我有一个非常令人困惑的问题。我以前做过，但不知道为什么在这种情况下它不起作用，我会感谢任何可能知道从哪里开始寻找的人。

# app/views/petitions/new
<%= form_for @petition, :remote => true do |form| %>
  <%= form.submit "Submit", :class => "primary" %>
<% end %>


# app/controllers/petitions_controller       
def create
  # I've stripped everything out of here to isolate the issue
end

# app/views/petitions/create.js.erb
alert("Hello World");

# log

Processing by PetitionsController#create as JS
Parameters: {"utf8"=>"✓", "authenticity_token"=>"bWXmagSz0hVqhQ1/1U480kQUYcIhmSEbNMAofWYT2Oc=", "petition"=>{"name"=>"", "email"=>"", "location"=>""}, "commit"=>"Submit"}
  Rendered petitions/create.js.erb (0.0ms)
  User Load (0.3ms)  SELECT `users`.* FROM `users` WHERE `users`.`id` = 1 LIMIT 1
  SQL (0.6ms)  UPDATE `users` SET `last_activity_at` = '2012-02-03 04:07:43' WHERE `users`.`id` = 1
Completed 200 OK in 5ms (Views: 2.5ms | ActiveRecord: 0.9ms)

“alert()”永远不会触发，我在.js.erb视图中也不会执行任何其他操作，即使日志显示Rendered petitions/create.js.erb (0.0ms). 我以前在其他（非 3.2）项目中这样做过，所以我确信我正在做一些非常愚蠢的事情，或者这里发生了一些非常偷偷摸摸的事情。

更新- Firebug 似乎告诉我我收到的内容类型是“text/html”而不是“text/javascript”。我仍然不确定为什么会发生这种情况或从哪里开始寻找原因，任何提示将不胜感激。

您应该在顶部有以下行PetitionsController：

respond_to :js, :only => :create
