Spry Validation: Strong Password

Question

Hi Chaps,
I'm looking for a bit of Spry Script to validate a user password input on a sign_up.php script.
I can validate the input for 'No Special Characters' and the 'Number of Min/Max Characters':
<script>
function myValidation(value) {
   return /^[a-zA-Z0-9\s.\-\_]+$/.test(value);
</script>
<span id="sprytextfield1">
          <input name="password" type="password"></input>
          <span class="textfieldRequiredMsg"><br />Please enter a Password</span>
           <span class="textfieldMinCharsMsg"><br />Not enough of characters.</span>
          <span class="textfieldMaxCharsMsg"><br />Too many characters.</span>
          <span class="textfieldInvalidFormatMsg"><br />No Special Characters Allowed</span>
</span>
<script type="text/javascript">
<!--
var sprytextfield1 = new Spry.Widget.ValidationTextField("sprytextfield1", "custom", {validation: myValidation, minChars:6, maxChars:12, validateOn:["blur", "change"]});
//-->
</script>
but I'd also like to make sure the user's password contains at least 1 Capital Letter and at least 1 number.
Is there Spry validation that can do this, or can I edit myValidation()?
Many thanks

^(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{6,12}$
and remove the min and max characters from the constructor
