弹出窗口仅在第一次点击时显示 div

Popup displays div just on first click

我正在使用 jQuery Simple Slider Plugin 在用户单击图像时显示图像的额外信息。

此插件在弹出窗口 window 中显示图像描述。效果不错。

问题

但是，我想在弹出窗口[=52​​=]中添加另一个 div，名称为 class 'like-image'。

第一次点击图片时，一切正常。 图片描述和类似图片 div 都会显示。

如果您再次点击图片之前没有重新加载页面，喜欢的图片div将不再显示。

我做错了什么？

        <div class="image-description" data-desc="Image1 Lorem Ipsum is simply dummy"></div>
        <div class="like-image"><b>This div just displays on first click.</b></div>

如有任何帮助，我将不胜感激！

用这行替换你的行

   // My attempt of adding the div to the popup window
   // The next line of code seems just to work once
   $('.product-popup-content .product-information .like-image').html($(this).find('.like-image').html());

如果您仍然发现问题，请告诉我。我在 fiddle 中查看它，它工作正常。
