小程序中使用倒计时

that.data.interval = setInterval(function () {

// 秒数

var second = totalSecond;

// 天数位

var day = Math.floor(second / 3600 / 24);

// 小时位

var hr = Math.floor((second - day * 3600 * 24) / 3600);

var hrStr = hr.toString();

if (hrStr.length == 1) hrStr = '0' + hrStr;

// 分钟位

var min = Math.floor((second - day * 3600 * 24 - hr * 3600) / 60);

var minStr = min.toString();

if (minStr.length == 1) minStr = '0' + minStr;

// 秒位

var sec = second - day * 3600 * 24 - hr * 3600 - min * 60;

var secStr = sec.toString();

if (secStr.length == 1) secStr = '0' + secStr;

this.setData({

countDownDay: hrStr + ':' + minStr + ':' +secStr,

percentage: (24 - hr)/24*100

});

totalSecond--;

if (totalSecond <= 0) {

console.log(1);

clearInterval(that.data.interval);

wx.showToast({

title: '游戏已结束',

});

this.setData({

countDownDay: '已结束',

});

}

}.bind(this), 1000);

},

 

 

小程序中清除定时器

clearInterval(that.data.interval)
