Set the cookie function directly to the code: 

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

Set the cookie:

setCookie("key", 'value', 1);

Cookie detection:

document.cookie.indexOf("key")

The return value -1 indicates that this cookie does not exist
