我正在使用Active Admin将图片上传到我的应用,这很正常。但我希望上传的图像显示在Bootstrap Carrousel中。我缺乏使用Rails和Javascript的经验限制了我得到我想要的结果。
Javascript控制台会抛出此错误:
carousel.self-e47323f….js?body=1:148 Uncaught TypeError: Cannot read property 'offsetWidth' of undefined(…)
Carousel.slide @ carousel.self-e47323f….js?body=1:148

修改
我查看了可能的重复内容,我可以看到这可能是重复的,但我不确定如何将我的Ruby loop
集成到javascript
中。
有人可以告诉我。代码在
之下已修改 已更新代码

可能你会错过课程&#39;活跃的&#39;或者课程“活跃”被添加到所有项目。添加课程&#39;有效&#39;到你想先显示的照片。
下面的代码会添加“活跃”字样。到第一张图片。
<% @product.photos.each_with_index do |photo, index| %>
<div class="item #{"active" if index.zero? }">
<%= image_tag(photo.image.url(:large)) %>
</div>
<% end %>
另外,请检查您网页上的javascript错误。
