SyntaxHighlighter与ajax联合使用遇到的问题

SyntaxHighlighter是一个代码高亮插件，cnblogs的评论也用到了SyntaxHighlighter。SyntaxHighlighter的详细介绍，园子中有很多。这里就不介绍了。

使用JQ的Ajax

说下我遇到的问题，下面是测试页面：

< script type ="text/javascript" >
SyntaxHighlighter.config.clipboardSwf = ' scripts/clipboard.swf ' ;
SyntaxHighlighter.all();
</ script >
< script type ="text/javascript" >
function load(user){
var params = ' u= ' + user;
// 1
document.getElementById( " div1 " ).innerHTML = " <preclass='brush:csharp;'>privatevoida(){}</pre> " ;
$.ajax({
type: " post " ,
url: " Ajax.aspx " ,
data:params,
success: function (msg){
// 2
document.getElementById( " div2 " ).innerHTML = " <preclass='brush:csharp;'>privatevoidb(){}</pre> " ;
}
});
return false ;
}
</ script >
</ head >
< body onload ="load('tenghoo');" >
< div id ="div1" ></ div >
< div id ="div2" ></ div >
</ body >
</ html >

下面是IE6下的显示效果：

上面用到了JQ的Ajax方法，可以看到Ajax执行成功后的赋值操作没有显示出代码高亮的效果。

//2
document.getElementById("div2").innerHTML="<preclass='brush:csharp;'>privatevoidb(){}</pre>";

手工创建XMLHttpRequest

是JQ的Ajax方法的问题吗？于是我又试了下面的方法：

}
});
return false ;
}
function load1(user){
// 1
document.getElementById( " div1 " ).innerHTML = " <preclass='brush:csharp;'>privatevoidc(){}</pre> " ;
var xh = window.XMLHttpRequest ? new XMLHttpRequest(): new ActiveXObject( " Microsoft.XMLHTTP " );
xh.open( " GET " , " Ajax.aspx?u= " + user, true );
xh.onreadystatechange = function (){
if (xh.readyState != 4 ){
return ;
}
var v = xh.responseText;
// 2
document.getElementById( " div2 " ).innerHTML = " <preclass='brush:csharp;'>privatevoidd(){}</pre> " ;
};
xh.send();
return false ;
}
</ script >

</ head >
< body onload ="load1('tenghoo');" >
< div id ="div1" ></ div >
< div id ="div2" ></ div >
</ body >
</ html >

效果没啥变化：

难道是Ajax的问题？ 请JS达人帮忙。

晕，刚上首页就被拿下了，放侯选区吧。 也不知道吉日 兄怎么拿到得免死金牌。
