<p>This method is a shortcut for <code>.bind('focusin', handler)</code>.</p>
<p>The <code>focusin</code> event is sent to an element when it, or any element inside of it, gains focus. This is distinct from the <a href="/focus">focus</a> event in that it supports detecting the focus event on parent elements (in other words, it supports event bubbling).</p>
<p>This event will likely be used together with the <a href="/focusout">focusout</a> event.</p>
</div>
<h3>Example:</h3>
<div class="entry-examples" id="entry-examples"><div id="example-0">
<h4><span class="desc">Watch for a focus to occur within the paragraphs on the page.</span></h4>
<pre class="prettyprint"><code class="example demo-code"><!DOCTYPE html>
