You don't have to have them all named similarly. Nor even have all as
checkboxes.
You can refer to any form element thusly
document.formname.elements[i]
And if you wish, even check whether the form element is a checkbox
document.formname.elements[i].type == 'checkbox'
With that, as Tom says, it's easy to iterate through with the for loop.
Hope this helps.
