存在这样一个需求，一批订单包含未完成订单(含有倒计时提示)，这里有知友关于VueJs的建议：

vue 列表循环倒计时（https://www.zhihu.com/question/47746149）。

请问怎样实现上图效果？

function countDifftime(){
    var self = this;
    var orderList = self.data.orderList;
    var i = 0;
    var length = orderList.length;
    for(; i < length; i++){
        if(orderList[i].Status == 1){
            var difftimer = setInterval(function(){
                console.log(self.data.orderList[0].difftime);
                console.log(self.data.orderList[i].difftime);
                var oDifftime = orderList[i].difftime.split(":");
                var h = Math.floor(difftime / 60 / 60);
                var min = Math.floor(difftime / 60 % 60);
                var sec = Math.floor(difftime % 60);
                var sDifftime = "";
                if(h <= 0 && min <= 0 && sec <= 0){
                    clearInterval(difftimer);
                    self.onShow();
                }else{
                    sDifftime = common.formatNumber(h) + ":" + common.formatNumber(min) + ":" + common.formatNumber(sec);
                    orderList[i].difftime = sDifftime;
                    console.log("--------------" + JSON.stringify(self.data.orderList) + "--------------");
                    sec--;
                    if(sec < 0){
                        sec = 59;
                        min--;
                        if(min < 0){
                            min = 59;
                            h--;
                        }
                    }
                }
                self.setData({
                    "orderList": orderList
                });
            }, 1000);
        }
    }
}
