你可以通过查看文档得到一个列表。饼干变量。清除它们只是一个循环遍历所有它们并一个一个地清除它们的问题。

这里有一个清除所有路径和所有变体域(www.mydomain.example, mydomain。例等):

(function () {
    var cookies = document.cookie.split("; ");
    for (var c = 0; c < cookies.length; c++) {
        var d = window.location.hostname.split(".");
        while (d.length > 0) {
            var cookieBase = encodeURIComponent(cookies[c].split(";")[0].split("=")[0]) + '=; expires=Thu, 01-Jan-1970 00:00:01 GMT; domain=' + d.join('.') + ' ;path=';
            var p = location.pathname.split('/');
            document.cookie = cookieBase + '/';
            while (p.length > 0) {
                document.cookie = cookieBase + p.join('/');
                p.pop();
            };
            d.shift();
        }
    }
})();

Jquery:

var cookies = $.cookie();
for(var cookie in cookies) {
$.removeCookie(cookie);
}

香草JS

function clearListCookies()
{   
 var cookies = document.cookie.split(";");
 for (var i = 0; i < cookies.length; i++)
  {   
    var spcook =  cookies[i].split("=");
    deleteCookie(spcook[0]);
  }
  function deleteCookie(cookiename)
   {
    var d = new Date();
    d.setDate(d.getDate() - 1);
    var expires = ";expires="+d;
    var name=cookiename;
    //alert(name);
    var value="";
    document.cookie = name + "=" + value + expires + "; path=/acc/html";                    
}
window.location = ""; // TO REFRESH THE PAGE
}

下面的代码将删除当前域内的所有cookie和所有尾随子域(www.some.sub.domain.example， .some.sub.domain。例如,.sub.domain。例如，等等。)

一个单行的香草JS版本(我认为这里唯一一个没有使用cookie.split()):

document.cookie.replace(/(?<=^|;).+?(?=\=|;|$)/g, name => location.hostname.split('.').reverse().reduce(domain => (domain=domain.replace(/^\.?[^.]+/, ''),document.cookie=`${name}=;max-age=0;path=/;domain=${domain}`,domain), location.hostname));

这是这一行的一个可读版本:

document.cookie.replace(
  /(?<=^|;).+?(?=\=|;|$)/g,
  name => location.hostname
    .split(/\.(?=[^\.]+\.)/)
    .reduceRight((acc, val, i, arr) => i ? arr[i]='.'+val+acc : (arr[i]='', arr), '')
    .map(domain => document.cookie=`${name}=;max-age=0;path=/;domain=${domain}`)
);

如果你想使用js-cookie npm包并按名称删除cookie:

import cookie from 'js-cookie'

export const removeAllCookiesByName = (cookieName: string) => {
  const hostParts = location.host.split('.')
  const domains = hostParts.reduce(
    (acc: string[], current, index) => [
      ...acc,
      hostParts.slice(index).join('.'),
    ],
    []
  )
  domains.forEach((domain) => cookie.remove(cookieName, { domain }))
}

如果你只关心清除安全源上的Cookie，你可以使用Cookie Store API和它的.delete()方法。

cookieStore.getAll().then(cookies => cookies.forEach(cookie => {
    console.log('Cookie deleted:', cookie);
    cookieStore.delete(cookie.name);
}));
