Dealing with Array Splicing Issues in Angular

Being fairly new to the world of AngularJS, I suspect that I am just making a simple mistake.

My goal is to splice the cardTypes array at the var newCard = cardTypes.shift(); line rather than using .shift() so that I can consider my ng-repeat index.

While it works perfectly fine with .shift(), no data comes through at all when I attempt to use .splice(index, 1).

I would greatly appreciate any assistance provided.

    .controller('CardsCtrl', function($scope, $ionicSwipeCardDelegate) {
  var cardTypes = [
    { title: 'Swipe down to clear the card', image: 'img/pic.png' },
    { title: 'Where is this?', image: 'img/pic.png' },
    { title: 'What kind of grass is this?', image: 'img/pic2.png' },
    { title: 'What beach is this?', image: 'img/pic3.png' },
    { title: 'What kind of clouds are these?', image: 'img/pic4.png' }
  ];

  $scope.cards = Array.prototype.slice.call(cardTypes, 0, 0);

  $scope.cardSwiped = function(index) {
    $scope.addCard();
  };

  $scope.cardDestroyed = function(index) {
    $scope.cards.splice(index, 1);
      $scope.addCard();
  };

  $scope.addCard = function() {
    var newCard = cardTypes.shift();
    newCard.id = Math.random();
    $scope.cards.push(angular.extend({}, newCard));
  }
})

.controller('CardCtrl', function($scope, $ionicSwipeCardDelegate) {
  $scope.goAway = function() {
    var card = $ionicSwipeCardDelegate.getSwipebleCard($scope);
    card.swipe();
  };
});

Answer №1

Are you referring to the addCard method?

I don't see an index variable in that method, so perhaps you intended to use .splice(0, 1); to remove the first item instead?

Including 'use strict'; at the beginning of all my JavaScript files has been beneficial for identifying and resolving issues like this.
