jQuery plugin to allow name/value properties in "class" attribute?
<p>I have a bad cold. I was awake late last night, or sort-of awake, and I was just looking through Stackoverflow questions. I came across mention of a jQuery plugin (or maybe it was native jQuery) that allowed named properties to be coded into "class" strings and then extracted:</p>

<pre><code>&lt;span id='mySpan' class='something {toggle: checkbox2, toggleClass: hidden}'&gt;hi mom&lt;/span&gt;
</code></pre>

<p>The plugin would parse that JSON-like expression out of the "class" string.  Now that seems like some really useful functionality; in fact I have implemented a variation of that idea myself and use it heavily for driving unobtrusive behavior binding. It'd also be really nice for validation.</p>

<p>The problem is that though I've been searching for a long time this morning, I can't find anything about this plugin. It's not impossible that the whole thing was a fever-induced hallucination. Any help would be appreciated.</p>
