所有属性的 JavaScript getter
JavaScript 是否提供访问未定义对象属性的方法?在 PHP 中,解决方案是在类中声明并实现 __get()
方法.
使用 try { .. } catch { .. }
的解决方案对我来说是不够的,因为我已经有大量的代码实际上需要保持原样.
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.
您可以选择编写一个类似的功能并根据 参数 数组.我不是 100% 认为这会解决您的问题.
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.
