Reloading partial in an rails app

问题

I want to reload a partial every 3 seconds on a 'new'-view in my rails app.

I have this in my new.html.erb

<h1>Controller#new</h1>
This is my static content
<%= render partial: 'dynamic' %>
More Static content

How do I get this partial reloaded every 3 seconds? Do I have to use unobtrusive javascript for this? How can I achieve this through ujs?

回答1:

Put partial in div

   <div class="dynamic"><%= render partial: 'dynamic' %></div>

You can do it by using jquery like this

       $(document).ready(
         function() {
          setInterval(function() {
            $('.dynamic').load('/controller_name/action_name');
        }, 3000);
    });

Now refresh partial in controller action for load new content

         def action_name
            render :partial => "directory_name/dynamic"
         end

It will sure work.........
