Select input appened to page
<p>I have an input field that is appended to a div tag through a location.href reload.  How would select that input field using jQuery?  If I add it to the page it won't work, I'm assuming because the input isn't loaded into the DOM yet.  </p>

<pre><code>$('#fileName1').focus(function() {
  alert('Handler for .focus() called.');
});
</code></pre>
