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

For that matter, wouldn't
document.getElementById("stampa").onchange = function () {
var stampa = this.value;
};
or even
<select name="stampa" onchange="…">
