arrays - Lua根据数组元素检查值

试图自学Lua；我已经经历过类似的问题，但我仍然不明白该怎么做。使我感到困惑的主要是表与数组。对于下面的代码，我只想对照已填充到数组中的值检查给定值。但是，出了点问题。谢谢你的时间

valueToCheckFor = 35

sampleArray = {}
for i=30, 49, 1  do
  sampleArray[i] = i + 1
  print(i)
end

for k = 0, #sampleArray, 1 do
    if valueToCheckFor == k then
        print(valueToCheckFor .. " is in the array.")
    else
        print(valueToCheckFor .. " is not in the array.")
    end
end

最佳答案

这是编写对Lua数组友好的代码：

valueToCheckFor = 35

sampleArray = {}
for i=30, 49  do
    -- add to end of array
    sampleArray[#sampleArray+1] = i + 1
    print(i+1)
end

-- check each value in array
for k = 1, #sampleArray do
    if valueToCheckFor == sampleArray[k] then
        print(valueToCheckFor .. " is in the array.")
    else
        print(valueToCheckFor .. " is not in the array.")
    end
end
