起码弄个代码片段

setCountDown: function () {
        var thisPage = this
        var Pause = thisPage.data.isPause
        
        if (Pause == false) {
            //刷新时间以及递减时间范围
            let time = 1000;
            let wPause = thisPage.data.wasPause
            let test = thisPage.data.pingData[0].time
            var Text = thisPage.data.showText
            let {
                listData
            } = thisPage.data;
            
            // map里   v为当前数组操作的元素，i为当前元素在数组的坐标
            //对数组进行拆包
            let list = listData.map((v, i) => {
                if (v.time < 0) {
                    v.time = 0;
                }
                //对元素进行日期输出格式化
                let formatTime = thisPage.getFormat(v.time);
                v.time -= time;                
                v.countDown = `${formatTime.mm}:${formatTime.ss}`;
                //进行是否曾经暂停
                console.log("经过暂停前" +this.data.wasPause)
                if (wPause == true) {
                    v.time = v.time + 1000;
                    //可以赋值
                    thisPage.setData({
                        wasPause: false                        
                    })
                    console.log("first time to regoing!")
                    console.log("经过暂停后" + this.data.wasPause)
                }


                console.log(test)
                console.log(thisPage.data.pingData[0])


                if (v.time < 0) {                
                    thisPage.setData({
                        test: 0,
                        showText: "交换攻防",
                        isPause: true
                    })
                    console.log(Pause)
                    thisPage.showPopup()
                }


                return v;
            });
            
            thisPage.setData({
                listData: list
            });
            //setTimeout里  在第二个函数指定毫秒时后触发第一个函数的方法
            //现在语句意思为 =》在time=1000毫秒时，执行setCountDown方法，实则为循环
            setTimeout(thisPage.setCountDown, time);
        }
        if (Pause == true) {
            return
        }

    }

补充代码块，目前只用到了一个秒级，但还是很卡
