Question

所以我在rails中使用非常基本的ajax代码，在我的/ demo视图中我有这个

<%= form_for(:session, url: demo_sample_email_path, remote: true) do |f| %>

并重定向到此方法

def demo_sample_email
  //do stuff
  respond_to do |format|
    format.html { redirect_to demo_path }
    format.js
  end
end

根据我对Ajax的理解，/ demo页面不应该刷新，但我发现它确实如此，因为页面中的所有内容都会刷新。我插入了＆＃34; remote：true＆＃34;这应该不会让它刷新。

对于我的应用程序，我只想做一个POST表单ajax请求，它将信息发送到服务器，而不是任何回到浏览器。

Answer 1

您可以尝试render partial: "your/view", layout: false, locals: {:@foo => @bar}

如果你指示一个div来返回ajax响应，它将返回一个视图。

您还可以渲染json format.json { render :json => {:success => true, :html => (render_to_string 'your/view')} }

希望有所帮助

Answer 2

如果您的优先级为js call且 NOT HTML调用，则将其更改为..

  respond_to do |format|
    ##added .js first and then html,call will come for js,if not then html
    format.js
    format.html { redirect_to demo_path }
  end

希望它有所帮助。
