Hi,  
I’m on Rails 1.1 and I have a problem wit RJS  
In my cotroller i have  
==\>\>\>  
def show  
@contact = Contact.find(params[:id])  
render :update do |page|  
page[:contactInfo].replace\_html :partial=\>“contactInfo”  
end  
end  
\<\<\<===

And my contactInfo partial looks like this and it’s placed inside a div  
element  
==\>\>\>

| **\<%=h @contact.first\_name%\>** &nbsp; \<%=h @contact.last\_name%\> |
| \<%=h @contact.address.address%\> | |
| Tel : \<%h= @contact.address.phone%\>&nbsp; Fax : \<%h= @contact.address.fax%\>&nbsp; E-mail : \<%h= @contact.address.email%\>&nbsp; | |

\<\<\<==

The thing is that my show method gets called and it returns a java  
script call  
$(“contactInfo”).update("

\n \n \n \n \n \n \n \n \n

| **aaa** &nbsp; aaa |
| aaa | \n |
| Tel : &nbsp;\n Fax : &nbsp;\n E-mail : &nbsp;\n | \n |

 ");

Can anyone tell me how to get my div updated ?

Thanx,  
Ovidiu

You have not specified the id element to update in replace\_html method  
(which expects an id).  
You should replace this line that way:

page.replace\_html “contactInfo”, :partial =\> “contactInfo”

</div>

Actually I have done as you suggested and the result is the same.  
page[:contactInfo].replace\_html :partial=\>“contactInfo” is also valid.

- Are you changing the Content-Type of the response? It needs to be  
‘text/javascript’ to be automatically evaluated by Prototype.

- Your div has the id ‘contactInfo’?

- Make sure you aren’t using the :update option in your remote function  
call.

- Did you run ‘rake rails:update’ to update your JavaScripts?

- Does popping an alert box work?  
page.alert(‘RJS works!’)

Cody … you’re the man:). Thanx a lot !!!  
Actualy I was having tha update option set in my remote function call  
Now it looks like this

\<%= remote\_function(:complete =\>“new Effect.Highlight(‘contactInfo’ )”,  
:url =\> { :action =\>  
‘show’,:id=\>contact.id}) %\>"

To clarify:

Make sure you aren’t overwriting the Content-Type. RJS will set it  
for you automatically.
