I need to have this remote\_function method return more than a single  
value. Right now I have it being called when an input field blurs but I  
need it to pass more than the value for that one input field - I need it  
to pass three values. Here is what I got:

remote\_function( :update =\> ‘h\_phone’, :url =\> { :action =\>  
‘set\_h\_phone’, :id  
=\> @user.id}, :with =\> "Form.Element.serialize(‘cc2’) )

For the :with, I have tried several variations such as:  
:with =\> “Form.Element.serialize(‘cc2’),  
Form.Element.serialize(‘cc3’)”

But that doesn’t work. Is there a way to do this? Thanks in advance,

What are the values you need to pass (what are cc2, cc3 etc… ?)  
More generally what you pass to :with should be a query string, so for  
example Object.toQueryString({a: 1, b:2}) should work.  
Form.Element.serialize() does do that - it will create name=value  
pairs, but you do need to glue them together yourself.

I ended up using the :submit option. Those fields were for the three  
different parts of a phone field. Thanks for the help,
