asp数组cookies操作函数

本文的创造性在于cookies_to_array(c)   直接简单快捷转化字符串为数组的方法
另外 本文操作的数组 不是 asp普通的多维数组 而是锯齿型的
这种数组 更易操作 更易阅读 行列清晰 很像数据库中的表
可以类比为 datatable
class myarray
'必须为锯齿数组array(array(1,2,3))
function array_to_cookies(a)
dim b(),i,j,u
u = ubound(a)
redim b(u)
for i=0 to u
array_rep a(i)
b(i)=join(a(i),",")
next
array_to_cookies=join(b,";")
end function
sub array_rep(a)
dim i
if isarray(a) then
for i=0 to ubound(a)
if instr(a(i),",")>0 then a(i)=replace(a(i),",","")
if instr(a(i),";")>0 then a(i)=replace(a(i),";","")
next
end if
end sub
function cookies_to_array(c)
c = "array(array("+replace(c,";","),array(")+"))"
execute "cookies_to_array="&c
end function
