JS代码(得到后台数据查询用FIND方法插入字段,直接遍历会有问题)

mpThing.find(function(v){
        var aa = v.goods_time;
        var bb = util.dayTimeArr(aa);
        v.goods_time = bb
        that.setData({
         mpThing:mpThing,
        })
        var ref = setInterval(function(){
          aa--
          var timeArr = util.dayTimeArr(aa);
          v.goods_time = timeArr
          that.setData({
           mpThing:mpThing,
          })
        },1000);
