I would like to pass the value selected in a select statement back so  
that I can use it in the controller, through using a remote\_function  
call, and I cannot figure out what I am doing wrong:

view rhtml:  
\<select id=“widgets\_id” name=“widgets[id]” onchange="\<%=  
remote\_function( :update =\> “parts”, :url=\> { :action =\> :loadParts } )  
%\>"\>  
\<%= options\_from\_collection\_for\_select @widgets, ‘id’, ‘name’ %\>

Select is built fine. I cannot find documented anywhere, where I can  
pass back the current value of the select (ie, something like "id =\>  
…)

Any help greatly appreciated. TIA

Have a look at the remote\_function() :with option.

Cheers,

This should do what you want. (I split up the remote\_function thing to  
make it easier to read in the email.)

\<% func = remote\_function(:update =\> “parts”, :url =\> {:action =\>  
:loadParts}, :with =\> “‘id=’ + escape(value)” -%\>

 \<%= options\_from\_collection\_for\_select @widgets, 'id', 'name' %\>
