Turning JSON strings into objects with methods

Question

I have an app that allows users to generate objects, and store them (in a MySQL table, as strings) for later use. The object could be :

function Obj() {
             


        

Answer 1

Try to use toString on the method.

Update:

Iterate over the methods in obj and store them as string, and then instantiate them with new Function.

storedFunc = Obj.prototype.setLabel.toString();
Obj2.prototype['setLabel'] = new Function("return (" + storedFunc + ")")();
