我正在使用“ DW Notifications”插件，以便在发布新帖子时收到通知警报，一切正常。
我面临的唯一问题是，如果我还没有单击按钮，而是刷新了页面，则通知计数消失了！！
所以，如何使通知计数始终显示到每个用户单击按钮之前！
notification-alert.php
<div id="dw-notifications" class="dw-notifications <?php echo '_'.$id;?>" data-id="<?php echo $id;?>">
<button class="dw-notification-btn <?php echo (isset($count_unchecked) && $count_unchecked>0)? 'has-notification' : ''?>" type="button" title="Notifications">
<i class="fa fa-bell"></i>
<span class="notif-count-unchecked"><?php echo (isset($count_unchecked) && $count_unchecked>0)? $count_unchecked : '0'?></span>
</button>
<div class="notification-group">
<div class="clearfix noti-headertop">
<div class="text-left">
<h3 class="noti-headertitle"><?php _e( 'Notifications', 'dw-notifications' );?></h3>
<div class="noti-headeraction">
<button type="button" class="dw-notif-mark-all-read" ><?php _e( 'Mask all as read', 'dw-notifications' );?></button>
</div>
</div>
</div>
<ul class="list-notification noti-body">
<?php include dwnotif_load_template( 'notification-list', false );?>
</ul>
</div>
</div>
这是JavaScript。
