每次访问仅显示一次弹出窗口

您也可以使用localstorage.要设置存储项目:localStorage.setItem('myPopup','true');并检查它,您可以执行以下操作:

var poppy = localStorage.getItem('myPopup');

if(!poppy){
    function PopUp(){
        $('.home-popup').fadeIn(500);
    }

    setTimeout(function(){
        PopUp();
    },1000); // 1000 to load it after 1 second from page load

    $('.close-popup-btn').click(function() {
        $('.popup').fadeOut(300);
    });
    localStorage.setItem('myPopup','true');
}
