Question

我在view / users / show中有这个链接：

<%= link_to "Photos (#{@user.photos.count})", user_path(@user), id: "photo_link", remote: true %>

现在，当我点击上面的链接时，我想将[1..6]更改为[1 ..- 1]而无需在视图/ users / show中重新渲染：

<section id="photo_galery">
  <% unless @user.photos[0].nil? %>
    <% for photo in @user.photos[1..6] %>
      <%= link_to image_tag(photo.photo.url(:subprofile_thumbnail), id: "subpics"), photo.photo.url(:original), id: "subprofile_photos", class: "fancybox", rel: "gallery01" %>
    <% end %>
  <% end %>
</section>

我怎样才能做到这一点？谢谢！

您必须从控制器端进行变量更改。

控制器：

def show
  @user = current_user
  if request.xhr? 
    @photos = @user.photos[1..-1]
  else
    @photos = @user.photos[1..6]
  end 
end

查看： show.html.erb

<section id="photo_galery">
  <%= render "photos"%>
</section>
<%= link_to "Photos (#{@user.photos.count})", user_path(@user), id: "photo_link", remote: true %>

_photos.html.erb

<% unless @user.photos[0].nil? %>
    <% for photo in @photos %>
      <%= link_to image_tag(photo.photo.url(:subprofile_thumbnail), id: "subpics"), photo.photo.url(:original), id: "subprofile_photos", class: "fancybox", rel: "gallery01" %>
    <% end %>
  <% end %>

show.js.erb（如果使用jquery）

  $("#photo_galery").html("<%= escape_javascript(render(:partial => 'users/show', :object => @photos)) %>");

如果您使用原型，则必须在控制器中执行。

在link_to上单击用ajax替换节内容
