         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";

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
