我正在使用Ionic Framework构建应用程序，所有数据主要存储在parse.com上。我想用户能够离线保存一些数据，所以我正在编写以下函数来实现：
$scope.doSaveRow = function (_index) {
console.log(_index);
ParseRecipeService.get(_index).then(function (_data) {
$timeout($scope.recipeItem = _data, 0);
}, function (_error) {
console.error(_error.message);
});
console.log(JSON.stringify($scope.recipeItem));
};
这是控制台输出：

现在我可以从控制台打印输出看到我的所有数据都在$ scope.recipeItem变量中，但我不知道如何访问存储在描述下的信息。如何将该信息放入变量中？如何离线保存该信息？
