Question

当用户首次访问该网站时，我会弹出一个年龄验证。第一次访问该网站时，我想弹出框，除非再次关闭浏览器并返回该网站，否则我不会再询问。到目前为止，它可以正常工作，弹出并创建cookie。当我访问网站上的其他页面并继续弹出时，它无法识别cookie。

function getBaseUrl(){return window.location.protocol+"//"+window.location.host}function getTemplate(e){var n=getBaseUrl()+handlebarTemplatesPath+e+".hbs";return jQuery.get(n).then(function(e){return Handlebars.compile(e)})}var handlebarTemplatesPath="/templates/components/common/";addAgeVerifyToBody=function(){getTemplate("age-verify").done(function(e){jQuery("body").append(e)})},jQuery(document).ready(function(){"true"!=Cookies.get("age-verified")&&addAgeVerifyToBody()}),overAge=function(){jQuery("#age-verify").addClass("hidden"),Cookies.set("age-verified","true")},underAge=function(){jQuery("#age-verify").addClass("under")},goBack=function(){window.history.back()};

尝试这样的事情：

    $(document).ready(function(){

        window.onload = function() {
           checkCookie();
        };

        function getCookie(cname) {
            var name = cname + "=";
            var decodedCookie = decodeURIComponent(document.cookie);
            var ca = decodedCookie.split(';');
            for(var i = 0; i < ca.length; i++) {
                var c = ca[i];
                while (c.charAt(0) == ' ') {
                    c = c.substring(1);
                }
                if (c.indexOf(name) == 0) {
                    return c.substring(name.length, c.length);
                }
            }
            return "";
        }
        function checkCookie() {
            var user=getCookie("age-verified");
            if (user != "") {
                $("#age-verify").addClass("hidden");
            }
        }
        

        var yesEl = document.getElementById('yes');
        var noEl = document.getElementById('no');

        yesEl.addEventListener('click', function(){
            //document.cookie = 'age-verified; expires=1';
            $('#age-verify').addClass('hidden');
            function setCookie(cname,cvalue,exdays) {
                var d = new Date();

                var expires = "expires=" + d.toGMTString();
