这段简单的jQuery代码错在哪？？
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script type="text/javascript" src="jquery-1.7.2.min.js"></script>
<script type="text/javascript">
function $(a){
return document.getElementById(a);
}
jQuery.noConflict();
$(function(){
$("pig").innerHTML=jQuery("ul").html();
});
</script>
<body>
<div id="pig"></div>
<ul>
<li>a</li>
<li>b</li>
<li>c</li>
</ul>
</body>
</html>
[解决办法]
jQuery(function(){
....
});
