初学lua，有个问题请教前辈们。

[「已注销」]

长度>=3的字符就可以运行，<3的字符就不能提取出来啊，我是给另一个我使用的编译器做的插件

function jipai(AStr,scel)
    if(string.len(AStr))<1 then
	   return {0,AStr,AStr}
	end
	local zdz
	local p
	if scel=="zhadan" then
	    zdz = {"3333","4444","5555","6666","7777","8888","9999","SSSS","JJJJ","QQQQ","KKKK","1111","2222","AB"}
	    p=14
	elseif scel=="santiao" then
	    zdz = {"333","444","555","666","777","888","999","SSS","JJJ","QQQ","KKK","111","222"}
		p=13
	elseif scel=="duizi" then
	    zdz = {"33","44","55","66","77","88","99","SS","JJ","QQ","KK","11","22"}
		p=13
    elseif scel=="danpai" then
	    zdz = {"3","4","5","6","7","8","9","S","J","Q","K","1","2"}
		p=13
    end
	local result=""
	local resu=""
	local resus=AStr
	for i=1, p do
	    if string.find(AStr,zdz[i]) ~= nil then
		    result = result .. zdz[i].."|"
			resu = resu .. string.gsub(AStr,zdz[i],"",1) .. "|"
			resus = string.gsub(resus,zdz[i],"",1)
		end
	end
	if string.len(result)<1 then
	   return {0,AStr,AStr}
	end
    return {left(string.len(result)-1,result),left(string.len(resu)-1,resu),resus}
end
function left(w,str)
   return string.format("%1." .. w .. "s", str)
end

有个很尴尬的地方，听我一个朋友说的，腾讯课堂上一位老师说，写代码千万别用拼音，宁愿用中文，可是lua我写中文变量变成了特殊符号，不好使，我就用了拼音。

变成“特殊符号”，是编辑器的问题吧…… 没看明白你的“不能提取出来”是指的什么。

懂了，lua写插件真好使，还有字符串匹配真便捷
