请解释如下代码为什么不能通过，onclick和onserverclick
我希望，首次加载时出现first load，点击按钮后出现clientclick，second load，serverclick
<script language=javascript>
function aaa()
{
alert( "clientclick ");
return true;
}
</script>
<script language=cs runat=server>
void Page_Load(Object Sender,EventArgs e)
{
if(!IsPostBack)
Response.Write( "first load ");
else
Response.Write( "second load ");
}
void bbb(Object Sender,EventArgs e)
{
Response.Write( "serverclick ");
}
</script>
<body >
<form id= "form1 " runat=server>
<input type=button id=btn1 onclick= "aaa() " onserverclick= "bbb() " runat=server NAME= "btn1 "/>
</form>
</body>
[解决办法]
不能降紫写，如果即要执行JS，又要执行CS，则需要在PAGE_LOAD中加入
btn1.Attributes.Add( "onclick ", "aaa() ");
