<SCRIPT language='javascript'>
 var isfocused = null;
</script>


<FORM name='myform' action='#'>
 <INPUT type='text' name='month' size='10' maxlength='10' onFocus='isfocused=this;'>
 <INPUT type='text' name='day' size='10' maxlength='10'  onFocus='isfocused=this;'>
 <INPUT type='text' name='year' size='10' maxlength='10'  onFocus='isfocused=this;'>
</form>


now at any time you wish to know which element has focus, simply do this:

if ( isfocused )
  alert( isfocused.name );

... ok, a bad example maybe because as soon as you do the "alert" above, the focus is removed from the element and put on the alert box instead.  :>0   But the idea is the same, the "isfocused" variable will point to the form element that most recently received focus.  :)
