You can try use regular expression. example: http://www.9lessons.info/2010/01/jquery-validation-with-regular.html

or setup a powerful plugin like: http://bassistance.de/jquery-plugins/jquery-plugin-validation/

Do something like this:

$(document).ready(function() {
  $("#yourInputId").keyup(function() {
     if($(this).val() == "z") {
        alert("You cant type this");
     }
  });
});
