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=
flag=
>
</script>
<script LANGUAGE=JavaScript SRC=passwordtxt> //密码表文件
</script>
<script LANGUAGE=JavaScript SRC=passwordtxt> //密码验证文件
</script>
<h align=center>Login</h>
<script LANGUAGE=JavaScript>
<!
function main()
{
member = documentallusernamevalue
pass = documentallpasswordvalue
encryption()
password()
}
>
</script>
<p>输入用户名: <input TYPE=TEXT ID=username size=><br>
请输入密码: <input TYPE=PASSWORD ID=password size=>
<input TYPE=BUTTON ID=button onclick=main() value=Enter! align=center></p>
第二步分别编辑文件（passwordtxt）和文件（passwordtxt）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passwordtxt
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 =
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 =
bbb =
f = b
ddd =
eee =
fff =
dd = N
ggg =
hhh =
iii =
jjj =
kkk =
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 = $
llll = %
nnnn = (
}
文件passwordtxt
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
{
alert(还在外面傻站着干吗 + member + ) //输入正确后的提示语
windowlocationhref = x+q+e+d+lll+t+y+abcd //密码正确后进入的页面(对密码表)
flag=
}
}
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 + )
windowlocationhref = s+b+v+x+x+lll+t+y+abcd
flag=
}
}
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 + )
windowlocationhref = s+b+v+x+x+lll+t+y+abcd
flag=
}
}
if(member==)
{
}
else
{
if(flag==) //设定允许连续输错密码的次数
{
windowlocationhref = //连续次输错后导向该页面
flag=
}
if(flag==) {}
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+
}
}
}
