我是Lua的新手,遇到了一些困难：

我正在尝试创建动态变量名称：

local tblAlphabet = {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"};

local count = 0;

for k,v in pairs (tblAlphabet) do

  count = count + 1;

  [v.."button"]  = ui.newButton{ --HOW DO I MAKE THIS WORK? I get syntax error

--some code here

  }

解决方法

您可以创建一个包含变量的表.

local tblAlphabet = {"a","z"}
local vars = {}
for k,v in pairs(tblAlphabet) do
    vars[v .. "_button"] = ui.newButton()
end

然后,您可以通过迭代器或直接访问(vars.a_button)访问变量.
