It's an Angular Factory with $fakeStorage fallback. LocalStorage is not working in Safari, then we create a session storage in a local variable. Take care about the data you save on it, remember that it's a local variable.
angular.module('myApp.factories', [])
.factory('$fakeStorage', [
function(){
function FakeStorage() {};
FakeStorage.prototype.setItem = function (key, value) {
this[key] = value;
};
FakeStorage.prototype.getItem = function (key) {
return typeof this[key] == 'undefined' ? null : this[key];
}
FakeStorage.prototype.removeItem = function (key) {
this[key] = undefined;
};
FakeStorage.prototype.clear = function(){
for (var key in this) {
if( this.hasOwnProperty(key) )
{
this.removeItem(key);
}
}
};
FakeStorage.prototype.key = function(index){
return Object.keys(this)[index];
};
return new FakeStorage();
}
])
.factory('$localstorage', [
'$window', '$fakeStorage',
function($window, $fakeStorage) {
function isStorageSupported(storageName)
{
var testKey = 'test',
storage = $window[storageName];
try
{
storage.setItem(testKey, '1');
storage.removeItem(testKey);
return true;
}
catch (error)
{
return false;
}
}
var storage = isStorageSupported('localStorage') ? $window.localStorage : $fakeStorage;
return {
set: function(key, value) {
storage.setItem(key, value);
},
get: function(key, defaultValue) {
return storage.getItem(key) || defaultValue;
},
setObject: function(key, value) {
storage.setItem(key, JSON.stringify(value));
},
getObject: function(key) {
return JSON.parse(storage.getItem(key) || '{}');
},
remove: function(key){
storage.removeItem(key);
},
clear: function() {
storage.clear();
},
key: function(index){
storage.key(index);
}
}
}
]);
