Angularjs Custom Form Validation

update: 9/9/14 added the ng-learn link which has  a flushed out example. If you are doing this you will need to change you test cases and include all the things like you were testing a directive.

If you want to set an input value to be invalid before submission then this is a good resource.

$scope.yourForm.nameOfElement.$setValidity( ‘reason’,  false );

E.G.: You want to add an error to your start date in a search form.

$scope.searchForm.startDate.$setValidity( ‘date’, false );
