title: How to change fragment from component
body: <p>I would like to change fragment of the url programatically from the component but I'm failing to do so.</p>
  
  <pre><code>&lt;a #linkComponent routerLink='home' fragment='part'&gt;link&lt;/a&gt;
  
  @ViewChild('linkComponent') linkComponent;
  
  this.linkComponent.????
  </code></pre>
  
  <p>Or maybe there is a different way maybe using <a href="https://angular.io/docs/ts/latest/api/router/index/Router-class.html" rel="nofollow noreferrer" title="Router">Router</a></p>
