几个常用的ASP函数

鉴于大家对ASP十分关注，我们编辑小组在此为大家搜集整理了“几个常用的ASP函数”一文，供大家参考学习

========取得带端口的URL，推荐使用================
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



''=================用正则表达式突出显示字符串中查询到的单词的函数======================
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



''===============取得用户当前IP地址===================
Function GetIP()
uIP = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
If uIP = "" Then uIP = Request.ServerVariables("REMOTE_ADDR")
GetIp = uIP
End Function

''===============取得当前程序脚本路径==================
Function GetScriptName()
ScriptAddress = CStr(Request.ServerVariables("SCRIPT_NAME"))''取得当前地址
If (Request.QueryString <> "") Then
ScriptAddress = ScriptAddress & "?" & Server.HTMLEncode(Request.QueryString)''取得带参数地址
End If
If Len(ScriptAddress)>250 Then ScriptAddress = Left(ScirptAddress,250)&"..." ''进行路径截取，最大为250个字符
GetScriptName = ScriptAddress
End Function




''===========返回带参数的Url，多关键字排序时使用==============
'' RemoveList 参数：需要从Url中去除的参数，可以是多个，中间请用逗号隔开
Function KeepUrlStr(RemoveList)
ScriptAddress = CStr(Request.ServerVariables("SCRIPT_NAME"))&"?"''取得当前地址,并加入“?”符号
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
