运用ajax提示未定义
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));
    }

html   :

function   GetMac()
{
    var   send1   =   document.getElementById( "send1 ").value
document.getElementById( "send2 ").value=DemoMethods.GetCustomerMac(send1).value

}


namespace   AjaxSample
{
  public   class   DemoMethods
  {
        [Ajax.AjaxMethod]
    public   string   GetCustomerMac(string   send)  
    {  
        return   send*5;
      }

运行时提示‘DemoMethods‘未定义

谁能帮我解决一下

------解决方案--------------------
在Web.config文件的 <System.Web> </System.Web> 里加入:
<httpHandlers>
<add verb= "* " path= "*.ashx " type= "AjaxPro.AjaxHandlerFactory,AjaxPro.2 "/>
</httpHandlers>
------解决方案--------------------
document.getElementById( "send2 ").value=DemoMethods.GetCustomerMac(send1).value
里的DemoMethods改为AjaxSample.DemoMethods
------解决方案--------------------
我这段放到config 里面

<httpHandlers>
<remove verb= "* " path= "*.asmx "/>
<add verb= "* " path= "*.asmx " validate= "false " type= "Microsoft.Web.Script.Services.ScriptHandlerFactory, Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 "/>
<add verb= "* " path= "*_AppService.axd " validate= "false " type= "System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 "/>
<add verb= "GET,HEAD " path= "ScriptResource.axd " type= "System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 " validate= "false "/>
</httpHandlers>

我也遇到了同样的问题，不过 whw123456 的办法帮我解决了。LZ 看你的代码应该把命名空间也写上：
function GetMac()
{
var send1 = document.getElementById( "send1 ").value
document.getElementById( "send2 ").value=AjaxSample.DemoMethods.GetCustomerMac(send1).value

}
还有再在webconfig中把 whw123456 说的在加上。
whw123456 多谢，我一会开个帖子，把我的代码贴出来，你来随便回给贴。我把分给你，表示感谢。
