1.传入一个结束时间 eg：'2018-12-01 00:00:00'
var timer = null;
function time(that, time, cd) {
console.log("当前时间", time)
clearInterval(timer);
if (time == '') {
return false
}
var endTime = new Date(time).getTime() || 0,
nowTime = new Date().getTime(),
hours = 60 * 60,
minutes = 60,
lfTime = (endTime - nowTime) / 1000;
if (lfTime < 0) {
return cd()
}
timer = setInterval(function() {
lfTime--;
var Hours = Math.floor(lfTime / hours),
Minutes = Math.floor((lfTime - Hours * hours) / minutes),
Seconds = Math.floor((lfTime - Hours * hours - Minutes * minutes));
Hours = Hours < 10 ? "0" + Hours : Hours;
Minutes = Minutes < 10 ? "0" + Minutes : Minutes;
Seconds = Seconds < 10 ? "0" + Seconds : Seconds;
var time = {
hour: Hours,
min: Minutes,
second: Seconds
}
if (Hours === '00' && Minutes === "00" && Seconds === "00") {
clearInterval(timer);
cd()
}
return that.setData({
time: time
})
}, 1000)
}
module.exports = time;
2.调用方法 import timer from '/你存放的路径'
3.使用
timer(this, '2018-12-01 00:00:00', () => {
console.log(1235567)
})
