From what I know, the $valid property (and other similar ones) are accessible with $scope.formname.inputname.$valid from the controller..
I've played around with this: http://plnkr.co/edit/oEfdMpI3URooJhRFfSUr?p=preview
this.validity = $scope.myForm.input.$valid; //ADDED THIS LINE
Why does this one line that I added in script.js break it? I would expect {{ctrl.validity}} to show up as true.
You added that line in a controller's constructor.
By the time that the constructor instance is created, the form in a view hasn't been compiled yet.
Try using $timeout
to defer the execution of the line like this to make it works:
var ctrl = this;
$timeout(function () {
ctrl.validity = $scope.myForm.input.$valid; //ADDED THIS LINE
});
Or if you want to keep them in sync, use $watch
:
$scope.$watch('myForm.input.$valid', function (isValid) {
ctrl.validity = isValid;
});
Hope this helps.
