jQuery seems to have an enable function, but not a disable function. Why?
<p>Until now I was using the following to disable/enable form fields -</p>

<pre><code>$('#fieldid').attr('disable','disable');
$('#fieldid').removeAttr('disable');
</code></pre>

<p>And that got the job done. But yesterday, I absent-mindedly typed the following to enable the field -</p>

<pre><code>$('#fieldid').enable();
</code></pre>

<p>And it worked! I silently kicked myself for not trying the the handy 'enable'/'disable' functions built into jQuery (or so I thought), and proceeded to change the line to disable to -</p>

<pre><code>$('#fieldid').disable();
</code></pre>

<p>And to my surprise, that did NOT work.</p>

<p>Am I missing something? Why is the enable() function defined but the disable() function is not? And even weirder, I could find no mention of either enable() or disable() in the jquery docs. Does anyone have any explanations?</p>

<p>I'm using jQuery 1.6.</p>
