Dynamic mask based on behavior

[pedromcorreia]

Hello guys, How to create a mask based on the behavior of another field? Examples;

Field state registration can have 24 different masks based on state; If state value is 'SP' so mask should be applying as 'AAA.AAA.AAA.AAA' If state value is 'PR' so mask should be applying as 'AAA.AAA.AAA' ...

function switchVal(){
  switch($('[data-mask="state"]').val) {
    case 'SP':
      'AAA.AAA.AAA.AAA'
      break;
    case 'PR':
      'AAA.AAA.AAA.AAA'
      break;
  }
}
const behaviorState = function(val) {
    return switchVal()
    },
optionsState = {
  onKeyPress: function(val, e, field, opts) {
    field.mask(behaviorState.apply({}, arguments), opts);
  }
};
$('[data-mask="state_registration"]').mask(behaviorState, optionsState);
