I have one controller, controller's template/view as below,

myController

angular.module('myApp', []).
controller('myController', ['$scope', function($scope) {
        $scope.myObject = {};
}]);

myView

<div class="container" ng-app="myApp">
    <form name="myForm" novalidate ng-controller="myController">
        <div class="form-group">
            <label for="firstname" class="control-label col-xs-2">Name</label>
            <div class="col-xs-10">
                <input type="text" ng-model="myObject.firstname" id="firstname">
            </div>
        </div>
        <div class="form-group">
            <label for="lastname" class="control-label col-xs-2">LastName</label>
            <div class="col-xs-10">
                <input type="text" ng-model="myObject.lastname" id="lastname">
            </div>
        </div>
    </form>
</div>

here whenever user enters any data it gets reflected to myObject with firstname and lastname as dynamic properties for myObject. Now my new requirement is to add multiple dynamic views for firstname and lastname in the same view(For that I will be creating a directive and appending dynamically), and now I want myObject to be an array of objects like

myObjectArray = [{firsname: "abc", lastname: "xyz"},{firsname: "abc", lastname: "xyz"},{firsname: "abc", lastname: "xyz"},{firsname: "abc", lastname: "xyz"}]

and here each object should be populated through dynamically added views by user input using angular two way binding. But I am not sure how can I achieve this with angular, how to add object to array whenever there is a new directive template added to view dynamically.

In Angular you should avoid thinking in terms of dynamic controls.

Here is the approach

  1. You want to list firstname, lastname objects
  2. You want to add a new object to this list.

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {

  $scope.items = [];

  $scope.itemsToAdd = [{
    firstName: '',
    lastName: ''
  }];

  $scope.add = function(itemToAdd) {

    var index = $scope.itemsToAdd.indexOf(itemToAdd);

    $scope.itemsToAdd.splice(index, 1);

    $scope.items.push(angular.copy(itemToAdd))
  }

  $scope.addNew = function() {

    $scope.itemsToAdd.push({
      firstName: '',
      lastName: ''
    })
  }
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<body ng-app="plunker" ng-controller="MainCtrl">
  <p>Hello {{name}}!</p>

  <div ng-repeat="item in items">
    {{item.firstName}} {{item.lastName}}
  </div>
  <div ng-repeat="itemToAdd in itemsToAdd">
    <input type="text" ng-model="itemToAdd.firstName" />
    <input type="text" ng-model="itemToAdd.lastName" />
    <button ng-click="add(itemToAdd)">Add</button>
  </div>
  <div>
    <button ng-click="addNew()">Add new</button>
  </div>
</body>

Notice these are simply talking about model. Here is a plunk

If I have to add/append this(Firstname/Lastname) view and push its values to object how we can do that? consider Firstname and lastname is a directive and on click of particular button I have to append more and more views and push its values to array.. – santosh kore Feb 20 '15 at 10:10

@santoshkore - I've edited my answer. Again - You should let angular bindings drive the controls rather than control them manually. This edit should solve your problem – Abhinav Gujjar Feb 20 '15 at 11:30

What does the ng-repeat of item in items do in this example? – Matheno Apr 18 '16 at 7:01
