我有困难的时候试图让我的部分刷新按钮preSS。我想简单地刷新分区，而不是整个页面。下面是我的看法：

 ＆LT; D​​IV ID =AJAX＆GT;
  ＆LT;％=渲染布局/逼供％＆GT;
＆LT; / DIV＆GT;
 

然后在我的部分 _confessions.html.erb ，我有一些基本的HTML和两个按钮类似于此：

 ＆LT;％=的form_tag（{：控制器=＆GT;：招供，：动作=＆GT;：upvote，：ID =＆GT; conf.id}，{：方法=＆GT ;：放}）办％GT;
    ＆LT;％= submit_tag'像'％＆GT;
＆LT;％结束％GT;
 

我的confessions_controller.rb：

 高清upvote
  @confession = Confession.find（PARAMS [：ID]）
  Confession.increment_counter：upvotes，@confession
  respond_to代码做|格式|
    format.js
  结束
结束
 

最后， upvote.js.erb ：

  $（'＃阿贾克斯）HTML（＆LT;％= escape_javascript（渲染（：部分=＆GT;'招供'））html_safe％＆gt;中）;
 

提交到我的数据库的操作工作，但页面现在重定向到 / upvote？ID = 9 （ID可以不同），而不是只刷新股利。我究竟做错了什么？我是新来的Rails，所以我可能失去了一些东西完全明显...

编辑：这是我的文件夹结构：

我的看法：意见/页/ home.html.erb

我的部分：意见/布局/ _confessions.html.erb

我的控制器：控制器/ confessions_controller.rb

我的js.erb文件：意见/口供/ upvote.js.erb

在耙路线

 供词GET /confessions(.:format）告白＃指数
                POST /confessions(.:format）告白＃创建
new_confession GET /confessions/new(.:format）告白＃新
edit_confession GET /confessions/:id/edit(.:format）告白＃编辑
 忏悔GET /confessions/:id(.:format）告白＃秀
                PUT /confessions/:id(.:format）告白＃更新
                DELETE /confessions/:id(.:format）告白＃销毁
     upvote /upvote(.:format）告白＃upvote
   downvote /downvote(.:format）告白＃downvote
       根/页＃回家
 

解决方案

请确保你有这样的你的application.js

  // =需要的jQuery
// =需要jquery_ujs
 

供参考：Rails的form_for：远程=＆GT;真不调用JS方法

然后，改变这种情况，

  $（'＃阿贾克斯）HTML（＆LT;％= escape_javascript（渲染（：部分=＆GT;'招供'））html_safe％＆gt;中）;
 

要：

  $（'＃阿贾克斯）HTML（＆LT;％= escape_javascript（渲染（：部分=＆GT;布局/供词））html_safe％＆gt;中） ;
 

I am having a difficult time trying to get my partial to refresh on button press. I want to simply refresh the div, and not the whole page. Here is what I have in the view:

<div id="ajax">
  <%= render 'layouts/confessions' %>
</div>

Then in my partial _confessions.html.erb, I have some basic html and two buttons similar to this:

<%= form_tag( { :controller => :confessions, :action => :upvote, :id => conf.id }, { :method => :put } ) do %>
    <%= submit_tag 'Like' %>
<% end %>

My confessions_controller.rb:

def upvote
  @confession = Confession.find(params[:id])    
  Confession.increment_counter :upvotes, @confession
  respond_to do |format|
    format.js
  end
end

And finally, upvote.js.erb:

$('#ajax').html("<%= escape_javascript(render(:partial => 'confessions')).html_safe %>");

The action of submitting to my database is working, but the page is now redirecting to /upvote?id=9 (id can be different), instead of just refreshing the div. What am I doing wrong? I am new to Rails, so I could be missing something completely obvious...

EDIT: Here is my folder structure:

My view: views/pages/home.html.erb

My partial: views/layouts/_confessions.html.erb

My Controller: controllers/confessions_controller.rb

My js.erb file: views/confessions/upvote.js.erb

After rake routes

    confessions GET    /confessions(.:format)            confessions#index
                POST   /confessions(.:format)            confessions#create
new_confession  GET    /confessions/new(.:format)        confessions#new
edit_confession GET    /confessions/:id/edit(.:format)   confessions#edit
 confession     GET    /confessions/:id(.:format)        confessions#show
                PUT    /confessions/:id(.:format)        confessions#update
                DELETE /confessions/:id(.:format)        confessions#destroy
     upvote            /upvote(.:format)                 confessions#upvote
   downvote            /downvote(.:format)               confessions#downvote
       root            /                                 pages#home

Make sure you have this in your application.js

//= require jquery
//= require jquery_ujs

FYI: Rails form_for :remote=>true is not calling js method

Then, change this,

$('#ajax').html("<%= escape_javascript(render(:partial => 'confessions')).html_safe %>");

To:

$('#ajax').html("<%= escape_javascript(render(:partial => 'layouts/confessions')).html_safe %>");
