主要代码如下：

function POP_sqlin(text)  
  if isnull(text) then
    POP_sqlin=""
    exit function
  end if

  dim Sqlwords

  Sqlwords.Pattern="(')"
  text=Sqlwords.Replace(text,"''")
  Sqlwords.Pattern="(;)"
  text=Sqlwords.Replace(text,"；")
  Sqlwords.Pattern="(%)"
  text=Sqlwords.Replace(text,"％")
  Sqlwords.Pattern="(and)"
  text=Sqlwords.Replace(text,"ａｎｄ")
  Sqlwords.Pattern="(exec)"
  text=Sqlwords.Replace(text,"ｅｘｅｃ")

  Set Sqlwords=Nothing
  POP_sqlin = text
end function

function POP_sqlout(text)  
  if isnull(text) then
    POP_sqlout=""
    exit function
  end if
  text = Replace(text,"''","'")

  POP_sqlout = text
end function

function HTMLEncode(popstring)

使用方法：
把需要过滤的提交信息改为POP_sqlin(提交的信息)即可
在需要把信息还原时改为：Htmlencode(提交的信息)即可
