我前台a.aspx页面很简单，就用到了ajax帖出来，为了方便贴重哈！
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页 </title>
<script type="text/javascript">
var xmlHttp;
function createXMLHttpRequest()
{
if(window.ActiveXObject)
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
else if(window.XMLHttpRequest)
{
xmlHttp= new XMLHttpRequest();
}
}
function doing()
{
createXMLHttpRequest();
xmlHttp.open("GET","http://localhost/ajax8.aspx?date=1",true);
xmlHttp.onreadystatechange=handleStateChange;
xmlHttp.send(null);
}
function handleStateChange()
{
if(xmlHttp.readyState==4)
