在虚拟获取器中添加参数

问题描述

我想做的是这样的:

Schema
.virtual('getSomething')
.get(function(what) {
    if (!what) {
        return this.somethingElse
    } else {
        return this.something[what]
    }
})

问题是我们不能在虚拟的getter中传递参数，如何在不重复代码的情况下实现类似的目的?

The problem is that we can't pass arguments in a virtual getter, how can I achieve something like that without having to duplicate my code ?

推荐答案

将其添加为实例方法而不是虚拟的获取器.

Add it as an instance method instead of a virtual getter.

schema.methods.getSomething = function(what) {
    if (!what) {
        return this.somethingElse
    } else {
        return this.something[what]
    }
};
