chatbox.chat.server.send(this.options.id, this.$input.val()); //这句话都不执行

下面这个我也配置了

using Microsoft.AspNet.SignalR;
using Owin;
using Microsoft.Owin;

[assembly: OwinStartup(typeof(CarRental.Web.App_Start.Startup))]

namespace CarRental.Web.App_Start
{
public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        HubConfiguration configuration = new HubConfiguration
        {
            EnableJSONP = true
        };
        app.MapSignalR(configuration);
    }
}
}

就是不会运行到后面来

public void Send(string id, string message)
    {
        if (!Context.User.Identity.IsAuthenticated)
        {
            return;
        }
        Principal principal = (Principal)Context.User;
        string name = principal.DisplayName;
        string dateTime = DateTime.Now.ToString("HH:mm");
        int idA = principal.ID;
        int idB = int.Parse(id);
        //向自己发送
        Clients.Caller.addMessageA(message, dateTime, idB, name);

        //检查对方是否在线
        if (!_onlines.ContainsKey(idB) || _onlines[idB] <= 0)
        {
            Clients.Caller.addMessageSys("对方是离线状态", dateTime, idB);
        }

        //向对方发送
        Clients.Group(idB.ToString()).addMessageB(message, dateTime, idA, name);

        ChatSvc.AddMessage(idA, idB, message);
    }

请问一下这怎么解决，看了很多教程都做不出来。
