Question

我正在做一个简单的＆＃34;添加到购物车＆＃34;系统。我希望我的篮子中的物品不会消失，所以我试图使用angularjs饼干。它可以在不添加cookie项目的情况下工作，添加和删除ok。

var app = angular.module('myApp', ['ui.bootstrap','ngCookies']);
app.controller('menusCtrl', ['$cookies',function($scope, $http,$cookies) {
   $http.get("getContent.php").success(function (response) {$scope.items = response.menus;});
   $scope.basketlist = [];
   $scope.updateCart = function (index) {
    var item = $scope.items[index];
    $scope.basketlist.push({quantity: 1, price: item.menu_price,no:item.menu_no,image:item.menu_img});
    $cookies.put("basketlist",$scope.basketlist);
   }
    $scope.remove = function(index) {
      var itemtodelete = $scope.basketlist.indexOf(index);
        $scope.basketlist.splice(index, 1);
    }
}]);

我插入/angularjs/1.4.2/和/1.4.2/angular-cookies.js

我收到了这些错误：

Answer 1

$scope.mybasket = JSON.parse($cookies.get('mybasket'));
$cookies.put('mybasket',JSON.stringify($scope.mybasket));

我使用JSON.stringify和JSON.parse并且它有效。

在angularjs中使用cookies 1.4.2
