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。)

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
}

//Delete all cookies
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 00:00:01 GMT;' +
            'path=' + '/;' +
            'domain=' + window.location.host + ';' +
            'secure=;';
    }
}

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))
    }
  )
} 

一个衬套

以防你想快速粘贴进去…

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

和bookmarklet的代码:

javascript:(function(){document.cookie.split(";").forEach(function(c) { document.cookie = c.replace(/^ +/, "").replace(/=.*/, "=;expires=" + new Date().toUTCString() + ";path=/"); }); })();
