我正在尝试创建一个时间轴，用户可以在时间轴上创建事件。我以前工作得很好，但是我已经将我的Rails版本更新到3.2.14，它已经不再适用了。如果版本之间发生了某些变化，或者我做错了什么，这可能是一个语法错误吗？
时间轴显示视图呈现包括时间轴的部分，并创建/编辑/销毁事件的部分形式。据我了解，表单已提交，应该调用create.js.erb。
实际发生的是，当我点击“创建事件”时，页面的内容将被标准的“事件已成功创建”通知（不是create.js.erb中的那个）替换，而且否则就消失了。事件已经创建了。有人可以帮忙吗？
时间线显示视图：
<div id="show-timeline">
<%= render :partial => "show_timeline" %>
</div>
<div class="content-box timeline-box">
<div id="my-timeline-box">
<%= render :partial => "my_timeline" %>
</div>
<br />
<button id="new-event-button" class="btn btn-success btn-large">New Event</button>
<button id="edit-events-button" class="btn btn-info btn-large">Edit Events</button>
<button id="delete-events-button" class="btn btn-danger btn-large">Delete Events</button>
<div id="events-forms">
<div id="new-event">
<%= render :partial => "new_event", :locals => { :event => Event.new(:timeline_id=>@timeline.id) }, :remote => true %>
</div>
<div id="edit-events">
<%= render :partial => "edit_events", :locals => { :events => current_user.events }, :remote => true %>
</div>
<div id="delete_events">
<%= render :partial => "delete_events", :locals => { :events => current_user.events } %>
</div>
</div>
<div id="events-forms-edit"> </div>
</div>
事件/ create.js.erb
$('#new-event').html('<%= escape_javascript( render :partial => "/timelines/new_event", :locals => { :event => Event.new(:timeline_id=>@timeline.id) }, :remote => true ) %>');
$('.notice').html("<p>Event was successfully created.</p>");
$('.notice').show(300);
$('#my-timeline-box').html('<%= escape_javascript( render :partial => "/timelines/my_timeline" ) %>');
$('#show-timeline').html('<%= escape_javascript( render :partial => "/timelines/show_timeline" ) %>');
$('#edit-events').html('<%= escape_javascript( render :partial => "/timelines/edit_events", :locals => { :events => current_user.events }, :remote => true ) %>');
$('#delete_events').html('<%= escape_javascript( render :partial => "/timelines/delete_events", :locals => { :events => current_user.events } ) %>');
事件控制器创建动作：
def create
@event = Event.new(params[:event])
@timeline = current_user.timeline
respond_to do |format|
if @event.save
format.html { redirect_to @event.timeline, notice: 'Event was successfully created.' }
format.json { render json: @event, status: :created, location: @event }
format.js
else
format.html { render action: "new" }
format.json { render json: @event.errors, status: :unprocessable_entity }
format.js
end
end
end
非常感谢任何帮助！
更新：
_new_event.html.erb
<br />
<h2>Add an event</h2>
<h4>Fill in the form and click 'Create Event' to add a new event to the timeline.</h4>
<%= form_for(event, :remote => true) do |f| %>
<% if event.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(event.errors.count, "error") %> prohibited this event from being saved:</h2>
<ul>
<% event.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%=f.hidden_field 'timeline_id', :value => current_user.timeline.id %>
<div class="field">

<div class="field" id="media_box">
<%= f.label :media %> <span>Please paste a URL here</span><br />
<%= f.text_field :media, :size => 50 %>
</div>
<div class="field">
<%= f.label :media_description %><br />
<%= f.text_area :caption, :size => "47x3" %>
</div>
<div class="actions">
<%= f.submit 'Create Event', :class => "btn btn-success" %>
</div>
<% end %>

检查 application.js.coffee 顶部是否有以下行：
#= require jquery
#= require jquery_ujs
如果您不使用咖啡，则行应该相同，但以//=开头。
您似乎不需要Rails Unobtrusive Javascript库，因此您的表单帖子被视为HTML而不是JS。
如果确实涵盖了这种依赖关系，您是否还可以提供与此问题相关的javascript文件的代码？
