vue中时间过滤器中的月日不足两位补0

先将月，和日转换为字符串，然后用字符串的padStrat(2,0)方法(两位，不足补0)

filters: {
	handleData(date) {
      const timeDate = new Date(date);
      const year = timeDate.getFullYear();
      const month = (timeDate.getMonth() + 1).toString().padStart(2, 0);
      const day = timeDate.getDate().toString().padStart(2, 0);
      const hour = timeDate.getHours().toString().padStart(2, 0);
      const min = timeDate.getMinutes().toString().padStart(2, 0);
      const s = timeDate.getSeconds().toString().padStart(2, 0);
      return year + "-" + month + "-" + day + " " + hour + ":" + min + ":" + s;
    },
		},
