问题描述
我正在尝试从启用AJAX的WCF服务中的Handsontable中显示数据，但是它什么也不显示.
I'm trying to display data in a Handsontable from an AJAX-enabled WCF Service but it does not show anything.
CarsService.svc:
[DataContract]
public class Car
{
[DataMember]
public string Name { get; set; }
[DataMember]
public string Year { get; set; }
}
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class CarsService
{
[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json)]
public IEnumerable<Car> GetCars()
{
var cars = new List<Car>();
var car1 = new Car()
{
Name = "Kia",
Year = "2008"
};
var car2 = new Car()
{
Name = "Nissan",
Year = "2009"
};
cars.Add(car1);
cars.Add(car2);
return cars;
}
}
