For example i have many comments rendered for the post.

<%= render post.comments %>

And in comments partial i have javascript wich will repeated so many times how many comments i have

_comment.html.erb

<div id="content_<%= comment.id %>"><%= comment.content %></div>
<scr​ipt>$("content_<%= comment.id %>").click(function() { a​lert(​'content of comment <%= comment.id %>'​) });</sc​ript>

    You can change the implementation to have a single js file under app/assets/javascripts with your script inside. change the selector of the script to match the class of the comments instead of a unique ID. If required, use javascript to read the content of elements, instead of doing this on the server as you do now.
