如何在RAILS上发出异步GET请求并仅获取视图表单（而不是整个正文和标头）

Question

I created a simple asynchronous jquery function on my rails app so I can print the response on a "display" div. 我在rails应用程序上创建了一个简单的异步jquery函数，因此可以在“ display” div上打印响应。 But when I make the GET request to my rails url it responds the whole html: "body", "head" and "includes" as if it were a new page on a browser, so the resulting source is the following: 但是，当我向rails URL发出GET请求时，它会响应整个html：“ body”，“ head”和“ includes”，就好像它是浏览器上的新页面一样，因此，结果如下：

Before I push the button: 在按下按钮之前：

<html>
  <head>
    <title>Myapp1</title>
  </head>
  <body>
      <button onclick="callPage()">Call</button>
      <div id="display"></div>
  </body>
<html>

After I push the button and the "display" div is filled with my response: 在按下按钮后，“ display” div充满了我的响应：

<html>
      <head>
        <title>Myapp1</title>

      </head>
      <body>
          <button onclick="callPage()">Call</button>
          <div id="display">
             *<html>
               <head>
                 <title>Myapp1</title>
               </head>
               <body>
                 -----Content of page user/1 which is the only thing I want to get.------
               </body>
             <html>*
          </div>
      </body>

My route to users on routes.rb (RUBY ON RAILS) working fine 我在route.rb（RUBY ON RAILS）上通往用户的路线正常

  resources :users
  #get 'welcome/index'
  match ':controller(/:action(/:id))', :via => :get

My Jquery GET callPage (working fine) 我的jQuery GET callPage（工作正常）

<script>
         function callPage()
    {   
        url="user/1";
        div="display";
        $.ajax({
            type: "GET",
            dataType: "text",
            url: url,
            success: function(msg){
                if(parseInt(msg)!=0)
                {
                    $("#"+div).html(msg);
                }
            }   
        }).setRequestHeader('X-CSRF-Token', AUTH_TOKEN);
    }
        </script>

The question is how do I prevent RAILS from printing out every html tag all over (body, heads,...) and get it to print only the view of the controller I want (in this case, users). 问题是如何防止RAILS将所有html标记全部打印出来（身体，头部等），并使其仅打印我想要的控制器（在这种情况下为用户）的视图。 ¿Is it a configuration somewhere or do I wave to trim this off somehow? ¿它是某处的配置吗？还是我想以某种方式调整它？

Thanks a million in advance for your time. 预先感谢您花费一百万美元。

To only display the view you have to change your controller action to have render layout: false at the end. 要仅显示视图，您必须将控制器操作更改为具有渲染布局：最后为false。 This will prevent the layout from rendering, leaving only the content in your view file. 这将阻止呈现布局，仅将内容保留在视图文件中。

For example: 例如：

class YourController < ApplicationController
  def show
    # bla bla
    render 'your_show_view_name', layout: false
  end
end

If you want all your controller actions to have this behavior you can put it right at the top 如果您希望所有控制器动作都具有此行为，则可以将其放在顶部

class YourController < ApplicationController
  layout false
  def show
    # bla bla
  end
end
