Lua 常用遍历

b = {}
for i=1, 10 do
    b[i] = i
end

-- method one
for i, v in pairs(b) do 
    print (i, v)
end


-- method two 
for i, v in ipairs(b) do 
    print (i, v)
end

-- method three 
for i = 1, #b  do 
    print (i, b[i]) 
end

-- method four
for i = 1, table.maxn(b) do 
    print (i, b[i])
end

lua常用的四种遍历，前两种是泛型遍历，后两种是数值的遍历.
