Count number of lowercase/uppercase/numbers in a string?

[TheFilmGod]

How do I use javascript to count the number characters/lowercase/uppercase/numbers of the string "pass"?

 

        var pass = document.basic.password.value;

$chars = # of characters
$l_let = # of lower letters
$u_let # of upper letters
$num = # of numbers

How bout this?

 

<script>
  var pass = document.basic.password.value;
  var chars = pass.length;
  var l_let = pass.match(/[a-z]/g).length;
  var u_let = pass.match(/[A-Z]/g).length;
  var num = pass.match(/\d/g).length;
  alert(
    "# Chars:   "+chars+"\n"+
    "# Lower:   "+l_let+"\n"+
    "# Upper:   "+u_let+"\n"+
    "# Numbers: "+num
  );
</script>
