ASP函數在asp網頁編程實現功能中是必需部分，但是你對ASP函數了解嗎？其實我們只要掌握幾個常用的ASP函數即可，那么我們現在就去看看常用ASP函數的介紹。

========取得帶端口的URL，推薦使用================?
Function?Get_ScriptNameUrl()?
If?request.servervariables("SERVER_PORT")="80"?Then?
Get_ScriptNameUrl="http://"?&?request.servervariables("server_name")&lcase(request.servervariables("script_name"))?
Else?
Get_ScriptNameUrl="http://"?&?request.servervariables("server_name")&":"&request.servervariables("SERVER_PORT")&lcase(request.servervariables("script_name"))?
End?If?
End?Function?
上文就是常用ASP函數的介紹，看完后你對ASP函數了解了嗎？


'=================用正則表達式突出顯示字符串中查詢到的單詞的函數======================?
Function?BoldWord(strContent,word)?
If?word=""?Then?
BoldWord?=?strContent?
Exit?Function?
End?IF?
dim?objRegExp?
Set?objRegExp=new?RegExp?
objRegExp.IgnoreCase?=true?
objRegExp.Global=True?

objRegExp.Pattern="("?&?word?&?")"?
strContent=objRegExp.Replace(strContent,"<font?color=""#FF0000""><b>$1</b></font>"?)?

Set?objRegExp=Nothing?
BoldWord=strContent?
End?Function?



'===============取得用戶當前IP地址===================?
Function?GetIP()?
uIP?=?Request.ServerVariables("HTTP_X_FORWARDED_FOR")?
If?uIP?=?""?Then?uIP?=?Request.ServerVariables("REMOTE_ADDR")?
GetIp?=?uIP?
End?Function?

'===============取得當前程序腳本路徑==================?
Function?GetScriptName()?
ScriptAddress?=?CStr(Request.ServerVariables("SCRIPT_NAME"))'取得當前地址?
If?(Request.QueryString?<>?"")?Then?
ScriptAddress?=?ScriptAddress?&?"?"?&?Server.HTMLEncode(Request.QueryString)'取得帶參數地址?
End?If?
If?Len(ScriptAddress)>250?Then?ScriptAddress?=?Left(ScirptAddress,250)&"..."?'進行路徑截取，最大為250個字符?
GetScriptName?=?ScriptAddress?
End?Function?




'===========返回帶參數的Url，多關鍵字排序時使用==============?
'?RemoveList?參數：需要從Url中去除的參數，可以是多個，中間請用逗號隔開?
Function?KeepUrlStr(RemoveList)?
ScriptAddress?=?CStr(Request.ServerVariables("SCRIPT_NAME"))&"?"'取得當前地址,并加入“?”符號?
M_ItemUrl?=?""?
For?Each?M_item?In?Request.QueryString?
If?InStr(RemoveList,M_Item)=0?Then?
M_ItemUrl?=?M_ItemUrl?&?M_Item?&"="&?Server.URLEncode(Request.QueryString(""&M_Item&""))?&?"&"?
End?If?
Next?
KeepUrlStr?=?ScriptAddress?&?M_ItemUrl?
End?Function?
