Hi,

I am trying to get object array from my controller,
i can see that data is returned, but the javascript array (arr) remains empty....

here is a sample of my code, what am i doing wrong?

JS:

JavaScript

var arr = [];
    var onSuccess = function (data) {
            arr = data;
    };

        $.ajax({
            type: 'GET',
            url: 'MyController/GetCurrentAlarms',
            traditional: true,
            success: function (data) { onSuccess(data); },
        });

Controller:

C#

public JsonResult GetCurrentAlarms()
        {
            List<Alarm> list = new List<Alarm>();

            Alarm alm = new Alarm()
            {
                ID = 1,
                Name = "Alarm1"
            };

            list.Add(alm);

            alm = new Alarm()
            {
                ID = 2,
                Name = "Alarm2"
            };

            list.Add(alm);

            alm = new Alarm()
            {
                ID = 3,
                Name = "Alarm3"                
            };

            list.Add(alm);
         
            return Json(list.ToArray(), JsonRequestBehavior.AllowGet);
        }

Try this

JavaScript

var _url = '@Url.Action("GetCurrentAlarms" ,"Home")';
       $.ajax({
           url: _url,
           dataType: "json",
           type: "GET",
           contentType: 'application/json; charset=utf-8',
           success: function (data) {
               onSuccess(data);
           },
           error: function (xhr) {
               debugger;
               alert('error');
           }
       });

   });

   var arr = [];
   var onSuccess = function (data) {
       arr = data;
       alert(arr);
   };
