Answer 1

Just use some jQuery input mask plugin, for example this http://digitalbush.com/projects/masked-input-plugin/

Then you can use:

jQuery(function($){
    $(".InputMask-cccsnn").mask("aaa 999");   
});

Answer 2

You can use try using regular expressions.

if($('input').val().match(/.{3} \d{3}$/)){
        alert('valid');
    }
    else{
        alert('invalid');
    }
