code:
aspx页面：
var xmlhttp;
function CreateXmlhttp() {
//在IE中创建xmlhttpRequest,适用于IE5.0以上所有版本
//根据不同的浏览器创建XMLHttpRequest

{
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
else if(window.XMLHttpRequest)
{
xmlhttp=new XMLHttpRequest();
}
}
function CallPlanPagenoDetail()
{
var dic=<%=SearchResultGrid.ClientID %>.getSelectedRows();
if(dic&&dic.length>0)
{
var pageno = dic[0].item("plan_pageno");
alert(pageno);
CreateXmlhttp();
xmlhttp.open("POST","GoodsHandler.ashx",true);//设置请求方式，请求文件，异步请求
xmlhttp.onreadystatechange = function()
{
if(xmlhttp.readystate==4)
{
//判断是否执行成功
if(xmlhttp.status==200)
{
//更新页面上的某元素
var rep = document.getElementById('divReport');
if(rep)
report.innerHTML = xmlhttp.responseText;
}
}
}
xmlhttp.setRequestHeder("Content-Type", "application/x-www-form-urlencoded;");
xmlhttp.send("action=GetPlanInDetailByPlanPageno&planPageno="+pageno):
