Addressing form fields in a loop

[Andrew Banks]

I'm using the following code to fill in data in 52 form fields but I think
I've got a problem when I'm trying to concatenate my variables with the
names of form fields. Can anyone help?

var ThursArray = new
Array("01-01-04","08-01-04","15-01-04","22-01-04","29-01-04","05-02-04","12-
02-04","19-02-04","26-02-04","04-03-04","11-03-04","18-03-04","25-03-04","01
-04-04","08-04-04","15-04-04","22-04-04","29-04-04","06-05-04","13-05-04","2

","02-12-04","09-12-04","16-12-04","23-12-04","30-12-04");

function SetDates(ArrayToUse){
for (i=0; i < ArrayToUse.length; i++){
//alert(ArrayToUse);
//alert("I is " + i + " Thurs array is " + ThursArray);
document.add_record_form.date + i + .value = ArrayToUse;
}
}

Code should have line breaks at intervals, so that it can be posted in
News without corruption.

No need to list those; it is way enough to calculate all the Thursdays
in a year (and much less annoying if you find they should be Tuesdays);
see below. Test

function DoThu(Y) {
var D = new Date(Y, 0, 1).getDay() // Jan 1, Sun=0..Sat=6
for (D = new Date(Y, 0, 1 + (4+7-D)%7) ; // 4 = Thu
D.getFullYear()==Y ;
D.setDate(D.getDate()+7) ) document.writeln(D, '<br>')
}

DoThu(2004)

change the last 7 to, say, 777, and do
for (j=2000; j<2030; j++) DoThu(j)
to check the start-up logic for ample years.

Then replace the write with a suitable action.

You say 52 fields; there are 53 Thursdays next year.
