Lua 特定字元擷取字串

記錄下工作中用到lua的乙個簡單功能需求：

如下字串："aa,bb;cc,dd;ee,ff;gg,hh;"

轉成：表形式。

function combination(sourcestr)

if not sourcestr or sourcestr == "" then
print("特定字串轉成指定表出錯!")
return
endlocal outsplitchar = ";"
local innersplit = ","
local function inner_get_table_from_split_string(src, splitchar)
local splitlist = {}
string.gsub(src, '[^' .. splitchar ..']+', function(value) table.insert(splitlist, value) end)
return splitlist
endlocal out_tbl = inner_get_table_from_split_string(sourcestr, outsplitchar)
local tmp={}
for _, value in pairs(out_tbl) do
local tmp_tbl = inner_get_table_from_split_string(value, innersplit)
local inner_tbl = {}
inner_tbl["" .. tmp_tbl[1]] = tonumber(tmp_tbl[2])
tmp[#tmp + 1] = inner_tbl
endlocal final_tbl = {}
for k, v in pairs(tmp) do
final_tbl[table.keys(v)[1]] = table.values(v)[1]
endreturn final_tbl
end
