2019-01-07实现时分秒倒计时

传入一个秒数返回一个数组(0补位)

function cutdown(time){
            let timearr = [];
            let hours0 = ~~time/36000)>0? ~~(this.time/36000) : 0;
            timearr.push(hours0);
            let hours1 = ~~(time/3600)%10>0? ~~(time/3600)%10 : 0;
            timearr.push(hours1);
            let minutes0 = ~~(time%3600/600)>0?~~(time%3600/600) : 0;
            timearr.push(minutes0);
            let minutes1 = ~~(time%3600/60)%10>0?~~(time%3600/60)%10 : 0;
            timearr.push(minutes1);
            let sec = ~~(time%3600%60/10)>0?~~(time%3600%60/10) : 0;
            timearr.push(sec);
            let sec1 = time%3600%60%10;
            timearr.push(sec1);
            return timearr ;
}
