Pushing input values from ng-repeat into array with AngularJS

Question

I have a ng-repeat displaying a list of products with an input each. I want to be able to push the value of each input together with a parameter from every item into a new array to create an order.

So far I managed to do it individually, but not all together.

Here's my HTML:

<div ng-repeat="pa in products">
  <div>
    <h2>{{pa.nom}}</h2>
    <input type="number" ng-model="basket" min="0" max="20" step="1" ng-init="basket=0">
  </div>
</div>
<a ng-click="insert(pa.nom,basket)">Add items</a>

And the function:

$scope.singleorder = [];

$scope.insert = function(nom, basket){
  $scope.singleorder.push({
    'product': nom,
    'number': basket
  });
  console.log($scope.singleorder);
}

I assume the issue has to do with keeping track of the different models of the inputs on each repeat, but I don't know how to deal with it.

I've also tried adding each item individually using ng-change on the input, but it will push an object on every change, duplicating the item on every change, so it won't work.

Any tips?

Answer 1

The trick would be to have an input for each repeated element in ng-repeat.

<div ng-repeat="pa in products">
    {{pa.nom}}
    <input type="number" ng-model="pa.basket">
</div>
<a ng-click="insert()">Add items</a>

insert() will loop over products and insert in singleOrder when basket has been set:

$scope.insert = function() {
    for (var i = 0; i < $scope.products.length; i++) {
        if ($scope.products[i].basket) { // if input has been set
            $scope.singleorder.push({
              'product': $scope.products[i].nom,
              'number': $scope.products[i].basket
            });
        }
    }
}
