Why always UpperCase in my code?
<pre><code>&lt;script type="text/javascript" src="jquery-1.3.2.js"&gt;&lt;/script&gt;
&lt;input id=a type="text" value='sss'/&gt;
&lt;script type="text/javascript"&gt;
    $('#a').keyup(
  function(event){
   alert(String.fromCharCode(event.which))
  })
&lt;/script&gt;
</code></pre>

<p>you can test this code in your brower,</p>

<p>and it always alert UpperCase of a charcode.</p>
