Lua中用Split函数分割字符串

复制代码 1 function Split(szFullString, szSeparator) 2 local nFindStartIndex = 1 3 local nSplitIndex = 1 4 local nSplitArray = {} 5 while true do 6 local nFindLastIndex = string.find(szFullString, szSeparator, nFindStartIndex) 7 if not nFindLastIndex then 8 nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, string.len(szFullString)) 9 break 10 end 11 nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, nFindLastIndex - 1) 12 nFindStartIndex = nFindLastIndex + string.len(szSeparator) 13 nSplitIndex = nSplitIndex + 1 14 end 15 return nSplitArray 16 end

function Split(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, nFindStartIndex, nFindLastIndex - 1)

nFindStartIndex = nFindLastIndex + string.len(szSeparator)

nSplitIndex = nSplitIndex + 1
end
return nSplitArray
end

用法:

local list = Split("abc,123,345", ",")

然后list里面就是

abc
123
345

第二个参数可以是多个字符，但是不能是Lua正则表达式。例如. ，或者 %w 之类的。
