Checking all items in a check box form

[Sillysoft]

Is there way to make it to where if someone clicks one check box the rest get checked without knowing the names of the other form names? Meaning if I load a form with a dynamic number of entries, maybe it will show 8 check boxes or perhaps 6 and I wont know the name of the form fields. So is there a way if they click one main check box the rest get checked?

Thanks

 with(document.frmChkBoxes)
   {
	 if(elements[0].checked)
	 { 
		for (i = 1; i < elements.length; i++)
		{
		  if (elements[i].type == 'checkbox')
			 elements[i].checked = true;
		}
	 }

if you want an explanation, see the 'Check them All" script/tutorial at my site (GrassBlade)
