检查对象的继承属性 [英] inspect inherited properties of an object

问题描述

如何检查继承到对象的对象的属性?我不能使用Object.keys和Object.getOwnPropertyNames！

Object.keys :此方法返回由给定对象定义的所有可枚举属性名称的数组(inherited properties are not considered)

Object.getOwnPropertyNames :类似于Object.keys(obj)，但另外返回不可枚举属性的名称(again, inherited properties are not included).

how inspect the properties of an object where inherited to object?i can''t use of Object.keys and Object.getOwnPropertyNames !

Object.keys:This method returns an array of all enumerable property names defined by a given object (inherited properties are not considered)

Object.getOwnPropertyNames:similar to Object.keys(obj) but additionally returns the names of non-enumerable properties (again, inherited properties are not included).

var f = new Object();
        f.l = 8;

        Object.prototype.s = 9;

        Object.defineProperty(Object.prototype, "constvar", {
            enumerable: false,
            value: 88
        });

        var g1 = Object.keys(Object);
        var gg1 = Object.getOwnPropertyNames(Object); //don't contain 'constvar' where is not enumerable but exist s property where is enumerable

推荐答案

您可以从类的基本类型中获取这些属性.要获取基本类型:SomeObject.GetType().BaseType

祝你好运！

You can get those properties from the base type of a class. To get the base type: SomeObject.GetType().BaseType

Good luck!
