我在后台添加详细页时用”---“把文本字段(content)分成了几块,我按照网友的指示用SPLITE函数查找设置好的分页符,并用FOR循环将动态详细页字段分割。找了一段代码,还是不懂,可能是代码太简单,又不知道应该在什么位置插。下面将详细页源代码和函数简单的代码复制如下。希望高手能够在百忙之中给予解答!

网友给的简单分页代码:

 

MMText=replace(rs("字段"),"---","---")
if MMText
<>"" then
MMfText=split(MMText,"---")
for i=pageNum to pageNum
MMfText(i)
next
end if

你贴的ASP代码真不好解释,太长了,估计大家都没心思看完。

请您对以下的函数替换和FOR循环的代码看一下。我设的分页符为“---”,具体还要怎样完善代码,才能实现您所说的替换成HTML分页代码。具体在那儿插呢? MMText=replace(rs("字段"),"---","---") if MMText<>"" thenMMfText=split(MMText,"---") for i=pageNum to pageNumMMfText(i) next end if
