id selector context (v284)

Revision 284 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>
<style type="text/css">
  .hide { display: none; }
</style>
<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='even'>item</li>
            <li>item</li>
            <li class='odd'>item</li>
            <li>item</li>
            <p class='hide'>paragraph</p>
        </ul>
        <ul class='list-2'>
            <li class='odd'>item</li>
            <li>item</li>
            <li class='odd'>item</li>
            <li>item</li>
            <li class='even'>item</li>
