Model in a modal window in angularjs is empty

问题

Hello I am using angularjs ui bootstrap and I have one text field in a modal window, which when I try to print it in alert window it is empty. Any reasons why? Here is a plunker of the code.

Try to change the

• $scope.testField

into

• $scope.myModel.testField (or user.firstName...)

As mentioned in this video angular JS - best practice (29:19):

"Whenever you have ng-model there's gotta be a dot in there somewhere. If you don't have a dot, you're doing it wrong."

When using the modal service with ui-bootstrap, you need to encapsulate your model in a container scope, eg:

$scope.form = { testValue: '' };
