I am working on MVC3 and following is my controller

 

  public List<int> ddlTransType_Change(int DocID)

        {

 

            return UserDocumentServive.getSelectedUsers(DocID);

 

        }

My Ajax

 

  $.ajax({

                type: 'GET',

                url: "/MIS.MVC/" + "DocumentApproval/ddlTransType_Change",

                data: {

                    'DocID': $("#ddlTransType").val().trim()

                },

                success: function (result) {

                    alert(result.value)

},

error: function (e) {

                    alert("Error:Unable to load data from server");

                }

            });

Controller returns a list of int values i.e {1,74,23,1} and I want to show them in alert. any idea how to do it .?

    Re: Return List to ajax mvc3

    If you are using MVC3, its better to return json data back to your ajax success call

     

    public ActionResult ddlTransType_Change(int DocID)

        {

             List<int> list = UserDocumentServive.getSelectedUsers(DocID);;

            return Json(new

            {

                list = list

            },JsonRequestBehavior.AllowGet);

        }

    Then your ajax call changes to

     

     $.ajax({

                    type: 'GET',

                    url: "/MIS.MVC/" + "DocumentApproval/ddlTransType_Change",

                    data: {'DocID': $("#ddlTransType").val().trim()},

                    dataType: 'json',

                    success: function (result) {

                                               var list=result.list;

                  $.each( list, function( index, value )

                                             {

                                                alert(value);

                                               });

                                                 },

    error: function (e) {

                        alert("Error:Unable to load data from server");

                    }

            });
