我写ASP时常用到的一些函数

对于ASP语言来说，把某一功能模块写成类，那对于效率来讲，未必是件很提倡的事，但是把这种模块化向小了去说，把一些功能写成函数，那就对于在ASP开发的时候，省不少事了，以下是一些我经常用到的函数，有一些是我写的，有的是从网上找的，比如说CFS编码的；网上的CFS编码的函数里面的变量都没声明，所以在我的页面声明了option explicit后就不能正常使用了，很简单，我在FUNCTION里把变量声明了就可以了。

这儿只是一部分，因为我现在在公司，而我的大部分资料都在家里电脑上，以后再补充了……大家如果有什么好的有和的函数，也欢迎和我交流……

'@转换日期为星期几函数

'@idate为标准日期格式

'@itype为0时表示英文星期几,否则为中文

function showweek(idate,itype)

if itype <> 0 then itype = 1 '//防止误输出错

dim inum,nday

inum = weekday(idate)

if itype = 0 then

select case inum

case 1

nday = "Sunday"

case 2

nday = "Monday"
