Js-计算时间差

计算时间差

项目中需要倒计时效果

data(){
	return {
		data:null,
		timingDate:{
			days:'',
			hours:'',
			minutes :'',
			seconds :'',
		},
		//全局定时器对象
		//作用:页面跳转或其他需要时用于关闭定时器
		serverTimeOut:null
	}
}
methods:{
    //计算时间差
    getTimingDate(endDate) {
      //endDate作为一个变量传进来
      //如果时间格式是正确的，那下面这一步转化时间格式就可以不用了
      var dateEnd = new Date(endDate.replace(/-/g, "/")); //将-转化为/，使用new Date
      var dateBegin = new Date(); //获取当前时间
      var dateDiff = dateEnd.getTime() - dateBegin.getTime(); //时间差的毫秒数
      var dayDiff = Math.floor(dateDiff / (24 * 3600 * 1000)); //计算出相差天数
      var leave1 = dateDiff % (24 * 3600 * 1000); //计算天数后剩余的毫秒数
      var hours = Math.floor(leave1 / (3600 * 1000)); //计算出小时数
      //计算相差分钟数
      var leave2 = leave1 % (3600 * 1000); //计算小时数后剩余的毫秒数
      var minutes = Math.floor(leave2 / (60 * 1000)); //计算相差分钟数
      //计算相差秒数
      var leave3 = leave2 % (60 * 1000); //计算分钟数后剩余的毫秒数
      var seconds = Math.round(leave3 / 1000);
      this.timingDate.days = dayDiff < 10 ? "0" + dayDiff : dayDiff
      this.timingDate.hours = hours < 10 ? "0" + hours : hours;
      this.timingDate.minutes = minutes < 10 ? "0" + minutes : minutes;
      this.timingDate.seconds = seconds < 10 ? "0" + seconds : seconds;
    },
    
    getData() {
      let that = this;
      matchModel.getData().then(res => {
        if (res.code != 0) {
          return consolt.log('error')
        }
        this.data = res.data;

        this.serverTimeOut = setInterval(function () {
          that.getTimingDate(res.data.voteEndTime);
        }, 1000);
      })
    },
 }
