函数方法+ ES6

const cookieCleaner = () => {
  return document.cookie.split(";").reduce(function (acc, cookie) {
    const eqPos = cookie.indexOf("=");
    const cleanCookie = `${cookie.substr(0, eqPos)}=;expires=Thu, 01 Jan 1970 00:00:00 GMT;`;
    return `${acc}${cleanCookie}`;
  }, "");
}

注意:不处理路径

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。

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 }))
}

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
}

const cookieCleaner = () => {
  return document.cookie.split(";").reduce(function (acc, cookie) {
    const eqPos = cookie.indexOf("=");
    const cleanCookie = `${cookie.substr(0, eqPos)}=;expires=Thu, 01 Jan 1970 00:00:00 GMT;`;
    return `${acc}${cleanCookie}`;
  }, "");
}

注意:不处理路径

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

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

注意，这段代码有两个限制:

它不会删除设置了HttpOnly标志的cookie，因为HttpOnly标志禁止Javascript访问cookie。 它不会删除已设置为Path值的cookie。(尽管这些cookie会出现在文档中。cookie，但你不能删除它没有指定相同的路径值，它是设置。)
