微信小程序倒计时实现功能
onLoad: function () {
var that=this;
this.data.intervarID= setInterval(function () {
var leftTime = (new Date(2017, 6-1, 28, 17, 40, 0)) - (new Date()); //计算剩余的毫秒数
var days = parseInt(leftTime / 1000 / 60 / 60 / 24, 10); //计算剩余的天数
var hours = parseInt(leftTime / 1000 / 60 / 60 % 24, 10); //计算剩余的小时
var minutes = parseInt(leftTime / 1000 / 60 % 60, 10);//计算剩余的分钟
var seconds = parseInt(leftTime / 1000 % 60, 10);//计算剩余的秒数
days = checkTime(days);
hours = checkTime(hours);
minutes = checkTime(minutes);
seconds = checkTime(seconds);
that.setData({
clock: days + "天" + hours + "小时" + minutes + "分" + seconds + "秒"
})
if (days == '00' && hours == '00' && minutes == '00' && seconds=='00')
{
clearInterval(that.data.intervarID);
}
}, 1000
)
},
