Hello all

is it possible?  
I have a select list, and “onchange” event i am using a  
remote\_function, when it is completed, I wanted to execute a  
javascript: $(this).next(.‘product\_price’).value =  
“RESPONSE\_TEXT\_FROM\_AJAX\_REQUEST”

there is some way to do this?

supply an onComplete or an onSuccess handler, eg  
:complete =\> ‘…’  
what you give will be wrapper in a function declaration where request  
will be the request that completed (and so request.responseText is  
what the server rendered).  
Just check that ‘this’ is what you think it is

An alternative to the other answer - don’t reply with raw text. Write  
your  
action like this:

def action  
result = whatever(params)  
render :update do |rjs|  
rjs.replace\_html :product\_price, convert\_to\_html(result)  
end  
end

I don’t know how convert\_to\_html will convert your result; its return  
value must  
be a string of well-formed HTML. The benefit is you do all this on the  
server  
side, so the resulting Javascript is more likely to work with more  
browsers.
