If you''re posting this to itself, and you expect the select to default,
you''re going to have to name the GET parameter exactly the same as
Rails named the select. Try changing the window.location part to
"window.location=''rnote?'' + this.name +
''='' + this.value"
You may have to fiddle with this a bit, but the basic premise is that if you
name the parameter exactly the same way that Rails would, When you come back to
the form, that select will be defaulted to match.
There is also another trick you could try, and that is the :default parameter to
the select() method. Set that to the value, so in this case, params[:vid], and
see if that does the same thing. Less changes in your code that way.
