前言
有小伙伴提了个需求:说网站放 Github Page 上,但不想人人都能访问,怎样用做一个密码加密,比如输入6位密码,密码输入正确自动跳转,错误给出提示?
实现
这个可以用HTML加JS写一个密码输入框,在正确输入密码前阻断内容显示,糊弄下小白还是可以的,画面也比较简洁。
简单实用密码弹出框
在模板或者HTML页头位置加入如下代码,只要是内容显示前就行:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
| <script language = JavaScript> function password() { var testV = 1; var pass1 = prompt('请输入密码:', ''); while (testV < 3) { if (!pass1) history.go(-1); if (pass1 == "123456") { 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>

逼格稍微高点的页面密码框
body里面的代码
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
| <span style="font-family: 黑体;">请输入密码:</span><input id="password" type="password" name="密码输入框"/> <table width="300" height="300" style="text-align: center;"> <tr> <td id="1" onmouseenter="doenter(this)" onmouseout="doout(this)" onmousedown="dodown(this)" onmouseup="doup(this)">1</td> <td id="2" onmouseenter="doenter(this)" onmouseout="doout(this)" onmousedown="dodown(this)" onmouseup="doup(this)">2</td> <td id="3" onmouseenter="doenter(this)" onmouseout="doout(this)" onmousedown="dodown(this)" onmouseup="doup(this)">3</td> </tr> <tr> <td id="4" onmouseenter="doenter(this)" onmouseout="doout(this)" onmousedown="dodown(this)" onmouseup="doup(this)">4</td> <td id="5" onmouseenter="doenter(this)" onmouseout="doout(this)" onmousedown="dodown(this)" onmouseup="doup(this)">5</td> <td id="6" onmouseenter="doenter(this)" onmouseout="doout(this)" onmousedown="dodown(this)" onmouseup="doup(this)">6</td> </tr> <tr> <td id="7" onmouseenter="doenter(this)" onmouseout="doout(this)" onmousedown="dodown(this)" onmouseup="doup(this)">7</td> <td id="8" onmouseenter="doenter(this)" onmouseout="doout(this)" onmousedown="dodown(this)" onmouseup="doup(this)">8</td> <td id="9" onmouseenter="doenter(this)" onmouseout="doout(this)" onmousedown="dodown(this)" onmouseup="doup(this)">9</td> </tr> </table>

js代码
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
| var password = 123456; var input = document.getElementById("password"); var td = document.getElementsByTagName("td"); for(var i = 0;i < td.length;i++){ td[i].style.color = "white" td[i].style.backgroundColor = "#EAEAEA"; td[i].style.borderRadius = "50px"; } function dodown(obj){ obj.style.backgroundColor = "darkgray"; input.value += obj.id; } function doup(obj){ obj.style.backgroundColor = "#EAEAEA"; if(input.value.length == 6){ if(input.value == password){ alert("登录成功"); location.href="https://sobaigu.com"; }else{ alert("密码错误,登录失败") input.value = null; } } } function doenter(obj){ obj.style.backgroundColor = "lightgray"; } function doout(obj){ obj.style.backgroundColor = "#EAEAEA"; }
