title: How to get validation error value(=inputed value, but not in model) angularjs way
body: <p>I’m trying to get user.name.length value at error message.
  If jQuery is used, it is realizable, but isn't there any method unique to Angularjs?</p>
  
  <pre><code>&lt;form novalidate name="myForm" ng-submit="addUser()"&gt;
  &lt;p&gt;Name:
  &lt;input type="text" name="name" ng-model="user.name" required ng-minlength="5" ng-maxlength="8"&gt;
  &lt;span ng-show="myForm.name.$error.minlength"&gt;{{user.name.length}} too short!&lt;/span&gt;
  </code></pre>
