Those two approaches are _not_ equivalent, and the second one would 
certainly _not_ work equally well.  We have discussed the difference between 
the value of a selected `option' and the value of a `select' so often here 
that I have lost count.

For that matter, wouldn't

  document.getElementById("stampa").onchange = function () {
    var stampa = this.value;
  };

or even

  <select name="stampa" onchange="…">
    …
  </select>

?

Answer: Nooo.  Neither wouldn't be k€wL enough!!" (far too efficient and 
compatible ;-))
