确定 JavaScript 属性是否定义了 getter 或 setter? [英] Determine if a JavaScript property has a getter or setter defined?

问题描述

是否有可能通过给定一个对象和属性名称来确定该属性是使用 getter 还是 setter 定义的，还是完全透明的?如果属性上尚未定义 getter/setter，我只想定义一个 getter/setter.

Is it possible, given an object and property name to determine if that property is defined using either a getter or setter, or is it completely transparent? I only want to define a getter/setter if there is not already one defined on the property.

我需要它在 WebKit/Firefox 中工作.
