remote_function alternative in rails 3.1

问题

I'm doing a tutorial for rails animated loading page but the problem is that I get the following message undefined method `remote_function'.I've done some research and it seems that "remote_function" is deprecated.Can anyone tell me please how to I make the code work on rails 3.1 :

onload="<%= remote_function(:url => { :action => :get_content_to_display } ) %>"

Thanks for helping

Rails 3.1 prefered to use unobtrusive javascript. So you should use javascript framework (for ex. JQuery) to achieve your goal. In old version of Rails remove_function just sent AJAX request to server when it was called. So you can do something like this:

$(document).ready ()->
  $.get "your_url", ()->
    #handle response

Hope it will help you. And here is some additional info: JQuery.get()

For quick fix of using prototype function in rails 3.1, add prototype_helper in your helpers folder the remote_function will be working fine then.
