每个会话仅显示一次jQuery [英] Only show jQuery once per session

问题描述

因此，我使用以下代码来显示和淡入一个元素.我已将div设置为在主页上可见，并在所有其他页面上隐藏，因此div仅显示在主页上.我的问题是，每次我访问首页时，div都会显示出来.相反，我只想在每个会话中仅向div显示一次.我试图用Cookie修复它，但是没有用.

So I use the following code to show and fade an element. I have set the div on visible on the homepage and hidden on all other pages so the div only shows up on the homepage. My problem is, everytime I visit the homepage, the div will show up. Instead I would like to show the div only once per session. I've tried to fix it with cookies but it didn't work.

$(window).load(function(){
$("#testlay").fadeIn('slow').delay(1000).fadeOut(1600);
});

function createCookie(name,value,days) {
        if (days) {
            var date = new Date();
            date.setTime(date.getTime() + (days*24*60*60*1000));
            var expires = "; expires=" + date.toUTCString();
        }
        else var expires = "";
        document.cookie = name + "=" + value + expires + "; path=/";
    }

    function readCookie(name) {
        var nameEQ = name + "=";
        var ca = document.cookie.split(';');
        for(var i=0;i < ca.length;i++) {
            var c = ca[i];
            while (c.charAt(0)==' ') c = c.substring(1,c.length);
            if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
        }
        return null;
    }

    function eraseCookie(name) {
        createCookie(name,"",-1);
    }
    //your window load function replace with below
    $(function(){
      if(readCookie('CodefireOnce') == null)
      {
        createCookie('CodefireOnce','true',7);
        $("#testlay").fadeIn('slow').delay(1000).fadeOut(1600);
      }
    });
