How to use JSON to stringify/parse a user-defined class [duplicate]

Parse JSON String into a Particular Object Prototype in JavaScript

So I have a class defined like

function ThisClass (a,b,c) {
    this.a = a;
    this.b = b;
    this.c = c;
}
ThisClass.prototype.a_method = function(param) {
    //stuff
}


var instance = new MyClass(a,b,c);
var stringified = JSON.stringify(instance);
var parsed = JSON.parse(stringified);

When I stringify this and store it in a database it's all cool. However, when I parse it after retrieval, it loses its class type, so when viewing it after parsing in chrome's inspect tool, the object is shown as just a regular object, like instance: Object instead of instance: MyClass.

Because of this, the newly parsed variable parsed does not have any of the prototype methods associated with it at instantiation. Any know how to do this, or if I'm doing it wrong?

Thanks!

You can not, JSON is only meant to be used to serialize non circular data object variable.

This the spec for more détails.
