        var date = new Date();
        var expiresDays = 24;
        date.setTime(date.getTime() + expiresDays * 24 * 3600 * 1000);
        document.cookie = "userId=自己设置的Cookie内容" + ";expires" + date.toGMTString();
    }
    function getCookie(key) {
        var getCookie = document.cookie.replace(/[]/g, "");
        var arrCookie = getCookie.split(";")
        var tips;
        for (var i = 0; i < arrCookie.length; i++) {
            var arr = arrCookie[i].split("=");
            if (key == arr[0]) {
                tips = arr[1];
                break;
            }
        }
