Javascript Dotnetnuke从模块调用ajax

我现在尝试使用ajax调用构建dnn模块。但是有一个jquery错误声明

SyntaxError:意外标记您遇到的问题是DNN没有正确处理您正在调用的请求URL。如果要在DNN中调用服务URL，则需要设置路由来处理调用

namespace Christoc.Com.Modules.SlidePresentation.services
{
    public class SlidePresentationRouteMapper : IServiceRouteMapper
    {
        public void RegisterRoutes(IMapRoute mapRouteManager)
        {
            mapRouteManager.MapRoute("SlidePresentation", "{controller}.ashx/{action}",
               new[] {"Christoc.Com.Modules.SlidePresentation.services"});
        }
    }
}

在控制器中，可以定义可用的方法

[DnnAuthorize(AllowAnonymous = true)]
public ActionResult ListOfSlides()
{
    try
    {   
        var slides = Slide.GetSlides(ActiveModule.TabID, ActiveModule.ModuleID);
        return Json(slides, JsonRequestBehavior.AllowGet);
     }
     catch (Exception exc)
     {
         DnnLog.Error(exc);
         return Json(null, JsonRequestBehavior.AllowGet);
     }
}

示例Javascript

 //get slides on initialization
    this.init = function(element) {
        //var data = {}; //removed because we don't need this
        //data.moduleId = moduleId; //removed because we don't need this when calling setModuleHeaders
        //data.tabId = tabId; //removed because we don't need this
        //serviceFramework.getAntiForgeryProperty(); //removed because we don't need this
        $.ajax({
            type: "POST",
            cache: false,
            url: baseServicePath + 'ListOfSlides',
            //data: data,
            //dataType:"json",
            beforeSend: serviceFramework.setModuleHeaders
        }).done(function(data) {
            viewModel.slides = ko.utils.arrayMap(data, function(s) {
                return new slide(s);
            });
            ko.applyBindings(viewModel);
            $(element).jmpress();
        }).fail(function () {
            Console.Log('Sorry failed to load Slides');
        });
    };

下面是一个示例模块，可以实现这一点

几年前我在这个模块上做了一个用户组视频。

谢谢。我现在明白了。：）
