JavaScript 相当于 PHP 的 __get() 魔法方法

2022-01-04 00:00:00 properties undefined get php javascript

可能的重复:
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.

推荐答案

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.
