Question

因此，分配是根据车辆类型分配停车位。如果是2轮摩托车-摩托车现货，4轮摩托车-紧凑型和大型现货，公共汽车-5个大型现货

我需要一种优化方法来获得可用的停车位，即。 slot.occupied == false，并且我想避免多个for循环，因为数据将增加并且具有多个级别。

    "levelNo":"1",
    "row":{[
        "rowNo":"1",
        "slots":[{
            "slotNo":1,
            "slotType":"Motorcycle",
            "occupied":false
            },
            {
            "slotNo":2,
            "slotType":"Motorcycle",
            "occupied":false
            },
            {
            "slotNo":3,
            "slotType":"Motorcycle",
            "occupied":false
            },{
            "slotNo":4,
            "slotType":"Compact",
            "occupied":false
            },{
            "slotNo":5,
            "slotType":"Compact",
            "occupied":false
            },{
            "slotNo":6,
            "slotType":"Compact",
            "occupied":false
            },
            {
            "slotNo":7,
            "slotType":"Large",
            "occupied":false
            },
            {
            "slotNo":8,
            "slotType":"Large",
            "occupied":false
            }]
        },
        {
        "rowNo":"2",
        "slots":[{
            "slotNo":1,
            "slotType":"Motorcycle",
            "occupied":false
            },
            {
            "slotNo":2,
            "slotType":"Motorcycle",
            "occupied":false
            },
            {
            "slotNo":3,
            "slotType":"Motorcycle",
            "occupied":false
            },{
            "slotNo":4,
            "slotType":"Compact",
            "occupied":false
            },{
            "slotNo":5,
            "slotType":"Compact",
            "occupied":false
            },{
            "slotNo":6,
            "slotType":"Compact",
            "occupied":false
            },
            {
            "slotNo":7,
            "slotType":"Large",
            "occupied":false
            },
            {
            "slotNo":8,
            "slotType":"Large",
            "occupied":false
            }]

        }]

}

也许您可以创建一个变量来存储搜索停车位的车辆类型。然后，您只需要一个for循环，即可搜索同样未被占用的停车位。您无需循环每个楼层，循环遍历所有停车位，并且在找到停车位时便会显示出停车位编号及其所在的楼层。

代替存储每个级别的数据。仅制作一个停车位模型，并在其中显示其所在的高度。因此，该模型将类似于：

spotNumber: {
  occupied: false,
  type: "large",
  level: 1
}
