How can I simplify form validation?

Question

The code below seems to work pretty well for doing basic required form validation.

The form displays a red Name is required message when the field is dirty

One way you could do it is to abstract your validation expression to scope methods:

PLUNKER

HTML

  Name:
  
  Name is required
  Great!

Controller

function Ctrl($scope) {
  $scope.isInvalid = function(field){
    return $scope.myForm[field].$invalid && $scope.myForm[field].$dirty;
  };

  $scope.isValid = function(field){
    return $scope.myForm[field].$valid && $scope.myForm[field].$dirty;
  };

}
