Show data after AJAX call, how to render in controller?

I would like to use link_to to call a controller action named show. This happens, I get a 200 message. Now I want to update a div with the content that is being returned.

Code in controller:

respond_to do |format|
  format.html # show.html.erb
  format.js 
 end

Code in view, link and JavaScript:

<%= link_to "Show analysis", company_comparison_path(3), :remote => true , :id => "thelink" %>

<div id="replaced"> will be replaced </div>

<script>  
$('#thelink').bind('ajax:complete', function() {  
        $('#replaced').html(data)
});  
 </script>

I think I still don't understand how to return the HTML or JavaScript from the controller properly into the JavaScript. If I replace the word "data" in the JavaScript with some text in brackets, I get proper output. But how do I get the result from the controller action?

You were almost there, but you need to tell the bound function what the actual html content is you want to insert into your #results div. When you call .html() on $('#replaced') the variable you use (data) is still undefined.

Try the following:

$('#thelink').bind('ajax:complete', function(event, data) {
  $('#replaced').html(data.responseText);
});

edit: Oh, something to keep in mind is that this may render your view including the layout which is probably not what you want. You can add something like render layout: false if request.xhr? to your controller to prevent the layout from showing up on ajax requests.

If you want to return richer content from the AJAX response, you can render the view from the controller by the :render_to_string method.

See more: http://apidock.com/rails/ActionController/Base/render_to_string

respond_to do |format|
  format.html # show.html.erb
  format.js {
    @content = render_to_string(:partial => 'some_partial_view')
  }
 end
