Prefetch,prerender, preload HTML5 snippet for jQuery

intelligentPre-loading.js

  // create an object named "app" which we can define methods on
  var app = {
      // returns an array of each url to prefetch
      searchUniqueWithLimit: function(selector,limit){
          // returns an array for selector
          var hrefs = $(selector).map(function(index, domElement){
            return $(this).attr("href");
          });
          // returns the array of hrefs without duplicates
          return $.unique(hrefs).slice ( 0, limit?limit:5 );
      },

      // adds a link tag to the document head for each of prefetchLinks()
      addLinkTags: function(selector, type, limit){
          // for each searchUniqueWithLimit(jquery selector, seach limit) ...
          var self = this;
          this.searchUniqueWithLimit(selector,limit).each(function(index,Element){
              // check for array and create link element
              if ($.isArray( type )) {
                    $.map(type, function(Type, index){
                        self.addLinkToHead(Type, Element);
                    });  
              }else{
                 self.addLinkToHead(type, Element);   
              }
          });
      },
      addLinkToHead: function(type, Element){
        console.log($("<link />", {
             // with rel=type and href=Element...
            rel: type, href: Element
             // and append it to the end of the document head
        }))
        $("<link />", {
             // with rel=type and href=Element...
            rel: type, href: Element
             // and append it to the end of the document head
        }).appendTo("head");
      }
  }
  //add five pages for prefetch to head
  app.addLinkTags("a.prefetch", "prefetch");
  //prefetch google.com
  app.addLinkToHead("prefetch", "http://www.google.com");
  //prerender  first link on page with class prerender
  app.addLinkTags("a.prerender", "prerender", 1);
  //prerender google.com
  app.addLinkToHead("prerender", "http://www.google.com");
  //load first three pages in backgroud, with class preload
  app.addLinkTags("a.preload", ["prefetch","prerender"], 3);

Good work! Exactly what I was looking for
