Calculate the sum of values for each ng-model in array angularjs

Question

{ "specific": { "first":{ "title":"222", "items":[ { "z": "1", "s":"2", "p":"3", }, { "z": "12", "s":"12", "p":"12" } ], "results":{ "z": "13", "s":"14", "p":"15" } } } }

<div class="row" ng-repeat="(item, q)  in first.items">
  <input ng-model="q.z">
  <input ng-model="q.s">
  <input ng-model="q.p">

Results should calculate the values for repeated elements in items (for example, item1.z + item2.z = results.z).

How can I calculate the values for each repeated element for item in items with angularJS?

It might help you!! stackoverflow.com/questions/22731145/… — Anil Singh

Trying to like this.

In Template

<td>Total: {{ getTotal() }}</td>

In Controller

$scope.getTotal = function(){
    var total = 0;
    for(var i = 0; i < $scope.cart.products.length; i++){
        var product = $scope.cart.products[i];
        total += (product.price * product.quantity);
    }
    return total;
}

$scope.getTotal = function(){         var total = 0;         for(var i = 0; i < $scope.first.items.length; i++){             var item = $scope.first.items[i];             total += item.z;         }         return total;     }

as a result it returns 112 (item1 z, item2 z), the same result if use <div ng-init="items.total.z = items.total.z + q.z"></div> What i'm missing?

try to this. <div ng-init="items.total.z = (items.total.z) + (q.z)"></div>

fixed with ` total = total + parseInt(item.z);` Thanks for your help!
