Hello,

I’m using RJS for AJAX call. Something like:

page[“edit\_single\_client\_div” + params[“client\_id”]].replace\_html  
:partial =\> ‘client\_single\_display’, :locals =\> {:the\_client =\>  
SmsClient.valid.find\_by\_id(params[:client\_id]), :recipients\_session\_id  
=\> params[:recipient\_session\_id]}

it works fine but sometimes the DIV doesn’t exist on the page because  
the user has paginated that piece of the page. the replace\_html displays  
Alert about that. I want to keep silent and just ignore the fact that  
the DIV doesn’t exist on page anymore.

Any ideas how to do that?

Thanks,

Tam

how about making it conditional? check existence of that div  
beforehand.
