New With Javascript: Who Like To Help Me With A Loop Function?

I'm working on a script(for giving points to a soccergame 0, 1 or 3 points)
that give a value to a hidden field, i got a function but only works on 1
field.

I want that the function loops till all hidden fields are fill in.

Here's what i got so far:

function myfunction()
{

if (document.form1.hgoals.value == document.form1.agoals.value){
document.form1.hpoints.value = (1)
document.form1.apoints.value = (1)
}
else if(document.form1.hgoals.value > document.form1.agoals.value){
document.form1.hpoints.value = (3)
document.form1.apoints.value = (0)
}
else if(document.form1.hgoals.value < document.form1.agoals.value){
document.form1.hpoints.value = (0)
document.form1.apoints.value = (3)
}
