title: Trigger Infinite scroll at just before bottom
body: <p>So, I am using following jquery (infinite Ajax Scroll) and below is the code:  <a href="http://infiniteajaxscroll.com/docs/overview.html" rel="nofollow">http://infiniteajaxscroll.com/docs/overview.html</a></p>
  
  <pre><code>     //16.Infinite scroll
          var ias = jQuery.ias({
            container:  '#rhm_post_show',
            item:       '.rhmpsd_container',
            pagination: '#rh_nav_below',
            next:       '.rh_nav_next a'
          });
  </code></pre>
  
  <p>So, right now, it loads the next contents when the page is reached at the very bottom.</p>
  
  <p>Is there a way to trigger the load when the page is "almost" or 80% of the page height?</p>
  
  <p>Thanks!</p>
