我对aspx和asmx页面之间的连接有问题

我的homepage.asmx是：

namespace TA.WebPage
{

    /// <summary>
    /// Summary description for WebService1
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    [System.Web.Script.Services.ScriptService]
    public class HomePage : WebService
    {

        [WebMethod]
        public A GetA()
        {
           return new A();
        }
    }
}

谢谢。

我很困惑，JavaScript不能运行代码隐藏？

  <head>
    <script type="text/javascript" language="javascript">
        function GetAObj() {
            TA.WebPage.HomePage.GetA(Success);
        }
    </script>
  </head>

    <body>
        <asp:ScriptManager ID="ScriptManager1">
            <Services>
                <asp:ServiceReference Path="HomePage.asmx" />
            </Services>

        </asp:ScriptManager>

    </body>
