id selector context (v282)

Revision 282 of this benchmark created on

Description

*** This version adds a suggestion from a comment in Revision 2 of this test

Comparing the performance difference of varied jQuery 1.7 selectors.

This test page contains some dummy HTML (from html-ipsum.com) just to give the page some weight, make the selectors work a little bit.

Note that the "Tag" selector is selecting a tag that happens to be unique in the page just to be fair.

Preparation HTML

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>

<div class="container" id="containerid">
        <div class="main">
          <ul class="list-1">
            <li class="odd">item</li>
            <li>item</li>
            <li class="odd">item</li>
            <li>item</li>
            <li class="odd">item</li>
            <li>item</li>
            <li class="odd">item</li>
            <li>item</li>
          </ul>
        
          <ul class="list-2">
            <li class="odd">item</li>
            <li>item</li>
            <li class="odd">item</li>
            <li>item</li>
            <li class="odd">item</li>
            <li>item</li>
            <li class="odd">item</li>
            <li>item</li>
