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");

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();
}
}
}
