How to Iterate reading numerous file-field forms ???

[HelLind]

I have more than one File field forms named filename0, filename1,
filename2, and so on.....

And then I use javascript to read the value:

document.formupload.filename0.value
document.formupload.filename1.value

But I want to iterate it in a FOR loop, to save long codes.

for (i = 0; i < 9; i++) {
document.formupload.filename(???).value
}

How do I use JS to solve the above problem, to replace the (???), to
read the values of all the forms.

This surely have been answered before, but I don't know what keywords
to google for.

So anyone can help will be appreciated. TIA

a.b is equivalent to a["b"]

document.formupload["filename" + i]

var f=9
while(f--){document.formupload["filename+i].value}
