Using JSON.stringify on custom class

Question

I\'m trying to store an object in redis, which is an instance of a class, and thus has functions, here\'s an example:

function myClass(){
    this._attr = \"         


        

Answer 1

What you get back grom JSON.stringify() is a String. A string has no methods. You need to eval first that string and then you'll be able to get the original object and its methods.

var myObj = new myClass();
var stringObj = JSON.stringify(myObj);

---- EDIT -----

//Sorry use this:
var getBackObj  = JSON.parse(stringObj);
//Not this
var getBackObj = eval(stringObj);

console.log(getBackObj.getAttr()); // this should work now
