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 }))
}

document.cookie.split(";").forEach(function(c) { 
    document.cookie = c.replace(/^ +/, "").replace(/=.*/, "=;expires=" + new Date().toUTCString() + ";path=/"); 
});
//clearing local storage
localStorage.clear();

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。)

我想分享一下清除cookie的方法。也许这在某些时候对其他人是有帮助的。

var cookie = document.cookie.split(';');

for (var i = 0; i < cookie.length; i++) {

    var chip = cookie[i],
        entry = chip.split("="),
        name = entry[0];

    document.cookie = name + '=; expires=Thu, 01 Jan 1970 00:00:01 GMT;';
}

我们可以这样做:

deleteAllCookies=()=>
      {
      let c=document.cookie.split(';')
      for(const k of c)
         {
         let s=k.split('=')
         document.cookie=s[0].trim()+'=;expires=Fri, 20 Aug 2021 00:00:00 UTC'
         }
      }

用法:

deleteAllCookies()

截止日期是这个答案之前的任意一天;它可以是当天之前的任何日期 在JS中，你不能基于路径读取cookie 在JS中，你只能设置或获取cookie

这对我来说很管用:

function deleteCookie(name) {
  document.cookie = 
    `${name}=; Expires=Thu, 01 Jan 1970 00:00:01 GMT; Path=/`;

    // Remove it from local storage too
    window.localStorage.removeItem(name);
}

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

  cookies.forEach((cookie) => {
    const name = cookie.split("=").shift();
    this.deleteCookie(name);
  });

  // Some sites backup cookies in `localStorage`
  window.localStorage.clear();
}
