Kalkulator cen

[camelrafal]

nie wiem czy o to chodziło

Kod:

<script language="JavaScript" type="text/javascript">
window.onload = function(){
document.getElementById("przelicz").onclick = function(){
var cena = document.getElementById('produkt').value;
var ilosc = document.getElementById("ilosc").value;
document.getElementById("price_serv").getElementsByTagName("span")[0].innerHTML = Math.round(cena*ilosc)/100;
}
}
</script>
