This is a bit of a continuation of a previous question.
Now I'm trying
to make a call
to an AJAX enabled
web service which I have defined within the
ASP.
NET MVC application (i.e. the MovieService.svc). But the service is never being called
in my getMovies javascript function.
This same technique of calling the AJAX
web service works ok if I try it
in a non
ASP.
NET MVC application, so it makes me wonder if maybe the
ASP MVC routes are interfering with things somehow when it tries
to make the AJAX
web service call.
Do you have any idea why my
web service isn't getting called? Code below.

var thegrid = jQuery("#editgrid");
for (var i = 0; i < jsondata.d.length; i++) {

Here's my RegisterRoutes code:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("*MovieService.svc*");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
}
Here's what my MovieService class looks like:
namespace jQueryMVC
{
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class MovieService
{
// Add [WebGet] attribute
to use HTTP
GET
[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json)]
public IList<Movie> GetMovies()
{
return Persistence.GetMovies();
}
}
}
