Answer 1

可以对提交的内容进行处理!

过滤js html iframe代码

下面给你一个处理函数

程序代码
'===========================
'函数名：RemoveHtml
'作用：移除HTML｜Iframe｜有害字符
'参数：OriginStr(需要处理的字符串)
' RemoveLevel(移除等级 0:全部移除｜1:只移除Iframe｜2:移除Iframe和JS｜3:移除有害字符)
'===========================
Public Function RemoveHTML(ByVal originStr,ByVal RemoveLevel)
Dim Str,Reg
Str=OriginStr
On Error Resume Next
Set Reg=New RegExp
Reg.IgnoreCase=True
Reg.Global=True
Select Case RemoveLevel
Case 0
Reg.Pattern = "<(.[^>]*)>"
Str = Reg.Replace(Str, "")
Case 1
Reg.Pattern = "(<iframe(.+?)<\/iframe>)"
Str = Reg.Replace(Str,"")
Case 2
Reg.Pattern = "(<s+cript(.+?)<\/s+cript>)"
Str = Reg.Replace(Str, "")
Reg.Pattern = "(<iframe(.+?)<\/iframe>)"
Str = Reg.Replace(Str,"")
Case 3
Reg.Pattern = "[^\s\w]"
Str = Reg.Replace(Str,"")
End Select
Set Reg = Nothing
RemoveHTML=Str
End Function
