小编dat*_*est的帖子

我有一个ajax调用,它抓住了一个大的json列表.有没有什么方法可以创建一个进度条来获得json加载的实际值(例如,一个状态栏显示200个加载中的1个)？

现在我有一个非常基本的Ajax调用

function SendAjax(urlMethod, jsonData, returnFunction) {
    $.ajax({
        type: "GET",
        contentType: "application/json; charset=utf-8",
        url: urlMethod,
        data: jsonData,
        dataType: "json",
        success: function (msg) {
            if (msg != null) {
                ReturnJson(msg);
            }
        },
        error: function (xhr, status, error) {
            // Boil the ASP.NET AJAX error down to JSON.

            var err = eval("(" + xhr.responseText + ")");

            // Display the specific error raised by the server
            alert(err.Message);
        }
    });
}

试图获取音乐会的名称,日期和地点(存储在另一张桌子上),但它似乎没有工作,但它不断拉回null.

var test = from f in db.Concert
           where f.Name.StartsWith(concertName)
           select new
           {
               f.Name,
               f.StartDateTime,
               venues = from v in db.Venues
                        where v.ID == f.VenueID
                        select v.Address
           }

编辑:

Venue和Concert之间的关系是Concert有一个与Venue ID相关的VenueID.我需要传回一个字符串.就像是

foreach (var e in test)
{
   html += "<div> e.Name +":" + e.Address </div>;
}

我有两个动作,每当我明确调用第二个动作时,第一个动作仍会被调用.我需要能够在mysite.com/api/Awesome/GetSomeExamples中编写,而不会总是触发GetAllClasses

public class AwesomeController : Controller
{
   public IEnumerable<myClass> GetAllClasses()
   {
      //...some stuff
   }
   public IEnumerable<string> GetSomeExamples()
   {
       //...some stuff
   }
     //... also have some more actions which take in one parameter
}

我的路由是这样的,但不起作用

 public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "ActionApi",
                url: "api/{controller}/{action}/{id}",
                defaults: new { id = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
        }

我收到错误:找到了与请求匹配的多个操作
