转换字符串带有http://的超级链接字符串为真正的超级链接(源码)

Code Title: Auto-linking
Description: How would you like to have every instance of an http:// auto-hyperlink itself to the URL
address that follows it? Well, here is a killer little function that will take every one of those that it
finds in a string and sets up the hyperlink for you! Cool, eh?
Copy and paste this snippet as-is into your editor:

-------------------------------------------------------------------------
<%
Function LinkURLs(strInput)
iCurrentLocation = 1
Do While InStr(iCurrentLocation, strInput, "http://", 1) <> 0
iLinkStart = InStr(iCurrentLocation, strInput, "http://", 1)
iLinkEnd = InStr(iLinkStart, strInput, " ", 1)
If iLinkEnd = 0 Then iLinkEnd = Len(strInput) + 1
Select Case Mid(strInput, iLinkEnd - 1, 1)
Case ".", "!", "?"
iLinkEnd = iLinkEnd - 1
End Select
strOutput = strOutput & Mid(strInput, iCurrentLocation, iLinkStart - iCurrentLocation)
strLinkText = Mid(strInput, iLinkStart, iLinkEnd - iLinkStart)
strOutput = strOutput & "<a href="""&strLinkText&""">"&strLinkText&"</a>"
iCurrentLocation = iLinkEnd
Loop
strOutput = strOutput & Mid(strInput, iCurrentLocation)
LinkURLs = strOutput
End Function
strUnlinked = "http://LINE9.com rules! <br>" & vbCrLf
strUnlinked = strUnlinked & "http://pdxpc.com sells great computers!<br>" & vbCrLf

Here is the before text:
Response.Write "<b>Original Text:</b><br>" & vbCrLf
Response.Write strUnlinked
Response.Write vbCrLf & "<br>" & vbCrLf & vbCrLf

Here is the text after it gets automatically hyperlinked to itself:
Response.Write "<b>Text After Linking:</b><br>" & vbCrLf
Response.Write LinkURLs(strUnlinked)
