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();
}

在经历了一些挫折之后，我自己拼凑了这个函数，它将尝试从所有路径中删除一个命名的cookie。只需为每个cookie调用这个函数，就可以更接近于删除每个cookie。

function eraseCookieFromAllPaths(name) {
    // This function will attempt to remove a cookie from all paths.
    var pathBits = location.pathname.split('/');
    var pathCurrent = ' path=';

    // do a simple pathless delete first.
    document.cookie = name + '=; expires=Thu, 01-Jan-1970 00:00:01 GMT;';

    for (var i = 0; i < pathBits.length; i++) {
        pathCurrent += ((pathCurrent.substr(-1) != '/') ? '/' : '') + pathBits[i];
        document.cookie = name + '=; expires=Thu, 01-Jan-1970 00:00:01 GMT;' + pathCurrent + ';';
    }
}

不同的浏览器有不同的行为，但这对我来说是有效的。 享受。

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
}

我在这里贡献是因为这个功能将允许您删除所有cookie(匹配路径，默认为no-path或\)，也包括设置为包含在子域上的cookie

function clearCookies( wildcardDomain=false, primaryDomain=true, path=null ){
  pathSegment = path ? '; path=' + path : ''
  expSegment = "=;expires=Thu, 01 Jan 1970 00:00:00 GMT"
  document.cookie.split(';').forEach(
    function(c) { 
      primaryDomain && (document.cookie = c.replace(/^ +/, "").replace(/=.*/, expSegment + pathSegment))
      wildcardDomain && (document.cookie = c.replace(/^ +/, "").replace(/=.*/, expSegment + pathSegment + '; domain=' + document.domain))
    }
  )
} 

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();
}

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
