For IE 5 and NN 4.7 at least,
I made it work like this:
for(var i = 0;i<numrows;i++){
//alert(i);
//alert(theform["changed["+i+"]"].value);
if (theform["changed["+i+"]"].value == 'true') {
//record is changed
//alert ("FOUND CHANGES");
var FREQ = theform["FREQ["+i+"]"];
var YEAR = theform["START_YEAR["+i+"]"];
var MONTH = theform["MONTH["+i+"]"];
var LBS = theform["NO_STOCKED["+i+"]"];
var NUM = theform["LBS_STOCKED["+i+"]"];
if (theform["RATE["+i+"]"]) {
var RATE = theform["RATE["+i+"]"];
var str_RATE = theform["RATE["+i+"]"].value;
}
var str_qual = theform["QUAL["+i+"]"].value;
if(isNaN(LBS.value)) {
return warnInvalid (LBS, "LBS is not a number");
}
if (isNaN(NUM.value)) {
return warnInvalid (NUM, "NUM is not a number");
}
return checkMonth(MONTH,false);
return checkYear(YEAR,false);
} //end if changed
}
when my form fields were named like this:
<INPUT TYPE = TEXT NAME = 'RATE[<?PHP echo $row?>]'>
etc.
It works well

After several tries, I am convinced there is no way to do it. I went around
the problem by using dinamic field names (var1, var2, var3, etc) and then
reading them using $HTTP_POST_VARS["var".$i], where $i would be your former
index to the array. For example:
The form coud have HTML code like this:
<input type=text name=myvar0>
<input type=text name=myvar1>
<input type=text name=myvar2>
Each field can be referenced by JavaScript code like this:
document.myform.myvar1.value="hello";
Or dynamically like this:
myfield=new array();
for(i=0;;i++)
if(!eval("document.myform.myvar"+i)) break;
myfield[i]=eval("document.myform.myvar"+i);
}
myfield[1].value="hello";
When the form is submitted, asuming, method=POST, then you get the field
values like this:
$myvars=array();
for($i=0;;$i++)
{
if(empty($HTTP_POST_VARS["myvar".$i]) break;
$myvars[$i]=$HTTP_POST_VARS["myvar".$i];
}
Hope it helps.
Cheers, Diego.

Hello,
I see you sent this back in January. I'm having the very same problem.
Could you PLLLLEEEAAASSEEE tell me how to assign a value to the
'myfields[]' text field using JavaScript. I can't make it happen.
Thanks.

THIS WAS YOUR MESSAGE ON THE BOARD
Hi! I was wondering if someone knows, or can think of a way to go around
this problem i have.
The thing is i am working with a form with a field array. Each field is
something like:
<input name="myfields[]" type="text">
When i receive the posted data, I can access the "myfields" array. This is
fine.
The problem is within my form i have client JavaScript code to validate
the
form data. But I can't make reference to a form object called myfields[]
or
myfields[5] or just myfields. The property name of the javascript object
is
set to "myfields[]", but reference to myfields[][5] or
document.myform.fields["myfields[]"] doesn't work either.
Any suggestions will be greatly appreciated.
Thanks in advance.
