最近使用脚本框架motors做网站，以下是处理异步更新的代码：
如果没有下载该框架可以到http://www.mootools.net/下载
JS1：
<script type="text/javascript">
window.addEvent("domready",function(){
$("send").addEvent("click",function(){
var url="broadcastmore.aspx?areaid="+$("areaidvalue").value+"&say="+escape($("say").value);
// escape()是处理编码函数，没有它传替中文时会出乱码
new Ajax(url,{method:'post',onComplete:function(){
$("Content").innerHTML=this.response.text;
alert('发表成功！');
}}).request();
});
});
</script>
HTML1：
<div class="main_zh">
<div id="Content">
</div>
<div class="mk">
<div class="titlezb">
<div class="titleleft">
<span class="text">发表评论:</span></div>
</div>
<div class="mkcontentzb" style="clear: both;">
<ul>
<li>发表评论:<br>
<textarea class="ins" id="say" name="say" rows="5" cols="50"></textarea>
<input type="submit" id="send" name="send" value="发表" />
<input id="areaidvalue" type="hidden" value="0" runat="server" /></li>
<li></li>
<li style="background-image: url(images/dot0.gif); height: 1px; background-repeat: repeat-x;">
</li>
</ul>
</div>
</div>
</div>
在.CS文件里接收参数处理完后，用
Response.Clear();
Response.Write("要更新的内容");
Response.End();
输出到页面上来。
示例二：
HTML&JAVASCRIPT:
<html xmlns="http://www.w3.org/1999/xhtml" >

return;
}
var url='Default2.aspx';
var postData=$("postMessage").toQueryString();
new Ajax(url,{method:'post',onComplete:function(){
