B2主题添加右下角会员活动弹窗

效果图:

原版自己试一下就好了，原来是有一个活动倒计时的，因为我这里直接标了日期就把倒计时去掉了，各位可根据自身需求自行调整

教程：

首先是原版的代码:

<script>
      window.onload = function () {
          countDown();
          function addZero(i) {
              return i < 10 ? "0" + i: i + "";
          }
          function countDown() {
              var nowtime = new Date();
              var endtime = new Date("此处填写截至日期格式为xxxx/xx/xx");
              var lefttime = parseInt((endtime.getTime() - nowtime.getTime()) / 1000);
              var d = parseInt(lefttime / (24*60*60))
              var h = parseInt(lefttime / (60 * 60) % 24);
              var m = parseInt(lefttime / 60 % 60);
              var s = parseInt(lefttime % 60);
              d = addZero(d)
              h = addZero(h);
              m = addZero(m);
              s = addZero(s);
              document.querySelector(".count").innerHTML = `活动倒计时  ${d}天 ${h} 时 ${m} 分 ${s} 秒`;
              if (lefttime <= 0) {
                  document.querySelector(".count").innerHTML = "<style>.Ji-col{display: none;}</style>";
                  return;
              }
              setTimeout(countDown, 1000);
            }
        }
    </script>
<div class="Ji-row">
        <div class="Ji-col">
            <div class="vip-login-tip" style="background-image: url(此处填写图片url);">

                <div class="vip-login-title">此处填写活动标题</div>
                <div class="vip-login-subtitle">此处填写活动介绍</div>

放在footer.php文件里，或者放在你主题自定义底部html代码中也行，只要可以加载就行！

接下来就是我改过的代码,增加了用户关闭弹窗后当天不再弹出，第二天才会弹出，或手动清除cookies，也可以
