遍历数组下标table

使用for循环遍历

t= {"a","b","c","d"}
for i =1,#t do
	print(i,t[i])
end

执行结果

使用ipars遍历

t = { "a", "b", "c", "d" }
for i, j in ipairs(t) do
    print(i, j)
end

i代表数字下标
j代表i下标中的元素
执行结果

遍历字符串下标table

使用pars遍历

t = {
    apple = "a",
    banana = "b"
}
for i, j in pairs(t) do
    print(i, j)
end

执行结果

next函数

t = {
    apple = "a",
    banana = "b"
}
print(next(t))
print(next(t, "apple"))
print(next(t, "banana"))
