注意：此代码类似于与html相关的代码。这是私事 偏好
这是功能Runner（）中的循环。经过2个小时的尝试，尝试了诸如
function runner () {
var entext = [];
var p = 0;
var abc = document.getElementById('input');
var ab = abc.length;
while (p <= ab) {
entext.push(document.getElementById('input').value[p]);
document.getElementById('runEncryption').innerHTML = entext[p];
p++;
}
alert(ab); //If this was in the loop, it won't work
}
循环结构
function runner () {
var entext = [];
for (var p = 0; p <= getElementById('input').length; p++) {
entext.push(document.getElementById('input').value[p]);
document.getElementById('runEncryption').innerHTML = entext[p];
}
}
用于循环结构
两者之间的所有内容也不起作用。在循环之外，代码可以工作，但是我需要将循环开放到用户输入的文本限制。 似乎循环无法将getElement代码处理为合适的值。 如何解决此错误？
答案 0 :(得分：0)
这是一种更简洁的方法，将更轻松地支持编码和解码方法。 我们将chars存储在位置为代码的数组中。允许使用两种方式进行映射。
// Simple array of chars where their index is the 'code'
let lexicon = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "~", "`", "!", "@", "#", "$", "%", "^", "&", "*", "(", ")", ">", "<", "-", "_", "+", "=", "{", "", "[", "]", "|", ",", ".", "?", "/", "'", '"', "", ";", " "];
// Function to take a string and encode it using a simple map.
const encodeData = (data, lex) => data.split('').map(c => lex.indexOf(c) + 1);
// Decode does the reverse
const decodeData = (data, lex) => data.map(d => lex[d]);
var encryption = [];
var cvalue = 0;
var code = prompt("Type In Encryption Password [Beta Encryptor]");
alert(encodeData(code, lexicon));
function runner() {
var abc = document.getElementById('input').value;
encryption = encodeData(abc,lexicon);
if (encryption.length % 2 === 1) {
encryption.push(93);
alert("The Key was Edited Because The Key needs to be even");
}
document.getElementById('runEncryption').innerHTML = encryption.join();
alert(encryption); //If this was in the loop, it won't work
