Angular Form Validation

Form and Input States


Angular Forms and Inputs have various states that are useful when validating content

All of the above states are boolean properties and can be either true or false.

With these, it is very easy to display messages to a user.

<form name="myForm" novalidate>
 <input name="myName" ng-model="myName" required>
 <span ng-show="myForm.myName.$touched && myForm.myName.$invalid">This name is invalid</span>
</form>

Here, we are using the ng-show directive to display a message to a user if they've modified a form but it's invalid.
