lua split

                         local function Split2(szFullString,szSeparator)
local nFindStartIndex = 1
local nSplitIndex = 1
local nSplitArray = {}
while true do
  local nFindLastIndex = string.find(szFullString,szSeparator,nFindStartIndex)
  if not nFindLastIndex then
nSplitArray[nSplitIndex] = string.sub(szFullString,nFindStartIndex,string.len(szFullString))
break
  end
  nSplitArray[nSplitIndex] = string.sub(szFullString,nFindLastIndex - 1)
  nFindStartIndex = nFindLastIndex + string.len(szSeparator)
  nSplitIndex = nSplitIndex + 1
end
return nSplitArray

       end

用法：

 local recvDatas= Split2(s,",")  NET.state= tonumber(recvDatas[1])--一定要从1开始
