LUA简单迭代循环。

local one_ = {1,200,300,004,50,6,-1};
for count,number in pairs(one_) do
	print("number = "..number..",count="..count);
end

其中count为元素值，number为元素的下标值。

function iterator(it)
	local num = 0;
	return function()
		num = num + 1;
		return it[num];
	end
end

local two_ = {"youkuaiyun.com","123"}
for value in iterator(two_) do
	print(value);
end
