仅为尚未订阅的人制作简报弹出窗口

Question

有这个网站：www.sydney-brown.com我想在其上添加一个弹出式时事通讯 - 让它正常工作，但即使在订阅之后它仍然显示。

即使我没有登录，是否可以隐藏它？

    <div class="demo"></div>

<!-- This is the modal -->
<div id="subscribe" class="subscribe uk-modal">
    <div class="uk-modal-dialog uk-text-center">
        <a class="uk-modal-close uk-close" style="color:#000;"></a>

<div class="uk-flex uk-flex-column" style="height:150px;">
    <div>        <p style="font-size: 16px; padding-top:30px;">Sign up for our newsletter<br>
        and get 15% off your first order</p>
</div>
<div class="uk-flex-item-auto"></div>
<div>

                <form action="//sydneybrown.createsend.com/t/j/s/trtkiy/" method="post" id="subForm" class="uk-form">

                <div class="control-group">
                  <div>
                  <p style="font-size: 13px;">For updates and exclusive offers:</p>
</div>
                        <input style="border: 1px solid #000;" id="email" spellcheck="false" name="cm-trtkiy-trtkiy" type="email" placeholder="enter email address" class="input-xlarge"/>
                        <button type="submit" value="Subscribe" class="subscribe-btn uk-button">SUBMIT</button>
                </div>

            <div id="response" style="color:#000;" class="uk-hidden"><br>Thanks! You're subscribed</div>
        </form>
</div>
</div>


  </div>
</div>

        });

$j(document).ready(function() {

        $j("#popup").delay(2000).fadeIn();

    $j('#popup-close, #popup').click(function(e) // You are clicking the close button
    {
        $j('#popup').fadeOut(); // Now the pop up is hiden.
    });
});

从其他人那里“获得”这个，现在必须找到我的方式。
