js

var myapp = angular.module('myapp', []); myapp.controller('myctrl', function($scope) {     $scope.ids = [1, 2, 3];     $scope.users = $scope.ids.map(function(id) {         return {             id: id,             comment: "",             location: ""         };     });     $scope.locations = ['india', 'usa', 'jermany', 'china', 'dubai'];     $scope.adduser = function() {         var data = $scope.users.map(function(user) {             //i trying method             /*$scope.user.location.push($scope.locations[0]);               $scope.user.location = $scope.user.location.slice();               console.log($scope.user.location) doesnt work. */             return {                 "userid": user.id,                 "manualcomment": user.comment,                 "location": user.location             }         });         console.log("data", data)     } });

one way execute ng-init code in $timeout callback. problem comes execution order between directives. delay init $timeout trigger @ next digest.

here example :

var myapp = angular.module('myapp', []);  myapp.controller('myctrl', function($scope, $timeout) {    $scope.ids = [1, 2, 3];    $scope.users = $scope.ids.map(function(id) {      return {        id: id,        comment: "",        location: ""      };    });    $scope.locations = ['india', 'usa', 'jermany', 'china', 'dubai'];    $scope.initlocation = (user) => {      $timeout(() => {        user.location = $scope.locations[0];      });    }    $scope.adduser = function() {      var data = $scope.users.map(function(user) {        //i trying method        /*$scope.user.location.push($scope.locations[0]);          $scope.user.location = $scope.user.location.slice();          console.log($scope.user.location) doesnt work. */        return {          "userid": user.id,          "manualcomment": user.comment,          "location": user.location        }      });        console.log("data", data)    }    });
<div ng-app="myapp">    <div ng-controller="myctrl">      <form role="form" name='userform' novalidate>        <div class="container">          <div class="row" ng-repeat="user in users">            <div class="form-group">              <div class="col-md-3">                <label>id</label>                <input ng-model="user.id" id="user.id" name="user.id" placeholder="enter bugid" type="text" required readonly disabled>              </div>              <div class="col-md-3">                <label>comments</label>                <textarea ng-model="user.comment" id="textarea1" rows="1" required></textarea>              </div>                <div class="col-md-3 ">                <label>location</label>                  <select ng-model="user.location" ng-options="v v in locations" ng-init='initlocation(user)' name="select2" required>                            </select>              </div>            </div>            </div>        </div>        <div class="buttoncontainer text-center btn-container">          <br>          <button ng-disabled="userform.$invalid" type="button" id="adduser" ng-click="adduser()">add user</button>          <button type="button" class="btn button--default btn--small pull-center">close</button>        </div>      </form>      <script src="https://code.jquery.com/jquery.min.js"></script>      <link href="https://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet" type="text/css" />      <script src="https://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js"></script>      <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js"></script>    </div>
