<p>This plugin reformats your page to utilize <a href="http://headjs.com" title="HeadJS" rel="nofollow ugc">Head JS</a> in your WordPress site.</p>
<p><strong>Caution: this plugin can cause major issues with the javascript on your site if not implemented properly.  Please be sure to test on a development server first</strong></p>
<p>It strips out all your old javascript declarations and puts them into head.js calls so that they are loaded in parallel (see the Head JS website for more details).</p>
<p>Optionally you can wrap all your inline javascript with head.ready calls.</p>
<p>For example, this:</p>
<pre><code><script type='text/javascript' src='http://yoururl.com/wp-includes/js/prototype.js?ver=1.6.1'></script> 
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js?ver=3.0.4'></script> 
<script type='text/javascript' src='http://yoururl.com/wp-includes/js/scriptaculous/wp-scriptaculous.js?ver=1.8.3'></script> 
<script type='text/javascript' src='http://yoururl.com/wp-includes/js/scriptaculous/builder.js?ver=1.8.3'></script> 
<script type='text/javascript' src='http://yoururl.com/wp-includes/js/scriptaculous/effects.js?ver=1.8.3'></script> 
<script type='text/javascript' src='http://yoururl.com/wp-includes/js/scriptaculous/dragdrop.js?ver=1.8.3'></script> 
<script type='text/javascript' src='http://yoururl.com/wp-includes/js/scriptaculous/slider.js?ver=1.8.3'></script> 
<script type='text/javascript' src='http://yoururl.com/wp-includes/js/scriptaculous/controls.js?ver=1.8.3'></script> 
</code></pre>
<p>Becomes:</p>
<pre><code><script type="text/javascript" src="http://yoururl.com/wp-content/plugins/headjs-loader/js/head.min.js"></script> 
<script> 
head.js("http://yoururl.com/wp-includes/js/prototype.js?ver=1.6.1",
    "http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js?ver=3.0.4",
    "http://yoururl.com/wp-includes/js/scriptaculous/wp-scriptaculous.js?ver=1.8.3",
    "http://yoururl.com/wp-includes/js/scriptaculous/builder.js?ver=1.8.3",
    "http://yoururl.com/wp-includes/js/scriptaculous/effects.js?ver=1.8.3",
    "http://yoururl.com/wp-includes/js/scriptaculous/dragdrop.js?ver=1.8.3",
    "http://yoururl.com/wp-includes/js/scriptaculous/slider.js?ver=1.8.3",
    "http://yoururl.com/wp-includes/js/scriptaculous/controls.js?ver=1.8.3"
);

HeadJS Loader

A WordPress plugin to load your Javascript files via Head JS.

mneil

<p>Finds all possible .js and .css files from a WP install available and allows you to combine and/or compress the files to reduce<br />
load time. The plugin can monitor file changes in “development” mode (by hashing file mtime) which allows the plugin to<br />
recompile the files when a file changes. Or, it can cache the files in “production” mode so that files are only recompiled<br />
if they are not found or are deleted manually from the cache folder. Additionally, this plugin will allow you to force the<br />
inclusion of javascript files into either the head or the foot of the page.</p>
<p>There are two modes, development and production, the ability to force the files to print in the header or footer*, the use of<br />
Google Closure as a JS compiler, and finally the ability to pick and choose which files, including dependencies, should be combined.</p>
<p>*forcing head compiles can fail on JS files queued after the call to wp_head(). The plugin will, in this case, render the late<br />
queued files in the footer as originally intended.</p>
