安装

npm i countdowntime

使用

var countdowntime = require("countdowntime"); //假设结束时间为endTime var endTime = new Date().getTime() + 30000; //倒计时结束时回调 var endCb = function(){ console.log("countDown is END!") } //倒计时进行中每秒钟执行一次回调，接收当前所剩具体时间 var timeCb = function(time){ console.log(time) } //开始执行倒计时 countdowntime.getCountDownTime(now,timeCb,endCb);

说明

var countdowntime = require("countdowntime"); console.log(countdowntime) 打印信息为: { formatNumber: [Function: formatNumber], getRemainTime: [Function: getRemainTime], getCountDownTime: [Function: getCountDownTime] } formatNumber--单位数字补零 getRemainTime--获取剩余时间明细 getCountDownTime--开始倒计时
