Question

i’m new to html5 web storage

setting to a web storage is easy.

sessionStorage.someKey = 'someValue';

but when i setting a array or object to a key like

sessionStorage.name = ['abc','def'];
typeof sessionStorage.name;
//output "string"
//a object is the same

so how to use array or object in web storage? or there is a better way to solve this?

I have used data structure in the past like this by using JSON. Here is a sample…

var data = { First: "abc", Second: "def" };
var jsData = JSON.stringify(data);
window.sessionStorage.setItem("key1", jsData);

Then you can get the data like so…

var jsData = window.sessionStorage.getItem("key1");
var data = JSON.parse(jsData);
