1. 新建一个项目,在引用中添加引用Ajax.dll,Ajax.dll位于下载的压缩包里面。
2.建立HttpHandler,在web.config里面加上
< configuration>
< system.web> < httpHandlers> < add verb="POST,GET" path="ajax/*.ashx" type="Ajax.PageHandlerFactory, Ajax" /> < /httpHandlers> < system.web> < /configuration> |
using System;
using System.Web; namespace AjaxSample { /**//// < summary> /// Summary description for Methods. /// < /summary> public class DemoMethods { [Ajax.AjaxMethod] public string GetCustomerMac(string clientIP) //这里输入客户端IP,这个函数知识测试用,你也可以写一个其他的简单一点的函数代替 { string mac = ""; System.Diagnostics.Process process = new System.Diagnostics.Process(); process.StartInfo.FileName = "nbtstat"; process.StartInfo.Arguments = "-a "+clientIP; process.StartInfo.UseShellExecute = false; process.StartInfo.CreateNoWindow = true; process.StartInfo.RedirectStandardOutput = true; process.Start(); string output = process.StandardOutput.ReadToEnd(); int length = output.IndexOf("MAC Address = "); if(length>0) { mac = output.Substring(length+14, 17); } process.WaitForExit(); return mac.Replace("-", "").Trim(); } } } |
4.写javascript,新建一个名为default.js文件如下
function GetMac()
{ var clientIP="192.168.0.1"; //document.getElementById("Mac").value=DemoMethods.GetCustomerMac(clientIP).value alert(DemoMethods.GetCustomerMac(clientIP).value); } |
在页面上< head>中引用default.js :
< script language="javascript" src="default.js">< /script> |
onclick="javascript:GetMac()"
< INPUT style="Z-INDEX: 101; LEFT: 392px; POSITION: absolute; TOP: 176px" type="button" value="客户端获取IP" onclick="javascript:GetMac();"> 6.在page页面的Page_Load事件中加上 private void Page_Load(object sender, System.EventArgs e) { // 在此处放置用户代码以初始化页面 Ajax.Utility.RegisterTypeForAjax(typeof(AjaxSample.DemoMethods)); } |
7.修改Global.asax的Application_Start事件,设置Ajax的HandlerPath :
protected void Application_Start(Object sender, EventArgs e)
{ Ajax.Utility.HandlerPath = "ajax"; } |
需要注意的是:该版本的.net Ajax需要手工在中Global.asax加上Ajax.Utility.HandlerPath = "ajax"; 配置文件web.config必须加上HttpHandler的配置信息!
该开发包的新版本还没有来得及体验,估计新版本中会方便一些,可能会去掉手动的设置Global.asax的Application_Start事件中加上Ajax.Utility.HandlerPath = "ajax";以及其他麻烦的设置!
