Is there a way to off a jquery event then on it again?
<p>I've added an event listener like this:</p>

<pre><code>$('body').on('mouseenter','.classname',function() { /* code */ });
</code></pre>

<p>Then I've removed it like this:</p>

<pre><code>$('.classname').off('mouseenter');
</code></pre>

<p>Now I'd like to turn it on again. I've tried this:</p>

<pre><code>$('.classname').on('mouseenter');
</code></pre>

<p>...but it didn't work.</p>

<p><strong>How can I do it?</strong></p>
