Javascript Can'；t在隐藏/显示功能中传递目标ID

我在每一篇产品文章上都有一个“阅读更多关于供应商的信息”。当你点击它时，它会弹出一个小框，里面有关于供应商的信息

代码正在运行，但当您单击文本时，它只会切换页面顶部的productarticle。看起来它不能把他们分开，给他们每个人一个唯一的ID。我不知道怎么做，因为我是一个业余爱好者。需要帮忙吗

HTML:

回路包括所有产品：

<?php  $hr='';?>
<div class="row">
    <ul class="listProductItems clearfix">
        <?php  for ($art=0; $art<count($articles); $art++){ ?>
        <?php  $imagine     =$this->site_model->show_thumbs($articles[$art]['LA_ART_ID']); ?>
        <?php  $supplier        =(($articles[$art]['producer']!==NULL) ? $articles[$art]['producer'] : $articles[$art]['SUP_BRAND']); ?>
        <?php  //$criteria      =$this->site_model->article_criteria($articles[$art]['LA_ART_ID'],$articles[$art]['ga_id']); ?>
        <?php  $criteria        =$this->site_model->article_criteria_filter($articles[$art]['la_id']); ?>
        <?php  $criteria        .=$this->site_model->article_criteria($articles[$art]['LA_ART_ID'],$articles[$art]['ga_id']); ?>






        <?php  if ($hr !== $articles[$art]['generic_name'].' PRODUCED BY '.$supplier){ ?> 

            <div class="clearfix"></div>
            <?php  $hr = $articles[$art]['generic_name'].' PRODUCED BY '.$supplier; ?> 
        <?php  } ?>




        <li class="clearfix">
            <div class="span4" style="max-height:50px">
                <?php  if (isset($imagine)){ ?>

                <div class="thumbnail"><a href="<?php  echo site_url('type/'.$versiune.'/category/'.$tree.'/article/'.$articles[$art]['la_id']); ?>"><?php  echo $imagine; ?></a></div>
                <?php  } else { ?> 
                    <div class="thumbnail"><a href="<?php  echo site_url('type/'.$versiune.'/category/'.$tree.'/article/'.$articles[$art]['la_id']); ?>">

请展示完整的代码好吗？整个.php文件有650行。我能提供更多的信息吗？我说的是，如果有显示所有内容的循环，那么现在也包括该循环。我不知道这是否有用
function myFunction1() {
var popup = document.getElementById("myPopup");
popup.classList.toggle("show");
}

        <?php  $supplier        =(($articles[$art]['producer']!==NULL) ? $articles[$art]['producer'] : $articles[$art]['SUP_BRAND']); ?>
        <?php  //$criteria      =$this->site_model->article_criteria($articles[$art]['LA_ART_ID'],$articles[$art]['ga_id']); ?>
        <?php  $criteria        =$this->site_model->article_criteria_filter($articles[$art]['la_id']); ?>
        <?php  $criteria        .=$this->site_model->article_criteria($articles[$art]['LA_ART_ID'],$articles[$art]['ga_id']); ?>
