Follow this guide:

Here is a sample jQuery code:

 //validate letter
 if ( pswd.match(/[A-z]/) ) {
     $('#letter').removeClass('invalid').addClass('valid');
} else {
     $('#letter').removeClass('valid').addClass('invalid');
}

//validate capital letter
if ( pswd.match(/[A-Z]/) ) {
    $('#capital').removeClass('invalid').addClass('valid');
} else {
    $('#capital').removeClass('valid').addClass('invalid');
}

//validate number
if ( pswd.match(/\d/) ) {
    $('#number').removeClass('invalid').addClass('valid');
} else {
    $('#number').removeClass('valid').addClass('invalid');
}

[AZ] These expressions verify that at least one letter is entered from A to Z (upper case) or through z (lower case)

[A-Z] ,
