Angular : pass mutliple values to the controller - angularjs

Question

Let's say i have a drop drown list that i add dynamicly in my html template:
<button type="button" ng-click="addRow()" style="margin-bottom:5px;">Add cities </button>
<div ng-repeat="city in cities">
<select ng-model="cities_$index"
ng-options="n.id as n.name for n in citiesList"
class="form-control"
ng-required="true">
<option value="">-- Choose City --</option>
</select>
</div>
Angular Controller :
$scope.addRow = function () {
var newrow = [];
if ($scope.cities.length === 0) {
newrow.push({ 'cities': $scope.cities_0 });
}
else {
$scope.cities.forEach(function (row, key) {
var city= '$scope.cities_'+key; // in php i can do this
//but i dont know how to do it with Js/Angular
console.log('row' + city);
newrow.push({ 'cities': city});
console.log(newrow);
});
}
$scope.cities.push(newrow);
}
I tried this to retrieve the values from the cities selected but i have undefined values.
$scope.send = function () {
angular.forEach($scope.cities, function (value, key) {
console.log(value.id); // the id from the ng-options
};
In a regular html code i just add name="city" and i retrieve all the cities added in my input box. But how i can retrieve thoses cities from the ng-model in my controller ?
I know i'm doing something wrong, but since i'm new with angular i'm trying !!
Thank you

Answer 1

supposing that the key (city) is inside your datas array, you can do :
<div ng-repeat="data in datas">
<input type="text">{{data.name}}
</div>

ng-model is still unique. What you are missing here is that ng-repeat creates a child scope for each item. Therefore, the value of ng-model is unique for EACH child scope. ng-model doesn't behave the same way as plain HTML input and having multiple inputs with the same ng-model will only point to the same object in memory. And not, "add up" values to the property city as you would expect in plain HTML inputs.
If you are using the object datas in your ng-repeat, it's kind of common practice that your <input /> would bind to a item property of datas.
<div ng-repeat="data in datas">
<input type="text">{{data.city}}
</div>
