[javascript] How to create an Array with AngularJS's ng-model

I'm trying to create an array holding telephones, i have this code

<input type="text" ng-model="telephone[0]" />
<input type="text" ng-model="telephone[1]" />

But i can't access $scope.telephone

This question is related to javascript angularjs

The answer is

First thing is first. You need to define $scope.telephone as an array in your controller before you can start using it in your view.

$scope.telephone = [];

To address the issue of ng-model not being recognised when you append a new input - for that to work you have to use the $compile Angular service.

From the Angular.js API reference on $compile:

Compiles an HTML string or DOM into a template and produces a template function, which can then be used to link scope and the template together.

// I'm using Angular syntax. Using jQuery will have the same effect
// Create input element
var input = angular.element('<div><input type="text" ng-model="telephone[' + $scope.inputCounter + ']"></div>');
// Compile the HTML and assign to scope
var compile = $compile(input)($scope);

Have a look on JSFiddle

It works fine for me: http://jsfiddle.net/qwertynl/htb9h/

My javascript:

var app = angular.module("myApp", [])
app.controller("MyCtrl", ['$scope', function($scope) {
    $scope.telephone = []; // << remember to set this

You can do a variety of things. What I would do is this.

Create an array on scope that will be your data structure for the phone numbers.

$scope.telephone = '';
$scope.numbers = [];

Then in your html I would have this

<input type="text" ng-model="telephone">
<button ng-click="submitNumber()">Submit</button>

Then when your user clicks submit, run submitNumber(), which pushes the new telephone number into the numbers array.

$scope.submitNumber = function(){

One way is to convert your array to an object and use it in scope (simulation of an array). This way has the benefit of maintaining the template.

$scope.telephone = {};
for (var i = 0, l = $scope.phones.length; i < l; i++) {
  $scope.telephone[i.toString()] = $scope.phone[i];

<input type="text" ng-model="telephone[0.toString()]" />
<input type="text" ng-model="telephone[1.toString()]" />

and on save, change it back.

$scope.phones = [];
for (var i in $scope.telephone) {
  $scope.phones[parseInt(i)] = $scope.telephone[i];

This should work.

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

app.controller 'MainCtrl', ($scope) ->
  $scope.users = ['bob', 'sean', 'rocky', 'john']
  $scope.test = ->
    console.log $scope.users


<input ng-repeat="user in users" ng-model="user" type="text"/>
<input type="button" value="test" ng-click="test()" />

How to create an array of inputs with ng-model

  <li ng-repeat="n in [] | range:count">
    <input name="telephone-{{$index}}"
           ng-model="telephones[$index].value" >


  $scope.count = 3;_x000D_
  $scope.telephones = [];_x000D_
.filter("range",function() {_x000D_
  return (x,n) => Array.from({length:n},(x,index)=>(index));_x000D_
<script src="//unpkg.com/angular/angular.js"></script>_x000D_
<body ng-app="app" ng-controller="ctrl">_x000D_
      Array length_x000D_
      <input type="number" ng-model="count" _x000D_
      <li ng-repeat="n in [] | range:count">_x000D_
        <input name="telephone-{{$index}}"_x000D_
               ng-model="telephones[$index].value" >_x000D_
    </ol>  _x000D_
