微信小程序(uni-app,js)倒计时

放入时间戳即可

// 倒计时
function timeStamp(times) {
	var timestamp = Date.parse(new Date());
	timestamp = timestamp / 1000;
	var letime = times - timestamp;
	var time = parseInt(letime);
	if (parseInt(letime) > 60) {
		var second = parseInt(letime) % 60;
		var min = parseInt(letime / 60);
		time = min + "分" + second + "秒";
		if (min > 60) {
			min = parseInt(letime / 60) % 60;
			var hour = parseInt(parseInt(letime / 60) / 60);
			time = hour + "时" + min + "分" + second + "秒";
			if (hour >= 24) {
				hour = parseInt(parseInt(letime / 60) / 60) % 24;
				var day = parseInt(parseInt(parseInt(letime / 60) / 60) / 24);
				time = day + "天" + hour + "时" + min + "分" + second + "秒";
			}
		}
	}
	return time;
}

调用的时候

           setInterval(function() {
			//定时器调用
			}, 1000)
