Thank you very much Peter.
I've inserted these code and when I open my pdf file in Acrobat

it's working, but it only tells me that:
do_digit(7) at page 0
First thing to say: I'm also a javascript beginner (used it only once!),
so don't expect too much from me :)
In the following code the missing vars and function are added
(javascript debugger), but still the initialisation ('undefined' text)
and the reset for the result field are missing (and who knows what
else). But it's a 'working' starting point.
\startJSpreamble functions used now
function do_digit(d)
{console.println(do_digit(+d+) at page +[this.pageNum]);
Stack[Level] += String(d);
do_refresh(Level) }
var Stack = new Array();
var Level = 1 ;
function do_refresh (i) { vv = this.getField(Stack..concat(i)) ;
if (vv) { vv.value = Stack[i] ;
vv.readonly = (i!=Level) ;
this.dirty = false } }
\stopJSpreamble
and the field never changes. I guess I have to specify some link
between the JavaScript variant and the ConTeXt. Can you give me just
one simplest example that shows JavaScript code
var tempstring = Yes;
in pdf file? Or you could think I'm very boring so can you just
suggest some materials that I can find these techniques?
I have not used text fields before (so no example code) and this is all
I have about JavaScript:

Re: [NTG-context] How to display JavaScript's values in ConTeXt
It's so kind of you. Your example really helps me 'cause I can learn
javascript and ConTeXt by books but there are few materials about how
to associate them.
Still, I'm sorry I have to open a new thread. I don't know how to
reply under you, it's sad.
