why the blur() can't work?
<pre><code>      &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
    &lt;head&gt;
   &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt;
    &lt;title&gt;test&lt;/title&gt;
     &lt;script type="text/javascript" src="js/jquery.js"&gt;&lt;/script&gt;
     &lt;script type="text/javascript"&gt;
   $('#target').blur(function() {
 alert('welcome,boy.');
  })
&lt;/script&gt;
   &lt;/head&gt;

 &lt;body&gt;
  &lt;form&gt;
&lt;input id="target" type="text" value="Field 1" /&gt;
 &lt;input type="text" value="Field 2" /&gt;
  &lt;/form&gt;
 &lt;div id="other"&gt;
  Trigger the handler
&lt;/div&gt;

&lt;/body&gt;
&lt;/html&gt;
</code></pre>
