给你一段代码，过滤输入特殊符号，保治百病(:)

   function eck(str)
    rem 检查过滤所有的输入
    dim dist
    dist=replace(str,"","")
    dist=replace(dist,"<","<")
    dist=replace(dist,">",">")
    dist=replace(dist,"chr(60)","<")
    dist=replace(dist,"chr(37)",">")
    dist=replace(dist,"""",""")
    dist=replace(dist,";",";;")
    eck=dist
   end function

sub showbody(str)多行文本显示函数
    str=replace(str,chr(13),"<br>" & chr(13)+chr(10))
    str=replace(str,chr(32)," ")
    response.write str
end sub
