title: Backbone router on every route
body: <p>My problem is:</p>
  
  <p>All the HTML is in a <code>&lt;div id="application"&gt;</code> container, which by default has <code>0</code> opacity. This is because JavaScript does some DOM positioning, so when this is all done I just add a <code>class="rendered"</code> into the <code>&lt;div id="application&gt;"</code> and then the page appears.</p>
  
  <p>So the thing is, for every route in my Backbone router, I need something that is always triggered before the actual routing, or on each route, is this possible?</p>
  
  <p>Thanks for help!</p>
