文/周庆 我们经常会遇到一些必须输入用户名和密码才能进入的网站。其实我们也可以对自己的网站页面进行简单的加密，具体操作请看下文： 第一步：创建密码登录页 将如下代码加入HTML的<BODY>区： <script LANGUAGE="JavaScript"> <!-- flag=0 flag2=0 --> </script> <script LANGUAGE="JavaScript" SRC="password.txt"> //密码表文件 </script> <script LANGUAGE="JavaScript" SRC="password1.txt"> //密码验证文件 </script> <h1 align="center">Login</h1> <script LANGUAGE="JavaScript"> <!-- function main() { member = document.all.username.value pass = document.all.password.value encryption() password() } --> </script> <p>输入用户名: <input TYPE="TEXT" ID="username" size="20"> <br> 请输入密码: <input TYPE="PASSWORD" ID="password" size="20"> <input TYPE="BUTTON" ID="button" onclick="main()" value="Enter!" align="center"> </p> 第二步：分别编辑文件1（password.txt）和文件2（password1.txt），适合你自己的页面情况，主要是密码设定和用户名设定。 文件1：password.txt 一张密码表，一看就懂，没有什么难度。可以自由设计，注意大小写的区别。 function encryption() { mm = "Z" k = "j" b = "p" mmmm = "&" ccc = "6" l = "i" c = "q" m = "s" abcd = "m" o = "n" u = "z" e = "d" gg = "U" p = "u" jj = "O" v = "a" j = "y" x = "c" r = "n" bb = "D" cc = "K" z = "w" a = "x" ee = "G" n = "f" ff = "T" i = "g" w = "r" ii = "V" kk = "I" q = "o" oooo = ")" d = "e" nn = "E" oo = "P" pp = "X" t = "h" s = "v" rr = "S" ss = "L" tt = "R" uu = "A" h = "k" vv = "C" ww = "M" aa = "Y" xx = "Q" hh = "B" yy = "H" zz = "W" y = "t" qq = "J" aaa = "8" bbb = "0" f = "b" ddd = "9" eee = " " fff = "3" dd = "N" ggg = "4" hhh = "1" iii = "2" jjj = "7" kkk = "5" lll = "." mmm = "，" nnn = ";" ooo = ":" ppp = "'" qqq = "<" rrr = ">" sss = "-" ttt = "_" uuu = "=" vvv = "/" www = "?" xxx = "`" yyy = "~" zzz = "*" aaaa = "+" bbbb = "[" cccc = "]" g = "l" dddd = "{" eeee = "}" ffff = "" gggg = "|" hhhh = "!" iiii = "@" jjjj = "#" kkkk = "code:quot; llll = "%" nnnn = "(" } 文件2：password1.txt function password() { if(member==i+p+d+m+y) //第一个用户名；对照密码表翻译为：guest { if(pass==hhh+iii+fff+ggg) //第一个密码；对照密码表翻译为：1234 { alert("还在外面傻站着干吗 " + member + "...") //输入正确后的提示语 window.location.href = x+q+e+d+lll+t+y+abcd //密码正确后进入的页面code.htm(对密码表) flag2=1 } } if(member==k+v+j) //设定第二个用户名，以下类推... { if(pass==f+i+p+d) { alert("还在外面傻站着干吗 " + member + "...") window.location.href = s+b+v+x+x+lll+t+y+abcd flag2=1 } } if(member==qqq+llll+ttt+llll+rrr) //设定第三个用户名，以下类推... { if(pass==ooo+sss+oooo) { alert("还在外面傻站着干吗 " + member + "...") window.location.href = s+b+v+x+x+lll+t+y+abcd flag2=1 } } if(member=="") { } else { if(flag==3) //设定允许连续输错密码的次数 { window.location.href = "http://cn.geocities.com/enetvhome" //连续3次输错后导向该页面 flag2=1 } if(flag2==1) else { alert ("对不起，今天我心情不好，在外面待会儿吧！") //输错密码后的警示语 flag=flag+1 } } }
