Hola otra vez.
No estoy seguro de haberte entendido bien, ni estoy seguro de no haberme liado mucho con el código
Pero, en fín Pilarín... Ahí va eso y tú veras si va bien la cosa:
Código HTML:
<html><head>
<script>
function sumar(num) {
elem=document.getElementById('ta').getElementsByTagName('tr')[num];
cel1=parseFloat(elem.getElementsByTagName('td')[1].childNodes[0].value);
cel2=parseFloat(elem.getElementsByTagName('td')[2].childNodes[0].value);
elem.getElementsByTagName('td')[3].childNodes[0].value=cel1 * cel2;
// Ahora vamos a sumar las columnas
var tot = new Array;
tot[1]=0; tot[2]=0; tot[3]=0;
for(i=1;i<4;i++) {
elem=document.getElementById('ta').getElementsByTagName('tr')[i];
for(j=1;j<4;j++)
tot[j]+=parseFloat(elem.getElementsByTagName('td')[j].childNodes[0].value);
}
for(i=1;i<4;i++)
document.getElementById(i).innerHTML=tot[i];
}
</script>
</head>
<body>
<form name="form" method="post" action="preview.fax.dedicated.php">
