Deserializing JavaScript object instance

Question

I am working on an app that heavily uses JavaScript. I am attempting to include some object-oriented practices. In this attempt, I have created a basic class like such:

You can only store plain Objects in DOMstorages (cookies, urlparams..., everything that needs [de]serialisation through JSON.stringify/JSON.parse). So what you did when sending the ajax data

ajaxsend(this.data);

also applies to string serialisation. You can only store the data, not the instance attributes (like prototype, constructor etc.). So use

savestring(JSON.stringify(item.data));

which is possible because item.data is such a plain Object. And when restoring it, you will only get that plain data Object back. In your case it's easy to reconstruct a Item instance from plain data, because your Items hold their values (only) in a public available property:

var item = new Item;
item.data = JSON.parse(getjsonstring());
