How to get data from server using Jquery in Asp.Net MVC 4 Application

Question

I'm trying get data from database in my application,my js code looks like:

$(function () {
 $("#getNotices").button().click(function () {
     $.get("/Notice/GetItems", function (data, statusText) {
         console.log(data);
     });
 });
});

My controller:

[HttpGet]
 public IEnumerable<Notice> GetItems()
 {
    return db.GetItems();
 }

And Method GetItems:

public IEnumerable<Notice> GetItems()
{
    return _db.Notices;
}

It always returns:

Tell me please how i can get data, database keeps data i checked,from database? Thanks for your answers!

maybe just silly idea but have you tried to call return _db.Notices.ToList(); in GetItems()? — Jaroslav Kadlec

@JaroslavKadlec yes, I tried, it returns : "System.Collections.Generic.List'. — Uladz Kha

does it change behavior in case you'd change it in way it's described in my answer? e.g. change signature of method to return JsonResult? Then potentially try remove [HttpGet] attribute and try to acquire data via POST but that would more point to wrong configuration or something like that. — Jaroslav Kadlec

Use Json Action Results as follows:-

[HttpGet]
 public JsonResult GetItems()
 {
     return Json(db.GetItems().ToList(), JsonRequestBehavior.AllowGet);
 }

You could try change code in your GetItems() method into:

public JsonResult GetItems()
{
    return Json(_db.Notices.ToList());
}

This way you're saying framework it should represent result as JSON string, in case you do not so then just .ToString() method is called on your result in background and then exactly this string is sent to your UI.
