title: Validate multiple email addresses in single field
body: <p>Is there a way to validate one or multiple email addresses in a single input field?</p>
  
  <p>The way that I'm currently exploring is by creating a custom directive that will split the input into different emails if a comma is detected. This is what I have so far:</p>
  
  <pre><code>angular.module('myApp')
    .directive('multipleEmails', function () {
      return {
        require: 'ngModel',
        link: function(scope, element, attrs, ctrl) {
          ctrl.$parsers.unshift(function(viewValue) {
  
            var emails = viewValue.split(',');
            // loop that checks every email, returns undefined if one of them fails.
          });
        }
      };
    });
  </code></pre>
  
  <p>The issue that I have with this is that I have been unable to call the angular email validator manually. </p>

  <p><strong>Edit 2: Turns out that I can use angular 1.3</strong></p>
