活动倒计时脚本 - 《代码人生》

下面的源码是这个当天 9:30 ~ 10:30 的活动展示的倒计时读秒 ``` var nowDate = $(‘#now_date1’).val();//服务器当前时间

//活动倒计时 this.countdown = function () { var djsdom = $(‘#countdown’); if (djsdom.length > 0) { var start = new Date(nowDate); start.setHours(9, 30, 00); var end = new Date(nowDate); end.setHours(10, 30, 00); var f; var now = new Date(nowDate); f = setInterval(function () { if (now >= start && now <= end) { now.setTime(now.getTime() + 1000); //循环加1秒 var _times = end - now; var _min = (parseInt(_times / 1000 / 60 % 60)).toString(); var _s = (parseInt(_times / 1000 % 60)).toString(); if (_min.length == 1) { _min = ‘0’ + _min; } if (_s.length == 1) { _s = ‘0’ + _s; } //console.log(_min + ‘\n’ + _s); djsdom.html(‘

‘ + _min.substring(0, 1) + ‘‘ + _min.substring(1) + ‘‘ + _s.substring(0, 1) + ‘‘ + _s.substring(1) + ‘

‘); } else { clearInterval(f); djsdom.html(‘’); } }, 1000);

    };
};

```
