AngularJS local storage - initialize app retrieving local-stored data - angularjs

Question

I'm pretty new to angular and I'm trying to avoid losing items added on a simple cart application when the user refreshes the page.
I'm using angularLocalStorage (https://github.com/agrublev/angularLocalStorage) but don't know how to retrieve it back the content.
My lines:
var myApp = angular.module('ionicApp', ['ionic','angularLocalStorage']);
myApp.factory('prodottiData', function($http) {
return {
getFooOldSchool: function(callback) {
$http.get('http://192.168.1.128/hongkongapp/?json=get_recent_posts&post_type=product&custom_fields=all').success(callback);
}
}
});
myApp.factory('DataService', function() {
var myCart = new shoppingCart("AngularStore");
return {
cart : myCart
};
});
myApp.controller('MyController', function MyController ($scope, storage, $ionicSideMenuDelegate, prodottiData, DataService, $sce) {
$scope.toggleLeft = function() {
$ionicSideMenuDelegate.$getByHandle('mainMenu').toggleLeft();
};
$scope.toggleMySecondMenuLeft = function() {
$ionicSideMenuDelegate.$getByHandle('mySecondMenu').toggleLeft();
};
//adding menu data to the scope object
prodottiData.getFooOldSchool(function(data) {
$scope.menu = data;
});
//adding the cart to the scope object
$scope.cart = DataService.cart;
$scope.to_trusted = function(html_code) {
return $sce.trustAsHtml(html_code);
}
images = $scope.menu;
$scope.showloader = function(){
$scope.shownImage = this.post.thumbnail_images.full.url;
$scope.itemDesc = this.post.content;
$scope.itemPrice = this.post.custom_fields._price[0];
$scope.productName = this.post.title;
$scope.skuProdotto = this.post.id;
}
});
Now, if I check local storage on the console I can see something is really stored, but I miss the way to re-populate the cart at startup.
Any help would be great!

Answer 1

why not just using browser local storage ?
you can add it to your services.js as a new service and just used that.
var storeService = myAppServices.factory('storeService', function() {
var service =
{
setClientData:function(client_details)
{
window.localStorage.setItem( "client_data", JSON.stringify(client_details) );
client_data = client_details;
},
getClientData:function()
{
if (client_data == null)
{
client_data = JSON.parse(window.localStorage.getItem("client_data"));
}
return client_data;
}
}
var client_data = null;
return service;
});

From the documentation, to retrieve, it's storage.get('key')
So, to check after refresh:
if (storage.get('someKey')){
$scope.retrieved_value = storage.get('someKey');
}else{
// whatever
}

You can use localStorage instead windows.localStorage.
if(typeof(Storage)!=="undefined")
{
// Code for localStorage/sessionStorage.
var hello = "Hello World!!";
localStorage.setItem("hello",hello);
// get string
console.log(localStorage.getItem("hello")); // will return 'Hello World!!'
var me = {name:'abel',age:26,gender:'male'};
localStorage.setItem("user", JSON.stringify(me));
//fetch object
console.log(localStorage.getItem("user")); // will return {"name":"myname","age":99,"gender":"myGender"}
var objetos = JSON.parse(localStorage.getItem("user"));
console.log(objetos.name);
}
else
{
// Sorry! No Web Storage support..
}
