第一步：引用AjaxPro.2.dll(http://www.ajaxpro.info/ 下载)
第二部：配置web.config
配置一：
<?xml version="1.0"?>
<configuration>
<appSettings/>
<connectionStrings/>
<system.web>
<compilation debug="true"/>
<authentication mode="Windows"/>
<httpHandlers>
<add verb="*" path="*.asmx" type="Microsoft.Web.Services.ScriptHandlerFactory" validate="false"/>
<add verb="POST,GET" path="ajaxpro/*.ashx" type="AjaxPro.AjaxHandlerFactory, AjaxPro.2"/>
</httpHandlers>
</system.web>
</configuration>
配置二：
<?xml version="1.0"?>
<configuration>
<configSections>
<sectionGroup name="ajaxNet">
<section name="ajaxSettings" type="AjaxPro.AjaxSettingsSectionHandler,AjaxPro.2" requirePermission="false" restartOnExternalChanges="true"/>
</sectionGroup>
</configSections>
<ajaxNet>
<ajaxSettings>
<urlNamespaceMappings useAssemblyQualifiedName="false" allowListOnly="false">
</urlNamespaceMappings>
<jsonConverters includeTypeProperty="true">
</jsonConverters>
<debug enabled="false"/>
<token enabled="false" sitePassword="password"/>
</ajaxSettings>
</ajaxNet>
<appSettings/>
<connectionStrings/>
<system.web>
<compilation debug="true"/>
<authentication mode="Forms"/>
<httpModules>
</httpModules>
</system.web>
<location path="ajaxpro">
<system.web>
<httpHandlers>
<add verb="*" path="*.ashx" type="AjaxPro.AjaxHandlerFactory,AjaxPro.2"/>
</httpHandlers>
</system.web>
</location>
</configuration>
第三步实现：
实现一：
（Default.aspx.cs）
using System;
using AjaxPro;
namespace My
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
AjaxPro.Utility.RegisterTypeForAjax(typeof(_Default));
}
[AjaxPro.AjaxMethod]
public string GetTime(string name)
{
return name + ":" + DateTime.Now.ToString();
}
}
}
（Default.aspx）
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="My._Default" %>
<!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></title>
<script language="javascript" type="text/javascript">
function A1() {
My._Default.GetTime("asd", B1);
}
function B1(a) {
alert(a.value);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input onclick="A1()" />
</div>
</form>
</body>
实现二：
（Default.aspx.cs）
using System;
using AjaxPro;
[AjaxPro.AjaxNamespace("My")]
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
AjaxPro.Utility.RegisterTypeForAjax(typeof(_Default));
}
[AjaxPro.AjaxMethod]
public string GetTime(string name)
{
return name + ":" + DateTime.Now.ToString();
}
}
（Default.aspx）
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!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></title>
<script language="javascript" type="text/javascript">
function A1() {
My.GetTime("asd",B1);
}
function B1(a) {
alert(a.value);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input onclick="A1()" />
</div>
</form>
</body>
</html>
