问题描述

我是 Lua 新手，遇到了一些困难:

I am new to Lua and am having some difficulties:

我正在尝试创建动态变量名称:

I am trying to create dynamic variable names:

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

  }

推荐答案

您可以创建一个包含变量的表.

You can create a table which contains your variables.

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 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vars.

Then you can access vars via iterators or direct access (vars.a_button).
