本文实例讲述了JS基于面向对象实现的多个倒计时器功能。分享给大家供大家参考,具体如下:

运行效果图如下:

实现代码如下:

//名山计时器:

 this._minute=0;   //“分”数
 this._seconds=0;  //“秒”数
 //

 //1.获取对象
 $:function(ID){
  return document.getElementById(ID);
 },
 //2.初始化:
 /*
  * arrTime:  传入时间数组,格式为[1,30,30],代表 1小时30分30秒;
  * arrHtmlObj: 更新时间数据的Html对象数组,格式为["hour","minute","seconds"];

  _this._totalSeconds=parseInt(_this._hour*60*60+_this._minute*60+_this._seconds);
  //开始计时:
  _this.timeCount();

 //3.计时器:

  var tmpTimeCount=setInterval(
   function(){
    _this._totalSeconds--;

 //4.刷新页面时间:

   _this._minute=parseInt((_this._totalSeconds-_this._hour*3600)/60);

  }else{
   _this._hour=_this._minute=_this._seconds=0;
  }
  _this._hourHtmlObj.innerHTML=_this._hour;
  _this._minuteHtmlObj.innerHTML=_this._minute;
  _this._secondsHtmlObj.innerHTML=_this._seconds;

var timeCount1=new msTimeCount();
