我想用PhotoSwipe構建一些簡單的照片庫：http://codepen.io/dimsemenov/pen/ZYbPJM。當我添加新的HTML標記時javascript不能正常工作
所有代碼都可以正常工作，但是當我嘗試添加新的HTML時，像Previous/Next按鈕這樣的函數不起作用。
原始代碼
<div class="my-gallery" itemscope itemtype="http://schema.org/ImageGallery">
<figure itemprop="associatedMedia" itemscope itemtype="http://schema.org/ImageObject">
<a href="https://farm3.staticflickr.com/2567/5697107145_a4c2eaa0cd_o.jpg" itemprop="contentUrl" data-size="1024x1024">
<img src="https://farm3.staticflickr.com/2567/5697107145_3c27ff3cd1_m.jpg" itemprop="thumbnail" alt="Image description" />
</a>
<figcaption itemprop="caption description">Image caption 1</figcaption>
</figure>
<figure itemprop="associatedMedia" itemscope itemtype="http://schema.org/ImageObject">
<a href="https://farm2.staticflickr.com/1043/5186867718_06b2e9e551_b.jpg" itemprop="contentUrl" data-size="964x1024">
<img src="https://farm2.staticflickr.com/1043/5186867718_06b2e9e551_m.jpg" itemprop="thumbnail" alt="Image description" />
</a>
<figcaption itemprop="caption description">Image caption 2</figcaption>
</figure>
而且從我的照片庫
<div class="my-gallery" itemscope itemtype="http://schema.org/ImageGallery">
<div class="col-sm-3 col-md-2 thumb-container" data-image="o3gx9ze57" data-hotlink="9x16er3a7" data-sid="s25">
<div class="thumb">
<figure itemprop="associatedMedia" itemscope itemtype="http://schema.org/ImageObject">
<a href="https://farm3.staticflickr.com/2567/5697107145_a4c2eaa0cd_o.jpg" itemprop="contentUrl" data-size="1024x1024">
<img src="https://farm3.staticflickr.com/2567/5697107145_3c27ff3cd1_m.jpg" itemprop="thumbnail" alt="Image description" />
</a>
<figcaption itemprop="caption description">Image caption 1</figcaption>
</figure>
</div>
</div>
<div class="col-sm-3 col-md-2 thumb-container" data-image="o3gx9ze57" data-hotlink="9x16er3a7" data-sid="s25">
<div class="thumb">
<figure itemprop="associatedMedia" itemscope itemtype="http://schema.org/ImageObject">
<a href="https://farm2.staticflickr.com/1043/5186867718_06b2e9e551_b.jpg" itemprop="contentUrl" data-size="964x1024">
<img src="https://farm2.staticflickr.com/1043/5186867718_06b2e9e551_m.jpg" itemprop="thumbnail" alt="Image description" />
</a>
<figcaption itemprop="caption description">Image caption 2</figcaption>
</figure>
</div>
</div>
</div>
我知道這個代碼，這個問題是從我JavaSrcipt代碼，但我不知道解決它。

如何解決這個問題？
