Munchkin Limitation from Seeing Entire Webpage?

Yes, when you use an infinite scroll effect with lazy loading, Munchkin doesn't know about the links that are added after initialization (init()).

Fix that by running this code once at the start (to mark off the initial set of natively-detected links) and then run it again every time there's a scroll event.

function refreshMunchkinLinks(native) { 
 var arrayFrom = Function.prototype.call.bind(Array.prototype.slice); 
 var visitedAttr = ["data-munchkin-visited","true"],
 unvisitedLinks = document.querySelectorAll('A:not(['+ visitedAttr.join('=') + '])');
 arrayFrom(unvisitedLinks) 
 .forEach(function(link){ 
   link.setAttribute.apply(link,visitedAttr); 
   if (!native) { 
     link.addEventListener("click",function(e){ 
     var youTubeId = this.getAttribute('data-youtube-id'), 
       loggedHref = youTubeId ? 'video/' + youTubeId : this.href; Munchkin. 
     munchkinFunction("clickLink", { href: loggedHref }); 
   }); 
  }
 }); 
}

So right after Munchkin.init(), run

refreshMunchkinLinks(true);

then also run

refreshMunchkinLinks(false);

inside an Infinite Scroll append listener. (I detest jQuery so that part of the code is up to your designer. )
