How do I check form validity with angularjs?

Question

I\'m very new to angularjs. Say my app has a form. Using the inspector, I noticed that if angularjs thinks that the form is invalid, it adds an ng-invalid class to the form.

When you put

tag inside you ngApp, AngularJS automatically adds form controller (actually there is a directive, called form that add nessesary behaviour). The value of the name attribute will be bound in your scope; so something like ...

will satisfy:

A form is an instance of FormController. 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.

More information you can get at Developer's Guide section about forms.
