javascript - 是否可以在javascript中解析对象的所有公共(public)变量？

Question

假设我有一个包含一组公共(public)变量和私有(private)变量的对象

function myObj()
{
    var private1 = 1;
    var private2 = 2;
    this.func = function(){console.log('anything');};
    this.public1 = 3;
    this.public2 = '4';
}

有没有办法创建一个可以解析对象并检索公共(public)变量的名称、值和类型的函数。

这个函数的原型(prototype)是:

parseObj(object)

控制台结果将是:

>object has public1 with value 3 of type Number
>object has public2 with value 4 of type String

您可以使用 for in 循环轻松创建这样的函数:

function parseObj(object) {
    for(var name in object) {
        if(object.hasOwnProperty(name)) {
            // ignoring methods
            if(typeof object[name] !== 'function') {
                console.log('object has '+name+' with value '+object[name]+' of type '+typeof object[name]);
            }
        }
    }
}
