var myClock = {
            getSecondDeg : function (){

                var now_seconds = time.getSeconds();

                var _deg = now_minutes * 6 + now_seconds/10

                var hour_p = document.createElement("div");
                hour_p.id = "hour";
                //分针
                var minutes_p = document.createElement("div");
                minutes_p.id = "minutes";
                //秒针

                clock_c.appendChild(hour_p);
                clock_c.appendChild(minutes_p);
                clock_c.appendChild(second_p);
                myClock.refush(hour_p,minutes_p,second_p);
                setInterval(function(){
                    myClock.refush(hour_p,minutes_p,second_p);
                },1000);
            },
            refush : function(hh,mm,ss){
                hh.style.transform = 'rotateZ('+ myClock.getHourDeg() +'deg)';
                mm.style.transform = 'rotateZ('+ myClock.getMinuteDeg() +'deg)';
                ss.style.transform = 'rotateZ('+ (myClock.getSecondDeg()+1) +'deg)';
                setTimeout(function(){
                    ss.style.transform = 'rotateZ('+ myClock.getSecondDeg() +'deg)';
                }, 50);
            }

        }

        var clock = document.getElementById("clock")

        myClock.init(clock);

我想将 myClock.init(clock) 改成 clock.myClock.init() 这样的方式调用。

还有只允许 myClock中的 Init()方法能被外部调用，其他方法为私有方法，改如何写。

 

 //我刚开始这样写的会报错
var clock = function(){
    init = function(element){

    }

    //....

    return init;
}
