Angular 1.2: Is it possible to exclude an input on form dirty checking?

Question

In the example beneath, is it possible to ignore the dirty state of the dropdown list? Now it get's dirty if the user changes the selected person. But I don't care if this field is dirty in my form validation. ``` function TestingCtrl($scope) { $scope.company = ''; $scope.persons = [{ name: 'Alice' }, { name: 'Bob' }]; $scope.selectedPerson = $scope.persons[0]; $scope.checkForm = function() { if ($scope.personForm.$dirty) { alert('Form is dirty'); } else { alert('Form is clean'); } } } ``` ```

```

Accepted Answer

boindiil's directive based solution works but has a flaw: it stops working if form's `$setPritine` is executed manually. This can be solved by adding an extra line that wipes out the method behavior for the input:

```
angular.module('myApp', []).directive('ignoreDirty', [function() {
    return {
    restrict: 'A',
    require: 'ngModel',
    link: function(scope, elm, attrs, ctrl) {
      ctrl.$setPristine = function() {};
      ctrl.$pristine = false;
    }
  }
}]);
```
