asp之自动闭合HTML ubb标签函数附简单解释:

Function closeUBB(strContent)

'*************************************

'自动闭合UBB

'*************************************

Dim arrTags, i, OpenPos, ClosePos, re, strMatchs, j, Match

Set re = New RegExp '申明re对象

re.IgnoreCase = True '设置是否区分字符大小写

re.Global = True '设置全局可用性

arrTags = Array("code", "quote", "list", "color", "align", "font", "size", "b", "i", "u", "html") '建立数组，存储相关需要检测是否闭合的标签

For i = 0 To UBound(arrTags) '循环对数组里的每一个元素进行检测

OpenPos = 0 '初始化当前标签开始标记的个数

ClosePos = 0 '初始化当前标签结束标记的个数

re.Pattern = "/[" + arrTags(i) + "(=[^/[/]]+|)/]" '开始分别正则判断开始与结束标记的个数

Set strMatchs = re.Execute(strContent)

For Each Match in strMatchs

OpenPosOpenPos = OpenPos + 1

Next

re.Pattern = "/[/" + arrTags(i) + "/]"

Set strMatchs = re.Execute(strContent)

For Each Match in strMatchs

ClosePosClosePos = ClosePos + 1

Next

For j = 1 To OpenPos - ClosePos '当开始与结束标记数量不一致时，闭合当前标签

strContentstrContent = strContent + "[/" + arrTags(i) + "]"

Next

Next

closeUBB = strContent

Set re = Nothing

End Function

程序代码

Function closeHTML(strContent)
