4.倒计时
document.getElementById 获得时间戳
var endTime = new Date("2018-09-07 18:00:00");
var curTime = new Date();
var times = endTime.getTime() - curTime.getTime(); console.info(times) var year = times / 1000 / 3600 / 24;
var hours = year % 1 * 24; console.info(hours)
var min = hours % 1 * 60;
console.info(min) var s = min % 1 * 60;
console.info(s)
通过所得时间戳计算时间倒计时
