【HTML】输入密码访问

<script>
(function(){
    if('{{ page.password }}'){
        if (prompt('请输入文章密码') !== '{{ page.password }}'){
            alert('密码错误！');
            history.back();
        }
    }
})();
</script>

代码一：
<script type="text/javascript">
function password() {
var testV = 1;
var pass1 = prompt('请输入密码','');
while (testV < 3) {
if (!pass1)
history.go(-1);
if (pass1 == "123") {//初始密码123
alert('密码正确!');
break;
}
testV+=1;
var pass1 =
prompt('密码错误!请重新输入:');
}
if (pass1!="password" & testV ==3)
history.go(-1);
return " ";
}
document.write(password());
</script>  

代码二：
<script type="text/javascript">
function password() {
var testV = 1;
var pass1 = prompt('Sorry,该页只限熟人浏览,请输入密码:','');
while (testV < 3) {
if (!pass1)
history.go(-1);
if (pass1 == "123") {//初始密码123
alert('一看你就是自己人，口令正确!');
window.location.href="http://www.aeink.com";//修改需要密码认证的网页
break;
}
testV+=1;
var pass1 =
prompt('朋友，密码不对！:(','');
}
if (pass1!="password" & testV ==3)
history.go(-1);
return " ";
}
document.write(password());
</script>  

代码三：
<script type="text/javascript">
loopy()
function loopy() {
var sWord =""
while (sWord != "123") {//初始密码123
sWord = prompt("输入正确密码才能登陆!")
}
alert("AH…欢迎光临！")
}
</script>  

把上述代码加到网页头部模版 /head 标签前即可.
