easy : form.vars.your_select_field_name
What do you need exactly, you didn't tell us... Your example is difficult
to understand (tldr)
As I wrote if you want to know what was the input select value once form is
submitted it can't be more easy...
My guess though, is that you want to create a kind tag-it behavior??
In this case for optimal performance you should look into jQuery tag-it or
other javascript plugin for that.
Or consider using ajax for input new select option.
