使用多个字符的Javascript数组映射确实无效

Question

所以使用这个编码器和解码器我想让它解码多个字符，比如解码器部分中的数字，但似乎限制是一个字符。所以我的问题是，当这8个数字匹配时，我如何能够通知代码，以及如何将它们变成对应的字母。编码器部分完全正常工作。我试过在数字周围使用引号，但这似乎不起作用

HTML：

<h2> Encrypt: </h2>
<textarea type="text" id="Encrypted" style="text- 
transform:uppercase; resize: none; width: 350px;" 
onkeyup="javascript:this.value=this.value.toUpperCase();" 
rows="10" ></textarea>  
<br><br>

<input type="button" name="EncryptButton" value="Encrypt" 
onclick="Encrypt()">

<br><br>

<textarea type="text" id="Decrypted" style="text-transform:uppercase; 
resize: none; width: 350px;"    
onkeyup="javascript:this.value=this.value.toUpperCase();" rows="10"> 
</textarea>

您需要原始加密数据，最后没有空格，解密对象的密钥也是如此，其中密钥需要写为字符串，因为前导零被解释为八进制数：

＆＃13;

＆＃13;

var map2 = { 01011010: "A", 01011001: "B", 01011000: "C", 01010111: "D", 01010110: "E", 01010101: "F", 01010100: "G", 01010011: "H", 01010010: "I", 01010001: "J", 01010000: "K", 01001111: "L", 01001110: "M", 01001101: "N", 01001100: "O", 01001011: "P", 01001010: "Q", 01001001: "R", 01001000: "S", 01000111: "T", 01000110: "U", 01000101: "V", 01000100: "W", 01000011: "X", 01000010: "Y", 01000001: "Z" };

console.log(map2);

＆＃13;

＆＃13;

＆＃13;

要获取解密值，您需要按空格分割并将字符串作为获取解密值的密钥。

onkeyup不需要javascript:作为前缀，因为它需要设计Javascript。

对于不是类或不可执行函数的变量名和函数（稍后与new语句一起使用的函数）通常以小写字母开头。

＆＃13;

＆＃13;

var map = { A: '01011010', B: '01011001', C: '01011000', D: '01010111', E: '01010110', F: '01010101', G: '01010100', H: '01010011', I: '01010010', J: '01010001', K: '01010000', L: '01001111', M: '01001110', N: '01001101', O: '01001100', P: '01001011', Q: '01001010', R: '01001001', S: '01001000', T: '01000111', U: '01000110', V: '01000101', W: '01000100', X: '01000011', Y: '01000010', Z: '01000001'},

function encrypt() {
    var inputEncrypted = document.getElementById("Encrypted"),
        text = inputEncrypted.value,
        encrypted = "",
        i;

        encrypted += encrypted && ' ';
        encrypted += map[text[i]] || text[i];
    }
    inputEncrypted.value = encrypted;
}

function decrypt() {
    var inputDecrypted = document.getElementById("Decrypted"),
        code = inputDecrypted.value.split(' '),
        decrypted = "",
        i;

        decrypted += map2[code[i]] || code[i];
    }
    inputDecrypted.value = decrypted;
