Looping thru dynamically built checkboxes each with same name

[gulliver]

Hi,

I have a dynamically built webpage (thru ASP) which creates an indefinite number of checkboxes, each with the same name. I have a javascript function being called from the button onClick event in the form. The function is supposed to loop thru each checkbox and return false if none of them are checked. How can this be done? Do I need to use some kind of index to reference each one separately?

Thanks in advance,
Mark.

var i = 0;
var blnChecked = false;

for (i = 0; i < frm.chk.length; i++) {
	if (frm.chk[i].checked) blnChecked = true;
}

return blnChecked

just a point to bear in mind if the ASP creates only one checkbox
then it won't be an array

Thanks guys! That's cool!
