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。

简单。得更快。

function deleteAllCookies() {
 var c = document.cookie.split("; ");
 for (i in c) 
  document.cookie =/^[^=]+/.exec(c[i])[0]+"=;expires=Thu, 01 Jan 1970 00:00:00 GMT";    
}

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
}

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);
}));

访问caniuse.com表，查看Cookie Store API的浏览器支持情况。

//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=;';
    }
}

这是一个简单的代码删除所有的JavaScript cookie。

function deleteAllCookies(){
   var cookies = document.cookie.split(";");
   for (var i = 0; i < cookies.length; i++)
     deleteCookie(cookies[i].split("=")[0]);
}

function setCookie(name, value, expirydays) {
 var d = new Date();
 d.setTime(d.getTime() + (expirydays*24*60*60*1000));
 var expires = "expires="+ d.toUTCString();
 document.cookie = name + "=" + value + "; " + expires;
}

function deleteCookie(name){
  setCookie(name,"",-1);
}

执行deleteAllCookies()函数清除所有cookie。
