1、准备：下载AjaxPro.2.dll
2、应用：项目中引用AjaxPro.2.dll
3、web.config中引用：
<system.web> <httpHandlers> <add verb="*" path="*.ashx" type="AjaxPro.AjaxHandlerFactory,AjaxPro.2"/> </httpHandlers> </system.web>
4、后台页面代码：
public partial class test2 : System.Web.UI.Page
{
protected void Page_Load(object sender,EventArgs e)
{
if (!IsPostBack)
{
}
AjaxPro.Utility.RegisterTypeForAjax(typeof(test2)); --test2为页面类名
}
//根据传递过来的商品规格获取商品信息
[AjaxPro.AjaxMethod] --声明AjaxPro
public string GetProductInfoByDetail(string guid,string detail)
{
string refs = "0";
if (detail != "")
{
string price = "";
string proNum = "";
string sql = "select * from tb1 where guid='" + guid + "' and detail='" + detail + "'";
DataTable dt = mallCtr.sqlTable(sql);
if (dt.Rows.Count > 0)
{
price = dt.Rows[0]["price"].ToString();
proNum = dt.Rows[0]["RepertoryCount"].ToString();
refs = price + "$$$" + proNum;
}
else
{
refs = "1";
}
}
return refs;
}
}
5、前台代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="test2.aspx.cs" Inherits="test2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>测试AjaxPro</title>
<script language="javascript" defer=true>
function GetProductNum()
{
refs=test2.GetProductInfoByDetail(document.getElementById("<%=TextBox1.ClientID %>").value,document.getElementById("<%=TextBox2.ClientID %>").value).value; //获取后台返回值
if (refs!="0")
{
//alert(refs);
var val=refs.split('$$$');
document.getElementById("<%=TextBox3.ClientID %>").value=val[0]; //给textBox赋值
document.getElementById("Label2").innerHTML = val[1]; //给label赋值
}
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="GetProductNum();"/>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Label ID="Label2" runat="server" Text="aa"></asp:Label>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
</div>
</form>
</body>
</html>
以上方式只能部署在Windows Server 2003+ IIS 6.0上，如部署在Windows Server 2008 + IIS 7.0上，除上述步骤外，还需要另外设置，具体如下：
1、在<system.webServer><handlers>下增加节点
<add name="ajaxpro" verb="*" path="*.ashx"type="AjaxPro.AjaxHandlerFactory,AjaxPro.2"/>
<!--程序部署在windows server 2008+IIS7.0，需要在此处声明AjaxPro2，才能正常使用-->
<system.webServer>
<handlers>
<add name="ajaxpro" verb="*" path="*.ashx" type="AjaxPro.AjaxHandlerFactory,AjaxPro.2"/>
</handlers>
</system.webServer>
或：
2、把应用程序池改为“经典模式”
