\setupoutput [pdftex]

\setuppapersize[S6][S6]

\setupinteraction
  [state=start,
   color=red,
   openaction=ResetForm,
   closeaction=ExitViewer]

\setupinteractionscreen
  [option=max]

\setupcolors
  [state=start]

\startJSpreamble {Initialize} used now
  function SetDate (name)
    { this.d = new Date() ;
      v = this.getField(name) ;
      if (v) { v.value = util.printd("dd. mmmm yyyy", d) } }
  SetDate ("date") ;
\stopJSpreamble

\setupfield
  [DatumSetup]
  [frame=off,width=8cm,height=4ex]

\definefield
  [date] [line] [DatumSetup]

\starttext

today is the: \lower1ex\hbox{\field[date]}

\goto{Reset}[ResetForm]

\goto{Set}[JS(SetDate{date})]

\stoptext

As you can see, context picks up the function from the preamble automatically. Saves you some typing.
