方法一：同时处理多个返回值

ListData.cs 类

using System;

using System.Collections.Generic;

using System.Web;

using System.Text;

public class ListData

{

private int pageSize;

public int PageSize

{

get { return pageSize; }

set { pageSize = value; }

}

private int records;

public int Records

{

get { return records; }

set { records = value; }

}

public ListData()

{

}

public ListData(int pageSize, int records)

{

this.PageSize = pageSize;

this.Records = records;

}

public string ToJson()

{

System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

return serializer.Serialize(this);

}

}

一般处理程序ashx:

ListData ldata = new ListData();实例化类

ldata.PageSize = pageSize;//每页显示多少条记录

ldata.Records = recount;//总记录数

context.Response.Write(ldata.ToJson());//输出到页面

页面接收值：

$(function () {

var title = $("#Info_title").text(); //评论主题

var url = '<wtl:system type="Systempath"></wtl:system>sitecn/conmmentOn/ConmmentOnListPage.ashx';//链接地址：一般处理程序地址

var date = { ctent: "0", pageTopic: "page_indexs",title:title };

$.post(url, date, function (getdata) {

var tip = eval("(" + getdata + ")");

$("#page_count").html("" + tip.Records + "");//总条数

$("#page_Size").html("" + tip.PageSize + ""); //每页显示几条

});

});

方法二：处理单个值的处理

前端：

<script type="text/javascript">

function GetPrice(p) {

$(function () {

var url = '{$syspath}Ajax/handler.ashx';

var date = { price: p };

$.post(url, date, function (getdata) {

if (getdata > 0) {

$("#discount_onclick").hide();//隐藏

$("#discount_price").text(getdata);//得到值

}

});

});

}

$(function () {

var url = '{$syspath}Ajax/Discount.ashx';

var date = { state: "0" };

$.post(url, date, function (getdata) {

$("#id_discount").text(getdata);//得到值

});

});

</script>

一般处理程序：

<%@ WebHandler Language="C#" Class="Discount" %>

using System;

using System.Web;

using System.Data;

public class Discount : IHttpHandler {

public void ProcessRequest (HttpContext context) {

context.Response.ContentType = "text/plain";

try

{

string result = string.Empty;

//string option1 = string.Empty;

DataTable dt = (Whir.Repository.DbHelper.CurrentDb.Query("select top 1 * from dbo.Whir_Mem_Member where loginName=@0 and isdel=0",new FrontBasePage().GetUserName())).Tables[0];

if (dt != null && dt.Rows.Count > 0)

{

foreach (DataRow dr in dt.Rows)

{

if (!string.IsNullOrEmpty(dr["discount"].ToString()))

{

result = dr["discount"].ToString();

}

}

}

context.Response.Write(result);

}

catch (Exception ex) { }

}

public bool IsReusable {

get {

return false;

}

}

}
