Issue encountered in AngularJS: struggling to store the localStorage item in the scope variable

I've been trying to save the values from 

window.localStorage.getItem('job_id.done_tasks')
into a $scope variable, but I'm encountering difficulties. Can you please review my code?

$scope.done_tasks = {};
$scope.done_tasks = window.localStorage.getItem('job_id.done_tasks');

When I try to alert('$scope.done_tasks');, it returns undefined. However, if I use 

alert(window.localStorage.getItem('job_id.done_tasks'));
, it displays 16,17. I am unsure why I am unable to store the values of 
window.localStorage.getItem('job_id.done_tasks')
in $scope.done_tasks. Any help with this would be appreciated.

Answer №1

If you take a look at the code below, you'll see that local storage is returning a string as its output. To work with this data effectively, you will need to parse it into an object.

$scope.completed_tasks = JSON.parse(window.localStorage.getItem('task_id.completed_tasks'));

Just a reminder:

window.localStorage.setItem(key,value);
window.localStorage.getItem(key);

Local storage operates on a key-value system, meaning that you must use the same key when saving and retrieving data.
