Validating that checkbox is checked.

Does anyone know how do validate that at least one checkbox out of a group of checkboxes is checked. Note: This checkboxes have the same name. I know I can give them the same name (see below) and then validate each of them. But I am processing them as a group using servlets(getParameterValues), so I would like to know if I can put them in a javascript array and then validate thet at least one is checked..
<INPUT TYPE="checkbox" NAME="daysOfWeek" VALUE="2">Monday</TD>
<INPUT TYPE="checkbox" NAME="daysOfWeek" VALUE="3">Tuesday</TD>
<INPUT TYPE="checkbox" NAME="daysOfWeek" VALUE="4">Wednesday</TD>

Thanks, Bosun

u can ref the radiogroup as an array so the fields are daysOfWeek[0]
and u can validate it as
if(document.myForm.daysOfWeek[0].checked)
u get the picture right?
