I have a text input field for address, whenever the address is entered and search button next to the input field is clicked, I geocode the address and replace the input text with the result from the geocoder. I also set a scope variable 'addressOk'.
is it possible to invalidate this specific form input field according to $scope.addressOk or do I have to write a directive for this address geocoding input that invalidates the form when needed ?

The form instance can optionally be published into the scope using the name attribute. So to check form validity, you can check value of $scope. yourformname. $valid property of scope.
resetForm = function(){ /* reset the data to a new object so that all the properties * of form are reset */ $scope. data = {}; }; });
1) To Remove the values in Form Fields and to reset you can use $setPristine(); $scope. formName. $setPristine();
ng-controller directive tells AngularJS what controller to use with this view. AngularJS application mainly relies on controllers to control the flow of data in the application.
I found the solution, add a name attribute to the <form> and <input>, and then in the controller its possible to do $scope.formName.inputName.$setValidity(errorKey, isValid).
Then, its possible to display errors with something like ng-show="formName.inputName.$error.errorkey"
according to http://docs.angularjs.org/api/ng.directive:form If name attribute is specified, the form controller is published onto the current scope under this name.
