第一步:把如下代码加入<head>区域中
<SCRIPT LANGUAGE="JavaScript">
<!-- Hide
al="`1234567890-=~!@#$%^&*()_+qwer"
+"tyuiop[]QWERTYUIOP{}|asdfghjkl;A"
+"SDFGHJKL:zxcvbnm,./ZXCVBNM<>?";
ab1="";
bctr=0;
function ckPwd(){
 tst=document.isn.username.value
 +"*"+document.isn.passwrd.value+"*";
 ls=document.pd.pe.value;
 a=eval(ls.substring(0,2))-91;
 ls=ls.substring(2,ls.length);
 nls="";
 flg=0;
 while (ls.length>12){
  ab=eval(ls.substring(0,2))-89;
  ab1=(ab1==""?""+ab:ab1);
  oab1=ab1;
  ls=ls.substring(2,ls.length);
  for (var i=0;i<ab;i++){
   nr=eval(ls.substring(0,2))-a;
   ls=ls.substring(2,ls.length);
   nls+=al.charAt(nr);
   }
  nls+="*";
  if (nls.indexOf(tst)>-1){
   ls="";
   flg=1;
   }
  }
 if (flg==1){
  tstOk();
  }
 else{
  bctr++;
  if (bctr>3){
   location.href="nopass.htm";
   }
  else{
   alert("对不起,用户名/密码错误."
   +" 你已试登录"+bctr+"次.");
   }
  }
 }

function tstOk(){
 ab1=ab1+""+a;
  alert("正确，开始登录!");
  location.href="pwds.htm?"+ab1;
 }

// End Hiding -->
</SCRIPT>

第二步:把如下代码加入<body>区域中
<FORM NAME="pd">
