Hello

I have a controller which executes a “render :partial” to actualise part  
of my web page (a

 object). When I do that I would like to call a  
javascript function to complete my process.  
How can I do that?  
Anyone could help me?  
Thanks  
Regards

Hello Paulo,

I’m new to RoR, but it seems to me that remote\_function() from  
ActionView::Helpers::PrototypeHelper will help you.

Well, if you want to insert some javascript in your partial, you can  
write out a tag, or (better), use the  
javascript\_tag() helper:

\<%= javascript\_tag “some\_js\_func();” %\>

That will insert a tag to call the function.

Is that what you want, or are you looking for something else?
