Rails - Apr 2006 - ajax question, not so basic I guess...

Hey

Is there a ajax method that triggers when the page is fully loaded?

I want to be able to specify which div to update, something like this:

<%= on_page_loaded(
                   :update => "generatedimage",
                   :url => { :action => :generateimage })
%>

What I''m trying to do is load a page with a animated gif image saying 
"custom graphics is being generated...". When this page has finished 
loading, I want to call a remote method that generates a custom image 
and returns it, replacing the first image. The generation of the custom 
image takes a few seconds, thats why I want to display the first 
animated gif.
(I want the replacement of the image to be done using ajax)

Can this be done?

Thank you guys for this awesome forum :)

I guess a call to window.onload from javascript may solve your problem.

Is it really possible to call a remote method from a javascript?
Can anybody point me in the right direction?

This cant be that hard... how do you usually solve these kind of 
problems?

Ok, i take it ajax cant do the magic for me...

I think I''ll go with a pure javascript solution like this

That would be the point :-)

window.onload=function(){
<%= remote_function(:update => ''generatedimage'',
   :url => {:action => ''generateimage''}) %>;
};

Something like that, anyway...
