我如何在表中找到特定的值？

Question

例如，我有下表：

Vehiclecache[1]='00000028376'
Vehiclecache[2]='00000036357'
Vehiclecache[3]='00000067453'

每个表都有车辆模型、车牌、颜色等的值。

我有一辆带有'573D86‘车牌的汽车，我如何才能拿起这个值的钥匙来像这个VehiclecacheKey那样使用它

Answer 1

这就是你要找的吗？

-- vehicle table
vehicle_cache = {}
vehicle_cache[1] = {
    name = "car_1",
    plate = "BD51 HYU",
    color = { 1, 1, 1 }
}

vehicle_cache[2] = {
    name = "car_2",
    plate = "NU71 DHA",
    color = { 1, 1, 1 }
}

-- function to find the vehicle via plate
local function find_from_plate(plate)
    local vehicle = nil
    
    for _, veh in ipairs(vehicle_cache) do
        if veh.plate == plate then
            vehicle = veh
            break
        end
    end
    
    return vehicle
end

-- find a vehicle and print the name
local vehicle = find_from_plate("NU71 DHA")
if vehicle then
    print("vehicle: " .. vehicle.name) 
end
