Displaying JSON object from local storage in Alert window

[RobertJay]

This is not a big deal, but I was wondering how a JSON object being stored in local storage can be viewed in an alert box. When I display it, there is nothing which shows other than a bottom scroll bar as shown below. String values display fine. Thanks.

Hi Robert,

How do you do this?

Hi Robert,

LocalStorage Name/value pairs are always stored as strings.
If you write correct JSON string in localStorage, you won't have any problem.
Try this simple test for working with locaStorage:
prevar obj = {x: 5, y: 6};
var s = JSON.stringify(obj);
localStorage.setItem("test",s);
var r = localStorage.getItem("test");
alert(r);/pre

Thanks Katya. I guess I was storing the pure object and not the string version. Question: on a service response will the variable be stored automatically in string format or do I have to do the stringify first?

Hello Robert,

On service response variables will be stored in local storage in string format automatically.
