c# – 使用HTTPStatusCodeResult和jQuery的自定义错误消息

我有一个控制器动作,它将一些 JSON结果返回给jQuery Full Calendar插件.如果出现错误,我返回带有自定义错误消息的HTTPStatusCodeResult,但是我无法显示自定义错误消息.警报框中显示的所有内容都是默认的Http状态(即：’Forbidden’或’Internal Server Error’)

返回错误消息的控制器代码

else if(id != CurrentUser.UserId)
{
    return new HttpStatusCodeResult(403,"You are not authorised to view this.");
}
else
{
    return new HttpStatusCodeResult(500,"There was an error on the server.");
}

jQuery代码

$(document).ready(function () {
             $('#calendar').fullCalendar({
                 header: {
                     left: 'prev,next today',center: 'title',right: 'month,agendaWeek,agendaDay'
                 },height: 600,eventSources: [{
                     url: events,type: 'Get',error: function(response,status,error) {
                         alert(response.statusText);
                     }
                 }],allDayDefault: false,selectable: true,eventClick: function (event) {
                     if (event.url) {
                         $('#details').load(event.url);
                     }
                 },
