The json.parse () static method parses a json string, constructing the javascript value or object described by the string. an optional reviver function can be provided to perform a transformation on the resulting object before it is returned. 2 json.stringify() seems to do exactly what you need. it will remove all functions and all undefined variables. a = { b : undefined , c : 'inited'}; json.stringify( a ) will return '{"c":"inited"}' if you need the object itself, you can json.parse the resulting string to go back to a clean object. By following these steps, you should be able to resolve the undefined issue and access your json object's properties successfully.
