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 ipairs(tblAlphabet) do

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 } 您可以创建一个包含变量的表.
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)访问变量.
