屏幕休眠或后台运行倒计时暂停问题

 updateTime: function () {let promise = new Promise((resolve, reject) => {var beginTime = new Date().getTime();let setTimer = setInterval(() => {var newTime = new Date().getTime();var dTime = (newTime - beginTime) / 1000;dTime = parseInt(dTime);this.setData({time: 60 - dTime})if (this.data.time <= 0) {this.setData({time: 60,yzmStep: 3,})resolve(setTimer)}}, 1000)})promise.then((setTimer) => {clearInterval(setTimer)})},
