I think it is a silly way to enter a date,
but the programming is simple for someone
with an extensive experience in c++, etc.

A minimalistic example, 
without your tab function,
automatic focus is here the body,
[chrome and ie tested]:

==========================
<body onkeyup='getKey(event)'>

[<span id=a>20120307</span><span 
id=b style='color:red;'></span>]
<br><br>re-initialize by pressing 'i'.

<script type='text/javascript'>
var s = '';
function getKey(e) {
  var charCode = (e.which) ? e.which : e.keyCode
  if (charCode==73) s = '';
  if (charCode>47 && charCode<58) s += charCode-48;
  if (charCode>95 && charCode<106) s += charCode-96;
  if (s.length<9) {
    document.getElementById('a').innerHTML = 
       '20120307'.substr(0,8-s.length);
    document.getElementById('b').innerHTML = s;
  };
};
</script>
