How to execute JS function before AJAX request using remote_form_for

Before my form initiates an AJAX request, I want to call a function.

I see that there is a convenience for link_ to_remote: before the parameter ... "Called before the request."

here is my source:

<% form_remote_for(@news, :url => {:action => 'create'}) do |f| %>

      

        
        
        
      

    

Before initiating a request, I want to call myFunction ()

Thanks for the help:)
