Question

var hot = {
    loca: function ($url) {
        msg: function ($url) {
            console.log($url)
        }
    }
}

hot.loca.msg('http://baidu');

为什么这样子运行不了 不能在里面再套一层吗

有什么办法能让 hot.loca.msg('http://baidu'); 打印到控制台吗

var hot = {
    loca: {
        msg: function ($url) {
            console.log($url)
        }
    }
}

hot.loca.msg('嘤嘤嘤')

var hot = {
    loca: function($url) {
        return {
            msg: function($url) {
                console.log($url)
            }
        }
    }
}

hot.loca('嘤嘤嘤').msg('嘤嘤嘤')
