unpack它接受一个数组(table)作为参数,并默认从下标1开始返回数组的所有元素,例子代码如下:

复制代码 代码如下:

do
 arrayData = {"a", "b", "c", "d", "e"};

 

 function returnMoreValues()
  return 1, 2, 3;
 end

 a, b, c = returnMoreValues();

 --print(a, b, c);

 --print((returnMoreValues()));

 --print(arrayData); -- print the address of the arrayData
 --print(unpack(arrayData)); -- print all the elements of the arrayData
 print(unpack(arrayData, 2)); --the second param is the index of the arrayData

end
