Rails - Jul 2011 - help on rails 3.0.9 jquery ajax render html

HI
   I have a  .js.erb file, like:

(1) $(''#ajax-content'').html(" here to beigin <br/>
")
(2) $(''#ajax-content'').append("
  <%= escape_javascript(
               render :partial => ''ajaxnewmsg'', :locals
=>
{ :privatemsg => @privatemsg }
      ).html_safe
  %>
")
(3) $(''#ajax-content'').append(" yes finished!")

if without (2) , (1),(3) can show the on the web page with firefox.
But if there is (2),   nothing will show on the ajax-content. I
attached the ajax response from firebug at the end.  ( anything wrong
with that response?)

The question is: what is the best practice to show the complicated
html ( render result)  in .js.erb template?  (        render :partial
=> ''ajaxnewmsg'', :locals => { :privatemsg =>
@privatemsg } should be
perfect legal in rails/ruby )

why it  is not working? How could I debug it?



##the response see from firebug
$(''#ajax-content'').html(" yes I am here to beigin
<br/> ")

$(''#ajax-content'').append("<a
href=\"/privatemsgs?locale=en\">Back to
Inbox<\/a>")

$(''#ajax-content'').append("
