function time(){
var EndTime = new Date('2017/04/26 00:00:00');
var NowTime = new Date();
var t = EndTime.getTime() - NowTime.getTime();
var d = 0;
var h = 0;
var m = 0;
var s = 0;
if(t >= 0){
d = parseInt(t/1000/60/60/24);
h = parseInt(t/1000/60/60%24);
m = parseInt(t/1000/60%60);
s = parseInt(t/1000%60);
}
times[0].innerHTML = d + '天';
times[1].innerHTML = h + '时';
times[2].innerHTML = m + '分';
times[3].innerHTML = s + '秒';
}
setInterval(time,1000);
