invoke a controller def from view without clicking any link

Hi
   I have a controller def like

def graph_render
    get_flash_chat_objects
      respond_to do |format|
        format.js do
          render :update do |page|
            page[:graph_div].replace_html :partial => "summary_graph"
          end
      end
    end
end

    So clearly this just accept an ajax request and do the above action
This is working But what I would like to know how can I invoke it from
view without clicking a link or like that

Thanks in advance

Well unless you have a javascript timer on the page that fires off
your ajax request, it's going to have to happen in response to some
event (not necessarily a mouse click, could be page load, mouseover,
keydown etc...)

Use prototype functions to handle the onload events. It is better
than plugging in onload code into your HTML tags. Look at the online
documentation for examples. You can use either the dom:loaded event
or the window:onload event.
