JavaScript等价于PHP的__get（）魔术方法 [英] JavaScript's equivalent to PHP's __get() magic method

问题描述

可能存在重复：

所有属性的JavaScript getter

JavaScript是否提供方法访问未定义的对象属性？在PHP中，解决方案是在类中声明和实现 __ get（）方法。 {...} 对我来说是不够的，因为我已经有非常多的代码需要保持原样。

>解决方案

您可以选择编写类似的功能，并根据参数数组。我不是100％，这将解决您的问题。

Does JavaScript provide a method to access undefined object properties? In PHP the solution is to declare and implement __get() method in class.
Solutions using try { .. } catch { .. } are not sufficient for me, because I already have very large amount of code which actually needs to stay as-is.

解决方案

You may choose to write a similar functionality and check existing parameters them against the arguments array. I'm not 100% that this will solve your problem.
