javascript - 仅当单击 div 的特定部分时才打开 javascript 操作

Question

我正在制作专辑页面，并且我有 this脚本将在更大的窗口中打开图像，以便我可以更好地看到它，缩放，下载等。

我对其进行了一些修改，然后我从数据库中生成了 foreach 中的图片。

         <div id="lightgallery" class="row" >

             <?php $x=1; ?>
            <?php foreach ($this->upload as $upload): ?>
            <?php $dir = Users::currentUser()->id; ?>

                          <div class="col-sm-3"  data-src="<?= PROOT . 'files' . DS . $dir  . DS . $upload->name ;?>" data-sub-html="<h4><?=$upload->name ?></h4>">

                                <div class="thumbnail text-center">
                                  <img src="<?= PROOT . 'files' . DS . $dir  . DS . $upload->name ;?>" alt="Thumb-<?=$x?>" class="imgu">

                                </div>

                                <div class="caption text-center">
                                  <hr>
                             <p><?= $upload->name;?> </p>
                                   <div class="text-center">
                                     <a href="<?=PROOT?>upload/delete/<?=$upload->id?>" class="btn btn-danger btn-xs " onclick="if(!confirm('Are you sure ?')){return false;} target='_blank' ">
                                       Delete
                                     </a>
                                   </div>
                               </div>
                          </div>
                     <?php $x++; ?>
                     <?php endforeach; ?>
                     </div>

到目前为止，我遇到的唯一问题是，我希望仅当我单击图片时才打开图片，但无论我在 div 的何处单击，它都会打开图片。即使我点击按钮Delete，它也会像脚本一样在更大的窗口中打开图片。

以及所需的 JavaScript，因为它们隐藏在 codepin.io 上

                     <script> lightGallery(document.getElementById('lightgallery')); </script>

创建灯光图库时使用选择器选项来设置打开图库的选择器，

<div class="col-sm-3">

        <div class="thumbnail text-center">
          <img src="https://dummyimage.com/300" alt="Thumb" class="imgu" data-src="https://dummyimage.com/300" data-sub-html="<h4>name </h4>">

        </div>

        <div class="caption text-center">
          <hr>
          <div>
            test div
          </div>
          <div class="text-center">
            <a href="<?=PROOT?>upload/delete/<?=$upload->id?>" class="btn btn-danger btn-xs " onclick="if(!confirm('Are you sure ?')){return false;} target='_blank' ">
                                           Delete
                                         </a>
          </div>
        </div>
      </div>

    </div>



<script>
     lightGallery(document.getElementById('lightgallery'), {
      selector: ".imgu"
     });
</script>  

在上面的代码中，我使用类“imgu”的图像作为图库的选择器，因此它仅在单击图像时打开，还为 img 标签提供 data-src 和 data-sub-html 检查下面的 fiddle https://jsfiddle.net/suhailsulu/Lya1hdtm/
