.
• It will not delete cookies that have been set with a Path value. (This is despite the fact that those cookies will appear in document.cookie, but you can't delete it without specifying the same Path value with which it was set.)
