我正在关注Railscast #199以允许在移动浏览器中查看我的 Web 应用程序。它工作得很好,除非我尝试在移动版本中使用 UJS 在选项卡式界面中访问信息。单击选项卡在网络应用程序中有效,但在移动端我收到 406 错误。(我在 Safari 中将用户代理设置为 iPhone 后尝试了此操作。我还在 iOS 模拟器和我的 iPhone 上进行了测试。时间都没有加载任何东西。)
下面是其中一个选项卡的一些代码。谁能帮我定位正在发生的事情?这是我的代码。
这是 profile_about 中的操作profiles_controller.rb
:
def profile_about
@profile = Profile.find(params[:id])
respond_to do |format|
format.js { render :layout => nil }
end
end
在我的profiles/show.mobile.erb
(这与中的代码完全相同profiles/show.html.erb
):
<div id="tabs">
<ul id="infoContainer">
<li><%= link_to "Cred", profile_cred_profile_path, :class=> 'active', :remote => true %></li>
<li><%= link_to "About", profile_about_profile_path, :class=> 'inactive', :remote => true %></li>
</ul>
<div id="tabs-1">
<%= render :partial => 'profile_cred' %>
</div>
</div><!-- end tabs -->
(注意:我有一个profiles/_profile_about.html.erb
和的文件profiles/_profile_about.mobile.erb
。)
这是我的profiles/profile_about.js.erb
:
$("#tabs-1").html("<%= escape_javascript(render(:partial => 'profile_about'))%>");
