Render Template From DOM Select vs Cache vs HTML Cache (v11)

Revision 11 of this benchmark created on

Description

This test was spawned by some discussion in a StackOverflow thread:

http://stackoverflow.com/questions/9833312/how-do-i-properly-store-a-javascript-template-so-that-it-isnt-instantiated-mul

The purpose is to test the speed of rendering an underscore.js template when selecting the template from the DOM every time, vs selecting it once and re-rendering the cached template every time.

Preparation HTML

<div id='tp'>
  <p> this is <div class = "foo"> some html </div>
  </p> <ul><li> with data <li> and items <li> etc </ul>
</div>

<script id="test-template" type="text/template">
  < p > this is < div class = "foo" > some html < /div>
  </p > < ul > < li > with data < li > and items < li > etc < /ul>
</script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<script src="http://documentcloud.github.com/underscore/underscore-min.js">
</script>

<div id="html-output-goes-here">
</div>

Setup

this.cachedItem = $("#test-template");
    this.cachedHtml = this.cachedItem.html();
    this.cachedTemplate = _.template(this.cachedHtml);
    this.output = $("#html-output-goes-here");
    
    window.domout = document.getElementById('html-output-goes-here');
    window.cT = document.getElementById('tp');

Teardown


    delete this.cachedItem;
    delete this.cachedTemplate;
    window.domout.innerHTML = '';
