form field arrays

[Hammy Hammy]

Hi all,

I have a form with many textboxes. I have named them
"txt[1]", "txt[2]", "txt[3]", etc..

I did this so that I could easily loop through them and get their
values.

However, how do I assign a value to one of these fields inside a loop?

For example:

for (i=1; i<=10; i++){
document.frmA.txt[i].value = 4
}

This gives me an error message.
I don't want to use 'document.frmA.elements[i].value because I have
other textfields on this page and the elementID doesn't always match.

thanks for any help.

Bad idea. "[" and "]" are not legal in HTML ids/names.

It would be better to call them "txt_1", "txt_2" etc.
It also prevents you from getting confuzed.
document.frmA.txt[i].value = 4

document.forms['frmA'].elements['txt_'+i].value = 4;
