Check all checkboxes ... not working perfectly

Last Modified: 2012-08-16
The below code works ... but not all that well. If no checkboxes are checked it will check them all. However, if at least one is checked it will not check the others.

<!-- Begin
function isChecked(chks)
      var rval = false;
      for(var i=0; i<chks.length; i++)
                  rval = true;
      return rval;

function SelAll(field){
if (!isChecked(document.formPageEditor["Chk_IncYr"]))
		for (i = 0; i < field.length; i++)
		field[i].checked = true ;
document.getElementById("AllChecked").checked = true;
//  End -->
