AngularJS - Custom form validation

We can have some situation to use custom validations to our input fields, we can use following code to implement it.

Here my case is, I want to validate multiple emails field and have to show field error using AngularJS Form Validation.

HTML Page:

<p>Email:<br>

  <input type="email" name="email" ng-model="email" required>
  <span style="color:red" ng-show="myForm.email.$dirty && myForm.email.$invalid">
  <span ng-show="myForm.email.$error.required">Email is required.</span>
  <span ng-show="myForm.email.$error.validEmail">Invalid email address.</span>
  </span>
</p>

<p>
  <input type="button" ng-click="submit()"
  ng-disabled="myForm.email.$dirty && myForm.email.$invalid">
</p>

AngularJS Controller

$scope.Submit = function () {

     //your validation

            var isValidEmail = isValidEmailAddress($scope.email.ToAddress);

            $scope.myForm.email.$setValidity("validEmail", isValidEmail);

            var isValid = $scope.myForm.$valid;

            if (!isValid) { return; }

//your logic goes here

        };
