JavaScript must Know (Seven) JS object inheritance _ Basic knowledge

Object inheritance Inherit

var o = {r:};
var c = function f () {
};
C.prototype = O;
C.R =;
Alert (O.R)//The inherited property value has not changed.
alert (C.R);//c in R overwrites the properties in O.

How do I call the R property in O?

var o = {r:};
var c = function f () {
};
C.prototype = O;
Alert (O.R)//The inherited property value has not changed.
alert (C.R);//Query R property, return undefined value.

Calls should be made using prototypes.
