Hi RoR developers,

I have selection which is not in form object. do you have any idea how  
to assign the value of selection to variable.  
I want to write something  
var select= document.selectionid.value;

is it possible to write ?

and  
I have another question which is about params[:id] too.

is it possible call the params[:id] of selection which is not in form  
object, from controller,  
can we assign it to variable? like

@name=params[:id]

thanks for any commends
