title: ng-show when array length is zero
body: <p>I am a beginner for AngularJS. I am trying to display "No Tag Found" during filter process with the help of "<strong>ng-show</strong>".</p>
  
  <p><strong>JS:</strong></p>
  
  <pre><code>function simpleController($scope)
  {
  $scope.tags = ['HTML','CSS','Jquery','Bootstrap','AngularJS'];
  }
  </code></pre>
  
  <p><strong>HTML:</strong></p>
  
  <pre><code>&lt;div ng-controller="simpleController"&gt;
  &lt;input  class="txt" type="text" ng-model="nameText" /&gt; 
  &lt;div&gt;
   &lt;ul&gt;
    &lt;li ng-repeat="myKeys in tags| filter:nameText"&gt;{{myKeys}}&lt;/li&gt;
   &lt;/ul&gt;
  &lt;div ng-show="!tags.length"&gt;No Tag Found&lt;/div&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>When I type any value other than array vales, I am not able to get "No Tag Found" using the above code. Please help. Thanks.</p>
