I’ve read an intro or two for RJS, but I don’t fully get what it may be  
used for - AJAX? Please post what you currently use RJS for.

Thanks!  
Joe

The most useful thing to me about RJS is the ability to easily update  
multiple div’s after an Ajax call. For example, in my svn management  
control panel after a new repository is added I use RJS to update the  
list of current repositories which is contained in a div. I also  
update a div that shows a box detailing how to access the created  
repository. Lastly, I hide the “Add” button if the user has reached  
his limit on the number of allowed repositories.

RJS allows me to put all these calls in a single, easy to read RJS  
file named after the ajax action that is being called. If you are  
going to use Ajax at all in your application, it is definitely worth  
learning how to use RJS.

Your best bet on documentation is to google “rails rjs template”
