innerHTML vs. cloneNode (v9)

Revision 9 of this benchmark created on

Description

Tests various DOM construction patterns.

Preparation HTML

<style>
  .hidden {display: none;}
</style>
<div class="hidden"></div>
<div class="shown"></div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
  var content = '<select>';
  for (var i = 0; i < 200; i++)
    content += '<option value="'+i+'">'+i+'</option>';
  content += '</select>';
  
  var proto = document.createElement("div");
  proto.innerHTML = content;
  
  var frag = document.createDocumentFragment();
  frag.appendChild(proto.cloneNode(true));

  var $proto = $('<div>'+content+'</div>');

  var hidden = $('.hidden').get(0);
  var shown = $('.shown').get(0);

  var detached = document.createElement('div');
</script>
