How to cancel route change in Angular 2?
<p>I would like to cancel the route change when the user click back or forward button in the browser.
So far I manage to capture the route change event as in the code below:</p>

<pre><code>constructor(router:Router) {
  router.events
    .subscribe((event:Event) =&gt; {
      // some logic.
      // event.preventDefault(); ?
    });
}
</code></pre>

<p>I couldn't find any method / member in event to stop the event default. Then I will get this error on console because I have no route config registered as intended, this is because I use <code>location.go()</code> to modify the url.</p>

<blockquote>
  <p>Error: Uncaught (in promise): Error: Cannot match any routes: 'Some/Url'</p>
</blockquote>

<p>Is there any way to cancel the route change so Angular doesn't look at the route config?</p>
