What is the best way to update more that 1 div in AJAX c

Hi
    In controller suppose action is replace_this then create a file
replace_this.rjs in the same folder
Now in action write
render :action => 'replace_this.rjs"

And open replace_this.rjs
page[:div1].replace_html :partial=>"partial_here"}

      Above you can use :inline, etc instead of :partial
Look
