title: Twitter Bootstrap Carousel - access current index
body: <p>How do I get the current index from the carousel?</p>
  
  <p>In this case I am using an unordered list. I know I could search through the list items to find the one with the 'active' CSS class, but I want to know if I can ask the carousel object directly.</p>
  
  <p>Additional: being able to access the target index (on 'slide' event) would be handy also. Again, I can do this by searching with:</p>
  
  <pre><code>var idx = $('.carousel-inner li.active').index();
  </code></pre>
  
  <p>...and then adding/subtracting based on direction, but I am hoping for something cleaner.</p>
