  </tr>

  </table>

  Jquery引用和登录事件

  代码

  

复制代码 代码如下:

  <script src="js/jquery-1.4.2.min.js" type="text/javascript"></script>

  <script type="text/javascript" language="javascript">

  $(document).ready(function()

  {

    $('#btnSignin').click

    (function()

    {

      $.ajax

      (

      {

        type: "POST", 

        contentType: "application/json",

        url: serviceURL+"/UserLogin",

        data: "{UserLoginID:'"+$('#txtLoginID').val()+"',UserLoginPW:'"+$('#txtLoginPW').val()+"'}",      

        dataType: 'json',

        success: function(result)

        {

         var user = eval(result.d);

          location.href = "Welcome.aspx?userID="+user.UserID

        },

        error: function(result, status)

        {

        if(status == 'timeout')

        {

        alert("The request timed out, please resubmit");

        }

        else

        {

        if(result.responseText !="")

        {

        eval("exception = "+result.responseText);

             alert(exception.Message);

            }

          }

        }

      }

      );

    }

    );

    });

   

    $(document).ready(function()

  {

    $('#btnSignup').click

    (function()

    {

      location.href = "Signup/Signup.aspx";

    })   

    });

  </script>

  serviceURL类似:var serviceURL = "http://localhost:1742/SoldierServices.asmx";

  WebService代码:

  代码

  

复制代码 代码如下:

  /// <summary>

  /// Summary description for SoldierServices

  /// </summary>

  [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 SoldierServices : System.Web.Services.WebService

  {

  [WebMethod]

  public User UserLogin(string UserLoginID, string UserLoginPW)

  {

  LoginBusiness lb = new LoginBusiness();

  return lb.UserLogin(UserLoginID, UserLoginPW);

  }

  [WebMethod]

  public User GetUserInfo(string UserID)

  {

  LoginBusiness lb = new LoginBusiness();

  return lb.GetUserInfo(UserID);

  }

  }

  注意:[System.Web.Script.Services.ScriptService]默认是注释的,要把注释去掉
