title: How to get actual value from array filtered in angularJS
body: <p>My problem is that I need to know when my array filtered is empty. I'm applying some filters to an array and showing the results, when the filters make no results, I need to show a message error. How can I catch the moment when the array is empty ? </p>
  
  <p>Html: </p>
  
  <pre><code>&lt;div ng-repeat="array in arrays | filterArray1 | filterArray2 | filterArray3 | filter: 'name'&gt;
  </code></pre>
  
  <p>Thanks in advance.</p>
