Binding nested array in Angular view


Binding nested array in Angular view

hope this fix your issue The best solution is to concat all the arrays using a reduce function and a concat function before you serve it up to a ui. You can either do this through a filter or just within the controller upon receiving the data:
code :
vm.resultCategories = vm.resultCategories.reduce(function(last,next){
    return last.concat(next);
})
vm.resultCategories = new Array(vm.resultCategories.join());

To fix the issue you can do Modify the code to wrap inside scope.$apply because you are modifying the property outside the angular scope you have to use scope.$apply() to watch the values

Any of those help Don't bind original object to a form but do a copy (angular.copy) of it before editing and bind a copy in a form. Then after "Save" copy back object bound to a form back to the original object.

Hope this helps I have an array called simpleSearchResultsArray in main viewModel -QuoteSimpleSearchVM. , When you call
code :
SimpleSearchResultsObj.BindDataToQuotesDetailVM(this);
self.BindDataToQuotesDetailVM = function () {
    self.quoteDetailsObj = new QuoteDetails(); 
    self.quoteDetailsObj.SoldToAccount("SoldToAccount test");

will be helpful for those in need In Angular you should avoid thinking in terms of dynamic controls.
Here is the approach
code :
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>
Angular binding object with array from component to view with ngModels

Angular binding object with array from component to view with ngModels

hop of those help? The problem is, whatever the input name specified, it will be considered as just text. Should not reference any Object or Array.But with slight modifications, there is a chance to obtain the same data structure with updated data.
All elements are binded in one way, so make it two way binding. So whenever input value changes, The binded element value updates.
code :
 [(ngModel)]="question.question"
<form #form="ngForm" (ngSubmit)="createQuestion()" class="mt-4">
...
<button [disabled]="!form.valid"  
createQuestion() {
        console.log(this.question);
    }
