Lua自己实现string.split功能

local function split(str, d) --str是需要查分的对象 d是分界符

local lst = { }

local n = string.len(str)--长度

local start = 1

while start <= n do

local i = string.find(str, d, start) -- find 'next' 0

if i == nil then

table.insert(lst, string.sub(str, start, n))

break

end

table.insert(lst, string.sub(str, start, i-1))

if i == n then

table.insert(lst, "")

break

end

start = i + 1

end

return lst

end

另一种：用指定字符或字符串分割输入字符串，返回包含分割结果的数组：

from: http://blog.csdn.net/heyuchang666/article/details/51700017
function string.split(input, delimiter)

input = tostring(input)

delimiter = tostring(delimiter)

if (delimiter=='') then return false end

local pos,arr = 0, {}

-- for each divider found

for st,sp in function() return string.find(input, delimiter, pos, true) end do

table.insert(arr, string.sub(input, pos, st - 1))

pos = sp + 1

end

table.insert(arr, string.sub(input, pos))

return arr

end
