ASP常用的函数 |
ASP常用的函数,希望能用的着 。 <% dim db db="dbms.mdb" ****************************************************************** 执行sql语句,不返回值,sql语句最好是如下: update 表名 set 字段名=value,字段名=value where 字段名=value delete from 表名 where 字段名=value insert into 表名 (字段名,字段名) values (value,value) ****************************************************************** Sub NoResult(sql) dim conn dim connstr Set conn = Server.CreateObject("ADODB.Connection") connstr="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(""&db&"") conn.Open connstr conn.execute sql conn.close set conn=nothing End Sub ******************************************************************* 执行select语句,返回recordset对象 。该对象只读 。也就是不能更新 ******************************************************************* Function Result(sql) dim conn dim connstr dim rcs Set conn = Server.CreateObject("ADODB.Connection") connstr="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(""&db&"") conn.Open connstr Set rcs = Server.CreateObject("ADODB.Recordset") rcs.open sql,conn,1,1 set Result = rcs End Function ******************************************************************* 弹出对话框 ******************************************************************* Sub alert(message) message = replace(message,"","\") Response.Write ("<script>alert(" & message & ")</script>") End Sub ******************************************************************* 返回上一页,一般用在判断信息提交是否完全之后 ******************************************************************* Sub GoBack() Response.write ("<script>history.go(-1)</script>") End Sub ******************************************************************* 重定向另外的连接 ******************************************************************* Sub Go(url) Response.write ("<script>location.href(" & url & ")</script>") End Sub ******************************************************************* 把html标记替换 ******************************************************************* function htmlencode2(str) dim result dim l if isNULL(str) then htmlencode2="" exit function end if l=len(str) result="" dim i for i = 1 to l select case mid(str,i,1) case "<" result=result+"<" case ">" result=result+">" case chr(13) result=result+"<br>" case chr(34) result=result+""" case "&" result=result+"&" case chr(32) result=result+" " if i+1<=l and i-1>0 then if mid(str,i+1,1)=chr(32) or mid(str,i+1,1)=chr(9) or mid(str,i-1,1)=chr(32) or mid(str,i-1,1)=chr(9) then result=result+" " else result=result+" " end if else result=result+" " end if case chr(9) result=result+" " case else result=result+mid(str,i,1) end select next htmlencode2=result end function ******************************************************************* 检查sql字符串中是否有单引号,有则进行转化 ******************************************************************* function CheckStr(str) dim tstr,l,i,ch str = Trim(str) l=len(str) for i=1 to l ch=mid(str,i,1) if ch="" then tstr=tstr+"" end if tstr=tstr+ch next CheckStr=tstr end function %> |
