今天我遇到了我的旋转密码加密网站的问题。它应该询问类型（ROT1，ROT2，ROT3等）以及是否要加密或解密。然后你必须输入信息，它会提醒结果。即使解密部分有效，加密部分也不会。我的代码如下：旋转密码加密不加密

Enter the message: <input type="text" name="message">

<input type="button" value="encrypt/decrypt" onClick="sendMessage(this.form)">

</div>
</body>
</html>
CSS：
body, html {
height: 100%;
width: 100%;
margin: 0px;
overflow: hidden;
}
#choose_rot {
display: inline;
padding: auto;
}
#encrypt_decrypt {
display: inline;
position: absolute;
top: 50%;
left: 50%;
margin-left: -20%;
margin-top: -37.5px;
width: 100%;
}
#message {
display: inline;
position: absolute;
top: 50%;
left: 50%;
margin-left: -10%;
margin-top: -100px;
width: 100%;
}
#form {
width: 15%;
height: 75px;
line-height: 75px;
font-size: 25px;
margin: 2.5%;
background-color: red;
float: left;
text-align: center;
}
.rot_button, .encrypt_decrypt_button {
width: 15%;
height: 75px;
line-height: 75px;
font-size: 25px;
margin: 2.5%;
background-color: red;
float: left;
text-align: center;
}
而且最重要的组成部分，使用Javascript/JQuery的：
$(document).ready(function() {
$("#encrypt_decrypt, .encrypt_decrypt_button, #message").fadeOut(0);
var rotation;
var type;
$(".rot_button").click(function() {
window.rotation = $(this).attr("id");
$("#choose_rot, .rot_button").fadeOut("slow", function() {
$("#encrypt_decrypt, .encrypt_decrypt_button").fadeIn("slow");
});
});
$(".encrypt_decrypt_button").click(function() {
window.type = $(this).attr("id");
$("#encrypt_decrypt, .encrypt_decrypt_button").fadeOut("slow", function() {
$("#message").fadeIn("slow");
});
});
});
function sendMessage(form) {
var message = form.message.value;
message.toLowerCase();
var ascii_message = new Array();
var ascii_encrypted_message = new Array();
var encrypted_message = new Array();
for (i=0;i < message.length; i++) {
ascii_message[i] = message.charCodeAt(i);
}
for (i=0;i < message.length; i++) {
if ( (ascii_message[i] >= 97) && (ascii_message[i] <= 122) ) {
if (type == "decrypt") {
var new_message = ascii_message[i] + rotation;
if (new_message > 122) {
new_message = new_message - 26;
ascii_encrypted_message[i] = new_message;
encrypted_message[i] = String.fromCharCode(ascii_encrypted_message[i]);
alert(encrypted_message.join(""));
}
else {
ascii_encrypted_message[i] = new_message;
encrypted_message[i] = String.fromCharCode(ascii_encrypted_message[i]);
alert(encrypted_message.join(""));
}
}
else if (type == "encrypt") {
var new_message = ascii_message[i] - rotation;
if (new_message < 97) {
new_message = new_message + 26;
ascii_encrypted_message[i] = new_message;
encrypted_message[i] = String.fromCharCode(ascii_encrypted_message[i]);
alert(encrypted_message.join(""));
}
else {
ascii_encrypted_message[i] = new_message;
encrypted_message[i] = String.fromCharCode(ascii_encrypted_message[i]);
alert(encrypted_message.join(""));
}
}
}
else {
alert("HELLO!");
}
}
}
任何人都可以或许帮助我解决这个问题时，加密部分几乎与解密部分相同。唯一的区别是ascii_message [i]和轮转之间的负数。

请注意，您为Encrypt＆Decrypt按钮设置了“id”错误。 –
