[记录] javascript 对象中使用setTimeout

参考:Javascript对象中关于setTimeout和setInterval的this介绍

使用最后一个方法终于弄好了，简直了，在对象中使用setTimeout原来是这样的

做的是分钟倒计时，倒数3分钟

function clock(){

    this.min    = 3; //倒数的分钟
    this.speed  = 1000; //setTimeout时间
    var timeId  = ""; //保存setTimeout对象
    this.time   = this.min * 60;//3分钟等于180s
    this.move   = function(){
        var that    = this;//保存当前对象this 
        this.time   = parseInt(that.time);
        var minute  = 0; //分
        var seconds = 0; //秒
        

        if(this.time > 60){
            minute  = parseInt(that.time / 60);
            seconds = parseInt(that.time % 60);
        }else{
            minute  = 0;
            seconds = parseInt(that.time % 60)
        }
        
        

        var txt     = ((minute < 10) ? "0" + minute : minute) + " : " + ((seconds < 10) ? "0" + seconds : seconds);

        timeId      = setTimeout(function(){
            that.move();
        },that.speed);

        console.log(that.time);
        that.time--;
        console.log(txt);
        
        if(that.time <= 0){
            clearTimeout(timeId);
        };
    },
    this.stop = function(){
       clearTimeout(timeId); 
    }    
}

 使用:

var eva3_clock = new clock();
    eva3_clock.move();
