How to put Objects on HTML5 sessionStorage/localStorage

HTML5 sessionStorage and localStorage only allows you to store strings, but sometimes it’s very convenient to add more complex values like arrays and objects. Here a simple way to do that:

var array = [];
// Put object on sessionStorage
sessionStorage.setItem('key', JSON.stringfy(array));
// Get object from sessionStorage
var object = JSON.parse(sessionStorage.getItem('key'));

As you can see in the example I’ve just converted my array to a string before storing it in the sessionStorage, then I converted it back to an array when I retrieved it from the sessionStorage. This was a very simple workaraound, hope it helps!
