我在使用angularjs中的$ cookies删除和编辑cookie对象时遇到问题。我想建立一个商店,我正在使用putObject函数将产品添加到$ cookies全局变量(我没有使用put因为我有多个参数)。我想添加从商店中删除和编辑产品的功能,并从cookie中删除和编辑一个对象。请帮帮我!
以下是我的代码片段(我想从'产品' Cookie中删除/编辑对象):
app.controller('Store', ['$scope', '$cookies', 'x2js', '$http',
function($scope, $cookies, x2js, $http){
this.products = $cookies.getObject('products');
if(!this.products) {
var self = this;
$http.get('assets/xml/products.xml').success(function(data) {
self.products = data.products.product;
for(var i = 0; i < self.products.length; i++) {
self.products[i].id = parseInt(self.products[i].id);
self.products[i].netto = self.products[i].netto + '.00';
self.products[i].tax = parseInt(self.products[i].tax);
self.products[i].brutto = parseFloat(self.products[i].brutto);
self.products[i].rating = parseInt(self.products[i].rating);
};
});
}
$scope.product = $cookies.getObject('product') || {};
$scope.$watch('product', function() {
$cookies.putObject('product', $scope.product);
}, true);
this.addProduct = function() {
if(this.countCategories() >= 2) {
if(this.validateForm()) {
var product = {
id: this.products.length + 1,
name: $scope.product.name,
code: $scope.product.code,
image: $scope.product.image,
netto: this.intToFloat($scope.product.netto, 2),
tax: $scope.product.tax,
brutto: this.calculatePriceBr(),
rating: parseInt(this.ratingChecked()),
category: this.categoryChecked(),
option: this.optionChecked(),
selected: $scope.product.selected
};
this.products.push(product);
$scope.product = {};
$cookies.putObject('products', this.products);
$('#product-add').modal('hide');
return true;
} else {
return;
}
} else {
return;
}
};
})();

希望这就是你要找的东西。
我已根据您的代码进行了一些测试(简化):
var app = angular.module('myApp', ['ngCookies']);
app.controller('Store', Store);
Store.$inject = ['$scope', '$cookies', '$http'];
function Store($scope, $cookies, $http) {
var vm = this;
vm.products = [];
vm.cart = [] ;
vm.inCookie =[];
$http.get('products.xml').success(function(data) {
vm.products = data;
for (var i = 0; i < vm.products.length; i++) {
vm.products[i].id = parseInt(vm.products[i].id);
vm.products[i].netto = vm.products[i].netto + '.00';
vm.products[i].tax = parseInt(vm.products[i].tax);
vm.products[i].brutto = parseFloat(vm.products[i].brutto);
vm.products[i].rating = parseInt(vm.products[i].rating);
};
});
this.addProduct = function(row) {
vm.cart.push(row);
$cookies.put('cart', JSON.stringify(vm.cart));
vm.inCookie = JSON.parse($cookies.get('cart'));
};
}
您可以在此处查看如何从Cookie中添加和检索数据。
在这个plunkr你可以看到它工作。
