问题描述

大家好..

我正在使用ajax自动完成扩展器编写一个Web服务，但徒劳无功.随着事情的进展我逐渐淡了.我尝试了两天，但对jquery和ajax无效.
我的代码是:
在aspx页面上:

hi all..

I am writing a web service in using ajax autocomplete extender.but all in vain.I am fade up with the thing going on.i am trying for two days but nothing works with jquery and ajax.
my code is:
ON aspx page:

<asp:ScriptManager ID="ScriptManager1" EnablePageMethods="true" runat="server">
  <Services>
  <asp:ServiceReference  Path="~/WebService1.asmx" />
  </Services>
        </asp:ScriptManager>

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
         <asp:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" MinimumPrefixLength="1" ServiceMethod="GetUsers"      ServicePath="~/WebService1.asmx"      TargetControlID="TextBox1" EnableCaching="true" CompletionInterval="10" />

我的Web服务代码.

My web service code.

[WebService(Namespace = "http://tempuri.org/")]
  [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
  [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 WebService1 : System.Web.Services.WebService
  {
      [WebMethod]
      public List<string> GetUsers(string prefixText, int count)
      {
          WebSolution.DAL.databaseDataContext DC = new WebSolution.DAL.databaseDataContext();
          var Customers = from p in DC.users
                          where p.firstName.Contains(prefixText)
                          select p.firstName;
          return Customers.ToList();
      }
  }

我能够调用Web服务方法并在浏览器中查找记录.
请告诉我.shld我必须更改web.config进行其他操作.否则任何答复都将得到兑现.您可以使用jquery向我建议.
