小程序对mongodb日期显示处理问题

  //处理日期
  changeDateFormat: function (cellval){
    var dateVal = cellval + "";
    if (cellval != null) {
      var date = new Date(parseInt(dateVal.replace("/Date(", "").replace(")/", ""), 10));
      var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
      var currentDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();

      var hours = date.getHours() < 10 ? "0" + date.getHours() : date.getHours();
      var minutes = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes();
      var seconds = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds();

      return date.getFullYear() + "-" + month + "-" + currentDate + " " + hours + ":" + minutes + ":" + seconds;
    }
  },

    // var dd = "/Date(1584538219495)/"
    // var mm = this.changeDateFormat(dd);
    // console.log(mm);
